Fuzzy Based Packet Scheduling Scheme using Non-Real Time Traffic in IP/MPLS Networks

Abstract

This paper presents Packets Processing Algorithm (PPA) in an Internet Protocol/Multiprotocol Label Switching (IP/MPLS) based networks. Mainly involved label distribution using Label Distribution Protocol and packet forwarding. Fuzzy based Packet Scheduling Algorithm (FPSA) would be incorporated with PPA in order to provide intelligent performance to the MPLS core networks. Previously, many research has been proposed on the MPLS Traffic Engineering. However, there is still a need to further research on MPLS simulator using different mechanisms such as the analytical model of MPLS, expert-based packet scheduling algorithm for MPLS QoS support. Since MPLS is not able to provide intelligent routing, it is necessary to propose an intelligent expert system of FPSA combined with PPA together with an analytical model of packet forwarding in the MPLS network. This will be able to justify the control of traffic congestion and reliable services. Furthermore, the network model created using NS2, which carries application such as File Transfer Protocol (FTP) will be used. Performance metrics of throughput and end-to-end delay are considered with the results obtained from trace files. Then, trace files are interpreted and used for the calculations of the aforementioned metrics by AWK script.
