Abstract: Dynamic configuration of interconnected devices for measuring performance characteristics in a network is disclosed. The present invention relates to measurement of performance characteristics and, more particularly, to measurement of performance characteristics of interconnected devices in a network. In existing systems there is no mechanism to dynamically determine the performance characteristics of the network and automate the test process between devices of the network. Disclosed system allows configuring the devices such as provider edge devices dynamically in the network. Further, it is possible to determine the capabilities of the devices under test and accordingly configure the test parameters. Further, the devices may be synchronized and the test may be carried out. The test process is thus automated and hence eliminates manual configuration that is error prone and tedious.

Abstract: Data storage reliability is maintained in a write-back distributed data storage system including multiple nodes, each node comprising a processor and an array of failure independent data storage devices. Information is stored as a set of stripes, each stripe including a collection of multiple data strips and associated parity strips, the stripes distributed across multiple corresponding primary data nodes and multiple corresponding parity nodes. A primary data node maintains the data strip holding a first copy of data, and each parity node maintains a parity strip holding a parity for the multiple data strips. A read-modify-write parity update protocol is performed for maintaining parity coherency, the primary data node driving parity coherency with its corresponding parity nodes, independently of other data nodes, in order to keep its relevant parity strips coherent.

Abstract: A Resource Management and Reservation System (RMRS) for managing and reserving storage bandwidth, is a platform independent middleware layer that provides an interface to applications, their database management systems, or some other higher level data management systems like ADRS which does data management on behalf of the applications. RMRS is highly relevant in hosted environments where one or more applications may be run on behalf of multiple customers each with a unique service level agreement with the Service Provider. Through its interface to the aforementioned applications, RMRS allows each application or an application side management system to communicate expected future storage access requirements (e.g., periodic access for backups). The interface also allows applications to request urgent storage access (e.g., recovery actions may be requested without being planned ahead of time).

Abstract: The invention provides a method for improving frequency-based caching algorithms by maintaining a stable history of evicted items. One embodiment involves a process for caching data in a cache memory including logical pages including, upon detecting that a first page is being evicted from the cache memory, performing an addition process by adding metadata of the first page to a stable history list. Upon detecting a cache miss for a second page, if the stable history list contains metadata for the second page, then removing the second page metadata from the stable history list and applying a promotion determination for the second page to determine a priority value for the second page metadata and placing the second page in the cache memory based on the priority data. Upon detecting that metadata of a third page is to be evicted from the stable history list, applying an eviction determination to evict metadata of the third page from the stable history list based on a predetermined caching rule.

Abstract: A performance manager and method for managing the performance of a computer system based on a system model that includes measured entities representing the operational characteristics of the system components and relationships among the measured entities. The performance manager includes data producers for interacting with the interface agents of the components, an engine for exchanging information with the data producers and the system model, and an interaction model for determining relevant measured entities in the system model. The system model and interaction model are maintained in a repository where data might be accessed via an access interface. Incoming performance data is analyzed by an analyzer in the background to detect trends and relationships among the entities. An operator might review the relevant entities and apply controls to selected entities to manage the overall system performance as well as to resolve problems affecting the performance of the components in the system.

Abstract: A method for video playback uses only resources universally supported by a browser (“inline playback”) operating in virtually all handheld media devices. In one case, the method first prepares a video sequence for display by a browser by (a) dividing the video sequence into a silent video stream and an audio stream; (b) extracting from the silent video stream a number of still images, the number of still images corresponding to at least one of a desired output frame rate and a desired output resolution; and (c) combining the still images into a composite image. In one embodiment, the composite image having a number of rows, with each row being formed by the still images created from a fixed duration of the silent video stream. Another method plays the still images of the composite image as a video sequence by (a) loading the composite image to be displayed through a viewport defined the size of one of the still images; (b) selecting one of the still images of the composite image; (c) setting the viewport to display the selected still image; and (d) setting a timer for a specified time period based on a frame rate, such that, upon expiration of the specified time period: (i) selecting a next one of the still images to be displayed in the viewport, unless all still images of the composite image have been selected; and (ii) return to step (c) if not all still images have been selected.
