QoS Security Mechanism and Improvement Strategies Based on MPLS Network

QoS is increasingly becoming one of the key indicators of the network performance measurement of next generation.This article deeply studied the MPLS-based network technology,the characteristics of the core technology,as well as two main QoS models for improving network——IntServ/RSVP and Diff-Serv based on the resources obligation.On this basis,it also discussed QoS security mechanism and improvement strategies based on MPLS network,as well as two main ways through the combination of DiffServ and MPLS to improve QoS and through MPLS-TE to make QoS better.
