Method for monitoring performance of metro Ethernet

Abstract

The invention discloses a method for monitoring the performance of metro Ethernet. The method comprises traffic statistics of an Ethernet port and statistics based on the SLA flow. When the monitoring is carried out on the traffic statistics of the Ethernet port, connection between the ports of two interchangers is ensured firstly, and then the monitoring function is carried out globally and the flow statistics function of the Ethernet port is achieved under the connected ports. When monitoring is carried out on the statistics based on the SLA flow, normal communication between the two interchangers based on Y.1731 is ensured firstly, and then the monitoring function is carried out globally and the statistics function based on the SLA flow is achieved in the SLA mode. Finally, corresponding statistics results are displayed according to minimum statistics time intervals respectively. The method for monitoring the performance of the metro Ethernet achieves organic integration of the interchangers and an Ethernet performance testing meter, is capable of carrying out long-time online monitoring on performance indexes of the Ethernet such as port flow statistics property, time delay, delay variation and packet loss probability, has an Ethernet performance index ultralimit network management warning function, and has guiding significance for effective management and maintenance of the metro Ethernet.

Description

technical field [0001] The invention relates to performance monitoring of the metropolitan Ethernet, in particular to a method for monitoring the performance of the metropolitan Ethernet. Background technique [0002] Along with the development of Internet network technology, the traditional Ethernet is gradually expanding from LAN to MAN. [0003] When the traditional Ethernet is applied in the local area network, due to the simple use environment and mainly carrying data services, its architecture is usually a simple plane without layering. Therefore, the performance parameters of Ethernet are based on independent stand-alone devices or simple point-to-point networks. Offline testing generally does not involve performance monitoring of SLA (service-level agreement, Service Level Agreement) traffic statistics. [0004] However, in Metro Ethernet, the relationship among customers (Customer), provider (Provider) and operator (operator) is intricate, and the service provider ...

Problems solved by technology

[0004] However, in Metro Ethernet, the relationship among customers (Customer), provider (Provider) and operator (operator) is intricate, and the service provider network downlinks complex and huge user networks, and its own network usually requires different operators to provide Operation and maintenance services, therefore, it is required that metro Ethernet can carry integrated services and be able to flexibly distinguish various services through SLA
