A New Ethernet Switching Based on Extended Shortcut Switching Strategy

Spanning Tree Protocol is a layer-2 IEEE approved standard that provides a loop-free forwarding topology in Ethernet networks. In STP some links are active and the others are blocked. This guarantees only one route between each node pair. As in STP there is not any traffic engineering mechanism for load balancing, these results in uneven load distribution and bottlenecks especially close to the Root. In this paper we propose a new forwarding strategy based on using Shortcut Switching Strategy and hierarchical addressing and we will show we can achieve better results in comparison with STP.

In the Software Design Network (SDN), Control Plane and Data Plane are separated from each other [1], [2], so we can improve many of network parameters by using this advantage in control plane utilizing algorithms and applying the control policies. With improving the quality of these parameters, we can enhance the Quality of Service in a network. In this study, the aim is to carry out orders which are designed in Application Layer by programmer and provide for control layer and apply to switches by it. We can minimize the rate of Packet Loss with designing multi flow table and use Particle Swarm Optimization algorithm to find best network graph and consider the omission of the Loop in the network which contribute to reduce delay in the received packets and finally, raise Throughput and the Reliability and increase QOS, MININET Emulator and Pox controller were simulated and the results were compared with the previous networks.
