摘要： In one embodiment, a method and an apparatus for failure-resilient forwarding of data over a computer network include introducing a marker into the data stream, e.g., at the sending node, and allowing, in turn, forwarding nodes and/or receivers to efficiently track data stream reception. The marker functions as a checkpoint for the data transport process, and is identified and indexed at each forwarding node and receiver. Each receiver saves the marker prior to delivering data to an application, thereby designating a point in the data stream at which all preceding data is confirmed to have been delivered to the application. Thus, if a forwarding node fails, the receiver may request stream data from an alternate forwarding node by specifying to the alternate forwarding node to provide data starting from the marker.

摘要： One embodiment of the present method and apparatus for time-based communications port protection includes generating a transmission period schedule that is known only by authorized network users including a server and one or more clients of the server. The transmission period schedule dictates pre-defined times at which the server and clients may communicate, e.g., to transfer data. By communicating only at these secret, pre-defined times, the likelihood that an unauthorized party will be able to disrupt service to the clients is greatly reduced.

摘要： Systems and methods are provided to determine an allocation of network resources in a distributed on-demand information technology (IT) systems using existing control mechanisms for other operating system resources in order to achieve a desired operating point within the IT system. This desired operating point is obtained by optimizing a goal-based objective function while taking into account system constraints. The relationship between utilization of all system resources, i.e. network resources and processing resources, and attainment of performance objectives is autonomously obtained for a plurality of actions that could be required by a range of system applications. This relationship is used to allocate network resources to applications while maintaining desired performance objectives. The allocation is enforced using existing control mechanisms.

摘要： A system and method are provided for autonomic system management in a computing system containing system resources including network resources and multiple resource demands, or processes. The computing system may be a stream-processing system or other real-time computer management system, such as workload management, or a virtualization engine. The system and method enables achieving a better level of performance than would occur in the computing system using only existing mechanism. It permits, with very low computational overhead, achieving or driving the system closer to a user-defined system performance objective. To do so, a system performance equation is defined to determine a level of performance of the system as a function of the allocation of two or more system resources among a plurality of system resource demands or processes. From this system performance equation, a plurality of resource-specific change equations is derived. Each resource-specific change equation is capable of calculating changes in the level of performance of the system attributable to changes in the allocation of one of the system resources. The resource-specific change equation yielding the greatest change in the level of system performance at a given allocation of all of the system resources and the system resource associated with the identified resource-specific change equation are identified. The allocation of the identified associated system resource to at least one system resource demand to provide the largest increase in the level of performance of the system, and allocations for all system resources are adjusted in accordance with the modified allocation of the identified associated system resource.

摘要： Disclosed are a method, upstream processing node, and computer readable medium for dynamically stabilizing a stream processing system. The method includes receiving at least one computing resource allocation target. The method further includes determining that an input data flow rate of at least one upstream processing element varies. The computing resource is dynamically allocated to the upstream processing element in response to the input rate of the upstream processing element varying. Data flow is dynamically controlled between the upstream processing element and at least one downstream processing element.
