Advanced Fuzzy Class-Based Routing in MPLS-TE Networks
Authors: ,
Abstract: The paper focuses on optimizing MPLS-TE networks using Constraint-Based Routing algorithm with implemented fuzzy logic. CBR includes routing algorithms that do not make routing decisions solely on the shortest path towards the destination but they can also base their decisions on various Quality of Service parameters or administrative needs. MPLS-TE networks can benefit from implementing such algorithms by utilizing less loaded paths or limiting the QoS parameters of the traffic to desired values. Implementing multiple constraints into algorithm can have issues with combining these constraints to make the decisions. Fuzzy logic represents an ideal tool for normalizing these constraints in [0,1] interval where the closer the constraint gets to 1, the better the path should be. The paper introduces a new CBR algorithm called Advanced Fuzzy Class Based Algorithm (AFCBA) which, besides setting the proper membership functions and cost calculations, deals with the tie break situations and what actions to take if no path satisfies the requirements of the traffic flows.
