摘　　要：随着网络应用的不断发展,用户对网络服务的质量要求越来越高。网络质量是否快速有效和安全可靠是衡量网络服务的关键。用户为应用数据打上服务质量标签,传输过程中通过多协议标签交换技术对标签数据进行处理转发,却会在一定程度上损失有效性和高优先级。使用当前常用的城域以太网设备进行模拟试验分析,模拟数据在不同接入方式下经过传输后的服务质量变化,最终测试验证了设备在特定传输模式下会对部分数据的服务质量标签进行更改。为了网络能提供高效的服务,提出了针对城域以太网的设备优化和部署的方案。测试验证,采用这些措施,网络的服务质量能够得到有效提升。With the continuous development of network applications,the requirements for the quality of network services are higher and higher.The key to measure the network quality is whether it is fast,effective,safe and reliable.Users label the application data with quality of service.In the process of transmission,the label data is processed by multi-protocol label switching technology,but after forwarding,the validity and high priority will be lost to a certain extent.This paper uses the currently commonly used metro Ethernet equipment for simulation test analysis,and simulates the service quality changes of the data after transmission under different access methods.Through the test,it is verified that the device will change the quality of service label of some data in a specific transmission mode.In order to provide efficient services for the network,the scheme of equipment optimization and deployment for Metro Ethernet is proposed.After testing,it is verified that the service quality of the network can be effectively improved by using these measures.
