But till now , the stability of system , especially the oscillations of buffer occupancy have not been the focus of research in congestion control 但目前在擁塞控制方面的研究對于網絡節點的緩沖占有量的抖動性即系統穩定性考慮不多。
With regard to the flow regulation of the best - effort traffic , the controllable traffic in high speed computer communication networks , the present paper proposes a novel control theoretic approach that designs a proportional - integrative ( pi ) controller based on multi - rate sampling for congestion controlling . based on the traffic model of a single node and on system stability criterion , it is shown that this pi controller can regulate the source rate on the basis of the knowledge of buffer occupancy of the destination node in such a manner that the congestion - controlled network is asymptotically stable without oscillation in terms of the buffer occupancy of the destionation node ; and the steady value of queue length is consistent with the specified threshold value 本文從控制理論的角度出發,針對計算機高速互聯網中最大服務交通流即能控交通流的調節問題提出了一種基于多速率采樣的具有比例積分( pi )控制器結構的擁塞控制理論和方法,在單個節點的交通流的模型基礎上,運用控制理論中的系統穩定性分析方法,討論如何利用信終端節點緩沖占有量的比例加積分的反饋形式來調節信源節點的能控交通流的輸入速率,從而使被控網絡節點的緩沖占有量趨于穩定;同時使被控網絡節點的穩定隊列長度逼近指定的門限值。
Using modern control theory and method , we show how the controller can regulate the source rate on the basis of the knowledge of buffer occupancy of the destination node in such a manner that the rate of source node is stable , and the congestion controlled network is asymptotically stable without oscillation in terms of the buffer occupancy of the destination node 并且運用現代控制理論和方法,討論如何利用基于組播的單速率擁塞控制方法來對組播篡碩士學位論文mas ; ter ’ 5thesis發送節點的發送速率進行調節,從而使得發送節點的發送速率和接收節點的緩沖占有量均趨于穩定。
