Title:
UNIX開放型システム間相互接続層のテスト
Document Type and Number:
Japanese Patent JP3706145
Kind Code:
B2
Abstract:
A development test system and method for testing Open Systems Interconnection (OSI) layers 3 through 7 of a communications protocol utilized between nodes in a telecommunications network. The system comprises a protocol simulator that simulates OSI layers 3 through 7 of the communications protocol, a local area network (LAN) connected to the protocol simulator with a first Internet socket interface which replaces OSI layers 1 and 2 of the simulated communications protocol, and a target telecommunication node connected to the LAN with a second Internet socket interface and performing operations with blocks of application software to validate the use of the communications protocol with the target telecommunication node. A protocol interface gateway (PIG-tool) is connected to the LAN with a third Internet socket interface, and serves as a gateway to a target telecommunication system emulator. The target telecommunication system emulator emulates a target telecommunication node and performs operations by executing the code of the application software utilized in the target telecommunication node. The operations validate the use of the communications protocol with the target telecommunication node software without having to utilize the target node hardware.
