分享一個國家高速網路與電腦中心的測速站

對外頻寬小弟查到的是2GB,主要頻寬應該是Tanet的學術網路

如果您的ISP對不常用的PORT有做QOS或是對學術網路頻寬不足,測試出來的數字就不會很漂亮.

小弟公司的億聯20m測試數據.

可以發現億聯有可能是對TANET塞車,或是最常用PORT以外的PORT作上傳限速

做一下TRACERT

有興趣的朋友歡迎一起上來分享結果,小弟過一段時間會做一下統計,不過小弟猜ISP很快就會對此網站使用PROXY,所以要測的朋友要快.

這邊補上twnic的資料:

東森(EBT/APOL)是4G
速博是1G
Seednet是1G
台固是2G
其他的大概都是透過(手邊沒辦法實測，單純猜測)EBIX過去的..1G
