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： There is provided a method and system for replicating data at another location. The system includes a source node that contains data in a data storage area. The source node is coupled to a network of potential replication nodes. The processor determines at least two eligible nodes in the network of nodes and determines the communication cost associated with a each of the eligible nodes.

The selection is based on the determined communication costs and probability of concurrent failure.

摘要： Methods, apparatuses and program storage devices for constructing a network overlay via embedding an interconnection network in a network overlay graph are provided herein. The network delay distances between pairs of overlay nodes are measured on the shortest network paths. The mapping of the interconnection topology to the network overlay nodes preferably involves assigning 2m m-length binary indexes to the network overlay nodes. There is proposed herein a polynomial time algorithm for interconnection topology embedding using iterative cluster division and node binary index assignment. There is further proposed herein a method for construction of network overlays through interconnection network topology embedding, with the objective of optimizing a quality of service metric (e.g. minimization of the average network overlay routing delay).

摘要： The present invention is based on the main ideas that different sub-intervals of a resource utilization time series are to be summarized with different granularity in the time axis, depending on the values of the series over that interval. Therefore, periods of high resource utilization are represented with higher time granularity, while periods of low resource utilization are represented with lower time granularity, the value stored can represent a function of the summarized values, such as the average or maximum value of the low resource utilization period. The captured resource utilization data is used to generate profiles, wherein the profiles summarize the historical utilization data. The profiles further capture pseudo-periodic behavior over different time scales.

摘要： Resources disposed within a plurality of distributed and autonomous computing systems, each of which may have its own legacy resource discovery service, are identified and allocated. Resource identification servers disposed within each one of the distributed computing systems communicate resource attribute data to a tree hierarchy of dedicated servers. The resource attribute data are maintained in native formats within the distributed computing systems and are mapped to a common format provided by the dedicated servers. The resource attribute data are aggregated at each node within the tree hierarchy, communicated up through the tree hierarchy to one or more root nodes and replicated down through all of the nodes. Additional system robustness is provided through period resource checks and resource attribute data updates. Resource allocation queries are submitted to any level node within the hierarchy and forwarded to the proper computing system for processing.
