- "ns srm-demo.tcl": a Reliable Multicast demo using nam.
- From the change log: "a simple, completely contrived script to generate
- SRM-like sample paths to illustrate SRM".
- At time 1.0 a CBR source at node 14 starts sending (red packets) to
- group B, which has nodes 0-8 as members.
- Receivers are of type "Agent/Message/MC_Acker", and send an ACK (white
- packet) unicast to the source for every packet.
- Starting at time 1.5, receivers at nodes 0-8 are of type
- "Agent/Message/MC_Nacker", and send unicast NACK packets (blue)
- to the origin sender.
- Congestion is created by unicast connections (yellow packets),
- causing multicast packets to be dropped also.
- Starting at time 3.0, receivers at nodes 0-8 are of type
- "Agent/Message/MC_SRM" using deterministic behavior, and at a
- deterministic time send NACK/request packets multicast to the group.
- Starting at time 3.5, receivers at nodes 0-8 are now of type
- "Agent/Message/MC_SRM" using randomization. Using randomization to
- determine when to sent a request, a receiver sends the
- request multicast to the group.
