Abstract

One of the main issues for offering end-to-end QoS in a network is how to select feasible paths that meet QoS requirements. In general, finding paths that meet QoS requirements is not an easy task and is called "QoS routing". The complexity of the networks that offer multimedia applications requires the consideration of multiple constraints for routing decision. This paper treats QoS routing problems in IP/MPLS networks using fuzzy logic. A number of different algorithms have been proposed for solving this problem. Most of these algorithms are not efficient because of their complexity and high cost. In this paper we propose Fuzzy QoS (FQOS) algorithm, for solving such a problem in MPLS network in Kosova. The performance of FQOS algorithm is evaluated using simulation and is compared to existing routing algorithm - CSPF.
