以太网专线等效环路测试方法研究

Research on Equivalent-loopback Test for Ethernet Private Line

在为企业开通分支点汇聚到中心点的以太网专线业务时,测试工程师需要对带宽、丢包率、时延等电路指标进行端到端测试。业务开通效率直接影响客户感知,如何简化测试方法、压缩开通历时、避免业务中断已经成为业务开通工作的重要课题。等效环路测试方法克服了传统方案的缺点,在不影响汇聚端口中其他业务、无需客户和网管人员配合的情况下,测试工程师能够独立完成电路端到端测试。等效环路测试方法提高了业务开通效率,提升了客户满意度,具有很高的应用推广价值。

When enterprise opens Ethernet private line from branch to headquarters,engineers need end-to-end testing of circuit quality indicators such as bandwidth,packet loss,and latency. Business opening efficiency directly affects customer perception. How to simplify the testing method,reduce the opening time and avoid business interruption has become an important issue in business opening.The equivalent-loopback test for Ethernet private line overcomes the shortcomings of existing methods. Without affecting other business in the convergence port and without the cooperation of customers and network managers, the test engineer can independently complete the end-to-end test of the circuit. The equivalent-loopback test method improves business opening efficiency and customer satisfaction,and has high application and popularization value.
