本論文主要是探討在彈性封包環網路(RPR)環境下,加入有效率的訊務流頻寬排程機制,使得針對高優先權之封包訊務流,具有及時延遲的時間保證。最初,RPR網路採用CISCO公司所提出的RFC-2892的流量管理機制,此管理機制對於高優先權的封包來說,只有單純的提供頻寬大小,並沒有保證延遲的時間。因此,我們採用訊務流頻寬排程規則,找出排程傳送順序,使訊務流在傳送時,不僅可以保障高優先權訊務的時間延遲特性,並且符合服務等級契約(SLA-Service level argument)的要求,避免因為訊務流可能造成的碰撞而產生 packet train效應,此外,還能同時確保訊務流的頻寬能符合SLA 契約內容的條件。
In this thesis, the research aims that with the addition of effective flow and bandwidth schedule mechanism under the condition of RPR, the packet flow of high priority can be equipped with time guarantee on in-time-delay. Initially, RPR adopts the mechanism, RFC-2892, provided by CISCO company. As far as package with priority is concerned, the mechanism simply offers the space of Bandwidth rather than guarantee on delay. Therefore, we assume the principle of flow and bandwidth schedule to find transmission order. While the traffic flow is being transmitted, we ensure the characters of time delay of traffic flow as well as conform to the requirement of SLA-Service level argument, so that the packet train effect resulted from the collision of traffic flow could be avoided. Moreover, the Bandwidth of traffic flow can adhere to the condition of SLA as well.
