Concurrent Multi-path Transfer extension of the Stream Control Transport Protocol (CMT-SCTP) has great potential to improve the utilization of scarce network bandwidth resource. Traditional CMT-SCTP adopts Round Robin (RR) algorithms to carry out packet scheduling that could affect the performance of SCTP traffic as unordered issues. In this paper, we discuss the unordered issues and propose a novel packet scheduling algorithm to improve the performance in heterogeneous wireless network. Our main idea is predicting the packet arriving time and then provides a path selection strategy. Through measuring round-trip time (RTT) and available bandwidth, we achieve an algorithm to predict the arriving time of data packets on one path, then give a reasonable path selection strategy to make sure that data arrives in the right order. By using proposed algorithm, the unordered packets and receive buffer blocking are reduced. We evaluate the performance of our algorithm by comparing it with the RR algorithm and show that it can resolve several performance issues.

Multi Protocol Label Switching

An essential solution is available in Multi-protocol label switching (MPLS), which solve the problems faced by present-day networks: speed, scalability, quality-of-service (QoS) management, and traffic engineering. 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, 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. 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 non-real 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.
