... 2. We transfer a 6 M byte message through a network with the bandwidth of 400 Kbps, using the Go-back-N ARQ protocol. The sender window size is 4, and the receiver sends ACK for each data frame. Each data frame carries 2,000 bits of data. Assume that the distance between the sender and the receiver ...
