What is OpenFlow?

OpenFlow is an open communications Protocol that acts on Layer 2 of the OSI Model and offers Access to the Forwarding aircraft of a Router or Switch over the Network. OpenFlow defiNitely lets in the path of inFormation Packets within the network of switches to be decided via Software Program this is running on at least two routers.

OpenFlow turned into designed for commUnity site visitors management among switches and routers of various models and from specific providers. OpenFlow separates the Programming of switches and routers from their Hardware so that no Hardware Configuration desires to be completed and all manipulate can be flexibly attained through Software program. The University of California Berkeley and Stanford University collaborated for 6 years before OpenFlow ultimately went Public in 2011.

What Does OpenFlow Mean?

There are 3 fundamental elements involved in this generation:

• Flow Tables, which can be Mounted inside the switches themselves
• A Controller, which communicates with the switches thru the OpenFlow protocol and units the policies on site visitors glide. It also units up unique paths thru the community or optimizes it for particular Attributes like pace, decreased Latency or wide Variety of hops.
• OpenFlow protocol, which enables the conTroller to safely speak with the switches

OpenFlow became created because vendors sell switches or routers with confined programmability, main to problems in traffic control and Engineering, as well as inconsistent traffic flows between Networking hardware from specific vendors. OpenFlow provides this Consistency with the aid of taking the manipulate far from hardware and imposing it with software program.
