The Optimization Scheme Design And Engineering Practice Of Ningxia Telecom IP Networks

Along with the computer network technology's swift development, the IP technological development into leadership technology, is getting more and more rich based on the INTERNET application, user's correspondence demand from the traditional narrow band telephone, the facsimile, the narrow band data and so on gradually to broadband business domains and so on high speed data, pronunciation, image as well as multimedia integrations extends.he telecommunication service was unceasingly rich and the telecommunication networking development, high-end user MPLS the VPN service, the high-end special line turning on service, NGN,3G, VNET and the similar important application service proposed the high QOS safeguard and the high secure request to the Ningxia telecommunication IP metropolitan area network, therefore the wide band metropolitan area network's network optimization appeared important especially.Because the information class service is different with traditional Internet turning on, it to the network grade of service, secure and so on has the very high request, to complete service reforming, and the guarantee network may transform smoothly adapts the new service demand, constructs the high QOS safeguard and the high secure high-quality goods network, sets up the brand image, will realize high-end user's service turning on, the Ningxia telecommunication in the entire district IP metropolitan area network will deploy that the SR service router and the service switching equipment, will realize to the different service QOS safeguard.The present paper key carries on the design to the Ningxia telecommunication IP metropolitan area network network optimization plan, an installation work stage to the Yinchuan SR service router and the gathering switching equipment to give the exhaustive design notes.The present paper key carries on the design to the Ningxia telecommunication IP metropolitan area network network optimization plan, an installation work stage to the Yinchuan SR service router and the gathering switching equipment to give the exhaustive design notes.Ningxia telecom IP networks optimization design mainly include the following aspects: First, consult about IP networks, learning IP networks optimizing information system structure, IP network includes network platform and service platform. Learning about the IP networks, the network topology of network security strategy, and application of technology management, VLAN charging ways of management, and the business of authentication.Field to field collection of ningxia IP networks, the network structure of present situation, business access IP networks of ningxia analyses existing problems in ningxia, according to "IP networks planning and implementation plan" in deploying the IP networks yinchuan, enhance the reliability, expansibility and bearing capacity and improve the network safe and tolerant ability, network adjustment, the goals and objectives, floor and business planning and carrying three layers of VPN, IP address and VLAN resources. Formulate IGB BGP and design, using hierarchical routing, ensure the district in the afternoon QOS of the entire network end-to-end QOS guarantee mechanism, with three layer by layer QOS QOS combination of deploying respectively established access equipment QOS deployment strategy and metropolitan equipment QOS deployment strategy. In order to adapt to business, IP multicast networks multicast planning. Through various comprehensive consideration, established in ningxia IP networks optimization schemeIn ningxia IP networks optimization scheme implementation, increased 7450ESS6 21 sets, placed in the west, the east, with two long, xincheng, inner, Chen village, nan, beiyuan, LingWu, HeLan, yongning, the bureau of 12 ningdong room as business access switches.4 7750 separately placed in enterprise, with two long, west, inner four nodes, four devices using 2.5g POS port construction ring structure, ring net weight in FRR MPLS do fast route protection. Enterprise and the west two nodes 7750 by GE port to the double 12416B and even two GSR12416A yinchuan, each end of the bureau 7450 equipment by GE circuit interconnection between. On the 7750 equipment and runs nearby BRAS equipment.The paper obtains the main achievement was has further enriched the Ningxia telecommunication IP metropolitan area network and the IP Internet technology development theoretically, has accelerated the Ningxia telecommunication wide band Internet network construction process through the science optimization plan, further helped the enterprise to improve the wide band network quality and to enhance the telecommunication in the Internet time competitive ability.
