COMP 311 Computer Networks

1. Show that In the Go-Back-N protocol, the size of the send window must be less than 2K where K is the # of bits for sequence numbers ; the size of the receive window is always 1. Use the timeline diagram for K = 4 to show the solution.

2. What would be the relationship between the sender window size an the # of sequence bits in Selective-repeat protocol? Show the timeline diagram for K = 4 to show this relationship.
