(a) Consider the following IPv4 parameters: 10.2.2.20/30 and 10.2.2.199/26. Identify the address of the next network in each case. Show and explain how you obtained these network addresses. [10 Marks] (b) In the context of sliding window flow control (i) A 7-bit sequence number used in a Go-Back-N error control scheme. What is the maximum number of frames that a sender can transmit without the need for an ACK from the receiver? (ii) In a Satellite link the Round Trip Time is 300ms. Similarly, the transmission time for a frame is 200μs. What is the efficiency of the protocol if stop and wait is used? Why is the stop and wait protocol inappropriate for links with long delay and short frame times? [10 Marks] (a) Consider the following IPv4 parameters: 10.2.2.20/30 and 10.2.2.199/26.
