Consider a link between a Server and a Client that is the concatenation of N links, each of which has a packet loss probability p, and suppose that packet loss probabilities are independent for each link. What is the probability that a packet, sent from the server, is received at the client side? If a packet is lost in the path, the server will know and retransmit a new packet. How many times, on average, will the server have to send the packet over the link?
