以下是今晚感受到明显卡顿时候的 ping 数据,插着网线,已排除路由器问题
情况就是连百度搜个东西页面都要好一会才出来,游戏直接卡掉线
猜想是今年大量学生搬到这个校区 + 宽带从 10M 提速到 20M (上海电信)导致的负载过高?
120.27.112.111 延迟正常应该在 22ms 左右
172.20.6.10 为内网系统地址

难道不应该是静默上传导致的吗, 比如有人用 X 酷客户端, 有人用 X 雷, 有人用 XX 音乐
尝试同时 ping 一下路由器, 按照排除了路由的原因, 按道理 LZ 是完成了这一步的. 直连猫, 或者用路由看客户端的网络占用情况 |

@Laynooor 好像单纯限制上传解决不了上传的问题, 比如限制上传为 50Kb/s, 结果机器有正在上传的应用会占满这 50Kb/s, 也会导致 ping 延迟的..
如果你们已经多方确认了是校园网络问题可以考虑投诉, 人多力量大, 解决速度也会快些. |

@Laynooor 学校不理的话就只能搞个大新闻了,如果你们学校网络是外包给别的公司,那就更加难搞了……

有可能是运营商的设备处理能力没跟上吧,我们学校 14 年左右经常晚上卡出翔,上太阳风分析,最后发现部分楼栋汇聚是百兆上联到核心,全部换成双千兆做 eth-channel 绑定,再也没卡过。
