Estimates of a communication system configuration, such as a DSL system, are based on operational data collected from a network element management system, protocol, users and/or the like. The operational data collected from the system can include performance-characterizing operational data that typically is available in an ADSL system via element-management-system protocols. Generated estimates and/or approximations can be used in evaluating system performance and directly or indirectly dictating/requiring changes or recommending improvements in operation by transmitters and/or other parts of the communication system. Data and/or other information may be collected using “internal” means or may be obtained from system elements and components via email and/or other “external” means. The likelihood of a model's accuracy can be based on various data, information and/or indicators of system performance, such as observed normal operational data, test data and/or prompted operational data that shows operating performance based on stimulation signals. One example of such prompted data uses frequency carrier masks to approximate the Hlog of a given channel, including information regarding bridged taps, attenuation, etc.

A new approach to maintaining concurrency in a network element management database. A background process constantly monitors the channels which carry network element configuration commands, and automatically parses any messages which carry information about the status of network elements. The information derived from parsing these messages is then used for a dynamic update of the database of network element attributes. This means that the database is completely current on the very latest status changes, and operators do not have to cross-check log files to see if their data is current. Instead, a simple database query retrieves fully current information.

One example of such prompted data uses frequency carrier masks to approximate the Hlog of a given channel, including information regarding bridged taps, attenuation, etc. Scanning, wherein a number of line profiles are used in connection with DSL loops having known configurations, can be used to generate a database or library of loop configuration information. One or more of the line profiles can be used with an unknown DSL loop to generate operational data from the unknown DSL loop that is compared to the loop configuration information in the database, allowing identification of loop configuration information pertaining to the unknown DSL loop. The unknown DSL loop operational data also can be used to determine whether one or more bad splices are present on the unknown DSL loop and, in some cases, the approximate or exact bad splice(s) location(s).

An element management system in which: a list of fully-qualified versions of network elements is maintained, and the interface to each network element is managed in accordance with the highest fully-qualified version which is no later than the network element's actual version date, EVEN IF there is also a fully-qualified later version. By specifying a “managed level” which is fully qualified and is guaranteed not to be later than the actual revision of the network element, the possibility of hidden incompatibility is reduced. (Network elements are expected to be backwards compatible, but the addition of features may introduce some hidden forward incompatibility.).

In a communication network, the network management system NMS keeps one or more element management system EMS in synchronization of network topology changes using requests that are automatically generated or manually requested and then sent from the NMS to the affected EMS(s) whenever a node topology change is made at the NMS. Examples of changes are node creation, node move, node group move, node group renaming, etc. As the changes are completed in the EMS topology database, the EMS sends acknowledgments of the request to the NMS. This functionality requires verification of the validity of the request for that specific EMS, before the change is implemented at the NMS.

An element management system enables a network management server to provide a variable value to a management information base of a managed device independent of whether the managed device is served by a network address translation firewall. The element management system comprises an SNMP message manager which receives periodic heart beat frames from the managed device and stored identification of a heart beat channel in association with identification of the managed device in a registration table. The heart beat channel comprises the source socket and destination socket of the heart beat frame. The SNMP message manager further uniquely associates an assigned UDP port number with the managed device and provides the unique association of the assigned UDP port and the managed device to the network management server. The SNMP message manager further receives an SNMP Set from the network management server embodied as an IP frame addressed to the assigned UDP port number, looks up the managed device associated with the assigned UDP port number, and sends the SNMP Set to the managed device using the heartbeat channel.

Systems and methods for obtaining logical layer information in a frame relay and/or asynchronous transfer mode (ATM) network are described. In an exemplary embodiment, a physical layer test system, such as an integrated testing and analysis system, communicates with a broadband network management system, which in turn communicates with an element management system for a frame relay and/or ATM network.

An element management system that can itself be used to perform automatic remote backup of the network elements. A backup procedure is launched on a programmed schedule, to maintain a centrally located copy of the local data stored in the network elements (or their subcomponents). In accordance with a particular embodiment of the present invention, a computer/software system for managing telecommunication network elements includes one or more operator-driven processes which monitor and manage network elements in real time, using at least one telecommunications network control channel. Background processes which remotely back-up information which had been locally stored in ones of said network is automatically initiated.

Typically, paths in a network are set up via direct provisioning performed by an Element Management System/Network Management System/Operations Support System, i.e. a platform supporting multiple Wavelength Division Multiplexed spans in order to provide Network Management services/a system responsible for managing at least part of the network, and communicating with agents in order to help keep track of network resources, statistics, and performance. Alternatively, paths in the network are set up via automated nodal software that is capable of performing routing under EMS/NMS/OSS command. A relatively recent protocol, Session Initiation Protocol, has evolved for use in conjunction with multimedia devices in order to locate and connect devices together. The present invention alters the fundamental assumption that SIP is used to trigger network connections between devices, and offers a new idea that SIP can be used to tie together network equipment in a plurality of settings, such as telecommunications, cable, wireless, enterprise, etc., across different transport network technologies, including optical, Time Division Multiplexed, and packet.

The invention relates to a method and a system based on a northbound interface to realize network management. The northbound interface caches alarm information and the received alarm information is grouped and done with association analysis according to the ID of an element management system. The alarm information is divided into the following types: filtered alarm information, combined alarm information, compressed alarm information and inhibited alarm information. An alarm analysis device analyzes the alarm information according to alarm time to obtain association alarm information. A fault analysis device generates the dependency relationship of communication equipment according to the association alarm information sent by the alarm analysis device. An alarm treating device correspondingly treats the alarm information according to the types of the alarm information and conducts alarm notice or early fault alarm according to the dependency relationship in a network topological diagram generated by the fault analysis device. By treating the alarm information, the invention relieves the load of the northbound interface and improves the efficiency of the network management system in treating the alarm information.

The present disclosure relates to a database (DB) synchronization apparatus of a transmission network system which includes a plurality of network elements (NEs) and an Element Management System (EMS). Each of the NEs may include a common memory in which DB information and alarm state information are rearranged and a sync-related memory of the same pattern as the common memory for maintaining DB identity with the EMS. The EMS may include a EMS sync-related memory for storing the DB and the information of the sync-related memory of the plurality of NEs, and a EMS common memory corresponding to the common memory (CM) of the NE. A common memory which reflects database information and the current alarm information to the NEs, and a sync-related memory which stores data prior to a T-second period are built on the NEs, and these two memories are compared in block units to thereafter transmit only modified block data to the EMS. Accordingly, there is the advantage that since synchronization is established by the comparison of the memories, an initialization execution time is very fast, and a real-time data monitoring and management is convenient.

A mediator for efficiently exchanging management data in a hierarchical management network for managing network elements of a data transport network partitions resources of the network elements among a plurality of management representations of the network elements and selectively forwards management data associated with respective management representations to a higher level of the hierarchy. The mediator modifies the management data so that the higher level (i.e. a northbound element management system or a network management system) receives the management data in a view consistent with the management representation of the network element. Client-based management representations may be created to permit clients to manage selected resources of a network element, and testing-based management representations may be created to facilitate concurrent testing of a network element.

A system and method for simplifying management information discovery in a Triple Play provider network involves configuring an element management system (EMS) database to store DHCP information, and configuring the EMS to serve the information to a subscriber service controller or other operations support services component.

A method and apparatus for adapting a network topology including at least one hybrid digital cross-connect system (DCS)/SONET ring structure such that DCS network elements are managed by a DCS element management system, while SONET network elements such as ring structures are managed by a SONET element management system. A digital link is created to separate pure DCS equipment from SONET equipment within the hybrid DCS. Based on this separation, the hybrid DCS is logically decomposed into separate DCS and SONET equipment such that a SONET ring structure including an add-drop multiplexer (ADM) included within the DCS may be managed as a homogeneous SONET ring by a SONET network element manager, while the DCS equipment is managed by a DCS element manager.
