Abstract:
A packet loss reduction system. In particular implementations, a method includes responsive to indications of roaming intent of a wireless client relative to currently associated wireless access point, determining if a traffic stream associated with the wireless client is to be proactively buffered by one or more potential wireless access points; conditionally transmitting a command to the one or more potential wireless access points to cause the potential wireless access points to set up resources to proactively buffer packets of the traffic stream; duplicating received packets of the traffic stream destined for the wireless client; and transmitting the duplicate packets to the potential wireless access points for storage in a proactive stream buffer.
Abstract:
A reversible thermal thickening grease for microelectronic packages, in which the grease contains filler particles; at least one polymer; and a binder; in which the filler particles are dispersed within the binder, in which one or more segments of the at least one polymer may be attached to the filler particles prior to dispersion in the binder, and in which the polymer collapses at temperatures below a Theta temperature and swells at temperatures above a Theta temperature. During the operation of a microelectronic package, grease pump-out and air proliferation are minimized with use of the reversible thermal thickening grease, while grease fluidity is retained under repetitive thermal stresses.
Abstract:
A system and method are provided in which access point (AP) devices in a wireless local area network (WLAN) are typed or configured into one of three measurement and reporting roles: Monitor-Mode AP (MMAP), Portal AP (PAP), a Border AP (BAP) or an Interior AP (IAP). APs are assigned specific link measurement requirements according to their assigned type or role. In general, MMAPs and PAPs have the greatest measurement and reporting responsibilities, BAPs have less measurement and reporting responsibilities than PAPs and IAPs have the least measurement and reporting responsibilities. The APs generate measurements that are supplied to appropriate equipment to facilitate handover decisions with respect to a dual-mode wireless client device that roams between the WLAN and another network or vice versa. As a result, link measurements are only performed by APs in locations where such measurements are necessary for handover service, thus reducing the overall processing load on the WLAN infrastructure.
Abstract:
A voice over WLAN diagnostic system. In particular implementations, a method includes simulating, in response to a triggering event, Voice over Internet Protocol (VoIP) communications with a remote diagnostics engine; gathering metric data characterizing one or more aspects of the simulated VoIP communications; and periodically transmitting diagnostic packets including the metric data to the remote diagnostics engine; wherein the simulating VoIP communications comprises transmitting diagnostic protocol packets that simulate VoIP communications to the remote diagnostic engine; and intercepting diagnostic protocol packets received from the diagnostics engine.
Abstract:
In one embodiment, a Media Analysis and Delivery System obtains a set of media delivery rules, wherein the set of media delivery rules includes one or more triggers, each of the triggers identifying a topic of interest. The Media Analysis and Delivery System examines a media stream for at least one of the one or more triggers in accordance with the set of media delivery rules. The Media Analysis and Delivery System provides at least a portion of the media stream in response to at least one of the triggers in accordance with at least one of the set of media delivery rules.
Abstract:
A method for evaluating number of additional admissible calls for use in call admission control includes tracking a percentage of channel busy time and transmission time of downlink and uplink voice packets, receiving a call admission request, and calculating the number of admissible calls. The number of admissible calls is calculated based on a channel bandwidth requirement determined from the percentage of channel busy time and a voice packet queuing requirement determined from the transmission time of downlink and uplink voice packets. The call admission request is approved if the number of admissible calls is greater than one and rejected if the number of admissible calls is less than one.
Abstract:
In one embodiment, a method includes identifying a plurality of locations associated with a conference system that has a conference server and a mixer, and prioritizing the locations by assigning a first priority to at least a first location and assigning a second priority to a second location. The second priority is lower than the first priority. The method also includes processing received media streams such that media streams received from endpoints associated with the first location are processed as having a higher priority than media streams received from endpoints associated with the second location.
Abstract:
In one embodiment, a system and method for optimizing a neighbor AP list for a wireless station. The list is optimized based on the current location of the wireless station and the direction of motion. Neighbor APs that are not near the wireless station and/or not in the direction of motion are pruned for the neighbor AP list.
Abstract:
A method and system for network infrastructure driven context setup to facilitate roaming for a client coupled to the network. The method includes generating an optimized list of the client's neighbors. The list is suitably generated either statically or dynamically based on any number of parameters managed by the network element to ensure an optimal set of AP candidates are provided. At least one access point is selected from the optimized list. A pre-allocation of resources is initiated with the at least one access point prior to the client roaming
Abstract:
Non-corrosive thermal interface materials for use in a test structure and method of use. The test structure includes a heat sink for dissipating heat away from a device under test. The test structure further includes a non-corrosive thermal interface material disposed between the heat sink and the device under test. The non-corrosive thermal interface material is capable of withstanding test conditions for at least 60 minutes for at least 115° C. without staining or leaving residue on the device under test after baking.
