摘要： PROBLEM TO BE SOLVED: To perform an end-end continuity characteristic test without using a measurement instrument and without providing advanced test functions to a user access device. SOLUTION: The system has a test function in a relay device which constitutes a relay network wherein a plurality of user access devices are multiplexed. An end-end continuity characteristic test is performed using the relay device as a test starting point. The relay device sends a test frame to one user access device, and the user access device loops back the test frame to the same port. The relay device transmits the loopback test frame, and transfers the test frame to an opposed user access device. The opposed user access device returns the test frame to the same port. The relay device which is a test starting point terminates the test frame which is looped back again from the opposed user access device. Throughput and a delay time are calculated based on information contained in the test frame. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that access to CAM and external RAM increases and power consumption increases since a hit rate to internal RAM and FF of connection with a large traffic amount is reduced as an average in a case when access frequency to CAM and external RAM cannot be reduced by an inputted traffic pattern with a method to always update a cache (internal RAM and FF) by a retrieval result of CAM and external RAM.SOLUTION: Connection whose passage frequency is high is previously registered in internal RAM and FF, and a registration connection is not updated in accordance with access to CAM and external RAM. Since the registration connection of internal RAM and FF is changed in accordance with actual passage frequency, a registration entry of internal RAM and FF is updated in accordance with a passage situation of traffic in a past prescribed period.
