Abstract:
A method and software to cause a processor to implement a method to set a packet age limit in an access point of a wireless network for communicating time-sensitive data with an associated wireless client station. One method includes the client station sending feedback to the access point so that the access point can set its packet age limit. Another method includes the access point setting its packet age limit according to feedback from the associated client station and/or according to information determined at the access point about the network.
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 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 network device receives a request from a client in association with a connection, where the request indicates an amount of one or more resources that is requested to support the connection. The network device determines whether the amount of the resources is available. The network device may then allocate a level of the resources to the connection according to whether the amount of the resources is available.
Abstract:
A method and system directed to negotiating and triggering media stream synchronization at the link layer in a QoS-enabled 802.11 WLAN, or other wireless, network. In one implementation, the present invention allows for improved performance of streaming network applications, such as video conferencing, over wireless links. In one implementation, the present invention also provides an optional mechanism whereby a mobile station can signal a need for on-the-fly throttling, if an application on the mobile detects that there is a need for better synchronization of two streams, such as a lower priority stream to a higher priority stream.
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:
Techniques are provided herein for computing a video admission control metric used to determine whether to admit a new video stream to a wireless network. The video admission control metric is computed using several measurable parameters of the wireless network. The dynamic nature of this process takes into account many real-time factors that affect admission control, such as traffic load, channel conditions, and overlapping basic service set (BSS) interference.
Abstract:
A method of fabricating a chip package is provided. The chip package includes a laminate, a chip and conductive elements interposed between the chip and the laminate by which signals are transmitted among the chip and the laminate. The method includes dispensing a first underfill in a space defined between opposing faces of the chip and the laminate and dispensing a second underfill at least at a portion of an edge of the chip, the second underfill including a high aspect ratio material.
