For details about voice features, see Feature Description - Voice.3.2.2 WANWAN uses the interfaces such as Ethernet, E1, T1, ADSL, VDSL, G.SHDSL, CPOS, 3G, andsynchronous/asynchronous serial interfaces. The physical links on these interfaces can run theFR, PPP, and HDLC protocols.Frame RelayWorking at the data link layer of the Open System Interconnection (OSI) model, Frame Relay(FR) uses simple methods to transmit and exchange data. On a frame relay (FR) network, virtualcircuits connect two FR devices. A physical line on the FR network provides multiple VCs. AVC defines an FR channel by using the data link connection identifier (DLCI), and detects andmaintains the VC status by using the local management interface (LMI).Multilink frame relay (MFR) is a cost-effective solution provided for FR users. MFR (FRF.16)implements the multilink frame relay function on the user-to-network interfaces (UNIs).The FR compression technologies compress FR packets to save network bandwidth, reducenetwork load, and improve data forwarding on the FR network. The AR supports FRF.9 (FRF.9 stac) and FRF.20 (FRF.20 IPHC).PPPThe point-to-point protocol (PPP) is used at the data link layer of the OSI model as well as atthe link layer of TCP/IP. PPP transmits data from one point to another through synchronouslinks and asynchronous links that support full duplex.Huawei AR G3 Series Enterprise RoutersProduct Description 3 Product CharacteristicsIssue 02 (2012-04-20) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.23
PPP provides a complete authentication mechanism. To set up a PPP connection, users mustpass authentication, ensuring a secured connection.Multilink PPP (MP) is a technique that bundles multiple PPP links together to increasebandwidth. It can be applied to the interfaces that support PPP, such as serial interfaces and low-speed Packet over SDH (POS) interfaces.PPPoEA Point-to-Point Protocol over Ethernet (PPPoE) network consists of an Ethernet containingmany hosts. It accesses the Internet through a remote access device.An AR can create a PPP session with the remote end by using PPPoE, and implement accesscontrol and accounting.An AR can function as the PPPoE server to connect to different types of PPPoE clients on theEthernet or function as a dial-up PPPoE client.ATMATM is connection-oriented. Each VC is identified by a Virtual Path Identifier (VPI) and aVirtual Channel Identifier (VCI). One pair of VPI/VCI values is useful only on a link segmentbetween ATM nodes. If a connection is broken, the relevant VPI/VCI values are released.The Asymmetric Digital Subscriber Line (ADSL) , VDSL and G.Single-pair High Speed DigitalSubscriber Line (G.SHDSL) interfaces of the ARs support the Asynchronous Transfer Mode(ATM).HDLCThe High-level Data Link Control (HDLC) is a typical bit-oriented synchronization data controlprotocol. It adopts the full-duplex mode and CRC check. Its transmission control function isindependent of the processing function, and it features control capabilities and can be flexiblyused.In HDLC, Keepalive packets are used to detect the link status. On the AR, you can set the intervalfor sending Keepalive packets by setting the polling interval.ISDNThe ISDN protocol references the Open Systems Interconnection (OSI) model and implementsfunctions of the physical layer, data link layer, and network layer on UNI interfaces.ISDN physical interfaces are classified into ISDN BRI and ISDN PRI interfaces.When the ARaccesses an ISDN network by using an ISDN PRI interface, the AR is directly connected to anISDN network-side device. When the AR accesses an ISDN network by using an ISDN BRIinterface, the AR connects to an NT1 device, and the NT1 device connects to an ISDN network-side device.For details about WAN features, see Feature Description - WAN.3.2.3 VPNThe ARs provide an IP security (IPSec) mechanism to ensure high quality, interoperable, andcryptology-based security for communication processes. The two parties in communication canHuawei AR G3 Series Enterprise RoutersProduct Description 3 Product CharacteristicsIssue 02 (2012-04-20) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.24
encrypt data and authenticate the data source at the IP layer to ensure the confidentiality andintegrity of the data and prevent replay on the network.IPSec implements these functions by using two security protocols: Authentication Header (AH)protocol and Encapsulating Security Payload (ESP). Internet Key Exchange (IKE) provides theautomatic key negotiation, SA establishment, and SA maintenance functions to simplify IPSecuse and management.The AR supports IPSec VPN and provides high reliability transmission tunnels for users. Inaddition, the AR uses Generic Routing Encapsulation (GRE) and Layer 2 Tunneling Protocol(L2TP) to support the following VPN services:lGRE VPNlIPSec VPNlBGP/MPLS IP VPNlSSL VPNlL2TP VPNlDSVPNlGRE over IPSec VPNlL2TP VPN over IPSec VPNFor details about VPN features, see Feature Description - VPN.3.2.4 SecurityACLAn access control list (ACL) defines a series of filtering rules based on certain policy, the ACLpermits or forbids the passage of data packets.The ARs can use ACL rules to filter packets.FirewalllACL-based packet filteringACL-based packet filtering is used to analyze the information of the packets to beforwarded, including source/destination IP addresses, source/destination port numbers, andIP protocol numbers. The ARs compare the packet information with the ACL rules anddetermine whether to forward or discard the packets.In addition, the ARs can filter the fragmented IP packets to prevent the non-initial fragmentattack.lASPFApplication Specific Packet Filter (ASPF) filters packets of the application layer based onpacket status. ASPF, used for security policies, detects the session information of theapplication layer protocol packets, which attempt to pass the AR and prevent the unsatisfiedpackets.lAttack defenseWith the attack defense feature, the ARs can detect various network attacks and protect theinternal network against attacks.Network attacks are classified into three types: DoS attacks, scanning and snooping attacks,and malformed packet attacks.Huawei AR G3 Series Enterprise RoutersProduct Description 3 Product CharacteristicsIssue 02 (2012-04-20) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.25
–DoS attackThe DoS attack is an attack to a system by using a large number of data packets. Thisprevents the system from receiving requests from authorized users or suspends the host.DoS attacks include SYN Flood attacks and Fraggle attacks. DoS attacks are differentfrom other attacks because DoS attackers do not search for the ingress of a network, butprevent authorized users from accessing resources or routers.–Scanning and snooping attackThe scanning and snooping attack is to identify the existing systems on a network byusing ping scanning (including ICMP and TCP scanning), and then find out potentialtargets. By using TCP scanning, attackers can identify the operating system and themonitored services. By scanning and snooping, an attacker can know the service typeand security vulnerability of the system and prepare for further intrusion to the system.–Malformed packet attackThe malformed packet attack is to send malformed packets to the system. If such anattack occurs, the system breaks down when processing the malformed IP packets.Malformed packet attacks include Ping of Death and Teardrop.ARP SecurityThere are various ARP attacks on networks, including attacks targeting hosts and gateways,address spoofing attacks and violent attacks, virus attacks, and malicious software attacks.The ARs ensure ARP security by discarding untrusted ARP packets, suppressing ARP packetsby using timestamps, discarding invalid ARP packets, and performing dynamic CAR on thepackets sent to the CPU. In addition to preventing ARP protocol attacks, the ARs also preventARP-based network scanning attacks.IP Source GuardSome attacks on networks aim at source IP addresses by accessing and using network resourcesthrough spoofing IP addresses, stealing users' information or blocking authorized users fromaccessing networks.lThe AR2200 and AR3200 series routers support IP source guard. IPSG prevents sourceaddress spoof attacks, so attackers cannot access network resources and authorized users'rights are protected.lUnicast Reverse Path Forwarding (URPF) blocks packets sent from bogus sourceaddresses.Local Attack DefenseThe Internet technology and size develop quickly and various network applications emerge.Many enterprises try to boost their own development by using their networks. They areconcerned about how to protect confidential data and resources in an open network environment.Some unconscious operations may attack network devices and degrade device performance oreven cause device failure.A large number of packets including valid packets and malicious attack packets on a networkmust be processed by devices' CPUs. The malicious attack packets affect services and may evencause a system breakdown. In addition, excessive normal packets can also lead to high CPUusage, which degrades the CPUs' performance and interrupts services. Therefore, protecting theCPU is a necessary and important factor for processing services and system response.Huawei AR G3 Series Enterprise RoutersProduct Description 3 Product CharacteristicsIssue 02 (2012-04-20) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.26
The local attack defense and source tracing functions protect the ARs against attacks. When anattack occurs, these functions ensure non-stop service transmission and minimize the impact ofthe attack on network services.PKIThe public key infrastructure (PKI) is a system that generates public keys and digital certificates,and verifies identities of certificate subjects to ensure information security. PKI issues digitalcertificates that bind public keys to respective user identities by means of a certificate authority(CA).AAAThe ARs support Authentication, Authorization, and Accounting (AAA).lAuthenticationVerifies users' identities.lAuthorizationGrants different rights for different users to restrict the services that can be used by users.lAccountingRecords information about network service usage of users, including service type, starttime, and traffic volume.For details about security features, see Feature Description - Security.3.2.5 QoSTraffic PolicingTraffic policing discards excess traffic to limit the traffic within a specified range and to protectnetwork resources as well as the carriers' interests.The ARs use committed access rate (CAR) to perform traffic policing. They support dual-rate-three-color markers and precise bandwidth management.Traffic ShapingWhen the rate of an interface on a downstream device is slower than that of an interface on anupstream device or burst traffic occurs, traffic congestion may occur on the downstream deviceinterface. Traffic shaping can be configured on the interface of an upstream device so thatoutgoing traffic is sent at even rates and congestion is avoided.The AR supportstraffic shaping adaptation and level-3 traffic shaping. Three-level shapersinclude the flow queue shaper, subscriber queue shaper, and port queue shaper.Congestion ManagementIf a network transmitting both delay-sensitive and delay-insensitive services is congestedintermittently, congestion management is required. However, if a network is always congested,bandwidth needs to be increased. Congestion management sends packet flows by using queuingand scheduling.An interface on AR has four or eight default queues for outgoing packets. A fixed FE interfaceon AR1220 has four default queues and each of other interfaces has eight. LAN-side interfacesHuawei AR G3 Series Enterprise RoutersProduct Description 3 Product CharacteristicsIssue 02 (2012-04-20) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.27
support the scheduling modes of priority queuing (PQ), deficit round robin (DRR), weightedround robin (WRR), PQ+DRR, and PQ+WRR. The AR150&200&1200 series routers do notsupport the DRR mode. WAN-side interfaces support the scheduling modes of PQ, WFQ, PQ+WFQ, and class-based WFQ (CBQ). Each scheduling algorithm schedules specific types oftraffic, and affects bandwidth allocation, delay, and jitter.Congestion AvoidanceCongestion avoidance is a flow control mechanism. A system configured with congestionavoidance monitors network resource usage such as queues and memory buffers. Whencongestion occurs or aggravates, the system discards packets.The ARs support tail drop and WRED.lTail dropWhen the queue length reaches the upper limit, the excess packets (buffered at the queuetail) are discarded.lWREDWRED sets the upper and lower drop thresholds and the maximum drop probability foreach queue. When the queue length is smaller than the lower threshold, no packets arediscarded. When the length of the queue exceeds the upper threshold, all packets arediscarded. When the queue length is between the lower threshold and the upper threshold,incoming packets are discarded randomly. The drop probability cannot be greater than themaximum drop probability.The ARs use the WRED based on queue profiles or traffic policies.For details about QoS features, see Feature Description - QoS.3.2.6 WLANNOTEOnly AR1220W and AR1220VW support WLAN.A wireless local area network (WLAN) connects two or more computers or devices and enablesthe devices to communicate by using the wireless telecommunication technology. WLAN usesthe wireless technology to implement fast Ethernet access. The primary advantage of WLAN isthat terminals, such as computers, can access a network through a wireless medium rather thana physical cable. This facilitates network construction and allows users to move around withoutinterrupting communication. WLAN is more flexible than traditional wired access.WLAN is widely used in public areas such as on campuses, business centers, and airports. TheWLAN uses cables at the backbone layer, and users access the WLAN through one or morewireless access points (WAPs) using radio waves. The transmission distance of a WAP is tensof meters.IEEE 802.11 is widely used by WLANs. The AR functions as fat APs to provide the followingWLAN functions:lWLAN user management–Dot1X access authentication–MAC address authentication–Pre-share-key (PSK) authentication–EAPOL-Key negotiationHuawei AR G3 Series Enterprise RoutersProduct Description 3 Product CharacteristicsIssue 02 (2012-04-20) Huawei Proprietary and ConfidentialCopyright © Huawei Technologies Co., Ltd.28

6.1 Various Maintenance MethodsThe ARs support various local and remote maintenance methods:lLocal maintenance using the console interfacelLocal or remote maintenance using TelnetlSecure shell (SSH) maintenance: guarantees security and provides authentication for loginusers on an insecure network, and defends against various attacks, including IP addressspoofing, plain text password interception, and denial of service (DoS).6.1.1 Web-based Network Management SystemThe ARs support the web-based network management system, which provides GUI for deviceconfiguration and management.Users can use the web-based system to manage network devices on the GUI. A junior engineercan use the GUI easily.6.1.2 CWMPThe CPE WAN Management Protocol (CWMP) is drafted by the Digital Subscriber's Line (DSL)forum. It is also called TR-069 standard. CWMP standardizes the communication betweencustomer premises equipment (CPE) and auto-configuration server (ACS).There are a lot of user devices separated on the access network. They are difficult to manageand maintain. The ARs are the CPE deployed at the user network side. The ACS uses CWMPto remotely manage the CPE. This reduces maintenance cost and improves troubleshootingefficiency.6.1.3 Remote Deployment and Maintenance Using USBAs the network expands, more and more network devices are used and software commissioningcosts increase. USB-based deployment does not require software commissioning, which reducesdeployment costs.Before using a USB flash drive to configure an AR, store software package and configurationfiles on the USB flash drive. Software engineers do not need to commission devices onsite. Afterinstalling the AR, hardware engineers will insert the USB flash drive into the USB interface onthe AR and power on the AR.
