中文摘要 | 中華電信北區Intranet ATM網路自86年11月建設以來,已有多項業務透過此網路來提供服務。由於ATM LAN設備的高可靠度以及擁有一套有效的維護程序,北區Intranet一直提供相當不錯的網路服務品質,但其缺點是沒有備援的設計。為了彌補此一缺失,進一步提高網路可用度,特別改變北區Intranet骨幹網路的架構,使之具有備援的能力,不會因網路設備故障而導致服務中斷。本文即是針對備援網路架構之可用度作一探討,以期能提供適當的評估模式,了解備援架構對網路可用度的改善實效,作為後續網路品質提昇之依據。 |
英文摘要 | The Intranet (CHTN) of Nothern Taiwan Business Group is an ATM based broadband network deployed since November 1997. There are many business applications supported by it. The Intranet uses highly reliable ATM LAN devices and a suit of effective maintenance procedure. As a result, the CHTN Intranet provides satisfactory quality of service all the time. But the disadvantage is that it was designed without redundant conside4ration. In order to make it up for this disadvantage and enhance the availability of the network further, we redesign the architecture of the CHTN Intranet backbone network to make it have the capability of redundancy so that it will not disrupt the services in case any of the devices fails. This article discusses the availability of the redundant network. We provide an appropriate evaluating model as a basis for improving the quality of the Intranet. |
