A Novel Approach of Traffic Management in Software Defined Networking Using Internal Controller

Abstract

The complex structure of the current computer networks causes problems in network scalability and management and makes it hard and time-consuming to implement general policies. A new architecture called Software Defined Network (SDN) has been developed to address these problems and challenges. One of the most important issues in SDNs is traffic engineering, which is a good criterion for network performance evaluation. After introducing SDNs and examining traffic engineering and its related challenges in SDN, this study presents two new multi-layer topologies for SDN which use their own customized and dedicated internal controllers to solve the traffic engineering challenge and manage the flow in the network by adding routing features to the switches. The results indicate more efficient management by reducing the delay, increasing the throughput, and ensuring higher accuracy in data transmission.
