Research On Integration Of Local Area Communication System

Local area communication system provides transportation for data,voice and images in a certain area.It consists of PDS,LAN and real-time communication.Taking the communication system of Dow Corning(Zhang Jia Gang) Project PhaseⅠas an example,this thesis divides the system into three relative parts to show the concept of construction and modulization.Based on Cat.6 and fibers,PDS brings in Open Transport Network(OTN) to strengthen the stability and reliability of the system.With a particular description of VLAN division and IP projection,the thesis gives how distributed routing,access control and firewall can ensure the performance of the network.The system also uses soft switch to give a solution of real-time communication based on a custom IP Distributed Architecture(IPDA).
