Software Defined Network (SDN) Implementation with POX Controller

While the idea of conceptually centralized network control is well accepted and understood throughout the SDN community, there are many alternative methods available for delivering such a perspective to several distributed controller instancesRe-policing is straightforward in SDN since the control plane and data plane are divided. Simply forwarding packets in line with the control plane’s established flow table rules is what network routers and switches do. OpenFlow, the most popular Software Defined Network protocol/standard at the present, has a list of design specifications. SDN/OpenFlow, albeit still a young field, has garnered significant interest from both academics and business. Large data centers are the outcome of an enormous volume of data. Large data centers typically have both virtual machines and virtual networks. Software defined network controllers are now a practical way to administer these network as a result. The research that has been done thus far on software define networks and openflow is summarised in this publication. With the use of mininet and the POX controller, Proposed method may be utilised to understand how to build a software-defined topology.
