Abstract: A shared computer network includes a plurality of servers each having a server program which creates remote objects and makes references to the remote objects accessible and a client having a client program which obtains the references to the remote objects and invokes methods on the remote objects. The client program and the server program can provide both distributed method invocation so that all of the plurality of servers receive a distributed method invocation from the client and directed method invocation so that a specific one of the plurality of servers receives a directed method invocation from the client. The client program and the server program can also provide automatic directed method request routing so that the directed method invocation is transparently routed to a correct one of the plurality of servers.

Abstract: A monitoring unit for a remote site includes a processor and memory configured to receive definitions of measurements and alarms to be collected at the remote site and to store the definitions of the measurements and alarms, a plurality of port connectors for communicating the processor with downstream collection devices that collect the measurements and alarms at the remote site, and a communication system for reporting the collected measurements and alarms to upstream systems. The definitions for the alarms and measurements can be provided from the port connections, stored script processes, and SNMP proxy. The memory is configured to automatically store a history of the measurements and alarms collected which can be exported to the upstream systems. The processor is configured to collect derived measurements not directly collected from the downstream collection devices.

Abstract: A method and machine-readable medium for automatically analyzing network events using matrices is described. The method and machine-readable medium include choosing the focal event or object, optionally filtering events, generating and populating an object topology matrix or an event topology matrix, evaluating event vectors, analyzing the matrix according to one of several protocols, optionally displaying the results on a user interface, and optionally applying rules or policies to the analysis, if required.
