Process each request as soon as you get it but use the scheduler
to post the reply so that it is sent 5 ms later than the current
simulation time.

psuedo-code:

void Server::recv(Packet *p, Handler *h)
{
  // Response packet (you could possibly reuse p here)
  Packet *reply = allocpkt();

  // Do whatever you need to process the request (p)
  // Fill header fields as needed in the response packet,
  // (e.g. dst address and so on)

  // Schedule it (5ms from now on) and return
  Scheduler::instance().schedule(target_, reply, 0.005);
  return;
} 

Hope this helps.
