我想問 一個問題關於一間公司擁有一個private network 既好處與壞處同一間公司租用ISP bandwidth 既好處與壞處
請問0係邊度可以搵到尼方面既資料?
謝謝

what do you mean by 公司有一個private network ?
Can you go out to the internet through your PRIVATE NETWORK ?

Don't really understand your questions. You need to be more specific.
" Private Network" means an isolated network not connecting to the internet ??? or a dedicated line directly connecting to the IX (Internet Exchange) ???
Otherwise cant help you.

我都唔係好明 your question.

你其實係咪想知道獨立專線 (Lease Line) 同埋普通 Always-on Broadband 之間有咩好與唔好之處 ?  

唔好意思各位
我想問既係自己有一條專線(own not hire by ISP) 同 hire ISP 既線既分別
最好有reference

Leased line, sometime called IPLC, sure can provide (almost) 100% security (since it should be physically port-to-port) and totally dedicated bandwidth. It is very expensive. Not many users are using it now since internet is getting so popular and cheap. Best referneces are the banks (connecting to their branches or interbank clearing), since they need maximum security. Jockey is are using IPLC linking all their betting shops, also for security reasons.

I think no need to explain internet connection IP-VPN ..........

真的謝謝你

我的case 就是bank
但有沒有那些參考的資料去支持那些論點?

elaborate more, IPLC means International Private Leased Circuit. All circuits cross different region will call IPLC, like Hong Kong to China.

you'll always need to have a private network at your locations.  Then you'll need to connect to Internet and/or other offices.  You may have the following choices.
1. Digital Datapak service in linking up two offices and not going thru' Internet.
2. Both location connect to Internet and set up a VPN link between them.
