Abstract
In order to improve network performance, traffic management is imperative. In addition to increasing the volume of network data, software-defined networks have expanded and the amount of information exchanged between the data plane and the control plane has increased. This will lead to congestion and reduce network efficiency because more traffic will flow through these networks. Congestion in these networks can be controlled effectively with switch migration. A mechanism that provides congestion control through the virtual migration of switches is presented, known as Virtual Network Request Load Balancing Profit (VNR_LBP). It is a problem to have many requests at a switch node, and to solve it, there is an effective solution. Network virtualization allows the controller to migrate switches into this space by taking advantage of available resources in switches and links. In order to control congestion, we have calculated the profit function of nodes and links to determine how much congestion exists. We also request a virtual network (VNR) to reduce load and manage resources. Lastly, the proposed method was evaluated using NS2 simulator according to various criteria. Simulated results show that in comparison with the basic method, the proposed method increases throughput by about 4.3%, decreases delay by about 5.3%, and reduces the average cost by 26%.
