22.2 Implementation of XCP in NS

In ns, the XCP implementation can be found under ~ns/xcp directory. The protocol needs to be deployed in the TCP end points (source and receiver) as well within the intermediate nodes which is mostly the router and may sometimes be a link-layer switch as well. The end-point part of XCP code may be found under xcp-end-sys.cc,h and the router portion of the code may be found under xcp.cc,h and xcpq.cc,h.
