The SDL Specification of the Sliding Window Protocol Revisited
We present the results of a case study in which the use of SDL tools was analysed on the basis of the sliding window protocol. We chose the SDL specification of the protocol which was first published by the ISO. While editing and simulating the SDL specification we found out that the specification contains significant errors and does not meet the informal description of the protocol. We describe these errors and give a correct version of the SDL specification.
