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.

The invention relates to a network management method wherein: a service management equipment holds the mapping of services and virtual networks as management information; a managed server sends an advice to a VLAN management equipment when its status changes; and the VLAN management equipment receives the advice and refers to the information contained in the advice to thereby identify the managed server and the connection port of a network switch, and configures a virtual network belonging to the identified port of the network switch. The method alleviates the task of reconfiguration associated with the adding or deleting of servers.

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.

Systems and methods for network service management, wherein the internet service management system includes one or more components which collectively enable an administrator to obtain a site-wide view of network activities on servers such as web servers, FTP servers, e-mail servers, domain name servers, etc. In addition to collecting information relating to web server latency and processing time, the internet service management system may collect actual user transaction information and system information from end users on client computers. The internet service management system may provide domain summary information for a domain, or it may provide management information organized by "categories" according to how a site manager wants to view and manage his business; e.g., byline of business (books, auctions, music, etc.), by site function (searches, shopping cart, support, quotes, sales automation), or most any other categorization customers may choose.

A network switch having a shared memory architecture for storing data frames includes configuration registers that are programmable by a host processor to adaptively adjust overflow buffer locations and flow control watermark levels based on monitored network traffic. The host processor allocates shared resources by setting memory configuration registers corresponding to an external memory, where the network switch uses the external memory for storing received data frames, Management Information Base (MIB) counter values, and output port overflow data. The host processor periodically reads the MIB counter values from the external memory, and adjusts flow control watermark levels or the memory configuration registers in the network switch based on rate-based network traffic derived from the MIB counter values. PCI burst transfers between the host processor and the external memory via the network switch ensure that stored data is not lost during reconfiguration of the external memory. The disclosed arrangement enables resources used by the network switch to be adjusted to minimize congestion by borrowing resources from network ports serving idle stations.

Access control approaches are disclosed wherein managed object in Simple Network Management Protocol (SNMP) Management Information Bases (MIBs) are accessed on a per-Virtual Private Network (VPN)-basis with no modifications to existing MIBs. A manager and an SNMP Agent operating in a VPN environment agree on a mapping between SNMP securityNames and VPN IDs. Under the agreed mapping, the target VPN of any SNMP management request can be unambiguously determined from the securityName alone. For each securityName, one or more MIB Views are configured using in a View-based Access Control Model MIB (VACM MIB) table; the MIB Views specify which portions of the managed object tree can be viewed or modified by a corresponding VPN. Thereafter, a VPN-enabled device provides SNMP requests in which a VPN ID value is passed in the securityName field of the context string in the community string. The receiving device extracts the securityName, locates corresponding MIB Views using the VACM MIB table, and allows the requesting device to access only objects that are identified in the MIB Views.

An architecture for a management information system includes a backend that services information requests from a front end. The backend retrieves data from management information base(s) (MIBs) and prepares a response to the information requests. The backend maintains a cache of data recently retrieved from the MIBs and uses the cache to retrieve data, instead of making additional requests to the MIBs. The responses may be prepared from cache data only, MIB data only, or a combination of both. The back end is preferably maintained on a same segment of a network as the MIBs. Multiple MIBs may be queried from the back end, and the backend may coordinate with back ends on other segments of the network.

A networked computing system, including multiple radio access nodes (RANs), multiple radio communications controllers (RCCs), and a data communications network facilitating communications amongst the RANs and the RCCs of the system. A regional RAN receives a default eMIB associated with a first type of RAN (e.g., a macrocell, microcell, picocells, or femtocell RAN types) from a RCC, in response to a registration event of a RAN initialization process. The regional RAN maintains a dynamic eMIB comprising network operating parameters determined by various self-optimization processes. The network operating parameters of the dynamic eMIB are selected to fall within a range designated by the default eMIB. During a network failure condition, the regional RAN is configured to use a temporary eMIB comprising failure level operating parameters in order to mitigate network deficiencies caused by the network failure condition.

A method for network management includes sending a trap message from a network end switch to client premises equipment (CPE) over a network connection therebetween, informing the CPE of a change in a network management information base (MIB) of the end switch. A request from the CPE to the end switch, subsequent to the trap message, to read information from the MIB, and the information is provided from the end switch to the CPE responsive to the request. The change is determined to have been implemented by the CPE based on the request to read the information. There is thus no need for the CPE to poll the processor for further trap messages.
