Improving Load Balancing and Scalability by Implementing Path Selection on BGP Using Multi SD-WAN

Abstract

This research paper introduces three key problems relevant to data movement across the multi-domains. They are (1) delays in data transmission because of the failures of the links, (2) high throughput data transfer over large networks due to the worst path selection using the BGP, and (3) the efficient distribution of data (Load balancing and scalability). All three problems introduce scalability, load balancing and fail-over concerns with respect to the network architecture. The recent steps taken by SDN due to the introduction and popularity of OpenFlow provide a new way to approach these problems. This research paper proposes and demonstrates solutions to the aforementioned problems using scalable approaches introduced in SDN Controller. This research paper details the elements that influence BGP decisions on path selection using SDN infrastructure. Based on the features, a testbed using NS3 has been designed and implemented which explores ideas related to the domain-to-domain data transmission using SDN. The implementation of the Mesh topology of wires Domains was completed using NS3. This paper discusses also OpenFlow Service and the SDN involvement on BGP improvement over long-distance networks and the end users who wish to obtain the data in a timely manner with minimal effort.
