The Research Into Applialication Of MPLS VPN Technology In DaQing Oil Field LAN

Daqing Oilfield LAN coverage of the Chinese Petroleum Corporation in Daqing in all units at all levels and their subordinate units, is in the oil part of a wide-area network. Daqing Oilfield LAN is a Huawei NE80E as the core, a 2.5G RPR double Ring structure of the core network. Bear the Daqing Oilfield Company Limited, Daqing Petroleum Administration Bureau, Daqing Petrochemical Corporation, Daqing Petrochemical Company and its subordinate units of the branch network access and the headquarters of the China Petroleum and communications tasks. Above all the subordinate units around the Daqing various regions, and access, are the nearest access to all core network nodes, leading to Daqing in the company's network all mixed together. With the development of information technology, the gradual application of information technology in-depth, how to efficiently integrate the various branches of the company's network, and physical entities in a number of Internet companies operating the logic of proprietary network of Daqing Oilfield has become an urgent need to resolve the LAN A problem. MPLS VPN technology is the large, complex network construction in an important direction of the applied research. This paper describes the evolution of the development of VPN technology, in-depth analysis of the principle of MPLS technology, summed up the MPLS VPN in the network of private, and service quality assurance which is a clear technological superiority. Analysis of the MPLS network structure and architecture of the main components and core technology, MPLS work processes were discussed; analysis of the Daqing oilfield in the local area network under the company's various business communications needs. The Daqing Oilfield LAN MPLS VPN to do a detailed planning and design, research MPLS VPN environment of the Daqing Oilfield LAN RD / RT planning, routing protocols and routing strategy, QOS guarantees and the corresponding mutual relations and MPLS VPN Network management tools and methods were discussed. And the application of this design will be in Daqing Oilfield in a local area network applications. Daqing Oilfield MPLS VPN LAN implementation of the results achieved in various branches of the company's goal of the network, a LAN use of Daqing Oilfield MPLS VPN classic case of technology for future large-scale, complex network of integrated network of the implementation of the project to provide a certain And promote the value of reference.
