Key Customers Based Mstp Network

In the current metropolitan area network, the data services are usuallyt provided with SDH and separatrd FR, ATM and the IP net. In fact, this kind of overlap network architecture is gradually formed with the development of the new services and advantageous to various service networks alone plan and the operation management. But with the increases of different type service quantity and the current capacity, specially high speed growth in the current IP service and diversification environment in the customer demand, this kind of network architecture creates the transmission network resource waste, the difficult network unified plan and the management, the complex among various service networks exchanges, the unavailable network development for the service diversification demand and so on. So the construction and the operation cost is more and more high, resulting in more and more difficult to meet the needs of the market development change.The metropolitan area network MSTP construction plan is one kind of present reality feasible metropolitan area network transition construction plan between the tradition "SDH+ATM" plan and the future entire light intelligence network. It is based on the existing SDH transmission network, but obviously advantageous to SDH. It has the compatible existing technology and the guarantee existing investment.This article first has carried on the analysis to the city territory transmission network,Next has analyzed the ether service thoroughly in the MSTP realization, the ether service and the ATM service in the MSTP realization and so on; MPLS to the load bearing level request unceasing enhancement which the detailed description in order to solve the user which to bring the handling ability insufficient question introduces in the technology, MSTP inlays the RPR technology; Then, to MSTP technology the application and the development direction have made the introduction, elaborated the use based on the SDH MSTP technology creation city territory load bearing network as well as the load bearing on this metropolitan area network key customer network application plan; Finally introduced based on the SDH MSTP equipment part test standard. The beacon-fire science and technology MSTP series equipment partial types which uses for the work in have specially made the brief structure and the function introduced that, its equipment connection rich, the network nimble characteristic has brought the unprecedented convenience for ours key customer network turning on and the network creation of our key customer.
