【急】功課問題

條問題係咁:
香港和台灣的距離，比香港和美國的距離遠，但為何在一般情況下在香港下載台灣網站資料時間比下載美國網站資料的時間長？？？


有冇人可以知點解．．．．

啫係點丫？

因為......
好多network公司都在hk<->usa之間架有專線
所以data transfers較快較直接
但去台灣...則冇咁多專線
而且亞洲有不少data都係經hk去tw
所以都有一定既network jam
so慢

T3 專線

Traffic is the key
Between HK-USA there are many T3(Very Board Band )line across.  Acually, hong kong is the major landing for most lease line across pacific ocean.  That is also the reason why phoning IDD to USA is a lot cheaper than other asia country.

Also, your ISP may proxy some of the more popular site (like yahoo).
So when you go to the site, what you get is actually a copy of the site that sit inside your ISP's network.

All ISPs use proxies(transparent ones)... but I do not think this is the answer. The previous answer(more links with greater bandwidth between USA and HK) is the key.

因為台灣係要經外國proxy

可能ISP的國外專線無TW份, 去TW 0既就要先經USA (for example), 咁會令去USA0既Transport比去TW0既快(以前上大陸網慢就係呢個緣故, 無Direct Connection)<--Secnerio 1
又可能去TW條線的Bandwidth不如去USA果條, 如果Connections 一樣, 去美國梗快過去台灣了 <-- Secnerio 2

Hope can help
