The Research And Realization Of QOS Route Model Based On The MPLS VPN

MPLS (multi- agreements label exchange technology) is at present sets up VPN one kind of essential technology, It for has provided the system structure strut based on IP QOS or COS. But, As a result of MPLS itself not inherent COS or the QOS characteristic, MPLS satisfies the need in particular by the dependence far is higher than the IP network, but until now the route system is not mature, The route system failure is difficult to analyze and the judgment, therefore, needs to improve MPLS VPN QOS and the route protects and restores the ability.Question exists which in view of present MPLS VPN, This article attempts to propose a more effective model overhead construction, And unifies the QOS route strategy and the algorithm, Carries on the consummation to the MPLS VPN performance.This article thoroughly is studying MPLS the basic principle of work, the letter makes the agreement and the QOS service system and the restraint route strategy and in the algorithm foundation, Proposed MPLS VPN strengthens QOS route model and detailed realization. The model MPLS and the Diff-serv integration is a body .Through has introduced special function BB in the model, Carries on the management and the monitoring to the VPN current capacity And in model foundation, Has constructed based on the discrimination service restraint route algorithm, Carries on the graduation and the classified management to the VPN current capacity Then, This article discussed the MPLS VPN way to protect and to restore the mechanism .In view of the vulnerable point which its exists has made the improvement .Finally, this article...
