B.2.8 TCP Multicast
The DS2000-TS supports a broadcast feature that lets the user configure TCP multicast groups. A maximum
of 50 TCP sources can be defined, which can connect to a maximum of 60 destinations. Traffic received on
the source IP address and socket is sent to each of the destinations; any traffic received on the destinations is
sent only to the source. When a user connects to the source IP address and socket, TCP connections are
automatically launched to the destinations. If a destination is cleared, the DS2000-TS attempts to reestablish
the connection every 10 seconds. If the source is cleared, all destinations are cleared.
The source must be configured first; this is done by defining a Multicast async service type. The destinations
are configured from the Multicast Destinations screen, which is found under <2> Network, <1> Router,
<10> TCP Multicast. The Multicast Destinations screen is shown in Figure B-19.
