Abstract

This paper presents performance analysis of high availability concept based on traffic segregation over Multi-Protocol Label Switching (MPLS) Traffic Engineering (TE). Recent years presents many deployment of Virtual Public Network (VPN) over Multi Protocol Label Switching (MPLS) network. This deployment benefits an organization or group of business for their own private network at a much lower costs compared to traditional point-to-point (P2P) private link. Hence, enterprise benefits from the VPN in reducing cost, increasing scalability and increasing productivity without costing the security of their network. Basic requirement of today systems on the design enterprise network is high availability. Deployment of high availability in load balancing and redundancy on existing service provider backbone network is still a challenging task. This paper presents ensured implementation on the network traffic. It immediately segregates and transparent to customer when the network edge device or access circuit was failures. Virtual Router Redundancy Protocol (VRRP) is configured to support high availability. Two gateways are provided at customer edge router, where one router elected as primary gateway, and another as a standby gateway. This situation presents the backup link which is not fully utilized. Traffic diversity concept is used where Policy Based Routing (PBR) handles the traffic segregation to utilize the traffic at both links. Results on analyzed implementation of high availability concept based on traffic segregation over MPLS-TE are presented.
