The results indicate that the packet loss probability of spc is the limit of spl and spn 結(jié)果表明: spc結(jié)構(gòu)的丟包率是spl和spn結(jié)構(gòu)丟包率的極限。
Theory analyse indicate that the mdf algorithm can get the minimum packet loss probability that is same with faa , and meanwhile it can greatly reduce the number of lrwcs 理論分析表明該算法在達到faa最小丟包率的同時能夠更好的節(jié)約波長轉(zhuǎn)換器的數(shù)目。
Aimed at the quality of service required by real - time service , an effective bandwidth calculating method for self - similar traffic is presented to provide guaranteed packet loss probability and maximum delay 摘要針對多媒體實時業(yè)務(wù)需要提供特定服務(wù)質(zhì)量的情況,給出了一種能夠同時保證分組丟失概率和最大延時的自相似業(yè)務(wù)等效帶寬計算方法。
Simulations confirm compared with faa , the mdf can save more lrwcs and fewer packet loss probability , especially in the condition of high load . using mdf algorithm , the number of lrwcs in the condition of high load is more than in the condition of low load when the packet loss rate approaches to a fixed value 通過仿真實驗驗證了該算法在低、中和高負載情況下,比faa算法更節(jié)約波長轉(zhuǎn)換器和更小的丟包率,而且在低負載時mdf算法的優(yōu)勢更加明顯。 mdf算法在高負載下,丟包率到達穩(wěn)定值所需要的lrwcs數(shù)目比低負載多。
In order to solve this problem , a reliable multica st communication model for conference control is designed specially . we firstly study the requirements of multicast - based conference control , then analysis the main factors to the performance of reliable multicast . subsequently we present a new reliable multicast protocol named hsrm ( hierarchical scalable and reliable multicast ) according to the receivers " packet loss probabilities 本文從分布式組播會議控制對網(wǎng)絡(luò)通信的要求出發(fā),在對影響可靠組播性能的因素進行深入分析基礎(chǔ)上,融合現(xiàn)有可靠組播協(xié)議的優(yōu)秀思想,提出了一個新的基于接收方丟失報文概率分組的層次化可擴展可靠組播通信模型hsrm ( hierarchicalscalablereliablemulticast ) 。
