Service-aware LSP selection with fuzzy based packet scheduling scheme for non - real time traffics

Abstract

An essential solution is available in Multi-Protocol Label Switching (MPLS), which proffers certain solution to the problems faced in networks of today in terms of bandwidth management, quality-of-service (QoS) availability, and traffic control. This paper is an extension of work on Fuzzy based Packet Scheduling Algorithm (FPSA) combined with Packets Processing Algorithm (PPA) in an Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) networks. This will make provision for an intelligent service to the Label Switched Path (LSP) in MPLS networks. Several research work have been proposed on the MPLS Traffic Engineering. However, it is still imperative to further research on the effect of bandwidth increment on the core network using different mechanisms such as the analytical model of MPLS, expertbased packet scheduling algorithm for MPLS QoS support. Since MPLS do not have provision for intelligent routing, it is necessary to propose an intelligent expert system of FPSA combined with PPA. And analytical model of packet forwarding in the MPLS network would be given to provide suitable solution to traffic congestion and reliable services. Furthermore, the network model created using Network Simulator (NS 2), which carries nonreal time application such as File Transfer Protocol (FTP) with bandwidth variations. The results obtained from trace files are interpreted by AWK script and used for the further analysis. The research on FPSA is necessary based on making the decision for the selection of satisfactory service, whereby solving problem of underutilization and overutilization on the links. However, fuzzy lacks the provision for solving complexity of multiple input parameters.
