International Classification:

G06F 17/30

US Classification:

707 2, 709228

Abstract:

Methods and systems for managing the transfer of large data files across electronic data networks optimally in accordance with the desired results of the users. The present invention takes into consideration the user-defined transfer requirements, the data characteristics, and the characteristics of the entirety of the network, including both the access links and the backbone and processing and storage resources in the backbone. The present invention the enables users to more optimally transfer data within the limitations of the existing network capabilities, negating requirements to update local or remote network facilities.

International Classification:

G06F 11/30

US Classification:

713187, 726 1

Abstract:

Disclosed is an approach to system call monitoring in which authenticated system calls from an application are easily verified by an operating system kernel. The authenticated system call may be a system call augmented with extra arguments, which specify the policy for that call as well as a cryptographic message authentication code (MAC) that guarantees the integrity of the policy and the system call arguments. This extra information is used by the operating system kernel to verify the system call with little processing overhead. Versions of the applications in which regular system calls have been replaced by authenticated calls are generated automatically by a trusted installer program that reads the application binary, uses static analysis to generate policies, and then rewrites the binary with the authenticated calls. As a result, hacker attacks, malicious software and the like are less likely to be successful in compromising any computers or networks that employ such authenticated system calls.

Appl. No.:

12/321623

Inventors:

Shuyi Chen - Urbana IL, US
William Sanders - Mahomet IL, US
Matti Hiltunen - Chatham NJ, US
Richard Schlichting - New Providence NJ, US

International Classification:

G06F 11/30

US Classification:

702182, 702186

Abstract:

A method for measuring system response sensitivity, using live traffic and an analysis that converts randomly arriving stimuli and reactions to the stimuli to mean measures over chosen intervals, thereby creating periodically occurring samples that are processed. The system is perturbed in a chosen location of the system in a manner that is periodic with frequency p, and the system's response to arriving stimuli is measured at frequency p. The perturbation, illustratively, is with a square wave pattern.

Filed:

Oct 25, 2010

Appl. No.:

12/911201

International Classification:

G06F 11/00

US Classification:

714 48

Abstract:

The present disclosure relates to dynamically allocating multitier applications based upon performance and reliability of resources. A controller analyzes resources and applications hosted by the resources, and collects operational data relating to the applications and resources. The controller is configured to determine an allocation scheme for allocating or reallocating the applications upon failure of a resource and/or upon rollout or distribution of a new application. The controller generates configuration data that describes steps for implementing the allocation scheme. The resources are monitored, in some embodiments, by monitoring devices. The monitoring devices collect and report the operational information and generate alarms if resources fail.

Richard Schlichting - New Providence NJ, US

International Classification:

G06F 9/50

US Classification:

718104

Abstract:

A method and apparatus for providing a resource allocation policy in a network are disclosed. For example, the method constructs a queuing model for each application. The method defines a utility function for each application and for each transaction type of each application, and defines an overall utility in a system. The method performs an optimization to identify an optimal configuration that maximizes the overall utility for a given workload, and determines one or more adaptation policies for configuring the system in accordance with the optimal configuration.

Richard Dale Schlichting - New Providence NJ, US

International Classification:

G06F 15/173
G06F 9/46

US Classification:

709223, 719328

Abstract:

Methods, systems, and computer-readable media for providing collaborative quality of service (“QoS”) for service-oriented architectures are described. The application services in the service-oriented architecture implement a QoS application-programming interface (“API”) in addition to the traditional service API. The QoS API may include a QoS reporting interface for reporting values of QoS metrics of the application service, a QoS mechanism interface that exposes details of dependability mechanisms utilized by the application service, and/or a QoS negotiation interface that allows dynamic negotiation of what QoS properties the application service provides and how the QoS properties are provided. Service consumers may utilize the QoS API of the various application services in the service-oriented architecture to collect dependability information regarding the application services and make service provider selection decisions during discovery and dynamic binding.
