Software Defined Networking (SDN)

  Software-Defined Networking or SDN is a relevant new term for an older paradigm of programmable networks. In summary SDN refers to the ability of writing applications to program the behavior of the network and the network devices.

SDN architecture

SDN framework

OpenFlow testbed

We have under development an OpenFlow testbed.

Current implementation

This is the current implementation of the testbed based on Openvswitch



Exposing the testbed for experimentation

The following image shows how the testbed is exposed for experimentation. The testbed is exposed via OpenLab tools (ie PTM, resource adapters and Teagle GW)


Open Distributed Network Element

An IP network element is composed of numerous logically separate entities that cooperate to provide a given functionality (such as a routing or IP switching) and yet appear as a normal integrated network element to external entities. Two primary types of network element components exist: control-plane components and forwarding-plane components.
