The Reference Implementation (RI) is an important part of the test system. It gets data and command from Test Execution (TE) and sends packets to the Implementation Under Test (IUT) and receives its response. In this paper, the techniques exploited to enhance the RI are discussed. With such sub-modules as data generation and dynamic calculation introduced, the processing ability of the RI is strengthened. With multiple channels, the observability and the controllability are expanded. In order to cope with testing in high-speed network, the RI is divided into acceptance sub-layer and submission sub-layer. Cooperated with other techniques such as frame extension, the functions of RI are enhanced to overcome the problems encountered when testing routing protocols. The flexibility and the efficiency are increased while the compatibility remains. The enhanced RI plays an effective role in routing protocol test.
