  • Publication number: 20030236745
    Abstract: Methods and systems for providing differentiated service that may be employed, for example, to deliver content or services in a network environment. Differentiated services that may be so delivered include both differentiated information service that may be implemented, for example, at the system and/or processing level, as well as differentiated business service that may be implemented, for example, to differentiate information exchange between different network entities such as different network provider entities, different network user entities, etc. The methods and systems may include or facilitate provisioning of system service parameters such as service level agreement (“SLA”) policies and may be employed in network computing system environments to enable differentiated service provisioning, for example, in accordance with business objectives.

  • Publication number: 20030236961
    Abstract: Memory managements systems and methods that may be employed, for example, to provide efficient management of memory for network systems. The disclosed systems and methods may consider cost-benefit trade-off between the cache value of a particular memory unit versus the cost of caching the memory unit and may utilize a multi-layer queue management structure to manage buffer/cache memory in an integrated fashion. The disclosed systems and methods may be implemented as part of an information management system, such as a network proceessing system that is operable to process over-size data objects communicated via a network environment, and that may include a network processor operable to process network-communicated information and a memory management-system operable to manage disposition of individual memory units of over-size data objects based upon one or more parameters, such as one or more parameters reflecting the cost and value associated with maintaining the information in integrated buffer/cache memory.

  • Publication number: 20030061362
    Abstract: Methods and systems for I/O resource management that may be employed to manage information management system I/O resources based on modeled and/or monitored I/O resource information, and that may be implemented to optimize information management system I/O resources for the delivery of a variety of data object types, including continuous streaming media data files. The methods and systems may be implemented in an adaptive manner that is capable of optimizing information management system I/O performance by dynamically adjusting information management system I/O operational parameters to meet changing requirements or demands of a dynamic application or information management system I/O environment using a resource management architecture. The resource management architecture may include, for example, a resource manager, a resource model, a storage device workload monitor and/or a storage device capacity monitor.

  • Publication number: 20030046396
    Abstract: Resource usage accounting may be implemented in information management environments using resource utilization values. Resource usage accounting may be employed, for example, to make possible run-time enforcement of system operations on one or more subsystems or processing engines of an information management system, such as a content delivery system, for example, to advantageously provide intelligent admission control in a distributed environment. In one embodiment, resource usage accounting may be implemented to make possible the management of system resources on a per subsystem or processing engine basis, for example, based on at least two types of resource utilization indicative information: 1) resource usage that has been tracked internally throughout the life span of the overload and policy finite state machine module; and 2) resource status messages received directly or indirectly from one or more subsystems or processing engines.

  • Publication number: 20020120741
    Abstract: A distributed interconnect may be employed in information management environments to distribute functionality, for example, among processing engines of an information management system and/or processing modules thereof. Distributive interconnects such as switch fabrics and virtual distributed interconnect backplanes, may be employed to establish independent paths from node to node and thus may be used to facilitate parallel and independent operation of each processing engine of a multi-processing engine information management system, e.g. to provide peer-to-peer communication between the engines on an as-needed basis. These and other features of distributed interconnects may be advantageously employed to optimize information management systems operations in a variety of system configurations.
