摘　　要：为解决IP报文传输过程中存在的丢包和时延抖动超限问题,在讨论协议转换器对QoS的影响及分析QoS影响机理的基础上,设计了一种对其QoS指标及其动态范围进行定量测试的方法,测试结果表明,协议转换器在通信业务存在大数据量突发条件下,无法对其他实时业务提供QoS保证。根据测试结果设计了系统QoS部署方案的优化措施,试验表明该优化方案很好地解决了广域网端到端通信的QoS问题,降低了构建广域网的难度。In order to solve the problem of packet loss and delay jitter overrun during IP packet transmission,the influence of protocol converter on QoS and the influence mechanism of QoS are discussed.A quantitative test method of QoS index and its dynamic range is designed.The test results show that the protocol converter can not provide QoS guarantee for other real-time services under the condition of large data burst.According to the test results,the optimization measures of the system QoS deployment scheme are designed.The test results show that the optimization scheme solves the QoS problem of the WAN end-to-end communication and reduces the difficulty of building the WAN.
