Disclosed are network management procedures that apply measurements of traffic load to achieve greater efficiency in the operation of the network. In a method for deciding whether to route an incoming call on a selected potential service route, the potential service route is treated preferentially if each of its links has available capacity that is more than sufficient by a specified margin. In a method for computing billing revenues, the non-compliance of the network service provider with contracted requirements for carried load causes a revenue penalty to be exacted for lost bandwidth.

A method for assembling parametric information processing applications, includes: receiving a composition request; composing a processing graph for the request, wherein the processing graph represents an application that includes at least one component; identifying a deployment parameter of the component and requesting a value of the parameter; receiving the parameter value; applying the parameter value to the application; and deploying the application with the parameter value in an execution environment.

A number of Web 2.0 sites support collaborative tagging systems, which allow users to tag resources with keywords. The tags enable search and retrieval of resources both for the user and for other users, using interfaces like a conventional search form or a tag cloud. A tag hierarchy-based search and retrieval system is provided that enhances the existing interfaces by improving search recall and allowing the discovery of even poorly annotated resources. The system uses tag co-occurrence information to automatically learn tag hierarchies. The learned hierarchies are used for automatically inferring additional tags to resources. These inferences are used to improve the recall of queries issued from a search form or via a tag cloud. The learned hierarchies can be viewed as an emergent ontology that is built up through the collaborative wisdom of a large number of users.

A method for automatic composition of an information processing flow based on a user-specified processing goal, includes: selecting tags from a first plurality of tags, wherein the selected tags specify a processing goal; composing a processing graph in accordance with the processing goal; and displaying a second plurality of tags, wherein the second plurality of tags includes tags that are only relevant to the selected tags.

A method for service composition, including: receiving a tag query; composing a processing graph in accordance with the tag query, wherein the processing graph is composed by using annotated primal data and services and includes at least one of the services; and deploying the service in an execution environment.

A system and method for workload generation include a processor for identifying a workload model by determining each of a hierarchy for workload generation, time scales for workload generation, and states and transitions at each of the time scales, and defining a parameter by determining each of fields for user specific attributes, application specific attributes, network specific attributes, content specific attributes, and a probability distribution function for each of the attributes; a user level template unit corresponding to a relatively slow time scale in signal communication with the processor; an application level template corresponding to a relatively faster time scale in signal communication with the processor; a stream level template corresponding to a relatively fastest time scale in signal communication with the processor; and a communications adapter in signal communication with the processor for defining a workload generating unit responsive to the template units.
摘要:
A procedure for designing WDM optical networks provides both working circuits and protection circuits for carrying traffic demands between node pairs. The protection circuits are activated for the purpose of network recovery in case of a fault on a working circuit. Each protection circuit is link-disjoint, and preferably node-disjoint, from its corresponding working circuit. The network is subdivided into logically defined rings, such that each working and protection circuit lies on one or more of the rings. In particular embodiments of the invention, the joint routing of circuits is carried out so as to minimize the total length of the working and protection circuits according to a length that includes a weight for each link. The weight is selected to promote the efficient packing of optical fibers with wavelength channels.
