Broadcom design behind two CableHome certifications

Gateways from Linksys Inc. and NetGear Inc., each based on Broadcom Corp.'s BCM93348RG reference design, were certified by CableLabs as meeting the CableHome 1.0 specifications, which define designs for residential gateways with integrated router, security, and firewall functions. The gateways, based on Broadcom's hardware and CableMedea software, were certified in CableLabs' twenty-fourth round of certifications for DOCSIS and CableHome.

John Gleiter, director of marketing for Broadcom's broadband communication group, called the CableMedea software a key element to winning designs over high-volume home router manufacturers. The software is almost entirely homegrown, with small Wind River Systems adjuncts for network address translation. Broadcom developed its own Kerberos encryption-key software, Simple Network Management Protocol stack and stateful-inspection firewall software for CableMedea.

Even customers that have one or two of those software elements in-house have "adopted the full package for the ability to get to market quickly," Gleiter said.

Broadcom is now developing its first product suites for the CableHome 1.1 specifications, which add QoS functions to support voice telephony and video. Gleiter said he expects a rapid shift from CableHome 1.0 to 1.1 because cable multi-system operators are already preparing for "triple play" applications involving voice, data and video.

The latest round of CableLabs testing also saw Broadcom's TurboQAM BCM3348 DOCSIS architecture certified in 11 cable-modem products from eight OEMs, Broadcom said.
