Question

Problem 1. RDT: Sender Utilization (20 pt.)

Recall the example of sender utilization when assuming either stop-and-wait or pipelined protocols. Assume a 100 Mbps link with 50 msec propagation delay between two hosts. Also assume the packet length is 1,500 bytes.

a) Calculate sender utilization (%) under the assumption of the stop-and-wait protocol.

b) Calculate sender utilization (%) under the assumption of the pipelined protocol that can send 30 packets without acknowledgment.
