`
`host’s queue waiting for the first unicast message to be delivered to its
`destination.
`
`3. Prior to sending a unicast message to the attached router, the local host
`sets up a TC P connection with the destination host. To set up the TC P
`connection, the following happens:
`
`a. The local host sends a TC P SYN message to the attached router. The
`router routes the TCP SYN message to the exit gateway IP address.
`
`b. At this point, the setup of the EPLRS point-to-point circuit is the same
`as described above, except that a SINCGARS stub net gateway router will
`proxy-ARP for the destination host based on its client list. Multiple
`gateway routers could not respond to the ARP, but the hardware address in
`the first response will be used.
`
`c. The destination exit gateway router will read the source IP address of
`the 1P header on the TCP SYN mes sage and add a return route to the
`source IP address into the routing table. The gateway router sends a RFC
`1256 advertisement onto the local SINCGARS net advertising the
`indicated source IP address.
`
`d. The destination gateway router then routes the TCP SYN message via
`the stub net to the router attached to the destination host.
`
`0. The destination router should install a route for the originator’s source
`IP address via the gateway router that has sent the RFC 1256
`advertisement referenced in paragraph c.
`
`1“. At this point, the originating and destination hosts have a TCP
`connection setup and start transmitting the message data.
`
`4. The termination of the TCP connection and EPLRS point-to—point circuit
`is the same deseribcd in Section 3.5,] 2.], paragraph A6.

`
`FBCBZ will use a bottom-up, hierarchical approach to network monitoring.
`
`Every FBCBZ platform monitors its local router and radios via SNMP queries and
`traps for status i’ malfiinctions and provides this information to the host in the form of
`COMM Status. Additionally, SA client a“ sewer status and SA statistics are available to
`infer the health of the SA network. The host has the responsibility to monitor. fault
`isolate and repair (or call for repair of) the equipment associated with the platform.
