P1) Given the network configuration below (N routers and N+1 links of transmission rate of R bps) compute following end-to-end delays assuming zero processing, queuing and propagation delays: One packet of length L bits from hosts A to B Ppackets back-to-back from hosts A to B. (Hint: by the time the first packet reaches B, the next packet is in router N) a) b) Host A Host B Router 1 Router 2 RouterN-1 Router MN Link 1 Link 2 Link N Link N+1
