HostA has established a TCP connection with HostB in a remote network.

 

HostA has established a TCP connection with HostB in a remote network. HostA is sending segments to HostB. Assume we have configured TCP, somehow, to ACK every segment (no ACKing every other segment). Assume that the timeout is the same for all packets. HostB's "window size" is 20000 bytes. HostB has already received and acknowledged everything sent by HostA's application up to and including byte #3,091. HostA now sends segments of the same application data stream in order: P: 489 bytes Q: 217 bytes R: 222 bytes What is the sequence number on segment R?
