Unformatted text preview: Which one is responsible for the routing? Problem #3 (i) Explain why the SRP and the GO BACK N protocols, both with window size W = 1, are equivalent to the ABP protocol. (ii) What do the round trip assumptions and W = 1 imply about the propagation time and the acknowledgment transmission time for the above protocols? (iii) Derive the efficiency of the ABP under round trip assumptions. Assume that the probability that a packet or its acknowledgment is corrupted by noise is equal to p . Show that this efficiency is, as expected, the same as the efficiency of the GO BACK N protocol with W = 1. file:///C/Documents%20and%20Settings/Jason%20Raftery/M. ..ering%20122%20%20Spring%201991KonstantopoulosMT1.htm1/27/2007 3:52:18 PM...
