Software Defined Networking (SDN) - by A Harika

This is an article written by A Harika under her BTech Honors program (2016-18) The main objective of SDN (Software defined networking) is to decouple the control plane from the data and consolidating the control logic of devices into dedicated centralized control. One can leverage the features of SDN in finding the shortest path for the dynamically changing topology by extracting the topology information from the SDN controller through rest API's. Therefore the virtual machine migration in data centers becomes resilient for dynamically changing topologies. Workflow - Fig .1 Starting ODL Controller Fig. 2 . Creating topology and connecting to the ODL controller Fig. 3 Querying the topology using postman (REST API CLIENT) T he Northbound API's of SDN controller can be used to query the topology information. In this regard, one can use POSTMAN (REST API CLIENT) for the same. The follow ing GE...
