多点多业务等级电视会议网模型与性能分析

Traffic Model and Performance Analysis for Multi -point and Multi class Teleconferencing Networks

摘要: 研究多点多级电视会议网络的业务模型及性能分析。采用knapsack模型分析网络的呼叫阻塞概率。在此模型中,假设网络能提供多级视频信号质量。业务模型用于研究网络结构及线路规模要求。主要考虑了星型网。给出了一个分析实例。

Abstract: In this paper,the traffic model and the performance analysis for multi-point and multi-class teleconferencing network are studied.The knapsack model is used to analyze the blocking probability performance of the teleconferencing networks.In the teleconferencing traffic model,an array of video services ranging from lower to higher quality is assumed.The star network topology is considered in this paper.An illustrative example is provided.
