Re: Processing delay

[Guillermo Rigotti <grigotti@exa.unicen.edu.ar>]

Hi,

I hope I've understand you problem:

You have an agent; it receives a packet and process it; during this
process, if the agent
receives another packet, he discards or enqueue it.

A simple solution is to have a flag and test it in handle (recv) method
of the agent. If
flags = busy, discard the packet.To give values to the variable flag:
when the agent
receives a packet, he puts flag=busy and generates an event (at-event)
to set flag=idle
in the desired amount of time using a new method added to the agent.

$ns at expr [ [$ns now] + $delay_time] ] "$ self set_flag $idle"

This solution has the adventage thas is completely implemented in Otcl.

Regards,

Guillermo
