Compute the fraction of the bandwidth that is wasted on overhead (headers and retransmissions) for sliding window protocol using selective repeat on a heavily loaded 50 kbps satellite channel with data frames consisting of 40 header and 3960 data bits. ACK frames never occur. NAK frames are 40-bits. The error rate for data frames is 1 percent and the error rate for NAK frames is negligible. The sequence numbers are 8-bits.
