what is the minimum number of distinct sequence numbers that we would need for this protocol to work correctly? why?

The minimum sequence number for Selective-Repeat protocol should be 2*(N+M) to handle both new packets and retransmissions.The send window size in Go-Back-N ARQ must be less than 2m, but the receiver window size is always 1. The size of the send window in Stop-and-Wait ARQ, a particular instance of Go-Back-N ARQ, is 1. The sender and receiver windows in Selective Repeat ARQ must have a maximum size of 1.5 m. If N is the largest window size possible, then 2N sequence numbers are needed. In other words, for selective repeat to work properly, we need N 2n / 2=2n-1 with n bits available for sequence numbers.Learn more about window here-https://brainly.com/question/13502522#SPJ4
