CATV的统计复用模型以及软件复用的具体实现

Statistical Multiplexing Model Based on the CATV Network and Implementation of Software-multiplexer

提出了一种基于CATV的统计复用模型 ,同以往的模型相比 ,这里通过设定自相关函数和相邻队列长度来确定分组和缓冲之间的关系 ,从而为复用器的设计奠定基础。同时利用这个模型的理论基础 ,在CATV网络上具体设计了一个基于软件复用的MPEG - 2传输流复用器 ,在实际的网络上的测试结果基本能够满足 8～ 1

This paper presents a statistical multiplexing model based on the CATV network. Compared with the proposes, this model determines the relation between the length of the packets with the I/O buffers by the autocorrelation functions and the adjacent queues, which settles the foundation for designing a multiplexer. This paper also proposes an implementation mode of software multiplexer on the CATV network with MPEG-2 transport stream by using this model. Eventually, the performance of the multiplexer is evaluated by the real time test.
