A Software Fault Management (SFM) system for managing software faults in a managed mobile telecommunications network. The SFM system includes an Intelligent Management Information Base (I-MIB) comprising a Management Information Base (MIB) and a Knowledge Base (KB) having a functional model of the managed network and a trouble report / known faults (TR / KF) case base. The SFM system also includes an intelligent multi-agent portion having a plurality of agents which process the software faults utilizing the functional model from the I-MIB, case-based information, and other management information. The I-MIB and the intelligent multi-agent portion are compliant with Telecomunications Management Network (TMN) principles and framework. Fault management is both proactive and reactive. The SFM system is made independent of technology-specific implementations by representing the underlying switch design knowledge in a modular and changeable form which is then interpreted by the intelligent multi-agent portion. A clear separation is maintained between the generic procedural inference mechanisms and agents, and the specific and explicit models of the different network elements of a mobile telecommunications network.

A system, method and computer program product for automatic response to computer system misuse using active response modules (ARMs). ARMs are tools that allow static intrusion detection system applications the ability to dynamically increase security levels by allowing real-time responses to detected instances of computer misuse. Several classes of ARMs exist which allow them to interface with several types of network elements found within a computing environment (e.g., firewalls, web servers, Kerberos severs, certificate authorities, etc.). The ARMs, once defined, are deployed in a "plug and play" manner into an existing intrusion detection system within a computing environment. A user (e.g., system administrator) may then configure the ARMs by linking them to specific computer misuses. Upon receipt of an instance of the computer misuse from the intrusion detection system, each ARM linked to the misuse collects pertinent data from the intrusion detection system and invokes a response specified by the ARM class and the collected pertinent data.

A method is described for controlling a shared resource for interconnecting two or more network domains being controlled by different Managers. Multiple Managers control the shared resource for the configuration of a segment of a connection between two different domains and the Managers cooperate in order to control dynamically the shared resource. Different network domains can be connected by a network element or by a link between different network elements belonging to the different network domains. In the first case the shared resource is a connection matrix of the network element, in the second case the shared resource includes the connection matrixes of the different network elements and the link between the network elements. A shared connection matrix includes some connection points for performing the cross-connections within the matrix: some connection points are controlled by one Manager, other connection points are controlled by another Manager and some shared connection points are controlled by both Managers. Multiple Managers control the shared resource by reading and writing information stored into a management information base, according to an explicit or implicit mode, or alternatevely by transmitting messages in the network directly between the Managers, according to a signalling protocol.

Managing the selection and scheduling of security audits run on a computing network. The computer network is surveyed by a security audit system to determine the function and relative importance of the elements in the network. Based on function and priority, a more thorough type of security audit is selected to run against each of the network elements by the security audit system. The security audit can also be automatically scheduled based on the information gathered from the survey. Once the system runs the security audit, a vulnerability assessment can be calculated for each element in the network. The vulnerability assessment can be presented in a format that facilitates interpretation and response by someone operating the system. The vulnerability assessment can also be used to configure and schedule future security audits.

An optical signaling header technique applicable to optical networks wherein packet routing information is embedded in the same channel or wavelength as the data payload so that both the header and data payload propagate through network elements with the same path and the associated delays. The header routing information has sufficiently different characteristics from the data payload so that the signaling header can be detected without being affected by the data payload, and that the signaling header can also be removed without affecting the data payload. The signal routing technique can be overlaid onto the conventional network elements in a modular manner using two types of applique modules. The first type effects header encoding and decoding at the entry and exit points of the data payload into and out of the network; the second type effects header detection at each of the network elements.

A Diameter router (20) is presented for performing load balancing and initial Diameter message routing in an IMS network, where clients in network elements (10) are provisioned with the address of the router and send an initial Diameter request message (41) for a given session to the router. The router selects a server (31) based at least partially on a type of IMS message session, application services, subscriber information, or billing information, and sends a relayed initial Diameter request message (42) to the selected server. The selected server sends an initial Diameter response (43) to the router which then forwards a relayed initial response (44) to the client. Thereafter, the client and the selected server send messages directly to each other for the remainder of the session.

A congestion management technique achieves an end-to-end data flow rate that is supported by a lossless communications network. The end-to-end rate extends from a source end node to destination end node of the network and is preferably at or slightly below a bottleneck rate of the network. The destination end node determines, on its own and without any help from network elements, a supportable rate of activity in the network and provides feedback to the source end node. By achieving such a rate, data transmitted by the source end node can flow through the network without loss of packets and without the use of substantial buffering.

A network-based system and method for providing anonymous voice communications using the telephone network and data communications links under the direction of a Call Broker and associated network elements. A user (the call initiator) present in a text chat room session establishes a data connection to Call Broker and, after qualifying for access (e.g., using credit card information) and providing a callback number, receives voice session information and participant access codes for each desired participant in a voice call. The initiator causes session information and participant codes to be passed to one or more selected chat participants in the current text chat room. When a selected participant uses the received session information, and enters the received participant code and a callback number, the Call Broker in cooperation with a Network Adjunct Processor (NAP) completes voice links to the initiator and the selected participant(s). The need for each party to have a second subscriber line is advantageously avoided by having the Call Broker arrange to have one or more voice links completed through a VoIP link, and further reduces the need for second lines for participants by forwarding a Call Broker—placed call to a busy participant line to the participant's Internet Service Provider (ISP), which then sends a message to the participant announcing one or more options for receiving the incoming call, including receiving the incoming call through a VoIP link.
