Cloud Computing: Software-Defined Networking Rises Above The Hype
Grazed from InformationWeek. Author: Daniel P. Kent.
Over the last year, we’ve seen another technology phenomenon added to the long list of IT hype: software-defined networking (SDN). You might ask: "Haven’t networks been defined by software since the days of the ATM or the introduction of VLANs?" The answer is yes, there have been efforts to manage and manipulate physical network components through software, but most of these efforts have focused on easing network management tasks.
What makes SDN different is its intent to allow programmability of the network based on real-time information and data traffic flows. This allows for a closed-loop system where the network can be reconfigured to optimize applications or protect against threats dynamically, based on the current environment…


Open Invention Network (OIN) announced today that it has extended its Linux-protective network to include OpenStack and other cloud computing technologies. Specifically, it significantly expanded the technologies covered by OIN’s network of royalty-free cross-licenses and by its defensive patent portfolio. "Cloud computing’s flexibility and scalability are enabling previously unimagined innovation and value creation," said Keith Bergelt, CEO of Open Invention Network.
