HostA has established a TCP connection with HostB in a remote network. HostA is sending packets 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 #1,839. HostA now sends segments of the same application data stream in order: P: 486 bytes Q: 213 bytes
