[ns] Implementation of WRED

[Alexander Sayenko]

Re: [ns] Implementation of WREDHi

Those policy, edge and core routers are not complicated, especiall if everything you want to test is WRED. Furthermore,  you can always create a simple DiffServ network, which has only the edge router.

source -- edge -- destination

If you do not want to configure all the policies and meters, you can always use the so-called NULL meter.

  Hi!
  Thank you so much, it has given me a direction.
  However in Diffserv, we would need to define the policy, edge and core routers. How should we define it in this case if we want to use wred?
  Just to clarify, can i say that dsred and wred are similar?

  thanks!
  zoe

  Hi

  The implementation of WRED is available is a part of the DiffServ framework.
  Thus, you can either use the DiffServ framework or take a look at the
  implementation and port it to the NS-2 basic scheduling framework.
