SOFTWARE DEFINED NETWORKS SDN SIMULATION IN NS2
SOFTWARE DEFINED NETWORKS SDN SIMULATION IN NS2 Hi, Today we are going to have a look on software defined network simulation. Before that I will explain what a software defined network means? Software-defined networking ( SDN ) is an approach to computer networking that allows network administrators to manage network services through abstraction of lower-level functionality. SDN is meant to address the fact that the static architecture of traditional networks doesnt support the dynamic, scalable computing and storage needs of more modern computing environments such as data centers. This is done by decoupling or disassociating the system that makes decisions about where traffic is sent (the control plane) from the underlying systems that forward traffic to the selected destination (the data plane). SDN was commonly associated with the OpenFlow protocol (for remote communication with network plane elements for the pu...
