趁着DDoS这段时间,测了下到Github的线路情况,但无奈手里的数据中心不多,想请有其他数据中心的朋友帮忙测下。我对国内的尤其感兴趣,因为出国线路不是一直说数据中心有优先级嘛?
我目前的研究小结——
测试结果——
as线路
走北美Linode到Github:AS6939(HE)-> AS32787(Prolexic,Akamai)-> AS36459(Github)
走香港Rackspace到Gtihub:AS45187(RS)-> AS32787 -> AS36459
走深圳电信到Gtihub:AS4134 -> AS2914(NTT) -> AS32787 -> AS36459
traceroute + ping
北美Linode到Github:12 hops,掉包率<1%
香港Rackspace到Github:14 hops,掉包率<10%
深圳电信到Github:20 hops,掉包率>50%
我个人用的工具包括Mac的traceroute和ping,以及iOS上一个叫NiceTrace的收费小工具,HE.net也有一个免费的工具,但不知道是否能显示AS数。
https://itunes.apple.com/us/app/nice-trace-traceroute/id322722672?mt=8
https://itunes.apple.com/us/app/he.net-network-tools/id858241710?ls=1&mt=8
想请各位在自己的数据中心上收集类似的数据:AS线路,traceroute的hop数,以及100次ping github.com
的平均掉包率。
PS: 用traceroute -a github.com
就能显示AS值。当然,AS准不准还看要默认设的AS Server了(可用-A
指定一个,说实话我不知道哪里有开放的as server列表)
PPS: 某程度上我在寻找类似 https://lg.he.net/ 一样可以用来测traceroute和bgp route的工具。看了下国内的,似乎bgp route比较少,也不大容易搞清楚是不是从数据中心发起的(ISP倒是写着,电信、移动什么的)。

试下http://www.ipip.net/
他们的网站有traceroute功能 |

bitinn OP @a540355686 oh,还真有AS号,不错 http://www.ipip.net/traceroute.php

手头上公司的五个机房加上个人的日本东京linode机房测试结果:
https://gist.github.com/unkstar/3bb1f3203f3725529ab4 吃完饭重新测了一次北京亦庄电信,github和sourceforge都不丢包了: --- github.com ping statistics --- 100 packets transmitted, 100 received, 0% packet loss, time 99063ms rtt min/avg/max/mdev = 244.597/277.262/349.799/25.215 ms --- sourceforge.net ping statistics --- 100 packets transmitted, 100 received, 0% packet loss, time 99085ms rtt min/avg/max/mdev = 231.281/233.027/236.094/1.375 ms 但是无锡移动还是餐具: --- github.com ping statistics --- 100 packets transmitted, 79 received, 21% packet loss, time 100837ms rtt min/avg/max/mdev = 266.980/268.159/284.959/2.314 ms --- sourceforge.net ping statistics --- 100 packets transmitted, 100 received, 0% packet loss, time 99047ms rtt min/avg/max/mdev = 257.110/257.919/271.878/1.720 ms |

ntt丢包>60-70%了.
网络工具测的. 仅在上传流量中有异常,下行没啥问题. |

AS4809 -> AS2914 -> AS32787 -> AS36459
NTT 倒是不丢包,Prolexic 丢啊。。。。 |

趁出国网络通常比较好的早上测了下,线路没变 AS4134 - AS2914 - AS32787 - AS36459,但掉包率下来了。目前是0%。各位有空可以测下。 我不知道和Github北京时间今早调整了DDoS的对策是否有关。 https://status.github.com/messages |

@bitinn 试了 完全没变化 除了延时从200掉到180……
