Methods and systems for operation upon one or more data processors for prioritizing transmission among a plurality of data streams based upon a classification associated with the data packets associated with each of the plurality of data streams, respectively. Systems and methods can operate to allocate bandwidth to priority data streams first and recursively allocate remaining bandwidth to lesser priority data streams based upon the priority associated with those respective lesser priority data streams.

Prioritizing network traffic

Methods and systems for operation upon one or more data processors for assigning a reputation to a messaging entity. A method can include receiving data that identifies one or more characteristics related to a messaging entity's communication. A reputation score is determined based upon the received identification data. The determined reputation score is indicative of reputation of the messaging entity. The determined reputation score is used in deciding what action is to be taken with respect to a communication associated with the messaging entity.

Systems and methods for classification of messaging entities

Methods and systems for assigning reputation to communications entities include collecting communications data from distributed agents, aggregating the communications data, analyzing the communications data and identifying relationships between communications entities based upon the communications data.

Multi-Dimensional Reputation Scoring

A data modeling studio provides a structured environment for graphically creating and executing models which may be configured for diagnosis, prognosis, analysis, identifying relationships, etc., within a process plant. The data modeling studio includes a configuration engine for generating user interface elements to facilitate graphical construction of a model and a runtime engine for executing data models in, for example, an offline or an on-line environment. The configuration engine includes an interface routine that generates user interface elements, a plurality of templates stored in memory that serve as the building blocks of the model and a model compiler that converts the graphical model into a data format executable by the run-time engine. The run time engine executes the model to produce the desired output and may include a retrieval routine for retrieving data corresponding to the templates from memory and a modeling routine for executing the executable model.

Data modeling studio

A method executed in a process control environment automatically generates, displays, and tracks check lists according to assigned work items. The work items include information such as required equipment, required safety equipment, required tools, target function, and target equipment. The target function and/or target equipment information can be associated, together or separately, with the required equipment, required safety equipment, and required tools if the required equipment and tools are not specifically included in the work items. The check lists indicate the required equipment, tools, devices, parts, maintenance materials, manuals, and/or documents, that are necessary to perform the target function on the target equipment. A check list is displayed on a user interface device, which tracks, internally or in cooperation with a supervisor engine, whether a user of the user interface device has checked off the items on the check list.

Generating checklists in a process control environment

Systems and techniques for integrating information for the planning and performance of maintenance activities are described. In one aspect, a method includes receiving a collection of descriptions of maintenance tasks in an enterprise, accessing one or more data stores to receive asset information characterizing assets in the enterprise, process information characterizing assets involved in processes of the enterprise, and process value information characterizing values of the processes to the enterprise, integrating the asset information, the process information, and the process value information to assign costs associated with performance of each of the maintenance tasks, generating a work list including a subset of the collection of maintenance tasks based on the assigned costs, and making the work list available over one or more output devices.
