1. consider a client and a server connected through one router. assume the router can start transmitting an incoming packet after receiving its first h bytes instead of the whole packet. suppose that the link rates are r byte/s and that the client transmits one packet with a size of l bytes to the server. what is the end-to-end delay? assume the propagation, processing, and queuing delays are negligible. generalize the previous result to a scenario where the client and the server are interconnected by n routers.
