Urumqi Railway Bureau Dedicated Data Network Engineering Design

At present, the railway existing IP data networks, low independent existence network bandwidth, repetitive construction and waste of resources and so on many issues, have seriously restricted the railway informatization development process. In order to adapt to the requirements of the development of railway informatization, reasonable use of network resources, integrate various business, urgently need to urumqi railway administration special data networks built an efficient, intelligence, integration of network, therefore put forward the construction project of railway special data networks subject.Urumqi railway special data networks positioning in urumqi railway administration railway information network of bearing platform, is to overcome the railway5-ton business, video conference business, remote monitoring business, automatic office business in urgent need IP network load business and design construction. Its network, Internet with the physical isolation in business is to ensure that each business system accurately transmitting and security isolated, and to ensure that each business system controlled visits and difference between service. Using advanced and mature MPLS/VPN technology for the construction of urumqi railway administration special data networks provides an effective solution.This paper in order to satisfy the demand of urumqi railway special data networks, ensure realization business covers railway administrations, longitudinal and transverse business district, station, various departments at all levels of realizing interworking, information sharing, data exchange and business interaction goal. First introduced the construction of special data networks involving technical knowledge, second to related to the construction of railway special data networks demand, the paper analyzes the overall design scheme and goals. Finally, based on network system design, technical route selection, MPLS VPN deployment, routing design, IP address design and so on carries on the analysis and study of urumqi railway administration, constructed the network bearing platform special data networks overall design scheme, special data networks in railway administration after bearing platform plan, on the basis of building the characteristics of special data networks are analyzed and studied, completed equipment naming, respectively for IP address division, the deployment of MPLS VPN and at all levels of each layer protocol selection, etc, and eventually finished the design of railway special data networks task.
