| There are two factors driving the traditional transport network transforming to the All-Service transport network.One factor is that telecom bussiness operators are on the way of being all-service-providing operators.The other is that packet bussiness demands become main demands in the near future.The All-Service transport network defines an efficient, transparent and reliable network system which can achieve TDM and Packet convergence and trasmission all by itself. The object of the system is to achieve centralized management and rapid supply of network resources, to meet operation demands and ensure rapid recovery of failure. It plays a key role in the competition of telecom operators.At first,this article analyses the transport network development direction under the background of rapid growing packet-demand and All-ip trend.After full theoretical study of the techniques of OTN,ASON/GMPLS, the article proposes the functional research and implementation of this system based on Multiple technologies,which combines the advantages of two technologies.Secondly, this article focuses on the gloss structure design and implementation process.The methods of demand and technology analysis are sufficiently used including the methods of simulation model and lab experiments,implementation- evaluation.Lastly, all the results demonstrate that the design and implementation of Unified transport plane on OTN,unified control plane on ASON/GMPLS and unified network-management,is successful.The transport network will meet telecom bussiness operators demands and become powerful core competitiveness. |
