終於裝了!10M/2M-合勤 P873

[石之軒]

初裝機的時候,Actual Delay 是在7ms,
ping出去最低反應時間都在25ms以上.

後來經過某次的機房調整,Actual Delay 降到5ms
ping值最低也來到18ms.

vdsl能壓到個位數以下嗎？

vdsl能壓到個位數以下嗎？

我的20M跟10M浮動制最低是20ms~22ms左右..
vdsl企業固I的ping是10ms以下..光纖的3ms以下(ping hinet為例)
應該是集縮比問題吧..

但是有些網站下載東西,企業用的跑得還比浮動ip的慢咧
想不透到底為啥會這樣..莫非浮動ip一直都在掛影藏tp..
企業用的就真槍實料不走tp,所以會比較慢?

的確也是XD
看得到 吃不到...

前幾天再用 32~35ms之間
現在白天ping 是 27~29 左右..

使用VDSL1 Dlink DSL-5540C
線路14M的時候 14ms 因MOD HD開到25M 變19ms

家裡用2M/256K 用了5年多
前幾日合約終於到了...
一直想要換10M的機會終於到了....

不過 Actual Delay 好像稍微偏高
有辦法改善嗎....

請問樓主連到Router的電話線是哪一種是6P2C的扁線嗎？

還是那種兩條粗的銅線？我想應該也是計算錯誤？

話說回來我的Upstream Trellis Coding:是off

據家人描述,當天裝光纖時
改掉我家之前的ADSL配線
之後回來看新的配線
怎麼接我也看不太懂...

普通電話線,2條銅線的
是指這個嗎
Trellis Coding: ON ON
我的是開啟的...

小弟的Actual Delay跟樓主一樣,也是偏高
跑東西速度都不太穩定,不過數值看不太懂,貼上來請先進們解惑...

感覺你期待很久了
若都是用中華的
其實合約沒到也是可以升級
