摘要

"The system and test process development to test the layers 3 and 7 of the open systems interconnection.A test system development and process for testing the layers 3 and 7 open systems interconnection (OSI) of a communication protocol used between nodes in a network of telecomunicActions.The system comprises a simulator of the protocol (73) which simulates OSI layers 3 and 7 of the protocol communications.A local area network (LAN) (79) connected to the simulator protocol with a first interface to "fit" the Internet (78) which replaces the OSI layers 1 and 2 of the protocol communications simulatedAnd a target telecommunication node (71) connected to the LAN with the second interface to "fit" the Internet (81) and performing operations with blocks of software application to validate the use of the protocol.Communications with the target telecommunication node (71).A "porch" interface protocol (tool pig) (84) is connected to the LAN with a third interface to "fit" the Internet (83).And serves as a "porch" for a telecommunications system target emulator (72).The emulator of the telecommunications system emulates a target telecommunication node target and conducts operations by executing the code of the software application used in the target telecommunication node.The operations validate the use of communications protocol with the "software" of the target telecommunication node, without having to use the "hardware" of the target node.
