PacketCable is an industry consortium founded by CableLabs with the goal of defining standards for the cable television modem access industry. CableLabs leads this initiative for interoperable interface specifications in order to deliver real-time multimedia services over two-way cable networks. Built on top of the industry’s DOCSIS (Data Over Cable Service Interface Specifications) cable modem infrastructure, PacketCable networks use the Internet Protocol (IP) to enable a wide range of multimedia services, such as Voice over IP (IP telephony), multimedia conferencing, interactive gaming, and general multimedia applications. A DOCSIS network with PacketCable extensions enables cable operators to deliver data and voice traffic efficiently using a single high-speed, quality-of-service (QoS)-enabled broadband (cable) architecture. The PacketCable effort dates back to 1997 when cable operators identified the need for a real-time multimedia architecture to support the delivery of advanced multimedia services over the DOCSIS architecture. The original PacketCable specifications were based on the physical network characteristics of operators in the U.S. For the European market, Cable Europe Labs, maintains a separate, but equivalent effort, ''EuroPacketCable'', based on European network implementations.〔http://www.cableeurope.eu/index.php?page=europacketcable EuroPacketCable industry website〕 ==Technical overview== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「PacketCable」の詳細全文を読む スポンサード リンク
