programmable router

[Kaustubh Agarwal]

Hello Everyone!,

I am a beginner who is learning about NS3.

I am working on an  application. My setup is attached in this post.

I am assuming that Node 1 is sending packets destined for both node 3 and node 4.

I want to configure the simulation such that whenever Node 2(Router) receives a packet destined for Node 4, it transmits it

and starts buffering the future packets(any) for 1.5msecs(the node does not transmits any packet during this duration).

After this time the the system can resume working as usual.

How can I achieve this?

Any help is appreciated.

Kind regards,

Kaustubh
