The present mechanism provides a solution to the needs described above through a system and method for managing data exchange among systems in a network. The systems and methods of the present mechanism translate data from a system specific local format to a generic interchange format object, and vice versa, with predefined stylesheets using generic components and a system specific service components which utilize a native application programming interface of the specific local system.

Method and apparatus for managing data exchange among systems in a network

A distributed computing environment in which agent processes direct their own movement through a computer network. Place processes provide a computing context within which agent processes are interpreted. An agent process controls its movement from one place process to another within the network by using a ticket. An agent process which moves from one place process to another transports definitions of classes of which objects included in the agent process are members. An agent process which moves from one place process to a second place process avoids unnecessary transportation of objects included in the agent process by substituting equivalent objects which are found in the second place process. An agent process sends clones of the agent process to several place processes simultaneously. If two clones travel along paths which are coextensive for an initial portion thereof, a single clone is transported along the initial portion of the paths and other clones are formed from the single clone, thereby avoiding transferring redundant information along communications media. Two agent processes, which occupy a single place process, interact by exchanging references to one another. The single place process ensures that neither agent process receives a reference to the other agent process without simultaneously giving to the other agent process a reference to the former agent process. Unauthorized or inadvertent excessive use of network resources by an agent process, or a place process, is prevented by associating with each process a permit which defines various capabilities and resource allowances of the process.

System and method for distributed computation based upon the movement,

A system gathers and displays information concerning status of a communications network without overloading the communications channels in the network. The monitoring system includes a monitor node, including an operator input interface. The monitor node is coupled to a first switching node in the distributed switching nodes of the network. The monitor node includes a first application maintaining topology data indicating the topology of the network and supporting a first protocol for updating the data with the first switching node. In addition, the monitor node includes a second application maintaining a list of alarm conditions entered in the node event logs in the network, and supporting a second protocol for updating the list with the plurality of distributed switching nodes. A third application runs in the monitor node for maintaining a monitor database indicating the configuration of the switching nodes as it is entered in the node configuration databases in the network. This third application also supports a third protocol for updating the monitor database with the plurality of distributed switching nodes for updates to the node configuration database. Distributed applications in the switching nodes support the protocols with the monitor node without interference with communications tasks in the network. A display application that is responsive to operator inputs identifying a subject node or other object in the network having plural windows on a display monitor, presents configuration data about the subject node, the network topology and the alarm conditions to the operator.
