The Gemtek Systems P-520 is a Carrier-Grade Wi-Fi Access Point designed to provide reliable and secure wireless access to an operator network or enterprise LAN. Theft-proof mounted to a wall or ceiling the access point can be fully configured and controlled from a central management system minimizing the need for an engineer to physically access the unit once it has been installed. Product Overview High Performance for Maximum Coverage The Gemtek Systems P-520 Operator Access Point provides quality connectivity for Wi-Fi networks. Designed to support even the largest of Hot Spots, this AP combines high receiver sensitivity and proven antenna technology to maximize coverage. Wi-Fi Compliance to Ensure Network Compatibility Tested for interoperability with the Wi-Fi standard, the P-520 will support all Wi-Fi certified client devices; the global industry-standard for local wireless networking. The Perfect Access Point for Large Areas The P-520 is specifically designed for large venues. Connected to a Access Controller like the Gemtek Systems G6000 or P-560, P-520s can easily cover a hotspot of any size. P-520 is IEEE 802.3af compliant, enabling it to be powered over standard Cat-5 Ethernet cabling, reducing installation and maintenance costs. Total Management The P-520 Operator Access Point simplifies the set-up, operation, control and management of public access networks. The AP can be remotely managed via HTTP or SNMP. Auto-channel selection and integrated site survey utilities help administrators to optimize cell planning. Security P-520 supports various state-of-the-art security mechanisms like WPA, Access Control Lists, 802.1x/EAP authentication and Layer 2 User Isolation. The User Isolation feature can effectively prevent peer-to-peer communication between client stations. The AP is designed for wall mount with integrated theft-protection. Gemtek Systems Page 9 User’s Guide Chapter 1 – Introduction Management Options There are several managing and monitoring interfaces available to the operator to configure and manage the P-520 on your network: Web-browser Interface SNMP Management (SNMP v1, v2c) This user manual provides detailed description of Web and SNMP management option. Web Interface The Web-browser interface (also known as the HTTP interface) provides easy access to configuration settings and network statistics from any computer in the network. Use the Web browser interface through your LAN (switch, hub, etc.), over the Internet, or with a “crossover” Ethernet cable connected directly to your computer’s Ethernet Port. SNMP Management In addition to the Web interface, you can also manage and configure a P-520 using the Simple Network Management Protocol (SNMP). SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth. In order to manage the device you have to provide your Network Management System software with adequate MIB files. Please consult your management software manuals on how to do that. P-520 Features IEEE 802.11g/b Access Point, Wi-Fi certified Integrated high-gain diversity antennas Adjustable output power, up to 20dBm Power-over-Ethernet support, IEE 802.3af compliant Theft protection system 802.1x/EAPoLAN WPA (PSK, TKIP) Seamless roaming (IAPP support) Virtual local area network support (VLAN) Remote management, remote updates Layer 2 Isolation (disable peer-to-peer traffic) ACL (Access Control List) DHCP client Remote software update SNMPv1, SNMPv2, incl. traps, MIB-II, IEEE-802.11, Gemtek general Private MIB Operating Modes The P-520 Access Point can work in different operating modes: Access Point (AP) mode: In AP mode the P-520 can connect multiple wireless client stations to a wired network. The Local Area Network and the Wireless Network are from the same IP address space. Gemtek Systems Page 10 User’s Guide Chapter 1 – Introduction Access Point with WDS (Wireless Bridge and Wireless Repeater) mode: A WDS (Wireless Distribution System) allows you to create a wireless network infrastructure. Normally, the access points must be connected with a wire (LAN), which is generally an Ethernet connection in business applications. Once connected, these access points create wireless cells allowing a wireless connection. The WDS feature allows the access points to be wirelessly connected to another access point, eliminating the need to the wired connection between them. Two WDS configurations are described in the following pictures: wireless bridge and wireless repeater. Gemtek Systems Page 11 User’s Guide Chapter 1 – Introduction Wireless Bridge: The first use of the WDS, Wireless Bridge mode is to create the wireless bridge between two or more wired networks, for example networks in different buildings with no wired connections between them. All APs in a WDS have to be configured for the same radio channel and must be configured with their WDS partner AP BSSIDs (MAC addresses). The data being transported is bridged transparently; i.e., the data received by the LAN station is identical to data that would be received if both LAN stations had been connected to the same LAN subnet. Gemtek Systems Page 12 User’s Guide Chapter 1 – Introduction Wireless Repeater: The other use of the WDS, Wireless Repeater mode is to extend wireless area coverage between wired and wireless networks. This mode is normally used in large, open areas, where pulling a wire is prohibited or not cost effective and in residential circumstances. By settings up the BSSIDs (MAC addresses) between AP’s WDS partners, stations can intersect with any AP of this BSSID and move between the coverage of both APs. In both cases, the P-520 acts as a network bridge between wireless and wired networks. All data received by the P-520 on its wireless or Ethernet interface is broadcast on the wireless interface to all connected devices that are authorized in the ACL (access control list). Antenna Diversity The P-520 Operator Access Point uses antenna diversity to select the best reception signal at the two integrated antennas. Antenna diversity counters the adverse effects of multi-path fading and antenna pattern nulls and reduces the packet error rate. The main antenna (at internal connector J4) is used for transmission whereas both antennas, main and aux, can receiving signals. Receive diversity examines only packets directed at the AP. A count of frames received consecutively with FCS errors is compared to the configured threshold value. When this value is reached, the receive antenna used is switched to the other antenna. If a directed frame is received without errors the error count is reset back to zero.

Gemtek Systems Page 36 User’s Guide Chapter 4 – Reference Manual Configuration Configuration | Configuration | Settings Summary The Settings Summary page shows important information of the P-520: its IP address, SSID, wireless security settings and access control status. The page is not configurable but displays the current system configuration only. Figure 21 – Settings Summary SSID – indicates the unique name for your wireless network. IP Address – indicates the IP address of your P-520. If two addresses are displayed this means that the access point retrieved its IP address dynamically via DHCP. The first IP address is the IGMP IP multicast address; the second IP is given from DHCP server’s pool. Wireless Security – indicates if security methods are enabled on your access point [None, WEP, WPA, 802.1X]. Access Control – indicates access control status [Any client/Selected clients only]. Configuration | Configuration | Identity The identity data of the access point are displayed here. You can use the first three fields Name, Location, Contact to describe the access point. These fields do not influence the behavior of the access point. But are for information purposes only. Gemtek Systems Page 37 User’s Guide Chapter 4 – Reference Manual Figure 22 – Identity Settings Name – specify the administrative name of the access point [string]. Location – specify the location where your device is installed [string]. Contact – specify the name of the person/company responsible for the P-520 [string]. MAC Address – displays the MAC address of the access point. Cannot be changed. Access Point Type – displays information on your type of access point. Cannot be changed. Firmware Version – displays the version number of the software that controls the access point. Boot Loader Version – displays the boot loader version. Cancel – restore all previous values. Apply – save changed configuration. Configuration | Local Area Network | Network Setup The IP configuration as described below is required for device management purposes. IP addresses can either be retrieved from a DHCP server or configured manually. Figure 23 – Network Setup Settings Gemtek Systems Page 38 User’s Guide Chapter 4 – Reference Manual IP Address – specify the access point’s IP address [digit and dots]. When shipped from the factory or reset to factory settings, the AP defaults to a static IP address of 192.168.2.2. Subnet Mask – specify the access point’s subnet mask [digit and dots]. When shipped from the factory or reset to factory settings, the AP defaults to a subnet mask of 255.255.255.0. Gateway – specify the IP address of the access point’s gateway [digit and dots]. When shipped from the factory or reset to factory settings, the AP defaults to a gateway IP address of 192.168.2.1. If you change the IP address manually, make sure that the chosen IP address is unused and belongs to the same IP subnet as your wired LAN, otherwise you will loose the connection to the P-520 from your current PC. If you enable the DHCP client via a Web browser, the browser will loose the connection after rebooting, because the IP address assigned by the DHCP server is not predictable. If Dynamic is selected the static IP settings are displayed but have no affect on the network configuration. The dynamic IP address and gateway address as assigned by the DHCP server are applied to the system after restart. To find your P-520 with dynamic IP settings use a utility such as Gemtek Systems KickStart. Configuration | Local Area Network | Virtual LAN A Virtual Local Area Network (VLAN) is a mechanism to segregate devices or groups of devices on the same physical LAN. P-520 allows the definition of a VLAN by a VLAN identifier. If you enable the VLAN functionality in the menu Configuration | Local Area Network | Virtual LAN all traffic from the wireless LAN to the LAN will be tagged with the specified VLAN ID. Incoming traffic from the wired LAN not tagged with the appropriate VLAN ID is discarded by the AP. Figure 24 – Virtual Local Area Network (VLAN) Settings To define a VLAN membership on the access point, select the checkbox and enter the VLAN identifier: Figure 25 – Enable Virtual Local Area Network (VLAN) VLAN id – specify the ID for your VLAN network [1 to 4094]. Wireless client devices connected to the AP are grouped into this VLAN. Cancel – restore all previous values. Gemtek Systems Page 39 User’s Guide Chapter 4 – Reference Manual Apply – save changed configuration. When VLAN is enabled you can view this interface statistic in Status | Interface Statistics page. There you can see such parameters as interface status, InOctets, InUcast, InMcast, OutOctets, OutUcast and OutMcast. Configuration | Wireless | Basic Settings Use the Configuration | Wireless | Basic Settings menu to configure the most relevant wireless settings of your access point. Figure 26 – Basic Wireless Settings Country – click on the select country… link and choose from drop-down list the country in which you will use the AP. According to the country chosen the regulatory domain settings change. You are not allowed to select radio channels and RF output power values other the permitted values for your country and regulatory domain. See also appendix B) Regulatory Domain/Channels. Regulatory Domain – displays the regulatory domain according selected country [ETSI/FCC]. Not configurable. IAPP – select this checkbox to enable seamless roaming of client stations between P-520 APs. By using the Inter-Access Point Protocol (IAPP) roaming, a client can be hand-over between access points when changing its physical location. The IAPP protocol is used to ensure all relevant session information is delivered to the new AP to which the client is moving. IAPP roaming is compatible with other Gemtek Systems products. Look at the scheme for more details about IAPP roaming: Gemtek Systems Page 40 User’s Guide Chapter 4 – Reference Manual RADIUS Server AP2 AP1 IAPP Roaming Client Figure 27 – IAPP Roaming Scheme The wireless client is switched from AP1 to AP2 when entering the coverage area of the new access point (AP2). The roaming is performed without client re-authentication. The IAPP protocol ensures to inform the old AP1 of the new client association. The AP1 then stops the client RADIUS session, and the AP2 starts the client’s session with the RADIUS. IAPP roaming requires that all access points share the same SSID. Wireless Network Name (SSID) – is a unique name for your wireless network [1-32 symbols]. The default SSID is "P520" but you should change this to a personal wireless network name. The SSID is important for client stations when connecting to the access point. All client stations must have their client SSID settings configured and must use the same SSID. Band – click on the change policy… link and choose the policy of internal radio mode [Mixed/Gonly/B-only]. Changing the radio policy could result in a loss of your connection when you are using a wireless connection. Radio Channel – select the channel that the access point uses to transmit and receive information. Multiple frequency channels are used to avoid interference between nearby access points. If you wish to operate more than one access point in overlapping coverage areas, we recommend a distance of at least four channels between the chosen channels. For example, for three access points in close proximity choose channels 1, 6 and 11. Before changing radio settings manually, verify that these settings comply with your national regulations. At all times, it is the responsibility of the end-user to ensure that the installation complies with local radio regulations. Refer to the appendix, B) Regulatory Domain/Channels for more details. Click on the autochannel… link and a pop-up window with auto channel settings will appear. You can now select a list of preferred channels: Gemtek Systems Page 41 User’s Guide Chapter 4 – Reference Manual Figure 28 – Auto Channel Settings The auto-channel function is a great technique to minimize interference between access points. With auto-channel selection enabled the P-520 will regularly scan the air for neighboring access points and selects the channel with the least expected interference. The range of scanned channels can be limited by the administrator. Do not use auto-channels when using WDS, otherwise the access points will not be able to communicate between each other wirelessly. PRISM Nitro – increases the performance in 802.11g and mixed-mode environments. The Nitro technology provides up to 50% more throughput in g-only networks; up to 300% more in mixed-mode (802.11b and 802.11g) networks by eliminating collisions and employing packet bursting technology. A maximum of 140Mbps throughput can be reached by selecting a packet burst lengths of 1500µs: Off – switch off PRISM Nitro, Minimum – burst length is 650 µs, Medium – burst length is 1000 µs, Maximum – burst length is 1500 µs; Broadcast SSID – when selected your AP’s SSID is visible during network scans on a wireless station. When unselected, the AP’s SSID is not visible and not broadcasted to wireless stations. Domain Max Output Power – indicates the maximal output power according selected regulatory domain. Cannot be modified. Antenna Gain – is the gain of the connected antenna in relation to an isotropic radiated power (dBi). Cannot be modified. Wireless Card Output Power – select the wireless card output power in dBm. Wireless card output power list will vary according selected regulatory domain. Total Output Power (EIRP) – is the maximum radiated output power of the antenna (strength of the radio signal transmitted). Cannot be modified. It is also referred to as the maximum EIRP (Effective Isotropic Radiated Power) value (dBm). The higher is the number, the stronger the signal is. Cancel – restore all previous values. Apply – save changed configuration. Gemtek Systems Page 42 User’s Guide Chapter 4 – Reference Manual Configuration | Wireless | WDS Links The access point P-520 supports the definition of a WDS (Wireless Distribution System). In WDS mode a P-520 can act as wireless bridge or wireless repeater. Choose the Configuration | Wireless | WDS Links menu if you want to setup bridge links between different access points while connecting wireless client stations in parallel. Up to seven access points can be interconnected in a wireless distribution system. In the WDS table bride links can be defined by selecting WDS ready access points by their MAC address. Make sure that the radio channel and the data rates for all WDS APs are set to the same values. APs that relay data received from a wireless station to another access points (and vice versa) have to receive and send each packet over the same channel. Hence the overall throughput will be reduced for each relay link. As an option WDS links to other APs can be added manually by specifying the MAC address of the remote AP. APs participating in a WDS network DO NOT have to be configured with the same SSID. Add AP in WDS from the WDS Links table: In the menu Configuration | Wireless | WDS Links you can find a table of remote access points that you can connect to via a WDS Link. On this table an administrator can see access points, their operating channels, data rates, RSSI (Received Signal Strength Indication) and the Age of the last signal. Select the checkbox to add an access point to the Wireless Distribution System. The checkboxes will be active only of those WDS links that uses the same channel as your device: Figure 29 – WDS Links for Internal Radio Table Enable – select if need to add the access point to Wireless Distribution System.

Gemtek Systems Page 46 User’s Guide Chapter 4 – Reference Manual Configuration | Wireless | Advanced Settings For normal operation the following default settings do not need to be modified. Changing the P-520 advanced settings requires expert knowledge of the 802.11 protocol and the radio functionality. The configuration menu Configuration | Wireless | Advanced Settings allows administrators to change low level radio parameters: Figure 32 – Advanced Wireless Settings Operational Rate Set – this setting specifies the set of Supported and Basic data rates at which the station may transmit data. Each rate shall be within the range from 2 to 127, corresponding to data rates in increments of 500 kb/s from 1 Mb/s to 63.5 Mb/s, and shall be supported for receiving data. This value is reported in transmitted Beacon, Probe Request, Probe Response, Association Request, Association Response, Reassociation Request, and Reassociation Response frames, and is used to determine whether a BSS with which the station desires to synchronize is suitable. Operational rate set is defined as hexadecimal string where highest bit of each digit represents if Supported rate is the Basic rate (basic rate = supported rate | 0x80, where “|” means “bitwise or” operation). Beacon Period – this setting specifies the amount of time between beacons in milliseconds. A beacon is a packet broadcast by the access point to synchronize the wireless network. RTS Threshold – this setting specifies the maximum packet size beyond which the Wireless LAN Card invokes its RTS/CTS mechanism. Packets that exceed the specified RTS threshold trigger the RTS/CTS mechanism. The NIC transmits packets smaller than this threshold without using RTS/CTS [[0-2347] default: 2347 (2347 means that RTS is disabled)]. Fragmentation Threshold – the fragmentation threshold, specified in bytes, determines whether packets will be fragmented and at what size. On an 802.11 wireless LAN, packets exceeding the fragmentation threshold are fragmented, i.e., split into, smaller units suitable for the circuit size. Packets smaller than the specified fragmentation threshold value are not fragmented [[256-2346] default: 2346 (2346 means that fragmentation is disabled)]. Cancel – to restore all previous values.

Gemtek Systems Page 65 User’s Guide Chapter 5 – SNMP Management Chapter 5 – SNMP Management Introduction Another way to configure and monitor the access point (P-520) via a TCP/IP network is SNMP (Simple Network Management Protocol). SNMP is an application layer protocol that facilitates the exchange of management information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth. The SNMP agent and management information base (MIB) reside on the access point. To configure SNMP on the AP, you define the relationship between the Network Management System (NMS) and the SNMP agent (our AP). The SNMP agent contains MIB and Gemtek Systems private MIB variables whose values the SNMP manager can request or change. A NMS can get a value from an agent or store a value into the agent. The agent gathers data from the MIB, the repository for information about device parameters and network data. The agent can also respond to a manager’s requests to get or set data. In order to manage the device you have to provide your Network Management System software with adequate MIB files. Please consult your management software manuals on how to do that. SNMP Versions The access point supports the following versions of SNMP: SNMPv1—The Simple Network Management Protocol: A Full Internet Standard, defined in RFC 1157. (RFC 1157 replaces the earlier versions that were published as RFC 1067 and RFC 1098.) Security is based on community strings. SNMPv2c—The community-string based Administrative Framework for SNMPv2. SNMPv2c (the "C" stands for "community") is an Experimental Internet Protocol defined in RFC 1901, RFC 1905, and RFC 1906. SNMPv2c is an update of the protocol operations and data types of SNMPv2p (SNMPv2 Classic), and uses the community-based security model of SNMPv1. Both SNMPv1 and SNMPv2c use a community-based form of security. The community of managers able to access the agent's MIB is defined by an IP address access control list and password. The Access Controller implementation of SNMP supports all MIB II variables (as described in RFC 1213) and defines all traps using the guidelines described in RFC 1215.The traps described in this RFC are: coldStart A coldStart trap signifies that the SNMP entity, acting in an agent role, is reinitializing itself and that its configuration may have been altered. WarmStart A WarmStart trap signifies that the SNMP entity, acting in an agent role, is reinitializing itself Gemtek Systems Page 66 User’s Guide Chapter 5 – SNMP Management and that its configuration is unaltered. authenticationFailure An authenticationFailure trap signifies that the SNMP entity, acting in an agent role, has received a protocol message that is not properly authenticated. linkDown A linkDown trap signifies that the SNMP entity, acting in an agent role, recognizes a failure in one of the communication links represented in the agent's configuration. linkUp A linkUp trap signifies that the SNMP entity, acting in an agent role, recognizes that one of the communication links represented in the agent's configuration has come up. SNMP Agent The SNMP agent is integrated in your P-520 and responds to SNMP manager requests as follows: Get a MIB variable—The SNMP agent begins this function in response to a request from the SNMP manager. The agent retrieves the value of the requested MIB variable and responds to the manager with that value. Set a MIB variable—The SNMP agent begins this function in response to a message from the SNMP manager. The SNMP agent changes the value of the MIB variable to the value requested by the manager. The SNMP agent also sends unsolicited trap messages to notify an SNMP manager that a significant event has occurred (e.g. authentication failures) on the agent. SNMP Community Strings SNMP community strings authenticate access to MIB objects and function as embedded passwords. In order for the SNMP manager to access the controller, the community string must match one of the two community string definitions on the controller. A community string can be as follows: Read-only – gives read access to authorized management stations to all objects in the MIB except the community strings, but does not allow write access. Read-write – gives read and write access to authorized management stations to all objects in the MIB, but does not allow access to the community strings. The SNMP Read-write community string is also the administrator’s password. If the password is changed the SNMP community string will be changed as well. Use SNMP to Access MIB As shown in the picture Figure 63 – SNMP Network SNMP agent gathers data from the MIB. The agent can send traps (notification of certain events) to the SNMP manager, which receives and processes the traps. Traps are messages alerting the SNMP manager to a condition on the network such as improper user authentication, restarts, link status (up or down), MAC address tracking, and so forth. The SNMP agent also responds to MIB-related queries sent by the SNMP manager in getrequest, get-next-request, and set-request format. Gemtek Systems Page 67 User’s Guide Chapter 5 – SNMP Management P-520 get-request, get-next-reguest, get-bulk, set-request get-response, traps MIB SNMP Agent SNMP Manager Figure 63 – SNMP Network Gemtek Systems Private MIB In addition to standard SNMP MIBs the P-520 supports the private Gemtek Stystems MIB. The private MIBs are enterprise specific and serve to extend the functionality of the standard MIBs. Private MIB identifies manageable objects and their properties that are specific to the managed device. MIBs let you manage device not only by using WEB or Command Line Interface but also using SNMP protocol. The descriptions and brief explanations of managed objects are available in the MIB file. The MIB file is a specially formatted text file. It is using the so-called ASN.1 standard syntax.

It uses a variation of High Speed Data Link Control (HDLC) for packet encapsulation. network address The network portion of an IP address. For a class A network, the network address is the first byte of the IP address. For a class B network, the network address is the first two bytes of the IP address. For a class C network, the network address is the first three bytes of the IP address. In each case, the remainder is the host address. In the Internet, assigned network addresses are globally unique. See IP address. for communication between two computers using a serial interface, typically a personal computer connected by phone line to a server. PPP uses the Internet protocol (IP) (and is designed to handle others). It is sometimes considered a member of the TCP/IP suite of protocols. Relative to the Open Systems Interconnection (OSI) reference model, PPP provides layer 2 (data-link layer) service. Essentially, it packages your computer's TCP/IP packets and forwards them to the server where they can actually be put on the Internet. PPP is usually preferred over the earlier de facto standard Serial Line Internet Protocol (SLIP) because it can handle synchronous as well as asynchronous communication. PPP can share a line with other users and it has error detection that SLIP lacks. Where a choice is possible, PPP is preferred. node An addressable device attached to a computer network. See host, router. Gemtek Systems Page 80 User’s Guide Glossary PPPoE: PPPoE (Point-to-Point Protocol over protocol A formal description of message Ethernet) is a specification for connecting multiple computer users on an Ethernet local area network to a remote site through common customer premises equipment, which is the telephone company's term for a modem and similar devices. PPPoE can be used to have an office or building-full of users share a common Digital Subscriber Line (DSL), cable modem, or wireless connection to the Internet. PPPoE combines the Point-to-Point Protocol (PPP), commonly used in dialup connections, with the Ethernet protocol, which supports multiple users in a local area network. The PPP protocol information is encapsulated within an Ethernet frame. formats and the rules two computers must follow to exchange those messages. Protocols can describe low-level details of machine-tomachine interfaces (e.g., the order in which bits and bytes are sent across a wire) or highlevel exchanges between allocation programs (e.g., the way in which two programs transfer a file across the Internet). PPPoE has the advantage that neither the telephone company nor the Internet service provider (ISP) needs to provide any special support. Unlike dialup connections, DSL and cable modem connections are "always on." Since a number of different users are sharing the same physical connection to the remote service provider, a way is needed to keep track of which user traffic should go to and which user should be billed. PPPoE provides for each user-remote site session to learn each other's network addresses (during an initial exchange called "discovery"). Once a session is established between an individual user and the remote site (for example, an Internet service provider), the session can be monitored for billing purposes. PPTP: Point-to-Point Tunneling Protocol QOS Quality of Service. Transmission system qualities measure in terms of reliability and availability. RADIUS (Remote Authentication Dial-In User Service) is a client/server protocol and software that enables remote access servers to communicate with a central server to authenticate dial-in users and authorize their access to the requested system or service. RADIUS allows a company to maintain user profiles in a central database that all remote servers can share. It provides better security, allowing a company to set up a policy that can be applied at a single administered network point. Having a central service also means that it's easier to track usage for billing and for keeping network statistics. route The path that network traffic takes from the source to the destination. It may include many gateways, routers, hosts and physical networks. (PPTP) is a protocol (set of communication rules) that allows corporations to extend their own corporate network through private "tunnels" over the public Internet. Effectively, a corporation uses a wide-area network as a single large local area network. This kind of interconnection is known as a virtual private network (VPN). route table A table listing information about routes to other hosts or networks, such as the remote network or host address, the interface down which the route exists, the distance to the remote address and the cost of sending data over the route. port The abstraction used by Internet transport router A system responsible for making protocols to distinguish among multiple simultaneous connections to a single destination host. A port is a transport layer demultiplexing value. Each application has a unique port number associated with it. It is also used to refer to one of the physical network connectors on the router. Gemtek Systems decisions about which of several paths network (or Internet) traffic will follow. To do this it uses a routing protocol to gain information about the network, and algorithms to choose the best route based on several criteria known as “routing metrics”. Page 81 User’s Guide Router On the Internet, a router is a device or, in some cases, software in a computer, that determines the next network point to which a packet should be forwarded toward its destination. The router is connected to at least two networks and decides which way to send each information packet based on its current understanding of the state of the networks it is connected to. server A network device that provides services to client stations. Examples include file servers and print servers. service A term used with the router to refer to a Glossary topology A network topology shows the computers and the links between them. A network layer must know the current network topology to be able to route packets to their final destination. UDP User Datagram Protocol. A transport layer protocol in the TCP/IP suite of protocols. UDP, like TCP, uses IP for delivery; however, unlike TCP, UDP provides for exchange of datagrams without acknowledgements or guaranteed delivery. Protocol. The Internet standard protocol developed to manage nodes on an IP network. See MIB. URL Uniform Resource Locator. A standard format for specifying the name, type and location of documents and resources on an Internet. The syntax is type://host.domain :port/path/filename, where type specifies the type of document or resource (e.g. http is a file on a WWW server; file is a file on an anonymous FTP server; Telnet is a connection to a Telnet-based service). See WWW. subnet A portion of a network, which may be a connection to another port on (another) router, used to access dialup modems, hosts that do not support TCP/IP and other asynchronous devices. SNMP A Simple Network Management physically independent network segment, which shares a network address with other portions of the network and is distinguished by a subnet number. A subnet is to a network what a network is to an internet. subnet address The subnet portion of an IP address. In a subnetted network, the host portion of an IP address is split into a subnet portion and a host portion using an address or subnet mask. See subnet mask, IP address and network address. subnet mask A bit mask used to select bits from an Internet address for subnet addressing. The mask is 32 bits long and selects the network portion of the Internet address and one or more bits of the local portion. Sometimes called address mask. TCP Transmission Control Protocol. The TCP/IP standard transport layer protocol in the Internet suite of protocols, providing reliable, connection-oriented, full-duplex streams. It uses IP for delivery. WAN Wide Area Network. Any physical network technology that spans large geographic distances. WANs usually operate a slower speeds than LANs. See LAN. Wi-Fi is short for wireless fidelity and is another name for IEEE 802.11b. It is a registered trademark of Wi-Fi Alliance. "Wi-Fi" is used in place of 802.11b in the same way that "Ethernet" is used in place of IEEE 802.3. Products certified as Wi-Fi by Wi-Fi Alliance are interoperable with each other even if they are from different manufacturers. A user with a Wi-Fi product can use any brand of access point with any other brand of client hardware that is built to the Wi-Fi standard. WWW World Wide Web. A hypertext-based, distributed information system based on client - server architecture. Web browsers (client applications) request documents from Web servers. Documents may contain text, graphics and audiovisual data, as well as links to other documents and services. Web servers and documents are identified by URLs (Uniform Resource Locators). See URL. Telnet The virtual terminal protocol in the TCP/IP suite of protocols, which allows users of one host to log into a remote host and interact as normal terminal users of that host.
