some questions about the implementation of tcp #12

Open hdtjiang opened 7 years ago

hello,Yibo. I have tested the tcp-flow in the project.But the sequeueNumber in mix.tr is always 42. Does this mean that the receiver cannot receive the packets and send back NACK? And the codes about generate NACK and ACK in qbb-net-device is used for UDP only? Waiting for your reply.

The sequence number in mix.tr is only meaningful for UDP packets.

Yes, NACK generation is for UDP flows only.
