HP confirmed its role as a leading light in the commercial availability of software defined networking (SDN)-based products at a New York launch event this week.
SDN aims to allow the users of network hardware to fully control their networks in the way they want, without being blocked by the proprietary controls traditionally contained in the expensive "black boxes" sold by the networking hardware vendors.
The Open Network Foundation (ONF) promoted the concept of software defined networking (SDN) at a NetEvents conference in Germany at the beginning of this year, and SDN was the hottest topic at a further NetEvents conference in the Algarve last week.
The ONF says SDN promises to efficiently automate network configuration, improve network performance and reduce total cost of ownership.
At the heart of SDN is OpenFlow, a communications protocol that gives access to the forwarding plane of a network switch or router over the network. OpenFlow allows the path of network packets through a network of switches to be determined by software running on a separate, basic and cheaper server.
This separation of the control from the forwarding allows for more sophisticated traffic management than what is feasible using access control lists (ACLs) and routing protocols, bypassing some of the more expensive proprietary software sold with networking hardware.
