一種動(dòng)態(tài)多播組成員管理策略的研究

在研究了多播組成員管理協(xié)議以及當(dāng)今多播路由協(xié)議的基礎(chǔ)上，依據(jù)延遲休假隊(duì)列模型
提出了一種新型動(dòng)態(tài)組管理策略。在一個(gè)網(wǎng)絡(luò)中，盡管在某一時(shí)間范圍內(nèi)一個(gè)特定的組成員數(shù)量為0 時(shí)，多播路由器不是簡(jiǎn)單地把該多播組從多播路由器中分離，而是采取一種智能的相關(guān)因子的方式?jīng)Q定多播路由器是否從特定的多播組中分離，從而可以減少在組成員維護(hù)時(shí)的代價(jià)。應(yīng)用隨機(jī)服務(wù)系統(tǒng)理論對(duì)該策略進(jìn)行了建模并進(jìn)行了理論分析。

Research on Dynamic Multicast Management Policy Mei Bing_Fu1, Li Yong_Jun 2 (1. Radio &Television Guangzhou University, Guangzhou, 510091 2. School of Computer Science & Engineering, South China University of Technology, Guangzhou, 510640) Abstract: Studying internet group management protocols and today’s multicast routing protocols, we propose a new strategy, which when the number of some multicast group is 0, the multicast router doesn’t simply separate the multicast group from itself and it adopts a intelligent factor which decide the multicast router to send prune information or not, if so, the multicast router will decrease the cost for managing the multicast group. In order to prove the strategy is efficient, Appling stochastic server system theory, we set up the model of the strategy and get a useful conclusion.
