中文拼音 [yōngsèbīndài]
擁塞頻帶
英文
crowded band-
Secondly, the author analyzes adaptive encoding control algorithm, pack algorithm and feedback congestion control algorithm suited to mpeg - 4 video. taking into account the matching transport rate and bandwidth, the author gives an improvement and optimization of the feedback congestion control algorithm. finally, a feasible project of network visual telephone is designed
其次，在視頻數據的傳輸碼率與網路帶寬的適應性方面，作者通過分析適用於mpeg - 4視頻適應性編碼的控制演算法、視頻數據打包演算法和網路擁塞控制演算法，提出了網路擁塞反饋控制演算法的改進和優化思想。The experimental results show that the mechanism can achieve the tcp - friendly behavior and the smooth variation of video quality while the network bandwidth varies
實驗結果表明該擁塞控制機制能夠實現一定的tcp友好性，並且能夠保證視頻質量隨著網路帶寬的波動而平穩地變化。Mblue works with an fifo queue without assumptions about queuing architecture. through little state information of each flow mblue achieves fair bandwidth allocation among flows sharing the bottle - neck. simulation results demonstrate the fairness of mblue
Mblue使用數據報丟棄的頻率和隊列空閑程度來管理網路擁塞；它只維護一個先進先出隊列，以較少的數據流狀態信息，在不同流之間公平地分配網路帶寬。We chose suitable tcp throughput model to estimate the available bandwidth correctly, using the estimated round trip time and packet loss ratio for the next time interval as parameters of the model to achive the accuracy of estimated network bandwidth. as the observed losses and round trip time vary very dynamically, adjust the sending rate equivalent to the amount of tcp throughput may result in a rather fluctuant sending rate. so we present a rate adjustment like tcp congestion control based on aimd, which increases its sending rate by an additive inereease rate
根據mpeg4視頻流應用的特點，選擇合適的吞吐量模型，進行合理的參數估計，並根據計算出的帶寬進行相應的速率調整來實現擁塞控制，我們使用未來rtt的估計值和分組丟失率的估計值作為吞吐量模型的參數，增強了控制的實時性，弱化了業務的振蕩性，提高了帶寬預測的準確性；在進行速率調整時，不是簡單地將發送速率調整到與tcp吞吐量模型一致，而是採用類似tcp的aimd策略來調節發送速率，減小了發送速率的振蕩性。In this paper, the streaming media technology applied to network video monitor system are researched on the basis of video streaming. the emphases are put on system design, video captures and play, and the design of network transmission module and relevant software development method. in fact, uality of service of the network has unstable characteristics, we have analyzed qos guarantee strategy in video streaming transmission on network, and presents a integrated qos guarantee scheme which based on data encapsulation, buffer storage technology and congestion control on network. this scheme do its best to avoid the big delay or congestion on network based on make full use of network bandwidth, which can guarantee the best qos of the video transmission
重點討論了系統架構、視頻捕獲和播放、網路傳輸模塊設計以及相關軟體開發方法。同時，針對實際網路中存在的服務不穩定性特點，分析了視頻流在網路傳輸過程中的qos保證技術，並在系統中提出了基於數據封裝、緩存技術以及網路擁塞控制機制的綜合qos解決方案。該方案使系統在充分利用網路帶寬的情況下最大程度上避免出現大的延遲或擁塞，保證了視頻傳輸的最佳服務質量。分享友人
