[ns] Question about token ring implementation

[Marise-Marie D'Costa]

Hello

We have a question about the implementation of token ring in NS. We are
able to construct nodes and full-duplex links, and also generate traffic
between the nodes. The problem we have is to just send ONE packet between
nodes which will represent a token, we are not sure what sort of an agent
to set up for this, since for traffic generation, we have a CBR agent.

Please let us know how we can do this.

Thank you
