Abstract: Based on the analysis and the perception of routing protocols, this paper presents an online test method applicable for the routing protocol test. This method tests the protocol implementation through online observation. It can be performed in production field without interfering to the network and possesses quite a lot other beneficial features. With the key techniques were worked out, the target and the framework of an online test system (OLTS) are put forward. The OLTS exploits the state synchronization algorithm to test the protocol state machine, tests the exchange and the manipulation of the routing information through the topology analysis and the internal process simulation. OLTS provides an intuitionistic and friendly graphical user interface and good flexibility. Now the prototype of the OLTS has been implemented and the test activity about BGP, OSPF and RIP has been performed.
