A mapping between virtual addresses of the corresponding endpoints in the virtual topology and local addresses of the corresponding endpoints is provided.

Abstract: In one implementation, software components include an identity of a revocation authority. Prior to loading of the software in a given platform, the revocation authority is checked for any revocation messages. The revocation authority creates software component specific messages for any software components to be revoked, rather than using certificate revocation or individual licenses. The messages include mitigation information, such as instructions for automatically configuring already installed software without requiring an update or change in code.

Abstract: The present disclosure describes techniques evaluating compute and/or thermal loads (among other things) to aid in managing a collection of one or more containerized or modular data centers. For example, forecasts (or real-time measurements) of environmental factors (as well as projected computing demands) may be used to tailor the compute loads, cooling strategies or other metric of data center operations for a network of containerized or modular data centers. Doing so allows an operator of such a data center network to manage specific operational goals in real time.

The signal converter may also include: a first module operable to transform, via a Fourier Transform, the input data having N symbols from the time domain to a frequency domain; a second module operable to up-sample the N frequency domain samples so that there are 1.6N, 2N, or 2.67N frequency domain samples, for example; and then a third module operable to transform, via an inverse Fourier Transform, the 1.6N, 2N, or 2.67N frequency domain samples to an equivalent number of time domain samples at 1.6, 2.0, or 2.67 samples per symbol, respectively.

Abstract: Redundancy of data and/or inline power in a wired data telecommunications network from a pair of network devices via a selection device is provided by communicating redundant signals with each of the pair of network devices and coupling ports of the first network device and corresponding ports of the second network device to paired inputs of the selection device. The selection device operates: 1) under the control of the pair of network devices, one acting as master and one as slave, the master selecting (for each port or for all ports) one of the two paired inputs and causing the selection device to communicate data and/or inline power via a third port of the selection device to a third network device receiving data connectivity and/or inline power from the selection device; or 2) to route two redundant signals to a third network device which then selects one for use.

Abstract: In one embodiment, an apparatus includes a port channel manager for receiving information identifying switches connected to a group of physical ports at a network device and creating subgroups each comprising the physical ports connected to one of the switches. The apparatus further includes a virtual interface agent for assigning a virtual interface connecting a virtual switch to a virtual machine, to one of the subgroups. Traffic received from the virtual machine on the virtual interface is transmitted to one of the switches on one of the physical ports in the assigned subgroup. A method for grouping ports for association with virtual interfaces is also disclosed.

Abstract: A wireless node location mechanism that defines a search region to optimize the computations associated with estimating the location of a given wireless node. According to one implementation, a coverage map associated with each radio receiver that records signal strength data is defined out to a threshold signal strength level. Before computing the estimated location of a given wireless nodes, a search region is defined based on the intersection of the coverage maps associated with each radio receiver that detects the wireless node. Some implementations use information provided by the fact that certain radio receivers did not detect the wireless node to further optimize the location estimate. By defining a search region, which is a generally small area relative to the space encompassed by an entire RF environment, the present invention provides several advantages, such as reducing the processing time and/or power to compute estimated locations for wireless nodes.

Abstract: In one implementation, a campaign manager sends content including advertising related to an advertising campaign to two or more media formats or media types. A consumer engagement score is derived from the user engagement scores associated with the media formats or media types. The consumer engagement score is compared with a target engagement score to determine whether and how to continue the advertising campaign with the particular consumer or set of consumers. Tracking of the advertising campaign extends across media types such as digital television, mobile devices, and personal computers, and extends across formats such as live content, recorded content, interactive content, text messaging, and others.

Abstract: In one implementation, a conference bridge or a multipoint conference unit (MCU) receives media streams from the endpoints in the conference. The media stream may contain at least one of audio, video, file sharing, or collaboration data. The MCU measures a characteristic in each of a plurality of media streams and calculates statistics based on the individual participation levels of the endpoints. A dynamic participation indicator displayed at the endpoints shows the relative participation levels of the endpoints. For example, the dynamic participation indicator may show the names of the users in a font that changes size and/or location as the participation level changes. In another example, the dynamic participation indicator may show respective videos of the endpoints in a format and/or size that changes as the participation level changes.

Abstract: In one implementation, the information available in social networking services is leveraged by a customer service agent. Recent social media posts by customers may be accessed by a call center server either at the time of a customer service request or ahead of time. If the customer has provided any information in the social media posts related to why the customer is calling in, the customer service agent can save valuable time that is usually spent finding the source of the problem. The call center server includes a communication interface operable to receive a customer service request including a customer identity and a controller configured to query at sources of social media postings based on the customer identity. The call center server may transmit the social media postings to a device for displaying the social media postings to the customer service agent.

Abstract: In one embodiment, Dynamic Web Resource Provisioning (DWRP) is a web services based mechanism for dynamic web services application programming interface (API) extensibility. A director network device provisions one or more agent network devices with a message in the form of a POST request to a first API. The message includes instruction configured to extend a second API in the agent network device. The director network device delivers dynamic language code to the second API by way of a PUT request.

Abstract: In one embodiment, which may be implemented in either IP networks or MPLS networks, a tree of the network may be constructed at a source network device by sending only a single packet. The remaining network devices in the network replicate the packet so that a copy will reach each of the egress nodes. Along the way, identity information from each node or hop will be added to the replicated packets. As the egress nodes receive the packets, the egress nodes will each send a reply packet to the source network device. The reply packet includes a list of every hop on the path. The source network device is configured to construct a tree of the network based on the reply packets.

Abstract: A system, method and application for facilitating network support for an install-base network is provided. The method includes performing, at an access node of the install-base network, network discovery to discover one or more nodes of the install-base network. The method also includes collecting, at the nodes, their respective inventories (“network-node inventories”). The method further includes collecting the network-node inventories at the access node, and sending the network-node inventories from the access node to a back-office system external to the install-base network. The method may, optionally, include the access node aggregating the network-node inventories to form aggregate information, and sending the aggregate information to the back-office system in addition to or in lieu of the of network-node inventories.
