Abstract


The 21st century is an era of the core is information network, and it’s main features are digital, network and information. Railway information system is a very large and complex communicational system. The internal railway through the realization through the wan realize the interconnection of the national various areas. The main interconnection reflected in railway stations, railways, grass-roots. Even the remote small station can connected the internal railway. The construction and operation of the informational railway system provide very good network operation environment for the the overall implementation.Currently, the railway informatizational construction has entered the stage of rapid development. Due to the lack of unified development mode and planning, variety of information system exists in mush field, Different standard system constantly repeated investment construction. The results are low utilization and single function, even Unable to do the centralized management and professional maintenance.This design according to the customer requirement and the actual communication resources puts forward "railway data networks" integration solutions. Using the MPLS VPN technology to provide high-quality service network to the users and applied in the actual construction of railway informatization. The railway data networks’ development and implement with the important realistic significance, and pull railway market demand. and preemptive the "beachhead". The railway data networks has some advantages, such as low rent, safe and reliable. Due to the advanced technology and open standards can drastically reduce the terminal equipment and Access costs. Therefore, it has wide prospect of market.This paper first outline the network topology structure. Due to railway network access platform based on IP technology, there for install network routing device and DSLAM equipment on the base of the original railway sub-administration range. Secondly according to actual business networks of railway test results, made a thorough analysis and research and put forward the current railway private network technology.As is known to all.the safety is the most important event to railwav transportation.With the development of network information.railway and network are linked tightly.and it is one of the important tasks for railway informationizing construction to guarantee the network-railwav security. According to the safety of railway networks of existing problems, and put forward the corresponding optimization scheme.
