A Bandwidth Allocation Strategy for Video Communications Based on H.248 Protocol 基于H.248协议的视频通信带宽分配策略
The characteristics and topology of EPON system and the development situation of dynamic bandwidth allocation algorithm are introduced, as well as the structure of MPCP protocol which has an important role of in EPON system communication. 本文围绕EPON的拓扑结构特点以及MPCP协议的重要作用来展开研究,首先介绍了EPON系统的特点及其拓扑结构,动态带宽分配算法的发展现状和MPCP协议的结构及其在EPON系统通信中的作用。
This paper analyses that UDP flows will aroused the problems, or unfairness of bandwidth allocation and network congestion collapse, when UDP flows and TCP ( Transfer Control Protocol ) flows shared the same bottleneck link, and two kinds of schemes are proposed. 本文分析了当UDP数据流与TCP数据流共享同一瓶颈链路时,UDP流量会引发带宽占用的不公平性和网络拥塞崩溃的问题,并提出了解决方案。
Due to the demand-assigned MF-TDMA bandwidth allocation scheme, IPoS is able to support the reliable transmission service on data link layer, ensure the superior performance of throughput and delay, and effectively apply the TCP / IP protocol to the satellite link. 通过数据链路层的按需MF-TDMA带宽分配机制提供了可靠的传输服务,保证了系统良好的吞吐量特性和延时特性,有效的解决了TCP/IP协议在空间卫星网络上应用问题。
