System for testing a network component by selectively modifying messages received from the component and returning to a simulator

摘要

A system for testing one or more communication network components comprising a network entity simulator for emulating message communication among network entities and the one or more network components under test, and a message processor for intercepting predefined messages between the network entity simulator and the network components to examine, change, or delete intercepted messages. A scheduler arbitrates usage of processing among the components, and a language processor provides an interface for a tester to control the simulator and message processor.
