Software-defined networking (SDN) received another vote of confidence today as Intel Capital, Intel's global investment and M&A organization, invested in Series B funding for Big Switch Networks, a developer of open software-defined networking. In total, Big Switch Networks has received more than $45 million from investors, including Goldman Sachs, Index Ventures, Khosla Ventures, Redpoint Ventures and others.

According to the company, cloud computing  is driving the convergence of server, storage, and network technologies, resulting in growing need for networking solutions that can support the dynamic nature of virtualized and Infrastructure-as-a-Service (IaaS) cloud data centers. To fulfill these needs, Big Switch Networks has developed its platform to enable network agility and cost-effective operations for cloud and enterprise scale-out data centers.

Intel Capital Managing Director Bryan Wolf acknowledged the emerging need for a platform of this magnitude. "Data center operators need programmable and cost effective merchant silicon-based networking architectures to meet their data center economic and operational objectives," Wolf said in a statement.

Back in 2012, Big Networks shipped an independent open software-defined networking suite, including network virtualization and network monitoring applications. The suite included network programability, flexibility, and various levels of network service delivery. To learn more about the suite, visit the company's website.
