[ns] sending packets

[Jingwen Jin <jjin1@uiuc.edu>]

Hi,

I'm creating my own agents... To send a packet to a specific agent, I used
to specify "ip_header->daddr()=x" (where x is the address of the
destination agent).It worked correctly when the communication is among a
single type of agent. But as I introduced another class of agent, this
method does not seem to work anymore. Packets are sent and received
to/from wrong agents. So what's the correct way of specifying destination
of a packet? (via flowid??)

Thanks for your attention,

Jingwen
