Data link layer sliding window protocol design and implementation: use their data link layer theory, their own design of a sliding window protocol, in the simulation environment, programming of the noise channel without the two error-free duplex communication between sites. Channel model is 8000bps full duplex satellite channel, channel propagation delay of 270 milliseconds, the channel bit error rate of 10-5, the channel provides a byte-stream transfer service, the network layer packet length is 256 bytes fixed
