互联网跨域端到端质量监测及故障定位方案

Internet cross-domain end-to-end quality monitoring and trouble location scheme

随着互联网市场的迅猛发展,互联网内容提供商对网络质量提出了更高的要求。大型互联网内容提供商因业务需要,应用遍布于各地数据中心,对互联网跨域访问质量有很高的要求。建立互联网跨域端到端质量监测系统,快速定位域外网络故障,对互联网运营商及服务提供商具有较大的意义。分析了常用网络监控技术和等价路径中的散列(Hash)算法,提出利用散列算法实现网络路径全遍历,监测互联网跨域端到端质量,最后对故障定位方案给出了建议。

With the rapid development of internet, the internet content providers need much better quality of internet. They usually need to deploy their applications in the internet data centers all over the country due to their business requirements. Users usually cross domain to access in their data centers. So internet content providers have high level of requirements for cross-domain internet quality. It is very important for internet service providers to establish a monitoring system which could monitor end-to-end cross-domain internet quality and locate the troubles of network out of autonomous systems rapidly. The commonly used network monitoring technology and the hash algorithm in equal-cost multipath routing were analyzed. A solution of using Hash algorithm to realize full traversal of network paths and monitor end-to-end cross-domain internet quality, was presented. Some suggestions were also given for trouble location scheme.
