Design On Constraint-Route Traffic-Engineering Design Based On MPLS

With continuous increment of primary dynamic network users and transmission, increasingly comes up primary dynamic network resource being lack and network block problem, and with new network business mode presenting, brings up new requirement to quality of service network (QoS). Transmission engineering is come up for solving these problems. Dynamic network can whole be expected to solve disadvantage of primary dynamic network in the next generation network. Through optimizing network resource use, achieves the purpose for reducing network block and improving network capability. The Multiprotocol Label Switching(MPLS) technology is well known as the best tool for achieving transmission engineering at present.Main innovation and research conclusion of this paper:In this paper we mainly research how to achieve transmission engineering in MPLS network, and emphasize to compare several route protocol, and find out a sort of channel bandwidth to fit dynamic network, quick network deployment, dynamic networking, route protocol for high anti-destroyed design. Irrationality of network resources distribution may cause error and network capability become worsen much more, and cause congestion. Therefore, This article mainly explain how to utilize network resource from selecting route protocol this view, and through rationally distributing network resources to achieve networking capability.(1) Bring up a sort of distributed control route methodology achieving transmission engineering in dynamic network. The methodology collects network information with expanded inner gateway protocol, gets display route with optimize arithmetic. The methodology adopts delay and bandwidth for control condition, achieved simply, satisfies requirement of dynamic networking, and avoids wasting network resource in route process transmission mechanism. Through simulation and practice experiment in dynamic network one year, The methodology is effective and active to solve multipriority and dynamic network topology continually changing.(2) The paper make a result, changing network communication mode. It achieves integrating with command and automatic system, provides guarantee for achieving a integrated information platform. It provides integrated communication means for their cooperation operation, improves dynamic network environment transparence, information share, real time and control precision.
