Abstract:We prove the correctness of a two-way sliding window protocol
with piggybacking, where the acknowledgments of the latest
received data are attached to the next data transmitted back into the channel. The window size of both parties are considered to be finite, though they can be of different sizes. We show that this protocol is equivalent (branching bisimilar) to a pair of FIFO queues of finite capacities. The protocol is first modeled and manually proved for its correctness in the process algebraic language of muCRL. We use the theorem prover PVS to formalize and to mechanically prove the correctness. This implies both safety and liveness (under the assumption of fairness).
