TCP opens a connection using the initial sequence number (SN) 12534. The other party opens the connection with ISN 23763. The client sends 2000 bytes of data in four segments. The server then sends 2000 bytes in one segment. Use a message sequence diagram, and explain in detail the TCP based communication process.

What does TCP service model mean? In what ways does the TCP segment header play a role in delivering these services?

SInternet Check sum Consider the figure below (simplex communication scenario). The TCP sender sends an initial window of 4 segments. Suppose the initial value of the sender ན༽)། sequence number, SEQ1, is 100 and the first 4 segments each contain 400 bytes of payload. As you can see ACK 3 is lost. What is the SEQ number (SEQ2, SEQ3, SEQ4, SEQ5) from the Sender and ACK Number (ACK1, ACK2, ACK3, ACK4, ACK5) from the receiver for each segment? Sender Seq1 Seq2 Seq3 Seg4 ACK1 ACK2 ACK3 ACK4 Seq5 ACK5 Receiver

If there is wide variation in the TCP segment size , it is natural to organize the buffers as a pool of fixed-sized buffers, with one segment per buffer TRUE OR FALSE
