Coordinating service performance and application placement management

InactiveUS20060070060A1Reducing manual administration costReduce human errorProgram loading/initiatingMemory systemsClass of serviceHuman error
Apparatus, systems and methods for service and / or business for coordinating tasks of performance management and application placement management in a dynamic fashion. An example process is dynamic in the face of fluctuations in the request load to the distributed computer system and the periodic adjustments to the placement of applications onto servers in said distributed computer system. There are two opposite functional flows in said process: a demand estimation function and a capacity adjustment function. The coordination system involves two subsystems: a demand estimator and a capacity adjuster, along with appropriate interfaces to of the performance manager and the application placement manager. This results in application placement process reacting quicker to demand fluctuations, performance guarantees are better met by rearranging the resources to be allocated to the various classes of service, and the management system works in an unsupervised mode, thus reducing manual administration costs and human errors.

System and method for utilizing informed throttling to guarantee quality of service to I/O streams

The present system and associated method resolve the problem of providing statistical performance guarantees for applications generating streams of read / write accesses (I / Os) on a shared, potentially distributed storage system of finite resources, by initiating throttling whenever an I / O stream is receiving insufficient resources. The severity of throttling is determined in a dynamic, adaptive way at the storage subsystem level. Global, real-time knowledge about I / O streams is used to apply controls to guarantee quality of service to all I / O streams, providing dynamic control rather than reservation of bandwidth or other resources when an I / O stream is created that will always be applied to that I / O stream. The present system throttles at control points to distribute resources that are not co-located with the control point. A competition model is used with service time estimators in addition to estimated workload characteristics to determine which I / O needs to be throttled and the level of throttling required. A decision point issues throttling commands to enforcement points and selects which streams, and to what extent, need to be throttled.

Methods And Systems For Dynamic Bandwidth Management For Quality Of Service In IP Core And Access Networks

Proper allocation of network bandwidth is a crucial issue in rendering certain performance guarantees to meet the growing customer demands. Hence, allocation methodologies must explicitly be carried out for these guarantees to be given as efficiently as possible since the shared resources are limited. This invention presents methods and systems for Dynamic Bandwidth Management (DBM) and Quality of Service (QoS) in packet-based networks. DBM is an algorithm that dynamically adjusts the resource allocation in the IP Access Networks based upon measured QoS at the IP Core Network through an implementation of a Feedback Control Mechanism to manage available core transport bandwidth. Such a Feedback Control Mechanism is capable of maintaining a condition of non-congestion, a sufficient and necessary condition to meet end-to-end QoS requirements in a Next Generation Network (NGN). The emphasis is given on the system implementation of QoS policies for the fair distribution of network resources through a scalable architecture comprising key Resource and Admission Control Functional (RACF) entities, namely: a Network Management System (NMS), a QoS Manager, an Access Controller Manager (ACM), the Access Controllers, and the active probes.

Method and system for determining an energy-efficient operating point of a platform

A method and system for determining an energy-efficient operating point of the platform or system. The platform has logic to dynamically manage setting(s) of the processing cores and / or platform components in the platform to achieve maximum system energy efficiency. By using the characteristics of the workload and / or platform to determine the optimum settings of the platform, the logic of the platform facilitates performance guarantees of the platform while minimizing the energy consumption of the processor core and / or platform. The logic of the platform identifies opportunities to run the processing cores at higher performance levels which decreases the execution time of the workload and transitions the platform to a low-power system idle state after the completion of the execution of the workload. Since the execution time of the workload is reduced, the platform spends more time in the low-power system idle state and therefore the overall system energy consumption is reduced.

Method and apparatus for implementing scheduling algorithms in a network element

InactiveUS20050259574A1Overcomes drawbackAccurate schedulingError preventionFrequency-division multiplex detailsDeficit round robinAnticipatory scheduling
Device-wide performance guarantees may be implemented in a network element using a pull forwarding scheme by using separate proceses on the network element communicating via handshake signals to enable coordination between the aspects of the network element. One class of processes execute at the ingress queues, a second class of process execut at junction points, and a final class of processes execute at the egress ports. The combination of these separate processes leads to the correct scheduling of frames in a device-wide manner as if there were a centralized scheduler with complete information about all queued frames. As a result, the performance guarantees of the intended scheduling algorithm are preserved and are provided in a device-wide manner. The scheduling algorithms that are supported include round-robin, deficit round robin, negative deficit round robin, weighted round robin, and strict priority.

Conflict resolution for multi-master distributed databases

Data services are often provided with various performance guarantees. Multi-master architectures, in which multiple master servers are permitted to update a portion of the data set, may facilitate some performance requirements, but may also lead to data version conflicts in which different masters have written different versions of one or more data items. Moreover, conflicts involving different data items may have to be resolved using different conflict resolution techniques. Therefore, various data items of the data set may be associated with a conflict resolution technique selected from a conflict resolution technique set, such as manual conflict resolution; a write order policy, such as last writer wins; a conflict resolution logic; and conflict resolution based on data types. A data version conflict may be resolved by identifying and invoking the selected conflict resolution technique that is associated with the data item, and applying the conflict resolution outcome to the data item.

Automated adaptive method for identity verification with performance guarantees

This invention provides an automated adaptive method for identity verification of claimants that attempt to get access into a resource by responding to a sequence of identifiers. The sequence has a specified maximal length and the identifiers are partitioned into multiple groups where identifiers in the same group are correlated and identifiers in different groups are not correlated. The method guarantees that an impostor will be accepted with a probability that does not exceed a specified parameter and that a legitimate claimant will be rejected with a probability that does not exceed a different specified parameter. The method also computes the probabilities that a legitimate claimant, or an impostor, will terminate an interrogation session with an inconclusive result, which would necessitate further manual interrogation. The method is adaptive as the conditional probabilities of an impostor's responses change throughout a session of interrogation.
