SAN JOSE, Calif., April 10, 2013 /PRNewswire/ -- ADARA Networks®, a global software company in the software defined networking space, will release an open source controller, called SKY, to the market. ADARA made this announcement to coincide with a demonstration of select capabilities of its Software Defined Networking (SDN) product offering at Open Networking Summit 2013 in Santa Clara on April 15-17. The Open Networking Summit is the only nonprofit conference dedicated to accelerating the future of SDN technologies. "ADARA is very excited to announce its intent to release an industry first; a production quality open source controller," said Eric Johnson, Chairman and CEO of ADARA Networks. "The controllers currently available are either "free-ware" or "for-purchase." Current "free-ware" open source controllers are not production quality and the "for-purchase" controllers are limited, having been created for highly proprietary platforms as a way to lift declining sales of legacy infrastructure products; both of these are contrary to the intent of SDN." "ADARA is taking a step to move the vision of Open Networking and SDN forward; open source, production quality SDN solutions. Production quality means high performance, scalability, security and fault tolerance. The ADARA SKY Open Source SDN Controller is fully extensible, based upon and compatible with standards. Unlike current "for-purchase" controllers focused upon limited proprietary platforms, ADARA's SKY Open Source SDN Controller is engineered to elevate all networking infrastructure. Unlike current open source SDN offerings that consist of a "free-ware" version, which is only demonstration quality and "for- purchase" version, which is referred to as production quality, ADARA's SKY Open Source SDN Controller is both free and production ready. No one should have to pay for a production quality open source SDN controller and going forward they will never have to do so again," said Johnson.
