BNI VideoNetwork giant Cisco has acquired video optimization software company BNI Video for $99 million in cash, the company announced today.

BNI Video helps Internet service providers manage their video services, including entitlement, billing and quality control. As VentureBeat previously reported, BNI Video offered a good solution for older cable providers unable to keep up with the growing trend of TV moving online.

Cisco said it plans to integrate BNI Video’s technology with its Videoscape service, which will make it useful for service providers that are beginning to deliver more video over the Internet to consumers.

BNI Video is one of many companies Cisco has purchased to strengthen Videoscape. In August 2010, the network equipment company acquired online video distributor ExtendMedia to enhance its video-over-IP capabilities. And in February, Cisco purchased Inlet Technologies to boost Videoscape’s video encoding abilities.

Founded in 2009, the Boxborough, Mass.-based startup previously raised a total of $16 million in funding from Cisco Systems, Comcast Interactive Capital, Time Warner Investments, Charles River Ventures and Castile Ventures. Cisco is scheduled to close its acquisition of BNI Video in January 2012.
