292 Providing Enhanced Nextgen VoIP Service Using Packetcable Network with Efficient QoS

PacketCable networks use Internet protocol (IP) technology to enable a wide range of multimedia services, such as IP telephony, multimedia conferencing, interactive gaming, and general multimedia applications. Packet Cable defines an IP-based service delivery architecture that overlays the the Data over Cable Service Interface Specification (DOCSIS 1.1) infrastructure. While Voice over IP (VoIP) is the first service considered for the PacketCable platform, a wide variety of beyond-voice services will also be supported, including services such as unified messaging, interactive gaming, and videoconferencing. The end-to- end architecture as designed, offers a complete system that includes: provisioning, signaling, event messaging, configuration management, quality of service (QoS), media transfer and security. These functions are managed by specific servers and network endpoints that when combined, collectively build a PacketCable network. This paper is centred on what it takes to build a PacketCable network, with a focus on the variety of headend servers that manage all aspects of service delivery for on-net as well as off-net IP sessions. It will also profile the architecture designed for event messages and concludes with short description of Integration of Gstreamer Library for effective QoS for media transfer across the network.
