Abstract: One embodiment provides a system that facilitates direct seeking of the ordered content of a manifest based on external metadata. During operation, the system determines, by a content producing device, a root manifest, wherein a manifest indicates a set of content objects and their corresponding digests, wherein a respective content object is a data object or another manifest, and is associated with a name that is a hierarchically structured variable length identifier (HSVLI) which comprises contiguous name components ordered from a most general level to a most specific level. The system generates an index associated with the root manifest, wherein the index allows the set of content objects indicated in the root manifest to be searched and accessed directly, thereby facilitating a content consumer to seek to a desired location in the content represented by the root manifest.

Abstract: Embodiments include detecting an increase in delay of a flow assigned to a first queue of a network device, where the increase is sufficient to cause the flow rate of the flow to decrease if the flow is delay-sensitive. Embodiments further include determining whether an amount of bandwidth consumed by the flow decreases sufficiently after the increase is detected, and assigning the flow to a second queue based, at least in part, on determining the amount of bandwidth consumed by the flow does not decrease sufficiently. Specific embodiments include evaluating a series of two or more bandwidth measurements of the flow according to a bandwidth reduction measure to determine whether the amount of bandwidth consumed by the flow decreases by sufficiently. More specific embodiments include the first queue being configured to receive delay-sensitive flows and the second queue being configured to receive delay-insensitive nice flows.

Abstract: A system that automatically configures the behavior of the display devices of a video conference endpoint. The controller may detect, at a microphone array having a predetermined physical relationship with respect to a camera, audio emitted from one or more loudspeakers, each loudspeaker having a predetermined physical relationship with respect to at least one of one or more display devices in a conference room. The controller may then generate data representing a spatial relationship between the one or more display devices and the camera based on the detected audio. Finally, the controller may assign video sources received by the endpoint to each of the one or more display devices based on the data representing the spatial relationship and the content of each received video source, and may also assign outputs from multiple video cameras to an outgoing video stream based on the on the data representing the spatial relationship.

Abstract: A client analyzes requests for network resources to determine an IP address associated with the request, such as a destination IP address of a network packet. The client device selectively routes the request and other traffic associated with the IP address. The client device establishes a tunnel or other direct connection with a remote server. Network traffic can be selectively routed to the destination IP address associated with a resource request, or to the remote server based on the destination IP address associated with the request. The system can route client network requests to the remote server based on a category or other information associated with the destination IP address. Network packets associated with malicious or suspicious IP addresses, for example, may be routed to the remote server for performance of security features, while packets associated with other IP addresses may be directly routed to their target destination.

In addition, the front plate is adapted to be compressed against an ear-facing portion of an audio transducer holding device and the fixing gasket adapted to be compressed against a non-ear-facing portion of the audio transducer holding device, whereby the audio transducer is adapted to be held within the audio transducer holding device by compressive force on both the fixing gasket and the front plate.

Abstract: Actual traffic logs of network traffic to and from host devices in a network are collected over time. Artificial traffic logs for each of multiple artificial network address translation (NAT) devices are generated from the actual traffic logs. The actual traffic logs and the artificial traffic logs are labeled as being indicative of non-NAT devices and NAT devices, respectively, to produce labeled traffic logs. From the labeled traffic logs for each artificial NAT device and each non-NAT device, respective, correspondingly labeled, network traffic features indicative of whether the device behaves like a NAT device or a non-NAT device are extracted. A classifier device is trained using the network traffic features extracted for each artificial NAT device and each non-NAT device to classify between an actual NAT device and an actual non-NAT device based on further actual traffic logs.

Abstract: A trusted guard module stores one or more identifiers, each identifier uniquely identifying a respective electronic component of one or more electronic components in a circuit, wherein each electronic component is previously programmed with its respective identifier. In one embodiment, the one or more electronic components are in communication with the guard module via a test data channel. A query is sent from the guard module to one of the components via the test data channel, requesting that the queried component provide its respective identifier to the guard module. The guard module then receives a response from the queried component via the test data channel. The guard module compares the response to the stored identifier for the queried component. If the response fails to correspond to the stored identifier for the queried component, the guard module asserts an alarm condition.

The first set of measurements is a subset of the second set of measurements. An apparatus and logic are also disclosed herein.

Abstract: Present disclosure relates to methods for preparing BGP update messages for transmission and processing received update messages. The methods are based on grouping path attributes common to a plurality of IP address prefixes into respective sets identified with respective set identifiers and, instead of duplicating path attributes in each BGP update message, including a respective identifier referring to a certain set of path attributes provided in an earlier BGP update message when sending subsequent update messages. Grouping of path attributes into individual sets associated with respective identifiers provides significant advantages by enabling re-use of the results of previous processing on both the sending and receiving sides associated with transmission of BGP update messages. In addition, such an approach limits the amount of information transmitted in the control plane because duplicate sets of path attributes may only be transmitted once and merely be referred to in subsequent update messages.

It guarantees the minimum expected delivery cost for multicast frames in the absence of any knowledge about the source and receivers.

Abstract: First call identification information is stored at a network-connected device. The first call identification information identifies a call between an initiating device connected to an Internet Protocol (IP)-based network and a called device connected to the IP-based network. The call identified by the first call identification information is established through a telephone carrier network. Second call identification information is stored in the network-connected device. A determination is made that the first call identification information and the second call identification information identify the call from the initiating device to the called device. The call is connected through the IP-based network so as to avoid the telephone carrier network based upon the determining that the first call identification information and the second call identification information identify the call.

Abstract: An example communication system comprises a media access control (MAC) scheduler in a cable network, and a full band transceiver. The MAC scheduler implements a two-dimensional transmission-reception (T-R) coordination scheme among a plurality of cable modems in the cable network. According to the T-R coordination scheme, the cable modems are categorized into interference groups, such that no cable modem of any one interference group transmits upstream in a frequency range simultaneously as another cable modem in the same interference group receives downstream in the frequency range, facilitating full duplex communication in the cable network across the frequency range. The full band transceiver implements an adaptive interference cancellation scheme, which suppresses at a receiver of the respective component, a signal transmitted by a transmitter of the respective component.
