Deployment of SDN Based Openflow System and Related Network Topologies

摘要

Today's network switches require reconfigurations from time to time, as they have data forwarding plane and control plane positioned together in same devices. This results in complex working of switches, with inefficient performance in terms of repeated functionality and delayed delivery. This system based on SDN gives an idea to separate packet forwarding functionality from control functionality from such devices which results in efficient network communication. OpenFlow is one of the SDN technique provides network architectural paradigm to networking. By decoupling the control plane from data plane, SDN can achieve repolicing. Using OpenFlow, a network administrator can modify the nature of network by writing simple software programs, which manipulate the logical map of network. This system elaborates use of an OpenFlow switch in network with various topologies having single, multiple switches.
