Consider a LAN cable with a 100Mbps network link which is connecting the two campuses of SEU. The propagation delay for one way is 20 microseconds. Selective Repeat protocol is used on this link to send data with a frame size of 1MB. Transmission time is negligible between the sender and receiver. To achieve the maximum(100%) utilization of this network link what should be the value in the field of the sequence number?
