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.

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.
