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.

Abstract: Disclosed are various embodiments for an interface between a host device and one or more peripheral devices in a computing system. A peripheral-side controller, a host-side controller, and a peripheral-side translator are located on a peripheral device that is in communication with a host device. The peripheral-side translator transfers data from an internal bus in the peripheral device to an external interface for the peripheral device. The internal bus is associated with a first bus protocol, and the external interface is associated with a second bus protocol.

Abstract: Communication devices may determine routes for packets based on packet marking, routing parameters and/or costs associated with routes. A route may be selected and the packets may be communicated via the selected route. The parameters may comprise service class, real time compression, packet preemption, quality measurements, tier bypass and/or power usage information. The costs may comprise capacity, efficiency and/or performance information for power usage, bandwidth, memory and/or processing. The marking may comprise traffic type, user device capabilities, service class, quality measurements, latency requirements and/or power usage information. Endpoint devices, software applications and/or service providers may insert the marking into packets.

Abstract: One or more processors and/or one or more circuits in a user device may be operable to communicate a request for desired content to content and service providers. Two-tiered responses may be received, responsive to the request, for providing the desired content to the user device and/or other devices. The request may initiate a parallel process between the content and service providers. A response related to the value of the requested content and a response related to the delivery cost of the requested content may be received from content and/or service providers by the user device. A profile of the end user device may be configured for automatically generating the capability and/or requirements in the request, and may be stored in the end user device. The end user device may include a handheld wireless device. Delivery of the content may be at a desired price and/or at a desired time. The request for content may be submitted via a website.
