| With the rapid development of internet nowadays, we're more inclined to depend on it in our daily life and in the exchange of information among companies and government offices. Under the influence of internet, the world has been connected into an integrated unity and transmission of information is no longer confined by time and space.As part of internet, IP metropolitan area network is an urban net within regional scale which provides various kinds of operation based on IP. From the perspective of application, each metropolitan area network is complicated due to its combination service of different accesses and businesses. Traditional technique of IP network is too simple, thus leading to challenges of its control, management, access, safety and reliability. As a result, we should reconstruct IP metropolitan area network, handle the uprising dangers by optimization and improve the quality of entire network of communications. Only in this way, the need of metropolitan area network can be met and service of higher quality and efficiency as well as greater satisfaction and advancement can be provided to customers.The thesis mainly introduces the key technology, network structure, model design and implementation plan related to MPLS VPN on the basis of its background and significance. The author maintains that with the fact that broadband added value business content ceaselessness enrich, the customer serving face to face a quality requirement, ceaselessness improves; therefore, it is necessary to optimize the network from both the economic and technological angles.Be to explain MPLS VPN concrete realization deploying in now available IP metropolitan area network, the author is tied in wedlock recent Tianjin business need, make use of the Cisco route implement to carry out the group net, the deployment scheme, simultaneous author having worked out one package IP MAN net MPLS VPN emphasize the plan and city region net having carried out VLAN among them , MPLS VPN IP address plan works. At present, the MPLS VPN deployment job is put into effect already in reality , the ceaseless improvement improves and perfects and according to future operation and new business need. |
