QOS Research Based On MPLS-VPN Of Telecom Provider

Along with the Internet popularization and the development, caused people's widespread attention,MPLS VPN based on the MPLS hypothesized special-purpose net technology to be able to use the public backbone network widespread and the formidable through-put capacity, reduced enterprise interior network /Internet the construction cost, enormously enhanced the user network operation and the management flexibility, simultaneously could satisfy the user to the intelligence transmission security, timely, wideband, the convenience need, therefore received some large-scale cross region group users very much the welcome.The service quality of MPLS VPN is highly affected by its low layer network, the IP network, which has the nature of transmission delay, jitter and packet loss rate.Furthermor,customers request for network redundancy incase of any failture,and differentiated services,Theremore, it is vital for the successful launch of this service that we could provide end-to-end service quality between headquarter and branehes or among branches.Along with communication rapid development, the people solved QoS to the next generation network to fill the anticipation. The people hoped provides must satisfy fast for user's clothing, is stable, the reliability, the validity, the multiplicity, the flexibility contour quality requirement. How but in the service stratification plane service requested uses the standard the agreement to transmit the QOS rank, how the load bearing stratification plane mixes the question according to the service rank which the reasonable network resources still was is worth exploring.This article is precisely based on uses MPLS VPN the technical network T operation business, how realizes the research in the network which the QoSability launches.
