Extracted text: Consider a full-duplex 256 Kbps satellite link with a 240 millisecond end-to-end delay. The data frames carry a useful payload of size 12,000 bits. Assume that both ACK and data frames have 320 bits of header information, and that ACK frames carry no data. What is the effective data throughput: a) When using Stop and Wait? b) When using sliding windows with a sender window size of W = 5 data frames? Note: that the effective data throughput in reliable data transfer is defined to be the ratio of the amount of useful data sent by the sender divided by the total time elapsed from the moment the first bit of the frame containing this data is transmitted to the moment the last bit of corresponding ACK is received by the sender.
