Enforcement of Policy Rules in Software Defined Network using Openflow
Abstract
the existing networking devices (switches) are complex because they have control plane and data forwarding plane interwined in same devices. This affects the network performance in terms of delayed delivery and repeated functionality. The proposed network software system gives the technique to separate control functionality from the forwarding functionality from such devices which results in efficient network communication. OpenFlow, one of the technique of Software Defined Network Technology, is a new approach to networking and its key attribute is: separation of data and control planes. With OpenFlow, a researcher or network administrator can introduce a new capability by writing a simple software program that manipulates the logical map of a slice of the network. The rest is taken care by the network operating system.
