A Tiling Approach for Multiple Parallel Routing in Software-Defined

Software-defined networking (SDN) is a form of computer network that simplifies the organization of data communications and provides an adaptive architecture that facilitates the transmission of large amounts of data. Previous researches have introduced different models for improving the centralized design of software-defined networks. However, the concept of multiple parallel routing has not leveraged the recent improvements in SDN. In this paper, we propose a multiple tiling technique that increases the application of parallel routing over the entire network. It aims to divide the network into several tiles such that each tile can independently employ parallel transmission based on its traffic status. Our main objective is to optimize bandwidth consumption and to improve load balancing performance. Our experimental results show that the proposed tiling approach improves the overall load balancing process, improve bandwidth usage, and therefore, reducing the chances of having traffic congestion.
