Hello: We have a custom TCP stack and would like to verify our TCP Reassembly functionality. Can somone please give some ideas on how to test this. The scenarios to be created and tested are creating out of order pkts, packets with overlapping sequence numbers etc. I looked at using divert sockets. Probably that is one of the ways to generate such pkts. But, I am not very sure how it would work for us (or does it even work in this situation?). Could someone please share their experiences with using divert socket to do something like this. Also, if someone would like to share their experiences ways of testing TCP reassembly, I will really appreicate it. Thanks for your help, Vishal.
