Applied Research On Access Technology In Data Communication Of Municipal Administrative Service Center

With the development of the network,the existing interconnection network is difficult to adapt to the development of the modern network.For the construction of the existing network,it puts forward higher demand,which is mainly reflected in the network’s scalability,practicality,flexibility and so on.In this context,the virtual private network through the access to the Internet to establish a private network of tunnels and enterprise encryption of data communications remote access to a more and more recognition,that can reduce the network’s operation and maintenance costs,and more to force the business expansion of the enterprise.When handling multiple’s high speed connections,the extra overhead can also affect the routing performance.Due to the limited bandwidth,the router in the symmetrical digital subscriber line,ultra high speed digital subscriber line or private line,the network bandwidth can reach 60 to 70 Mbps or even higher,the impact on the router processing performance is obvious.The purpose of this paper is to solve the problem of access performance due to the large load of network equipment,which is based on the existing electronic monitoring system of Liaoning province(some area).The research process of the paper is to research and test the actual network requirements of a city administrative service center.In order to achieve the confidentiality requirements of design and application related content,the design content in this paper will hide the actual city information.By Dandong City Public Utilities Administrative Service Center,Dandong City Commission for Discipline Inspection soft environment office exchange,to now run network capture analysis,the active network efficiency analysis,combined with existing equipment,the actual situation of the server environment,after careful investigation,to lower the IPSEC encryption strength,transferred through NAT address mapping L2TP access location and other methods to reduce export router load and improve communication efficiency proved the practical value of the significance of the paper.
