摘要： The present invention discloses a method of improving the performance of a server enabled to permit connections to clients to persist for a duration equal to a timer value, such as Web servers utilizing HTTP/1.1. In accordance with an embodiment of the present invention, the server estimates the load on the server and uses the estimate to modify the timer value. The timer value can be chosen to balance the need to increase the throughput as seen by the clients and the server need to service the largest possible number of clients without running out of resources. The timer value can be set to a longer value when the server load is light and a shorter value when the server load is heavy. In a preferred embodiment of the present invention, the server dynamically selects the largest timer that guarantees that the server does not run out of resources under the current measured load.

摘要： A method and apparatus provide decentralized prioritized scheduling of wireless access in a carrier sense multiple access with collision avoidance (CSMA/CA) wireless local area network (LAN) is presented. Prior to and during data packet transmissions, a device station in the CSMA/CA wireless LAN continuously monitors transmission traffic in the bandwidth medium of the wireless LAN to determine whether the delay associated with pre-transmission of a data packet, due to the collision avoidance protocol in the CSMA/CA wireless LAN, exceeds the time frame in which the device station necessarily must transmit the data packet. If the delay is too great for the type of data packet to be transmitted, the device station decreases the possible range of the back-off duration of the collision avoidance protocol. Thus, the station device can increase its transmission priority by decreasing the randomly selected back-off duration range of values.
摘要翻译：一种方法和装置提供了在载波侦听下具有冲突避免的多址接入（CSMA / CA）无线局域网（LAN）的无线接入的分散优先调度。在数据分组传输之前和期间，CSMA / CA无线LAN中的设备站连续地监视无线LAN的带宽介质中的传输业务，以确定由于避免碰撞而与数据分组的预发送相关联的延迟 CSMA / CA无线局域网中的协议超过了设备站必须传输数据包的时间范围。如果对于要发送的数据分组的类型的延迟太大，则设备站减少避免冲突协议的回退持续时间的可能范围。因此，站设备可以通过减少随机选择的退避持续时间范围来增加其传输优先级。

摘要： Aspects of the invention provide a method and system for managing or coordinating data transmission in a Local Area Network (LAN) such that Quality of Service (QoS) concerns are met. A LAN resource manager (LRM) is provided for managing the LAN resources by providing solutions for providing users with several levels of QoS. Once the LRM admits a user at a certain QoS level, the level is assured within the LAN for as long as the user is in the LAN. A user may submit a request to transmit data to the LRM. The LRM may determine if time allocation is possible and allocate the time slots for data transmission. The LRM may send time slot allocation information to an Access Server in a LAN, which may inform the user of the time slot allocation and prepare a queue according to the slot allocation information.

摘要： A telephone subscriber having both a wireline and a cellular telephone can switch calls between these phones. A routing table identifies that a subscriber is entitled to this service, and a look up table maintains the telephone numbers of the two different telephones. Upon detection of a unique signal indicating a request for switching a call connected to one of the telephones to the other telephone, a connection is made to the other telephone, the two connections are bridged, and then the first connection is dropped. The routing table may be maintained in a central office and the look up table may be maintained in a mobile switching center or a fixed cellular mobility agent.

摘要： An arrangement including a scannable matrix for predicting the occurrence of a future collision of frequency hops of the channel hopping patterns on the respective activated first paths of a Bluetooth packet transmission system is described. A first coordinate of the matrix defines columns representative of a selectable window of N successive future time slots of the channel hopping patterns, and a second coordinate of the matrix defines rows each exhibiting the successive frequency hops of the patterns segments transmitted on a separate one of the activated channels during such window. The first coordinate is scanned to detect the occurrence, if any, of identical frequency hops appearing at an intersection of the then-scanned column and at least a pair of the rows. If a particular scan does not detect an occurrence of such identical frequency hops in any of the time slots of the scanned window, the first coordinate may be incremented by a selected number of time slots at the end of the scan, and the scan is then successively repeated for each new window that results. If and when identical frequency hops are detected in a particular future time slot during a scan, the channel hopping pattern(s) on a subset of the affected channels may be suitably altered to avoid the predicted collision.

摘要： Active packets are utilized by a mobile terminal in a wireless network to set-up a wireless call via a signaling process, and for mobility management via a mobility process as the mobile terminal moves from one cell to another in a subnet. Active packets instantiate an agent in the fixed network to handle signaling between the mobile terminal and the fixed network, and then instruct the agent to negotiate setup of an open channel between the mobile terminal and the destination device. Moreover, active packets foster the handoff of the mobile terminal as the terminal moves from one cell to another in a subnet. Finally, the signaling process and mobility process are coordinated so that lost active packets are mitigated during roaming by the mobile terminal.
