摘要：Several ISDN (Integrated Services Digital Network) protocols have implemented at ETRI (Electronics and Telecommunications Research Institute) in an experimental network so that functional characteristics of the protocols under test could be certified against their protocol specifications with the help of the ETRI protocol test facilities. This paper describes ETRI protocol test architecture and its application to testing the NSP (Network Service Part) protocols : MTP (Message Transfer Part) level 3 and SCCP (Signalling Connection Control Part) of the CCITT CCS (Common Channel Signalling ) system No. 7 The test architecture presented here allows tests for two different protocol classes : peer-to-peer and multipeer protocolos. Some extensions are made to the conventional test architectures, namely the test coordination, test result transfer and network state observation method.
