Quality of Service (QoS) support is provided by means of a Tiered Contention Multiple Access (TCMA) distributed medium access protocol that schedules transmission of different types of traffic based on their service quality specifications. In one embodiment, a wireless station is supplied with data from a source having a lower QoS priority QoS(A), such as file transfer data. Another wireless station is supplied with data from a source having a higher QoS priority QoS(B), such as voice and video data. Each wireless station can determine the urgency class of its pending packets according to a scheduling algorithm. For example file transfer data is assigned lower urgency class and voice and video data is assigned higher urgency class. There are several urgency classes which indicate the desired ordering. Pending packets in a given urgency class are transmitted before transmitting packets of a lower urgency class by relying on class-differentiated urgency arbitration times (UATs), which are the idle time intervals required before the random backoff counter is decreased. In another embodiment packets are reclassified in real time with a scheduling algorithm that adjusts the class assigned to packets based on observed performance parameters and according to negotiated QoS-based requirements. Further, for packets assigned the same arbitration time, additional differentiation into more urgency classes is achieved in terms of the contention resolution mechanism employed, thus yielding hybrid packet prioritization methods. An Enhanced DCF Parameter Set is contained in a control packet sent by the AP to the associated stations, which contains class differentiated parameter values necessary to support the TCMA. These parameters can be changed based on different algorithms to support call admission and flow control functions and to meet the requirements of service level agreements.

A system for generating a schedule by generating assignments for the tasks of a project and sequentially scheduling the individual assignments to available resources. First, input information is received which includes a resource calendar and a task list. A resource calendar identifies the resources available to work on a project and any constraints that are associated with the resources. A task list identifies the tasks that must be performed and any constraints that are associated with the tasks. At a minimum, the constraints associated with the tasks must identify each of the resources assigned to the task, and the work-amount that each resource must perform. Next, assignments are generated for each of the tasks. Each of the assignments identifies a specific resource and the work-amount required by the specific resource. Finally, each of the assignments are scheduled in accordance with the provided resource constraints identified in the resource calendar. The resulting schedule maximizes the utilization of the resources by scheduling on an assignment basis. The assignments are individually scheduled into the next available time-slot of the resources, thus, eliminating idle time where a resource is under-utilized.

Method of advertising on-line during, for example, a world wide web session is provided by downloading full page advertisements from a predetermined site (e.g., remote server) to a user's computer during a communication link idle time. The downloaded advertising data are stored and then displayed when the user makes a request to retrieve new data, for example, a hyperlink request to a selected remote server. The advertisement remains displayed while the connection to the selected remote server is made and at least until a portion of new content data is transmitted to the user terminal.

A method for prefetching structured data, and more particularly a mechanism for observing address references made by a processor, and learning from those references the patterns of accesses made to structured data. Structured data means aggregates of related data such as arrays, records, and data containing links and pointers. When subsequent accesses are made to data structured in the same way, the mechanism generates in advance the sequence of addresses that will be needed for the new accesses. This sequence is utilized by the memory to obtain the data somewhat earlier than the instructions would normally request it, and thereby eliminate idle time due to memory latency while awaiting the arrival of the data.

Dynamic power controller apparatus, systems and methods are provided which utilize system and user data to control power to components. The present invention employs dynamically controlled idle timeout values which are based, in part, on the historical use of the component. It can also employ user settings, event occurrences and available resources of a system to dynamically control the power to one of the system's components or a remote component. In an instance of the present invention related to hard disk power control, it is employed in an operating system's kernel where disk idleness is monitored. When the hard disk's idle time meets a dynamically computed power control idle timeout, the disk driver is commanded to power down the device.

In a mobile communication system (T1) a time interval selection means (TISM) in a network control means (RNC) determines a time interval and sends an indication about this time interval to a subscriber station (MS) in a time interval indication signal. A time interval signal determining means (TISDM) in the subscriber station (MS) detects the time interval and an IF measurement means (IFMM) carries out inter-frequency / inter-system measurements in the detected time interval specified by the network control means (RNC). In this time interval the temporary reduction of the quality of service QoS on the communication connection (CC) is planed by the network control means (RNC). However, independent as to whether a delay-sensitive or loss-sensitive data transmission is carried out, the network control means (RNC) can make provisions in order to compensate the temporary reduction of the quality of service. Such procedure is superior to performing IF measurements in an idle time interval of a compressed time slot in which a temporary degradation of the quality of service must always be accepted due to a compressed mode of operation.

A system and method for concurrent WLAN and WPAN wireless modes from a single device is presented. A client uses a Wi-Fi device's infrastructure mode to communicate in a WLAN environment and, during idle WLAN times, uses the Wi-Fi device's adhoc mode to communicate in a WPAN environment. The Wi-Fi device uses a watchdog timer to switch between infrastructure mode and adhoc mode. When the client's Wi-Fi device switches to infrastructure mode, the client's Wi-Fi device uses an infrastructure register and an infrastructure device driver to transfer data over the WLAN environment. Likewise, when the client's Wi-Fi device switches to adhoc mode, the client's Wi-Fi device uses an adhoc register and an adhoc device driver to transfer data over the WLAN environment. The client uses a code shim to act as a virtual device driver at times when either the infrastructure device driver or the adhoc device driver is inactive.

This invention relates to a dispatch control method and device for shared resource access which receives the resource request from MMNC in terms of arrival sequences, to be added into an array tail corresponding to the priority in a priority request array. The dispatcher sorts the process time by the processor to fixed dispatch periods, each is divided into multiple process time segments and a certain time slice quota is allocated to each time segment dynamically. In each period, request is selected according to the quota used situation first, secondly, if the quota is used up, the process period still has some time slices left, then selection is based on the priority of request, finally, if all the three kind requests are finished, if there are idle ones, the pre-operation request is selected to process them.

Measurement systems according to embodiments of the invention allow accurate bandwidth estimation even in non-FIFO scheduling and frame-level contention environments. In an embodiment of the invention, the approximate fraction of time that a link is idle is found by probing for idle periods (“gaps”). The fraction of idle time is then multiplied by the capacity to obtain an estimate of the available bandwidth. Gap time is estimated in an embodiment of the invention fraction by gathering samples of one-way delay (OWD) over the link in question. After the OWD is normalized and plotted, the knee in the cumulative distribution function (CDF) of OWD samples is used to identify the fraction of time that the channel is idle.

A power management scheme for use in a wireless device reduces the power consumption of the network interface module of the wireless device by selectively putting the network interface module into a low-power state for an idle time. The length of the idle time is calculated such that the amount of delayed traffic data accumulated is expected to be less than or equal to a pre-selected threshold when the network interface module is put in the low-power state for the calculated idle time. The amount of delayed traffic data as a function of the idle time is modeled using average inter-arrival and service rates that are derived from traffic statistics data.

A cyclic prioritized multiple access (CPMA) method is disclosed which includes Fixed Deterministic Post-Backoff. Fixed deterministic post-backoff reduces conflicts between access points of overlapping cells. Contention-free sessions (CFSs) can be generated, one from each overlapping cell. Each active access point engages in a fixed deterministic post-backoff. A fixed deterministic backoff delay (Bkoff times a fixed number of idle time slots) is used by all access points, with the value of Bkoff being greater than the number of overlapping cells. The Bkoff should be large enough to enable the traffic that needs to be accommodated by the channel. Each access point has a backoff timer that is counted down using the shortest interframe space possible, typically the Priority Interframe Space (PIFS). A contention-free session (CFS) is initiated when the backoff timer expires, and it is then reset to the value of Bkoff to start a new cycle. A cycle is measured in terms of idle time slots instead of a fixed time interval. Contention-based transmissions can be attempted by an access point or other stations in the cell using their assigned priority while the access point is counting down its backoff timer. A new access point can get started and resolve possible collisions by a small random backoff. Subsequent contention-free sessions (CFSs) will not conflict, given an existing sequence of non-conflicting CFSs, since the follower access point's backoff delay exceeds that of the leader's by at least one times the fixed number of idle time slots. In this manner, contention-free sessions can be conducted without interference in the first and second cells.

A two way remote communication system for a vehicle includes a fob portion and a vehicle portion. The fob portion includes a fob battery, a fob transceiver, at least one button and at least one display. The vehicle portion includes a vehicle battery, a vehicle transceiver, and at least one electrical component. The timers are synchronized to simultaneously activate and deactivate the transceivers to establish periodic time intervals when the fob transceiver is open to transmission, which establishes idle time for the fob transceiver and reduces the amount of power consumed by the fob battery.

A method and apparatus for managing IM conversations is provided. In response to idle time and, preferably, read message status, particular current conversations are removed from a list of current conversations. The removed conversations may be moved to an archive which may be automatically maintained in response to size constraints. An archive interface is facilitated to review conversations, save all or portions thereof, delete, etc. The archived conversations are preferably associated with the contact for the conversation to show a history of conversations.

Fault tolerance in a redundant array of disk drives is degraded when error conditions exist in the array. Several methods for rebuilding data of the array to remove the degradation are described. Data rebuilding for entire disk drives and partial data rebuilds of disk drives are described. All rebuild methods tend to reduce the negative affect of using array resources for the data rebuild. In one method rebuilding occurs during idle time of the array. In a second method rebuilding is interleaved between current data area accessing operations of the array at a rate which is inversely proportional to activity level of the array. In a third method, the data are rebuilt when a data area being accessed is a data area needing rebuilding.
