Activity around PacketCable Multimedia (PCMM) remained high this spring following completion of a three-day interoperability event held at CableLabs' Louisville, Colo. facilities.
Building on DOCSIS, the PCMM architecture defines how cable networks provide guaranteed QoS for a variety of IP-based services and applications, including voice, gaming and video. It will also give cable the ability to participate in third-party revenue streams created by services such as Xbox Live. The PacketCable 1.x architecture, in comparison, is designed specifically to support carrier-class VoIP services.
CableLabs said eight suppliers participated in the non-certification event. ARRIS, Cisco Systems and Motorola Broadband supplied cable modem termination systems; Camiant, Telcordia and CableMatrix supplied policy servers; and Ellacoya, Syndeo Corp. and Telcordia provided application managers.
Camiant, one of a few startups spawned by PCMM, already has product in lab trials with Comcast and Cox.
Interoperability events are initial activities designed to see how well various devices from different vendors talk to each other and to determine if new technical requirements are required in the specification.
