Models and algorithms of QoS-based routing with MPLS traffic engineering
5th IEEE International Conference on High Speed Networks and Multimedia Communication (Cat. No.02EX612) - Trang 128-132
Tóm tắt
MPLS QoS-based routing is tightly integrated to MPLS traffic engineering. Optimization objects and algorithms to select an optimized path in MPLS QoS-based routing are surveyed. Previous works based on weighted sum of cost and bandwidth, MIRA, PBR, etc. are discussed. By comparing the optimization goals of MIRA, such as MAX-MIN-MAX, WSUM-MAX and LEX-MAX, we present an improved model based on bandwidth prediction with the same inputs of MIRA. By analyzing the algorithms to get weighted graph and concepts of critical link and /spl Delta/-critical link, variable length /spl Delta/-critical link is presented to solve the problem of concentrator topology.
