METHOD AND DEVICE FOR TESTING AND EVALUATING DYNAMIC FUNCTIONAL OPERATION OF REGIONALLY DISPERSED COMMUNICATION NETWORK

摘要

PURPOSE: To test and evaluate a functional operation of a packet exchange communication network in real time. CONSTITUTION: A test packet formed by inserting various test information to a payload part of the packet consisting of a control block, including output addresses and the payload part is stored in a memory of a transmission unit 24, prior to the start of a test run. The test packet is sent to a specific reception unit 25 at a high speed from a transmission unit 24, via a packet exchange network (PSS) under the control of a transputer 28. The reception unit analyzes information of the test packet, received under the control of a transputer 29 in real time to discriminate whether or not an undesired outcome has been produced. Since the test information is inserted to the payload part of the packet, an enormous amount of test information is transmitted, by which many kinds of errors are discriminated. Further since the test packet is transmitted at a high speed by the hardware of the transmission unit test can the made in real time, up to a fault with a low occurrence rate.
