Ejercicio 1 - Part 2

A machine A (client), whose TCP entity is going to establish a connection with the TCP entity of another machine B (server). Both entities, A and B, manage reception windows of 512 and 256 octets respectively, and maximum segment sizes to send (MSS) of 64 and 128 octets also respectively. Consider that each segment's transmission takes place at the start of a 'tick' on the clock, and each segment suffers a constant delay of one 'tick' in the network until it reaches the opposite entity. Furthermore, if two segments are to be sent simultaneously, they are sent consecutively.

Represent the TCP connection diagram, followed by the frame exchange where A sends three complete data segments to B. Assume that during the third segment establishment of the connection, data is being sent, and that the sending of acknowledgments follows the policy of ACK generation described here. Additionally, assume that A starts with SN=1023 and B with SN=2047.
