4 StreetWAVE™ Features

This chapter explains the salient features of the StreetWAVE™ roadside equipment.

Following is the architecture diagram of StreetWAVE™. Each component is explained briefly in

the following sub-sections:

StreetWAVE™ features are explained briefly in the following sub-sections:

4.1 DSRC Radio Pair

Each StreetWAVE™ unit consists of two (2) integrated high power DSRC radios, which are

exposed as the following two interfaces:

 Radio 1

 Radio 2

StreetWAVE™ radio configuration is very flexible. Any or both radios can be configured on any

of the following channel modes:

 Alternating Channel Access

 Continuous Channel Access

The following applications can be configured to use any of the two interfaces (Radio1 or

Radio2):

 Immediate Forward

 Store and Repeat

 IPv6-provider

 DSRC Message Forward

 TCD

Figure 1: StreetWAVE Software Architecture Diagram

RSU2 User Guide

Savari Inc., Confidential

 RTCM

 NTP

However, radio configuration between the above-mentioned applications should be consistent.

You can operate multiple StreetWAVE™ units in a hub-and-spoke configuration in which the

hub unit originates a message. It broadcasts those messages on its configured DSRC interface

to OBUs as well as on Ethernet interface to the spoke StreetWAVE™ units in Savari ’s

proprietary format. The spoke StreetWAVE™ units receive them and broadcast them on their

DSRC interfaces, essentially working as DSRC repeaters. This configuration is useful at an

intersection where no specific location has line of sight to all approaches to the intersection.

The Hub unit does not have to be in the traffic controller cabinet. It can be one of the units on

the pole if it has Ethernet connectivity to the cabinet.

4.2 IPv4 and IPv6 Networking

Each StreetWAVE™ unit consists of one Ethernet interface (eth0). StreetWAVE™ provides

support for both IPv4 and IPv6 networking on all its interfaces (eth0, Radio 1, or Radio 2).

You can enable the following on all the three available interfaces:

 IPv4 and IPv6 addresses

 IPv6 Router Advertisements

StreetWAVE™ can forward both IPv4 and IPv6 packets between its interfaces (Ethernet and

DSRC) acting as a router. It also supports both IPv4 and IPv6 firewalls allowing the following:

 Source and destination IPv4 or IPv6 addresses

 Port-based rules

4.3 Immediate Forward

StreetWAVE™ Immediate Forward application supports the forwarding feature in addition to the

following features.

UDP Listener

4.3.1

StreetWAVE™ Immediate Forward application listens on configured UDP ports. If any message

is received on these ports in the format specified in USDOT RSE requirements, it will sign the

message using the 1609.2 protocol, if specified in the incoming message, and immediately

transmits on the configured DSRC interface with the PSID and channel specified in the

incoming message. Incoming messages could specify different priorities but it must specify the

same transmit mode (TxMode) and transmit channel (TxChannel). This feature is used when an

RSU2 User Guide

Savari Inc., Confidential

intermediate device (TCID or a Battelle device) is sending periodic Immediate Forward

messages to a StreetWAVE™.

UDP Streaming

4.3.2

The StreetWAVE™ can be configured to receive data from other StreetWAVE™ and stream it

over DSRC. This allows the StreetWAVE™ to function as a repeater. In this setup, one

StreetWAVE™ is configured as the Hub unit and all other StreetWAVE™ that are connected to

it as Spoke units (that are not capable of independently transmitting Store and Repeat,

Immediate Forward etc. and are depending on the Hub to provide this data). The Hub transmits

the data over the air as well as to the Spoke unit typically over an Ethernet link. The Spoke unit,

upon reception of the Hub’s packet, decodes and applies rules that are present in the packet,

signs (if it is present in the packet) and forwards the packet over DSRC. The ability of the

StreetWAVE™ to function in this manner can be used for streaming the packet data (in Savari

proprietary format) from TMCs or back-end servers over the air. This arrangement could be

useful in scenarios where a single StreetWAVE™ may not provide ample coverage for the

geographic area of interest.

4.4 Store and Repeat

StreetWAVE™ supports transmission of Store and Repeat. The Store and Repeat application,

which runs on the StreetWAVE™ unit, transmits on the configured channel over the Radio 1

(default configuration) interface.

Store and Repeat are configured in a data store inside the StreetWAVE™. The data store

supports up to 100 Store and Repeat. The Store and Repeat are stored in the form of Active

message files. Each file contains the transmissions parameters and the actual data of the Store

and Repeat message. Each Store and Repeat message can be scheduled differently. The

active message files follow the USDOT RSE 4.1 Specification.

Active Store and

Repeat Message Configuration

4.4.1

StreetWAVE™ supports the USDOT Active Message Configuration file format for configuring

active Store and Repeat messages.

US DOT Active Message Configuration file format

This format is defined in section US DOT RSU 4.1 requirements. Each Store and Repeat

active message should be defined in a separate file.

RSU2 User Guide

Savari Inc., Confidential

4.5 1609.3 IPv6 Provider

StreetWAVE™ supports WSAs as per the 1609.3 protocol. If enabled, StreetWAVE™ switches

channels on the configured interface between the following:

 178 (control channel)

 Configured service channel.

StreetWAVE™ runs IPv6 traffic on a service channel in the configured service channel interval.

Such IPv6 traffic is transparent to StreetWAVE™. It merely routes IPv6 traffic from/to DSRC

interface from the Ethernet interface.

StreetWAVE™ announces this service availability using WSAs including Service Info and WRA

elements. The Service Info element consists of PSID, channel information, and the service

channel. WRAs consist of router IPv6 prefix, gateway address, and DNS addresses so that

OBEs can configure their IPv6 addresses, default gateway, and DNS servers.

4.6 1609.2 Security

StreetWAVE™ supports 1609.2 Draft 9.3 security protocol. It supports signed Immediate

Forward, and Store and Repeat messages and signed WSAs to announce IPv6 services. The

security feature can be individually enabled or disabled on Immediate Forward, Store and

Repeat, and IPv6 applications.

StreetWAVE™ ships with the following pre-generated certificates supplied by US DOT:

 One root certificate

 Five different message signing certificates

 One WSA signing certificate

The following security profile is used for signing Immediate Forward, and Store and Repeat

messages:

4.7 Interface Logging

StreetWAVE™ supports logging all DSRC and IP messages transmitted and received in the

PCAP format to the persistent memory. All packet activity on all interfaces are captured and

logged in the PCAP format. The PCAP files can then be seen in Wireshark after file offload has

transferred the PCAP files to a back-office server. In addition, the system-status log messages

are logged to separate files. There is ~3GB of space set aside for this total logging.

A packet from an OBE can be received and logged potentially by all StreetWAVE™ units at an

intersection. This independent logging feature provides the ability to analyze which unit is

capable of hearing from which approach and from how far. However, it may require analysis of

logs from multiple StreetWAVE™ units to track a single vehicle. Such an analysis can be

performed using post-processing tools and is not the main function of StreetWAVE™. Hence,

this independent logging trade-off is chosen over the complexity of integrated logging.

4.8 DSRC Message Forward

StreetWAVE™ supports the DSRC Message Forward feature as outlined in USDOT RSU 4.1

specification. This application provides the capability to forward any DSRC message received

over the air to an external server over an ethernet link. The specification USDOT RSU 4.1 lists

certain filter criteria that must be met for the messages to be forwarded. The DSRC Message

Forward feature transparently forwards all messages if the filter criterion is successful. The

application does not terminate the packet with regards to security or content.

6 Using the Command Line Interface (CLI)

6.1 Log File Handling

The following are the log file handling functions of StreetWAVE™:

Interface Logs

6.1.1

This is a repository for all the packets received and transmitted from all interface radio 1, radio

2 and Ethernet.

The StreetWAVE™ starts deleting the oldest log files (Interface log and Systemlogs) once the

directory occupancy is 80% of the disk capacity.

Tx/Rx Packet Log File Name Format

6.1.2

TX/RX Packet log file names are in the following format:

<fileprefix>_<interface>_<out/in>_YYYY_MM_DD_HH_MM_SS.pcap, where

<fileprefix> is configured prefix

<interface> is eth/dsrc0/dsrc1

<out/in> is out for outgoing packets and in for incoming packets

YYYY_MM_DD_HH_MM_SS is the timestamp in UTC when the file was opened.

For example:

root@StreetWAVE:/nojournal/pcaplogs# pwd

/nojournal/pcaplogs

root@StreetWAVE:/nojournal/pcaplogs# ls -l

-rw-r--r-- 1 root root 42808 Jul 20 00:47

StreetWAVE_eth_out_2011_07_20_00_47_26.pcap

-rw-r--r-- 1 root root 1594308 Jul 20 01:01

StreetWAVE_dsrc0_in_2011_07_20_00_47_55.pcap

root@StreetWAVE:/nojournal/pcaplogs#

Retrieving the PCAP Files

6.1.3

The .pcap files can be retrieved only from StreetWAVE™ to any external device through SCP.

NOTE: Please use manual log file transfer when the system is in “standby” mode.

RSU2 User Guide

Savari Inc., Confidential

Deleting the PCAP Files

6.1.4

Once pcap files are copied out of StreetWAVE™, it is advisable to delete them from

StreetWAVE™. This helps to conserve disk space on the StreetWAVE™ for further TX Packet

logging.

6.2 Network configuration

This is used to configure the IP addresses subnet and gateway for Ethernet and Radio1 and

Radio2

IP Address configuration

6.2.1

When a IP address (ipv4/ipv6) is configured / reconfigured for an interface, corresponding

gateway or gateway length should also be updated before committing the change.

6.3 Firewall configuration

Firewall configuration requires separate rules for IPv4 and IPv6. Configuration files are

separate for IPv4 and IPv6, but the format is same.

6.4 Immediate Forward

StreetWAVE™ Immediate Forward application requires the following two configurations:

 The main configuration file containing the UDP configuration.

 Incoming stream of messages as specified in US DOT RSE requirements

UDP streaming configuration is not needed if only one StreetWAVE™ unit is used at a given

intersection.

6.5 Store and Repeat

StreetWAVE™ Store and Repeat application requires the following two configurations:

 The main Configuration file contains ActiveDB path and UDP configuration.

RSU2 User Guide

Savari Inc., Confidential

 Store and Repeat active message configuration contains message scheduling

parameters and message contents. (As per USDOT Req 4.1)

6.6 Sample Safety Pilot Deployment configuration

StreetWAVE™ radio configuration is very flexible. Any or both radios can be configured on any

channel in channel switching or continuous mode. Any sub-system (Store and Repeat,

Immediate Forward, and IPv6 provider) can be configured to use any of the two interfaces.

However, channel mode, channel numbers, and DSRC radios between all sub-systems should

be consistent on a given StreetWAVE™ unit.

The following is the recommended configuration:

 Store and Repeat and IPv6 run on Radio 1, channel-switching mode between control

channel 178 and any service channel (except 172/178). Store and Repeat transmits on

configured channel (182 default) in ActiveDB files and IPv6 runs on control channel.

 Immediate Forward, Immediate Forward, applications run on service channel 182 on

Radio 2, which is in continuous channel mode.

One of the StreetWAVE™ units can be configured as a UDP streaming unit. This is called Hub

StreetWAVE™. Other StreetWAVE™ units can be configured as stream receivers and are

called spoke StreetWAVE™. However, if antennas are disconnected, these messages will not

reach OBEs. The Hub unit can also be one of the units on the pole. In either case, it requires

Ethernet connectivity to the cabinet. All spoke units also should have Ethernet connectivity to

the cabinet.

A sample safety pilot multi-unit deployment configuration is illustrated in Error! Reference

source not found. with salient configuration parameters. Only important parameters are shown

below for illustration. Those parameters that are not shown here should be left at defaults for

this configuration.

This chapter contains procedure to upgrade firmware.

Use the following procedure to upgrade (5.x to 5.x) the STREETWAVE™ firmware using the

CLI:

1. Connect a local PC to the STREETWAVE™ via Ethernet.

2. After connecting the Ethernet to STREETWAVE™, assign the IP address to the PC, in

the same subnet of the STREETWAVE™.

3. Download the image to be upgraded from the Savari FTP site to the PC.

4. Login to the STREETWAVE™ from the PC using SSH with the following credentials:

Password: 1[8V:2<J5*W;2I16H1nu

5. Copy the firmware image using the CLI command

utils copy remote_username:scp://ipaddr:path/to/file.image image:file.image

6. After copying the file using the above command, verify the same using the below

command.

utils list rsu-image

7. Execute one of the following commands:

utils rsu-upgrade -c < Firmware image name >

Also, all configurations (including, network, and wireless) will be lost, and they may need

to be configured again.

utils rsu-upgrade -n < Firmware image name >

(Where <Firmware image name> is the name of the firmware image that was copied in

the /tmp folder.)
