【Abstract】 The online test is to test protocol through the protocol session observed online and the states of the session partners needed to be determined.In this paper,the state synchronization algorithm is presented to transform the traditional protocol state machine into a “state event table”,thus the states of session partners are calculated through table work.This algorithm solves the premise of determining the states for the online test.A complexity analysis shows the factors affecting the algorithm and corresponding improvements are made to further reduce the complexity.This algorithm has been exploited in the online test system developed by the authors and conformance test and interoperability test have been performed on several protocols,including communication protocols and routing protocols,through which the validity of the algorithm is proved and beneficial results are acquired.更多还原
