With SDN, your networks are application aware, optimizing performance across the entire DC network and campus LAN. Now that's teamwork.

A strategy for improving performance, management and security

What is Software Defined Networking? It's is the term used to refer to the many approaches proposed by standards bodies and network vendor communities to solve this problem.

SDN aims to provide a coordinated virtual infrastructure where applications and the network can collaborate for a high quality user experience and optimized resource consumption.

SDN doesn’t have to mean that we forget everything we have, but rather use it in a better, more efficient manner than ever before.

The principles of SDN:

  • Programmability: Links can be made between the application control and network control layers to optimize application performance and increase visibility
  • Application Awareness: The network can automatically react to the dynamic requirements of virtualized workloads, for example moving resources in the data center to unleash the workload optimization capabilities now available for computing
  • Global Control View: Network control systems have a global view of current network conditions to improve local decisions made by individual network nodes on how to treat traffic streams of a particular application
