The Study On SDH Applied To IP MAN

Recently among the development of China telecommunication industry, data business present a rapidest trend. The increase of customer amount and variety of user demand, specially the use of new business including of IPTV,VOIP,3G etc. do not only bring suppliers huge business opportunities, but also put forward a new challenge to the suppliers' network infrastructure and existing network construction idea. Currently the key problem what the IP network faces is whether the existing network can bear the high-speed growth of customer amount and the impact which the new business brought to the network higher request.MSTP (multi-protocol label switching) based on the SDH is the most mature technique among the MAN. So this paper emphasized on the study the optimized project of MSTP_based IP WAN, which is very important to maintain the image that suppliers build up for long time and hold the customer and increase the business.Firstly network structure and function request of delivering IP business on the SDH was provide. And it introduced two kinds of encapsulation technique including 6FP and LAPS on SDH and the Virtual Concatenation (VC) technology which makes use of transmission bandwidth efficiently and LCAS. Based on this theoretics, this paper emphasized study the transmission design of Ether net. Then the author analyzed testing target and the system performance, at last summarized the paper and prospected the development foreground of SDH and IP technique together in WAN.The topic made use of IP WAN optimized design in Chong qing and analyzed the actual network combined pipeline resources of the net and transmission resources, customer resources.etc in WAN, and studied the transmission system in Ether net based on SDH, in the end validated the testing to optimized WAN. Consequently this topic is practicability and advanced.
