Ejercicio 1 - Parte 3

Suppose a machine A (client), whose TCP entity has already established 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 frame exchange diagram, where A sends 3 segments to B and B sends 2 segments to A, all of maximum possible size, where the first segments of A and B are sent in the same 'tick' (all segments arrive at the destination correctly). Assume that the sending of acknowledgments follows the policy of ACK generation described here. Additionally, assume that A starts with SN=1024 and B with SN=2048.
