Abstract: A system and method for providing user-selected information to a paging-capable device. An enhanced paging system responsive to information sources and a selection device transmits information to a paging-capable device. The enhanced paging system comprises a storing means, a selecting means, a storage device, and a transmitter. Such a system can provide user-selected information to a paging-capable device, allowing the user to control what information will be sent and when the information will be sent. Intelligent-agent software can automatically search for and store information that would be of interest to the user and can alert the user that more detailed information is available. It can also send critical information to the user without user request.

Abstract: A method and system are described herein for obtaining IGP network information useful in determining network routing topologies. The method involves querying a router for its router identifier and all its area identifiers, counting the router's number of area identifiers to determine whether the router is an ABR or an ASBR, and querying the router's link state database for the lowest area identifier on the router. The method further involves importing all Type 1 and Type 2 LSAs for that area into the database of a network discovery software engine, importing from the router's link state database only those networks outside the router's autonomous system that are also directly connected to an ASBR, then moving to the next highest area identifier in the router's database to repeat importing Type 1 and Type 2 LSAs for that area into the database.

Abstract: An impact analysis software system is described which resides on a computer connected to a network in an enterprise. The system analyzes the impact of network events on the network, and includes a number of modules, including a number of data source adapters for interfacing with external data sources to thereby allow access by the system to enterprise-related data in the external data sources. The system further includes an impact analysis data structure populated with data accessed from the external data sources and defining relationships between the enterprise-related data. One or more action tree data structures comprise a routine which, when executed, acts upon the relationships defined by the impact analysis data structure to handle events. A message processor reads the network events and select one of the action tree data structures to handle each read network event.

Abstract: A monitoring system for determining accurate topology features of a network, and methods of operating the monitoring system, are disclosed. In the preferred embodiment, the system creates an accurate topology map of a given network by: obtaining a list of managed network devices; identifying trunk ports, link channel ports, and trunk channel ports; identifying link port and node ports; determining connections between the ports; storing the collected information; and displaying the network topology. Methods are disclosed for identifying link and node ports. In the preferred method, information regarding the devices; including VLAN/backplane information, router ARP table information, device interface information, and physical address information for machines and devices connected to the network is obtained. Also, the ports and/or devices are logically grouped in order to provide more accurate topology information.
