网络丢包问题求证，是墙的干扰吗？

[standin000]

又不是完全封锁，只是ping 丢包。

用mtr测 traceroute看不清问题。但是ntt段的基本是拥塞导致的 和墙没啥关系

[standin000]

@bellchu ntt段堵塞是运营商的原因吗？可以用什么深度测试了？

[bellchu]

mtr是icmp和trace双重测试 可以比较直观地看出各段hop之间的质量

[bellchu]

@standin000 去北美很多路由都是汇总到ntt和kddi的 甚至有的去香港的都要从ntt和kddi绕 应该是运营商出口拥塞

@bellchu 谢谢，请看下mtr的截屏

@standin000 上海电信这个时段这个丢包率已经很不错了
前几个月202.97的骨干网丢包率都是90%以上的

另，电信这两天去北美的很多路由都从联通的骨干网绕道，不知是出了什么问题。

@standin000 PS，看是否是墙干扰最好同时从服务器端MTR到你电脑看看情况。
