Method of testing a router, and a test system

摘要

This method of testing a router in a test environment that is isolated from an operational telecommunications network comprises initially collecting data from a node of said operational network by copying data packets being conveyed thereby, and then: a step of modifying collected data packets, this step comprising at least one substep of replacing the identity data of the original senders and receivers of the collected packets with identification data for senders and receivers in the test environment; and a step of testing the router and comprising at least one substep of routing modified data packets via said router in said test environment.
