电信级以太网测试技术

为了比较不同电信级以太网（CE）技术方案的优劣，文章依据城域以太网论坛（MEF）定义的电信级以太网的特点，针对可扩展性、可靠性、服务质量（QoS）、业务承载能力以及业务管理等方面描述了相应的测试方案。通过实际的测试可以看到，目前的电信级以太网技术在以上几个方面均能基本满足电信级组网的需求。但是，由于不同的电信级以太网解决方案在业务承载能力、可靠性、扩展能力、服务质量（QoS）以及运营管理维护（OAM）能力方面存在着较大的差异性，在短期内难以实现完全的互联互通。

Testing Technology for Carrier Ethernet

In order to compare the effectiveness of different Carrier Ethernet(CE) technologies,test methods are described based on the features of CE defined by Metro Ethernet Forum(MEF),including scalability testing,reliability testing,Quality of Service(QoS) testing,service bearer capability testing and service management testing,etc.It can be seen from the test results that the present CE technologies could satisfy basic requirements of carrier-class network on the abovementioned aspects.However,complete interconnection could hardly be achieved between different CE solution projects in the short term because of major diversities,existing in those projects on the aspects of service bearer capability,reliability,scalability,QoS and Operation Administration and Maintenance(OAM) ability.
