Hi,

I want to implement a congestion control algorithm for an Ad-hoc wireless
network. It means i will make some modifications to TCP and therefore in
the transport layer.
Do i need to modify the Kernel to do my implementation? or there are some
kernel modules i can modify as for the case of implementing a routing
protocol in the network layer? If both are possible what could be the
advantage or disadvantage of each? Where can i get more information?

Thank you in advance,

Nadia Ramirez

Yes.

No. You can compile the TCP/IP stack as module for easier
loading/unloading but that's all.

BTW almost rotuing protocols don't need changes in TCP/IP - they simple
use it as is and configure routes from the outside (of the kernel).
