Abstract: Fast roaming across a network fabric may be provided. A route device may receive location information corresponding to a client device in response to roaming by the client device from a first access point connected to a first network device to a second access point connected to a second network device. The first network device and the second network device may comprise fabric edge nodes on the fabric network. The first network device and the second network device may be ones of a plurality of network devices in the fabric network. On detecting the roaming of the client device, the route device may be updated with the new location, and then the route device may send, to the plurality of network devices in the fabric network, the location information corresponding to the client device.

Abstract: An apparatus comprises an input node, a power rail to power a circuit load, and multiple current paths coupled in parallel with each other between the input node and the power rail. Each current path respectively provides a sense output to indicate current in the path and a current switch having a control input to control the current in the path. A control circuit, coupled to each control input individually and to each sense output individually, controls the current in each path individually based on the indicated current therein after a non-zero input voltage is initially applied to the input node, such that all of the paths concurrently conduct current from the input node to the power rail and collectively cause a total inrush current and corresponding voltage at the power rail to gradually increase.

Abstract: In one embodiment, an intermediate node in a contention-based shared-media computer network determines a scheduled window within which a packet (with an assigned priority) should be transmitted by the intermediate node. In particular, the intermediate node may specifically determine whether an actual transmission time is prior to, during, or after the window, and sets a priority of the packet as either i) a reduced priority when the actual transmission time is prior to the window, ii) the assigned priority when the actual transmission time is during the window, or iii) an augmented priority when the actual transmission time is after the window. As such, the intermediate node may then transmit the packet from the intermediate node with the set priority at the actual transmission time.

Abstract: Embodiments described herein improve availability of a power plane in a network device by using a PoE manager that is separate from an operating system in the network device. For example, when the operating system (or a PoE application executing in the operating system) becomes unavailable, either because of failure or system upgrade, the PoE manager continues managing a power plane in the network device such that connected PDs continue to receive DC power. Stated differently, by using a PoE manager that is separate from the operating system, there is no fate sharing between the PoE manager and the operating system. If the operating system is unavailable, the PoE manager continues to provide the same power allotment to the PDs. As such, updates and failures which previously made the power plane unavailable no longer affect the power supplied to the PDs.

Abstract: A forward error correction and differentially encoded signal obtained via a communication channel is supplied to a soft-input soft-output (SISO) differential decoder that is bi-directionally coupled to a SISO forward error correction decoder. Over a first portion of a plurality of decoding iterations of the differentially encoded signal, the SISO differential decoder and the SISO forward error correction decoder are operated in a turbo decoding mode in which decoded messages generated by the SISO differential decoder are supplied to the SISO forward error correction decoder and forward error correction messages are supplied to the differential decoder. Over a second portion of the plurality of decoding iterations of the differentially encoded signal, the SISO forward error correction decoder is operated in a non-turbo decoding mode without any messages passing to and from the SISO differential decoder. Decoder output is obtained from the SISO forward error correction decoder.

Abstract: An ad-marketplace system manages an exchange for advertisement opportunities from a plurality of content brokers. Each advertising opportunity can include one or more attributes that describe advertisement slots during a broadcast of a data stream. The ad-marketplace system can receive one or more bids for an advertising opportunity associated with a media stream, and can select a matching bid from an advertiser for the advertising opportunity. Each bid can specify one or more advertising requirements that are to be satisfied by the advertising opportunity. When the ad-marketplace system selects the matching bid, the ad-marketplace system establishes a contract between the media broker, and places an initial payment from the advertiser in escrow. The ad-marketplace system can provide a payment to the media broker after confirming that a set of consumers have consumed the advertisement.

Abstract: A technology for arrangement of interactive content on a large format display is disclosed. A heuristic determines content most likely to be interacted with by a user and rearranges content on the large format display to be closest to the user. For example, a window that was most recently interacted with can be arranged to be closest to a coordinate on the large format display that is closest to a user. Additionally, a display having a substantially “L-shaped” configuration allows for display of collaborative materials and video of remote participants simultaneously, which provides for a more natural interaction for a meeting participant interacting with the collaborative materials.

Abstract: A data-hosting system facilitates binding a decoupled name to a data object. During operation, the system can receive a command to generate a decoupled name that binds a new name to the data object. The system generates a hash for the data object based on the data object's content, such that the hash is not generated based on a name for the data object. The system then obtains a private key for signing the data object, and generates the decoupled name for the data object by encrypting the data object's hash and the new name using the private key. This decoupled name binds the new name to the data object. When a client request the data object based on the network name, the system can return the decoupled name associated with content of the data object. The client can use the decoupled name to validate the data object.

Abstract: In one embodiment, a first device in a network sends a Session Traversal Utilities for Network Address Translation (STUN) binding request towards an endpoint device of a media session between the first and endpoint devices.

Abstract: One embodiment provides a system that deletes cached content. During operation, the system generates, by a content producing device, a content object packet that includes a name for the content object and a deletion identifier that is used to verify a subsequent deletion command. The system receives a notification message that includes a routable prefix for a router and indicates that the router has cached the content object packet. The system stores in a data structure a mapping between the routable prefix, the name, and a previously generated deletion token which is used as a pre-image of the deletion identifier. In response to determining a condition to delete the cached content object packet, the system transmits a deletion command based on the routable prefix, wherein the deletion command includes the deletion token and the name for the cached copy of the content object packet to be deleted.
