本文分析了计算机通信网中的一种新的混合交换技术。这种技术组合了电路交换、报文交换和报文分组交换,特点是网中某结点缓冲器内仅有一个报文分组时,新到达的信息就不必完全存储,在报文分组处理后即可直接输出,改善了网络延迟。这种交换称为部分一切通交换。本文研究了这种混合交换技术在网中按级联的M/G/1排队分析模型,而且所设各中间结点具有处理横向到达及离开的信息包能力。最后,采用事件调用方案编写了计算机模拟程序。数值分析与模拟曲线的结果表明,两者的一致性很好。
This article analyzes a new hybrid switching technology in computer communication networks. This technology combines circuit switching, packet switching and packet switching, characterized by a node in the network buffer has only one message packet, the newly arrived information does not have to be fully stored in the packet after the packet processing Can be directly output, improved network latency. This exchange is called partial exchange. In this paper, the M / G / 1 queuing analysis model of this hybrid switching technology in the network is studied, and each intermediate node has the ability to process the information packets arriving and departing laterally. Finally, a computer simulation program has been written using the event call scheme. Numerical analysis and simulation results show that the consistency between the two is good.
