[ns] TCP ACKs - change route

[Rafiq Shaikh]

Hi Tatiana,

I am also looking for the answer to the same question.

In my simulation I need to send TCP ACKs on a different route as compared
to the TCP data packets. Since I am using wireless MAC the concept of link does not apply there. Hence, the routing related command does not apply to my scenario. Which means I will have to hack in the code to force the ACK 
packets to take a specific path. As of now I am not sure how to do that.

However, I read in the manual that all the route specific commands use link
concept. The link concept is applicable to wired scenarios. I believe if you are using wired links then it should be possible to use "rtproto manual" or "rtproto static" or something similar to achieve the forced routing of the ACKs.

I hope this helps.

Regards,
-Rafiq.
