Abstract
A protocol analyzer is provided for monitoring a selected communication connection being conducted in accordance with a predetermined protocol by the exchange of protocol data units between two entities over a data network. The analyzer includes a monitoring device for identifying protocol data units, a protocol-follower conditioned in dependence on said predetermined protocol and operative to follow the progress of the connection as it receives relevant protocol data units from the monitoring device, and an alarm indicating when the sequence of protocol data units diverges from the protocol. The protocol data units are passed through a FIFO store as they are used by the protocol-follower, so that on a protocol violation occurring, the sequence of protocol data units leading up to the violation can be extracted from the FIFO store and displayed. The protocol analyzer thus filters out protocol data units conforming to the relevant protocol so that only protocol data units violating the protocol, together with the immediately preceding protocol data units, are displayed.
