    Abstract: A switching fabric, within a network switching device, may comprise a plurality of dedicated interface modules to enable the switching fabric to interface with a plurality of switching support subsystems. The switching support subsystems may comprise a memory subsystem, a content address memory (CAM) subsystem, a packet processing subsystem, and a physical layer (PHY) subsystem. The switching fabric may be operable to determine capacity and/or capability of each of the plurality of switching support subsystems; and to configure each of the plurality of dedicated interface modules based on the determined capacity and/or capability of a corresponding switching support subsystem. The switching fabric also comprises an inter-switch interface module to enable coupling the network switching device to a plurality of other network switching devices, to form a multi-device switching mesh that enable sharing of resources and/or aggregation of switching capabilities of the network switching devices.

    Abstract: Embodiments are directed to saving power consumption in packet processing devices. A method for controlling power consumption of a packet processing device includes determining a power-save link utilization based upon one or more power-save enabled links of the packet processing device, determining an aggregate minimum processing bandwidth for the packet processing device based at least upon the determined power-save link utilization, and adjusting a processing capacity of the packet processing device based upon the determined aggregate minimum processing bandwidth, wherein the power consumption is changed by the adjusting. System and computer program product embodiments are also disclosed.

    Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments for handing off wireless communication. The apparatus comprises an antenna configured to receive data from a first access point; a cache configured to store the data; and a controller configured to predict when the transceiver will hand off a connection from the first access point to a second access point and request a burst of data from the first access point to supplement the data in the cache in preparation for the hand off.

    Abstract: A gateway network device may establish secure connections to a plurality of remote network devices using tunneling protocols to distribute to the remote network devices multimedia content received from one or more content providers. The consumption of the multimedia content may originally be restricted to local network associated with the gateway network device. The secure connections may be set up using L2TP protocol, and the L2TP tunneling connections may be secured using IPSec protocol. Use of multimedia content may be restricted based on DRM policies of the content provider. DRM policies may be implemented using DTCP protocol, which may restrict use of the multimedia content based on roundtrip times and/or IP subnetting. Each content provider may use one or more VLAN identifiers during communication of the multimedia content to the gateway network device, and the gateway network device may associate an additional VLAN identifier with each secure connection.
