Question

Berkeley Computer Science example (CS-168):

Picture this: there are two hosts (A and B). The two hosts are connected by 50 msec of propagation delay. The bandwidth is equal to 10⁶ B/sec. Note that the hosts use a sliding window where (W = 4, and packet size = 1000 Bytes) with (Selective Repeat). We will ignore the size of ACK and assume that the timer value for each packet is set as (send time + RTT) and retransmission occurs immediately after a timer expires. Make sure to assume that the packets are sent in sequence starting at time 0. How long does it take to successfully receive all 4 packets (P_0, P_1, P_2, P_3). Your answer should be in milliseconds.

1. When there is no packet loss.

2. When the P_1 packet becomes lost, but there is no further packet loss
