原本用Seednet也用了好幾年了~用起來也正正常常的

但是最近發現的一件事情~在Ping一些網站時~TTL的數值會跳來跳去的~

Pinging dns.hinet.net [168.95.1.1] with 32 bytes of data:

另外做了traceroute~也發現經過的hop-count也都不一致

有經過11個~也有經過10個Router的。而且經過的Router也不盡相同。traceroute www.gmail.com也是相同的狀況。

請問一下其他Seednet使用者也是有相同的狀況嗎!?Thks

感覺似乎在Seednet之內的Routing就一直變來變去的~或許是有做Load-Balancing或是Traffic Engineering。但是這樣路徑變來變去~對一些Jitter Senstive的程式說真的實在不太好~
