The latest in the news other than Cyber Attacks, Obamacare and The Winter Olympics is SDN or Software Defined Networking.
What is SDN? Plus your chance to tell us what you see for SDN!
Well today’s networks are full of hardware and software with a bit of magic and lots of hard work we use the network to work through communications using applications.
The problem is that everything runs separately so if one device changes or crashes usually so does the network.
Today’s network is mainly made up on three planes
- The Data Plane (user, carrier, bearer..etc plane) – this is where the data is passed to the correct user or device, then we have
- The Control Plane – this is where routing and switching parts occur assuring that the packets are sent (controlled) to where they need to go, then
- The Management Plane – this is where the administration of things like logging, authentication…etc occur.
This flexible and programmable implementation allows for better network response to issues and increases the ability to better control or shape traffic and data flows. SDN helps by centralizing control and management allowing for better control and response to issues from failures to attack mitigation. The single controller format is easier to secure and update.
