The Proposal of Network System in Multi-Service Network Platform

摘要

This paper states infrastructure construction of IP network in broadband environment.rnFirst of all, I’d like to state the topology of a backbone network and access network,rnthere are only two types, and the other is Access Network. The leading role of thernpresent broadband access is fiber. Thereby, end user gets a new life style by triple playrnservices, such as data, VoIP, and Video Streaming on IP.rnAs one of the requirements required of NGN, the optical Ethernet access line of thernmetro area which is requires investment cost very much needs to attain commonrnnetwork with multi-service, and needs to hold down cost.rnHowever, also in an access network, requirements differ for every service to offer. If it isrnoffered for every service, it will require much cost. This solution technology of an accessrnnetwork platform which unifies multi-service are realized and proposed to this demand.
