A method is presented for determining bandwidth allocations in a content distribution network that comprises multiple trees, where the root of each tree has a server that broadcasts multiple programs throughout the tree. Each network link has limited capacity and may be used by one or more of these trees. The allocation problem is formulated as an equitable resource allocation problem with a lexicographic maximin objective function that attempts to provide equitable service performance for all requested programs at the various nodes. The constraints include link capacity constraints and tree-like ordering constraints imposed on each of the programs. The algorithm provides an equitable solution in polynomial time for wide classes of performance functions. At each iteration, the algorithm solves single-link maximin optimization problems while relaxing the ordering constraints, selects a bottleneck link and fixes various variables at their optimal value.

A system capable of dynamically reserving bandwidth and adjusting bandwidth reservations for active sessions of data communication in a data communications device is provided. The system generally separates the operation of bandwidth allocation and adjustment from the operation of data transport through the device, thereby allowing bandwidth reservations and adjustments to be made without disturbing sessions of data communication that are actively being transported through the device. The system can accept requests to allocate or reserve bandwidth in a data communications device using bandwidth reservation protocols such as RSVP. The reservation requests create sender state data that can be used to compute resource allocation data. The resource allocation data can be used to label data storage locations in a data storage mechanism according to the required bandwidth reservations. A data scheduling apparatus, which is ignorant of particular sessions and specific amounts of reserved bandwidth, examines data and deposits data into data storage locations having a label corresponding to a session identification specified in the data, if any. If an unknown or no session identification is specified in the data, the data scheduler deposits data into a data storage location that is unlabeled or that has an unreserved label. Thus session bandwidth is determined by the percentage of labeled data storage locations for the session. Changes in bandwidth reservations are reflected in the separate operation of alterations made in the data storage labeling scheme, and do not affect the data scheduler, or data dequeuing mechanisms, thus allowing data sessions to continue without interruption during bandwidth adjustments.

A system and method for accelerating input / output (IO) access operation on a virtual machine, The method comprises providing a smart IO device that includes an unrestricted command queue (CQ) and a plurality of restricted CQs and allowing a guest domain to directly configure and control IO resources through a respective restricted CQ, the IO resources allocated to the guest domain. In preferred embodiments, the allocation of IO resources to each guest domain is performed by a privileged virtual switching element. In some embodiments, the smart IO device is a HCA and the privileged virtual switching element is a Hypervisor.

A system for assigning human resources to service tasks. A long term forecasting module enables one or more users simultaneously working on that module to assign tasks that should be fulfilled in the each specific region, based on analysis of past demand and actual service operations. A mid-term planning module enables one or more users simultaneously working on that module to roughly allocate resources to fulfill actual future tasks and expected task demands. A short-term scheduling module enables one or more users simultaneously working on that module to roughly allocate specific human resources to fulfill actual tasks. A coordination module immediately propagates any change in the parameters of the human resource assignments resulting at any one of the forecasting, planning or scheduling modules to effect the other two modules. An analyzing module repeatedly checks the assignment actual status upon any introduction of an assignment update by the forecasting and planning modules to detect discrepancies and to generate alerts to correct those discrepancies.

A method of performing packet level transmission scheduling in a communications systems including a plurality of cells, each cell including a base station and plurarity of mobile stations. The method performs scheduling while considering radio resource allocation at the wireless access node. In a schedule plan phase of the method, average power and average effective data rate are determined for all mobile stations in the system. In addition, the planned fractions of frames ρ that each mobile in the system will transmit is determined so that resources are allocated fairly. In the actual schedule phase of the method, current power and effective data rate values are compared to the average power values. This information along with the ρ values is used to determine the actual schedule of packet transmissions for all mobiles in a particular cell.
