A graphical policy interface architecture may enable simplified graphical development of customized policy logic for software controllers to control network services, connections, and devices. The policy logic based on graphical policy logic notation may be compiled and installed at run-time into a software controller.

Graphical policy interface for network control systems

An information processing system including at least one terminal and at least one program execution apparatus. Each terminal transmits a message containing version information indicating a program version to a program execution apparatus. Each program execution apparatus stores one or more program components, and holds in a pre-transfer information management table information on the program components. Each program execution apparatus includes a memory allocated to an activated process and temporarily storing at least one program component for execution; and also includes a post-transfer information management table holding information one or more program components. When each program execution apparatus receives from a terminal a message containing version information, a program executing unit in the program execution apparatus dynamically links one of the program components and corresponding to version information in the received message, to the memory, enabling execution of the program components in the process.

Information processing system enabling dynamically loading or replacing program component in memory allocated to activated process

Duplicates (duplicate managed objects) of managed objects that have been generated by a network element management system in order to manage the states of a plurality of network resources are produced and stored in a management information database of a network management system. Before transmitting a series of handling directives regarding a managed object generated by a network management request from a user terminal or service management system, to the network element management system, the network management system simulates the handling directives using the duplicate managed objects and notifies the source of the request of the results of simulated behavior. The network management system transmits the series of handling directives to the network element management system when the simulated behavior ends normally but does do so when the simulated behavior ends abnormally.

Network management system based upon managed objects

Image data communicating apparatus and communication data quantity adjusting method in an image data communication system suitable for use when image data is transferred in a network environment. Image data is transferred in a most suitable quantity based on traffic of a network to avoid an effect on other services provided by the network. The apparatus has a data transmitting unit for transmitting image data to another image data communicating apparatus, a traffic detecting unit for detecting traffic of the network, and a communication data quantity adjusting unit for initially setting a transmittable number of image transferring frames on the basis of the detected traffic, and for automatically adjusting the quantity of data communication in the data transmitting unit on the basis of changing traffic on the network by altering the set number of frames.
