A common IP layer client device interface within an IP multimedia gateway (IMG) is configured to connect client devices to broadband IP networks such as the Internet based on determined device capabilities. Broadband IP network interfaces within the IMG are configured to enable communication between the IMG and broadband IP networks based on the determined device capabilities. Content provided by various service managers are communicated with the client devices utilizing the common IP layer client device interface and the configured network interfaces. Network capabilities may be determined during the device and network discovery. Protocol translation, media transcoding and/or dynamic device configuration may be performed based on the determined device capabilities, and based on the determined network capabilities. The IMG may adjust system timing and manage power consumptions for service deployment over corresponding client devices. Information may be routed or distributed by the IMRG among the client devices when needed.

Method and system for generic IP multimedia residential gateways

A system and method for processing information transport elements, such as ethernet packets, at interfaces to a forwarder. Modules that implement processing logic are allocated per interface and per direction (i.e., inbound or outbound). At any given interface, a series of modules would be used to process inbound packets; likewise, a set of modules would be used to process outbound packets. For inbound packets, the modules allocated for inbound processing are executed when the packet is received from the interface, before sending the packet on to the forwarder. For packets that are outbound from the forwarder, the modules allocated for outbound processing are applied when the packet is sent by the forwarder, prior to any other processing, e.g., queuing to hardware. To assign modules to different interfaces at a forwarder, a registration process is performed during the system start-up process, or dynamically at runtime. For any given interface and direction, modules can be prioritized, so that a packet is processed sequentially in a specific order, one module after the other.
