Performance Analysis and Simulation of an Integrated Service TDM Ring Network
Zhu Xianjue Liu Zhengji
To provide integrated service on LAN a ring-net is examined in which the packet-switching and circuit-switching are combined.In this network Time Division Multiplexing(TDM)techniques are employed for transmis- sion and switching.Each TDM frame is divided into two fields:circuit- switching field and packet-switching field.The CS-field assigns channels according to users demand and provides real-time services(e.g.voice). The PS-field uses token passing protocol and provides nonreal-time servi- ces(e.g.data). This paper presents the perfomance analysis and computer simulation of this network.The behaviour in PS-feild is described by M/G/1 queuing system model and some evaluation formulas are derived with the help of the composite generating function method.The results obtained from theoretical analysis are coincident with computer simulation results approximately.
