IP MAN Technology And Application Of Differentiated Services Implementation

With the wide deployment and use of MPLS VPN in the metropolitan area network, this technology can satisfy the requirements from different users for real-time voice, video, data and other Internet services. This VPN network based on MPLS not only transfers private network VPN routing through the public road route and effectively isolates the VPN traffic, but also provides an effective guarantee for informatization of all enterprises and institutions. Thus, the method MPLS VPN network improves the differential Qos level of service becomes the focus of attention. Therefore, this paper will focus on MPLS Qos distinguishing model and MPLS traffic engineering.This paper, first of all, introduces the basic concept and principle of MPLS, the transmission process of MPLS VPN network VPNV4routing as well as the implementation of MBGP/MPLS VPN technology. Moreover, by analyzing and studying the Qos in MPLS VPN and traffic engineering, it proposes the MPLS differentiated services model in MPLS VPN network and the solution of DiffServ-aware traffic engineering implementation. Last but not least, according to the different network application environment and network bandwidth resources, MPLS DifferServ, MPLS-TE and DS-TE technology will be displayed periodically.Relying on the simulation network laboratory and combined with the metropolitan area network construction project, this paper optimizes MPLS VPN network deployment scheme. Starting with the different needs of the metropolitan existing NGN, VPN, Dedicated Internet and IPTV and other services to be undertaken in the future, taking the user’s subjective experience as the final goal, MPLS DifferServ and DiddServ-aware traffic engineering is displayed in this paper. According to the actual business application network, in the experimental environment, this paper designs three kinds of MPLS VPN Qos deployment scenarios, and analyzes the experimental data, provides an important basis for the next stage of Qos deployment in the metropolitan area network.
