Watch out for Big Switch and its $25M!

Big Switch Networks flipped the switch on a second round of funding for its network virtualization technology.

Network virtualization is heating up. VMware acquired Nicira, a software-defined networking company, in July for $1.26 billion, and a startup called Plumgrid recently raised $10.7 million to develop its still-in-stealth mode network virtualization product.

Big Switch is another player in this field. The company’s OpenFlow platform makes network architecture more flexible by enabling multiple networks to act as one single network. This gives network administrators more control over the behavior of network devices, such as routers and switches.

VentureBeat sat down for a video interview with cofounder Kyle Forster last year to discuss the company and its technology, which you can watch here.

This round of $25 million came from Redpoint Ventures and Goldman Sachs, as well as from previous firms Index Ventures, Khosla and Ventures. Big Switch was founded in 2010 and has raised $39 million to date. Read the press release.
