Packet Cable defines a multimedia system architecture that overlays a high speed cable modem access network, with the goal of enabling, a wide variety of internet Protocol based multimedia services, such as voice over IP, unified messaging, video conferencing and on line gaming.This seminar begins with a brief summary of the developments made in the cable industry during the past years and then puts light on the core capabilities necessary to implement VoIP, online gaming etc. in a scalable fashion. This paper also explains the functional components needed in packet cable architecture and some possible next steps in the evolution of packet cable. Initially designed to support the time to market business considerations of North American cable operators, the Packet Cable architecture will continue to evolve to meet new business requirements and to accommodate advances resulting from the maturing of IP based technology. As new service requirements are identified, the architecture will also be extended to define additional capabilities to support these services. Packet Cable network is the promise for the future. It can provide cheap, high speed, easily accessible communication route even more efficiently in the coming years.
