Data Network Planning Of The Lanzhou Railway Bureau

This paper aimed to integrated data network planning for the Lanzhou Railway Bureau. The development status and trends of Lanzhou Agency Network are analyzed, and finally the integrated data network construction planning for the Lanzhou Railway Bureau is discussed in details.Firstly, based on the analysis of the status quo of international and national railway information development, targeting at the current modernization and development of the domestic railway information building, combined with the high speed construction and electric construction of Lanzhou Railway Bureau, we need to integrate the redundant construction of the current bearer network and the low efficient use of resources, so as to fully utilize the abundant transmission resources of railway communication, as well as to embody the features of strong bearing business capacity, strong management and compatibility for backward network. In addition, the study gives a full consideration of the advancement, practicability, openness, reliability, plasticity, security, and other important properties. The study is able to meet the urgent need of the Railway Bureau to realize the information building in transportation and production, namely unified network construction of global Infrared Hotbox detection, remote power monitoring systems, video conference systems and vehicle service network video surveillance system. The study also points out the inevitable trend to build railway integrated broadband data network.Secondly, based on the system structure of Lanzhou Railway Bureau, the study analyzes Railway Administration bearer network networking, IP address planning, routing, MPLS VPN execution solutions and network security solutions embodiments. According to the need of Lanzhou Railway Bureau and the communication resources of the actual railway private network, in order to ensure the sustainable development of railway industry, the study proposes a special railway integrated data network solution. The solution makes use of MPLS and VPN technology to provide high-quality railway transport network bearer services, which provides a new construction mode for the development of railway informatization. It successfully solves the problems, such as large investment, maintenance difficulty and so on, when each service independently constructs its network in the information construction of Lanzhou Railway Bureau.Finally, through the analysis of Lanzhou Railway Bureau’s construction and implementation of the integrated data network, as well as the analysis of the core layer, convergence layer and access layer in the network with applications testing and the typical examples, the study illustrates the reasonable solution to dock different equipment, set up network and install equipment. At the same time, the study verifies the feasibility of utilizing MPLS and VPN networking technology, which indicating that it is a fully applicable technology for railway information network.
