中文摘要 | 本計劃研發撥接埠管理系統(Dial-Up Port Administration System, DUPAS)的目的,主 要在於配合通用型交換機介面管理(Universal Switching Interface Management, USIM)系統的發 展。USIM系統成功的將交換機連上IP網路,讓資訊系統得以透過企業內部網路接取交換機, 讓所有資訊系統能夠分享交換機的有限資源,取代必須以專線連接的方式,但是,卻無法整 合已經上線且透過專線連接交換機的資訊系統,也無法讓機房人員所使用的終端機軟體連 接。DUPAS系統扮演一個中間者的角色。一方面,連接USIM系統,另一方面,提供撥接、 專線及直接電纜線連接等三種不同的方式,讓使用專線的資訊系統及機房人員所使用的終端 機軟體連接。此外,運用『以角色為基礎的存取控制(Role-Based Access control, RBAC)』理 論,作為交換機埠存取權限的管理機制,同時能線上監視並記錄每一個連線過程。在實際的 應用上,DUPAS系統可案裝在各個機房,也可以安裝在集中維運中心,目前,已在幾個地點 進行現場測試。 |
英文摘要 | The purpose of developing Dial-Up Port Administration System (DUPAS) is to help deploy Universal Switching Interface Management (USIM) system. It becomes possible to access the switches via intranet as USIM system connects the switches to the IP networks. But the USIM system fials to integrate the information systems that have to connect to switches via lease lines. Also, the USIM system provides no interface for the kinds of terminal software that are popular used to execute the operation jobs. So, DUPAS is developed to connect both sides. At one side, the DUPAS could connect USIM via the intranet, at the other side, the information systems could connect to DUPAS via lease lines and the kinds of terminal software could connect to DUPAS by direct cable connection or by remote dial. In additional, DUPAS uses the "Role-Based Access Control" mechanism to implement its access control policy, and have the ability to on-line monitor and log each communication session. For deployment issue, both site and operation management center (OMC) are good places to install DUPAS. At this time, we do the real trial of DUPAS system at some pre-chosen sites and OMC. |
