An Analysis of Data Link Control Protocols

In this chapter we analyze the performance of data link protocols. We consider Stop and Wait ARQ and Sliding Window protocol. In Sliding window protocol, we consider Selective Reject ARQ and Go-Back-N ARQ. There are existing results that analyze the link utilization of these protocols in the presence of error. We have experimented in a somewhat more generalized framework. We have also analyzed and experimented with the number of duplicate error-free packets that will be transmitted.
