摘要： PROBLEM TO BE SOLVED: To shorten time required to detect a fault while suppressing influence on a network.SOLUTION: A maintenance entity group end point (MEP) 10 performs transmission and reception of packets between it and its opposite MEP. The MEP 10 includes a transmission/reception available band calculation unit 16, a period calculation unit 18, and a transmission module 112. The transmission/reception available band calculation unit 16 calculates an available band usable for transmission and reception of maintenance packets in a band usable for transmission and reception of the packets. The period calculation unit 18 determines a transmission interval of the maintenance packets on the basis of the available band calculated by the transmission/reception available band calculation unit 16. The transmission module 112 transmits the maintenance packets to the opposite MEP at the transmission interval determined by the period calculation unit 18.

摘要： PROBLEM TO BE SOLVED: To automatically acquire necessary configuration information and network information when executing various tests about a network by using a maintenance program. SOLUTION: The communication equipment A transmits an LBM frame using the multicast LB function of an Ethernet-OAM (Ethernet-Operations Administration Maintenance) protocol, and specifies the transmission source of an LBR frame as an MEP (MEG (Maintenance Entity Group) End Point) to acquire MEP information showing information about an MEP when receiving the LBR frame as a response. After that, the communication equipment A transmits to the specified MEP an LTM frame using the multicast LT (Link Trace) function of the Ethernet-OAM protocol, and specifies communication equipment to be an MIP from the LTR frame to acquire MIP information showing information about the MIP when receiving the LTR frame as a response. Then, the communication equipment A generates topology information showing the configuration of the network from the acquired MEP information and MIP information. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To perform active evaluation without exerting adverse effects on actual network operation. SOLUTION: In a load testing system, a transmission device measures a bandwidth of user data transmitted from a user terminal in real time, calculates calculation bandwidth, by subtracting the bandwidth of the user data measured from an arbitrary evaluation bandwidth preset to evaluate the performance of a network, and transmits test data corresponding to the calculation bandwidth, together with the user data corresponding to the bandwidth of the user data used. A receiving device receives the user data and the test data concurrently transmitted with the user data, and evaluates the performance of the network, on the basis of the user data and test data received.
