Evaluation of Bandwidth Resource Allocation using Dynamic LSP and LDP in MPLS for Wireless Networks

Abstract

Fairness in bandwidth resource allocation is of high significance to the advancement in mobile and wireless technologies. It is likely that starvation of bandwidth due to some scheduling scheme would not be an appropriate option for the future development in the communication systems. However, there is need to consider an implementation that would lead to good network performance and avoid unguaranteed bandwidth delivery. This paper will be focusing on the evaluating performance of Bandwidth Allocation using Dynamic Label Switching Paths (LSPs) Tunnelling and Label Distribution Protocol (LDP) signaling in MPLS network. This will make provision for bandwidth allocation and reservation possible. An appropriate bandwidth allocation would have positive impact on throughput as well as the delay. It is an extension of the existing network model designed using network simulator. The results of an IP (Internet Protocol) Network without MPLS enabled is compared with MPLS model network. Furthermore, implementation of dynamic and static LSPs models are presented. In addition, there are models of bandwidth estimation, bandwidth allocation, delay and jitter. Therefore, performance metrics used in this respect are throughput, end-to-end delay and packet delay variation of the multimedia services (Voice and Video conferencing). These confirmed that the modified models have been improved as compared with the baseline.
