In an OpenFlow network, the various control plane functions of an L2 switch — Spanning Tree Protocol, MAC address learning, etc. — are determined by server software rather than switch firmware.

OpenFlow switches are configurable via the OpenFlow API, and also have an MPLS extension for quality-of-service and service-level-agreement support. By extending these capabilities to ns-3 for a ...

In an OpenFlow network, the various control plane functions of an L2 switch — Spanning Tree Protocol, MAC address learning, etc. — are determined by server software rather than switch firmware.

Controllers talk to the switches via the OpenFlow protocol and impose policies on flows. The controller could set up paths through the network optimized for specific characteristics, such as speed ...

An SDN research paper points toward what could become OpenFlow 2.0, a protocol that's given more leeway for changing the underlying switches.

The protocol designers may not have even considered this a vulnerability in February 2011 when OpenFlow Version 1.0 was published, because exploitation does require an attacker to attach a maliciously ...

The combination of open source software and commodity hardware holds the potential for unprecedented efficiency and operational agility but, despite the success of Web-scale giants like Google and Fac ...

Similar to a real OpenFlow switch, a GPON virtual switch can be controlled by a standard OpenFlow controller. In our design, an embedded OpenFlow agent resides in the optical line termination (OLT) of ...
