Changzhou, China Netcom Broadband Ip Man Structure Optimization

Changzhou Netcom as the mainstream telecommunications operator, in the past twogrowing number of broadband users. Broadband continued application of various types(PPPOE certification, NGN, IPTV, MPLS VPN).traditional core distribution accesslayer, the three-tier network structure has been unable to meet today's new requirementsAtpresent, the need for new planning and the transformation of existing networks to meetfuture development needs.According to business development needs and network development.Access layer willbe part of the three-tier network architecture from the traditional model of stripping accesslayer, the second layer to form an independent Access Network.unified planning.After there-planning will be composed of two parts: the Network backbone networks and MetroAccess Network.Among them, each part is divided into a number of sub-levels.Backbone network to provide broadband users end of the two-and three-VLANrouting transmitted from the core layer, layer pool,Access Control layer.Provide broadbandaccess network users access to the second floor.The target different users, Network Accessplane into large customers and the general user access planar two main parts.Access planeformed by the big green transmission ordinary user access and user access layer planegathered by the access layer.After the re-planning of the network structure is more clear, users can distinguishbetween major clients and the general servicesprovide more access business services(Intemet access, multicast, NGN, MPLS VPNs, QOS).provide safe, highly reliable, QoSmechanisms to provide redundant circuits for a range of users with better, faster.morereliable and flexible access to the Internet.
