摘要:
Systems and methods for providing direct broadcast satellite (DBS) and digital subscriber line (DSL) video services to multiple display devices are disclosed. Generally the disclosed system receives a plurality of DBS channels and DSL content. The system receives a first user-initiated video selection and generates a first television signal based on the first user-initiated video selection. The first television signal combines video from at least one DBS channel and video from DSL content for simultaneously displaying at least a portion of the video from at least one DBS channel and at least a portion of the video from the DSL content on a display device. The first television signal is then transmitted to a first display device. Additionally, the system receives a second user-initiated video selection, generates a second television signal based on the second user-initiated video selection, and transmits the second television signal to a second display device.

A digital subscriber line access network comprises a remote Ethernet device disposed in a serving area interface. The remote Ethernet device serves as an Ethernet bridge for a neighborhood service area. The remote Ethernet device communicates with a plurality of customer premises modems in the neighborhood service area using an Internet Protocol over an Ethernet standard with a digital subscriber line physical layer. An Ethernet switch disposed at a central office communicates with the remote Ethernet device via a fiber optic medium using an Internet Protocol over a second Ethernet standard. The Ethernet switch provides a packet data core network termination.

In one embodiment, a method includes sending an adjacency discovery message 1 from a local router over a direct link to a first neighbor router. An adjacency discovery message is not forwarded and includes a repair address. The repair address indicates the local router but is not advertised as reachable over the direct link. An outbound routing update message is sent to a different second neighbor router. The outbound routing update message is forwarded and includes reachability data that indicates the repair address is reachable. A payload of an inbound tunneled packet received at the local router and directed to the repair address is forwarded based on a destination indicated in the payload.

Techniques for recovering lost routes include receiving reported costs for transmitting data to a destination from neighboring nodes; and determining total costs as a sum of costs for transmitting data packets to the neighboring nodes and a corresponding reported cost. A selected neighboring node with a minimum total cost is determined as the next hop for the route to the destination. A feasible successor set of neighboring nodes which have reported costs less than the total cost of the selected neighboring node and excluding the selected neighboring node, and successor data about the feasible successor set, are determined. The successor data is sent to the neighboring nodes. A neighboring node that loses a route to the particular destination node is able to determine whether to query the sending node while recovering a lost route to the destination based on the successor data, thereby reducing network resource consumption.

Techniques for sharing routing information over a network include determining whether the scale of a flooding domain exceeds a threshold. If so, then a router announcement message is sent over a particular link. The message indicates the local router is a flooding domain border router (FDBR). Summary routing information is determined with less than a certain level of detail used in the flooding domain for routers connected to the local router through links different from the particular link. The summary routing information is sent over the particular link in a link state message that includes type data that indicates summary routing information that crosses a FDBR. These techniques allow automatic favorable scaling of domains of shared routing information as the size of a mobile ad hoc network grows.

摘要:
A router identifies transit links and non-transit links. Only the non-transit links are advertised as routes to adjacent routers, thereby protecting the transit links from edge traffic which terminates on a network on one of the transit links. In another aspect of the invention, an administrative whitelist supplements the routes which identify the transit link network routes. In another aspect of the invention, a method for advertising routes identifies entries in a router table as broadcast or point-to-point. Only the router table entries for point-to-point links which are not transit or broadcast links that are not for a neighboring router are advertised, whereas the point-to-point transit links or broadcast transit links are advertised as transit links if an administrative whitelist is enabled.

An athletic performance monitoring system and method are disclosed that assist a user in monitoring an athletic endeavor. A system that incorporates teachings of the present disclosure may include, for example, a local area wireless transceiver capable of receiving a signal from a motion sensor. A performance engine may be communicatively coupled to the local area wireless transceiver. In operation, the performance engine may utilize the signal from the motion sensor to generate a performance metric like average speed or distance traveled. The system may also include an output mechanism such as an audio device capable of presenting the performance metric to a user in an audible message while also being capable of playing an audio representation of music to the user.
