TMN-Based interoperability network administration interface

Many network events need to be handled in a timely fashion. However, current practices are not sufficient to support timely handling of network events mainly due to the lack of a real-time network management model and facilities. In this paper, we propose a network management system, named a real-time distributed network management (RTDNM), in which the telecommunication management network (TMN) model and the time-triggered message-triggered object (TMO) model are incorporated to support network management facilities and timely handling of network events. In order to realize RTDNM, temporal characteristics of managed objects in a network are modeled and CMIS/CMIP, a network management protocol used in TMN, is annotated whit real-time constraints so that timely handling of network events can be supported. A message scheduling scheme for network management is proposed to guarantee timeliness for critical network events. Finally, we present the design of our RTDNM and show current results with a prototype implementation. The scheme presented turned out to be effective for timely handling of network events.

A major concern when implementing SONET/SDH technology is the ability to effectively manage a constantly evolving network plus its elements along with new services that will be rapidly introduced. This paper describes our experience in implementing a telecommunications management network (TMN) compliant SONET/SDH network management system. The TMN concept is envisioned by the standard body as a promising approach to manage the operations, administration, maintenance and provisioning (OAM&P) functions in a multi-vendor telecommunication network. This paper presents the problems and pitfalls of TMN and outlines our TMN implementation experience in both domestic and Mexican networks.

There are many driving forces which have compelled telecommunication operators and vendors to seek new solutions in telecommunications management. Increased competition has led to an increased focus on how traditional operators can do their business better through the use of integrated service and network management systems. Moreover, there is a need to integrate legacy applications and new applications, all of which could be written in different languages, perhaps running on different platforms, and almost certainly distributed over a network. CORBA has been recognised as a key technology solution. Based on the case studies performed for the ACTS project PROSPECT, this paper discusses the advantages and disadvantages of TMN (Telecommunications Management Network) and CORBA regarding network and service management, and proposes a phased approach for TMN-CORBA co-existence in the telecommunications management arena based on the Management Systems Framework of the Network Management Forum. Moreover, it presents some initial ideas concerning required basic management functionality that serve as a background for the CORBA/TMN gateway functionality to be implemented within the PROSPECT trial network.

The electric power transmission network management is changing from decentralized to province-centralized mode to adapt to the development trend of power grid. For the current hierarchical management situation of transmission system, the paper mainly studies the centralized mode. Considering the difficulty of transform, security, the demand of bandwidth and augmentability factors, the paper proposes a hierarchical province-centralized mode based on Resource pool and states its architecture, realization methods and deployment mode of Network Manager System in Cloud, realizing the unified management, configuration and data sharing of the whole province. Deploying the network management system in the Clout is taking full use of the resource sharing, efficient management and on-demand resource of the Cloud to realize the intensification, promoting the scheduling intensive management level of Information and transmission. Introduction For a long time, the layered, graded, zoned management mode of electric power communication networks makes the network management system built and maintained by the way of multi-level scheduling mechanism. In order to fulfill the development trend of power grid, power transmission network management should be developed from the provinces and cities separated pattern to the province-centralized mode to realize unified management, unified configuration and sharing of the communication network data within province and achieve the purpose of concentrate and highly active management, reasonable resource-configuration and optimizing the structure of the network resources. Deploying the communication network management centrally is an effective way to enhance the level of intensive management, which, whereas, will cause the load that systems deal with increase sharply. However, Cloud computing technology integrates resources into form Cloud in order to get higher utilization of computing and storage, having a strong computing power and storage capacity. With the development of Cloud construction, deploying communication network management in the pool can improve data reliability and security. This paper puts forward a hierarchical province-centralized mode based on Cloud by researching on concentrated-model of Transmission Network Management, and describes the model in detail. Discussed Problems Power system communication network is the important technology support and infrastructure platform of the grid. As an important guarantee of power grid security, stability and economic running, communication network management system is the important technology means of the communication network management and maintenance. International Power, Electronics and Materials Engineering Conference (IPEMEC 2015) © 2015. The authors Published by Atlantis Press 596 Communication network management system At present, the general transmission network management system is divided into Element Management System(EMS), Subnet Management System(SNMS) and Network Management (NMS) in terms of the management level. EMS is based on the device manager and realizes the management of safety, configuration, performance and alarm for specific equipment; SNMS can divide the network elements into various subnets, not only manage the elements equipments but also the topological relation between them. NMS is a higher level than the SNMS and manage multiple SNMS systems at the same time through network. It configures the router for each business level, and also shows the network elements’ circumstances of each time slot and the business relationships at all levels in details. The relationship of different level network management system is showed as the figure 1.

The integration of telecom energy systems within today's evolving definition of network management systems (NMSs) is discussed, emphasizing the viewpoint of the various generic network management centers (NMCs) in an attempt to determine where telecom energy systems fit into NMSs and the telecommunications management network (TMN). As the levels of key competent network support system (NSS) personnel continue to dwindle, companies are being forced to install mechanized systems to meet today's required performance levels of per capita personnel effectiveness. The author categorizes the evolving staffing levels of NSS personnel, identifies the specialized needs of each user station type, and correlates that information with the design requirements of the evolving mechanized network management systems.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Power communication integrated network management system plays a significant role in the planning, design and maintenance of the whole power communication network. This paper analyzes the characteristics of the current power communication network and the corresponding integrated network management system, and improves the design of the existing power communication network integrated network management according to Sdn. This network management system can be used as a supplementary system for the current power system integrated network management function, realizes the global visualization of the power communication network, and provides a strong support for the operation and maintenance of the power communication network. The test running environment is built in the laboratory to realize the mapping of physical route and logical link. The preliminary verification test of the new network management system based on openflow technology is carried out, and the key design methods and ideas of the system are given.

This paper describes work carried out as part of the EURESCOM project P515 “European Switched VC-based ATM Network Studies for Advanced Service Features”. The paper describes specifications for the automated inter-domain exchange of accounting, charging and billing information. The specifications define management functionality and information models which support the exchange of information, both between a customer Network Management System (NMS) and a Service Provider (SP) NMS and between two SP NMSs. The specifications follow the Telecommunication Management Network (TMN) framework and were developed according to the NMF ensemble concept. The paper presents an overview of the specifications, explains how they can be used to support the management of accounting in telecommunications networks and describes our experiences in using the ensemble technique.

As telecommunications networks and services are getting larger and more complex, telecommunication service providers around the world are desperately looking for solutions to manage and control them. A telecommunications management network (TMN) has been envisioned to provide a framework for the operation, administration, maintenance and provisioning (OAM&P) of telecommunications networks and services in today's open, multi-vendor environment. Due to the inherent distributed nature of managing systems and managed systems, supporting distributed processing is an essential requirement in TMN. This paper examines the general requirements for supporting distributed processing for the purpose of open distributed management in TMN and proposes a solution which is based on the integrated use of two distributed processing technologies: the X.500 Directory Service and the ODP (Open Distributed Processing) Trader.

Highly automated and geographically diverse networks of networks depend on management and interoperability of equipment from numerous vendors and introduction of new technologies with existing platforms. Network management systems that were introduced in the 1980s were unable to communicate across the diverse networks and jeopardized interoperability. This realization drove the International Telecommunications Union to develop the open systems Telecommunications Management Network Standards for network management systems. Though widely accepted, the impact of these equipment and protocol standards is a concern to power management system architects. Power management standards are a certainty-its only a matter of when and what. The author discusses the standardisation in telecommunications, telecommunication network management, and the power management perspective. A proposal is made for Intelec to sponsor a Network Power Management Forum as a vehicle to coalesce these concerns and present them to standards development bodies.

The monitoring and management of computer and telecommunication networks becomes increasingly difficult as these networks grow in size and complexity. Moreover, several new functional requirements appear for these network management systems in the emerging field of digital multimedia networks. Therefore, the need for scalable and distributed network management systems based on open communication standards remains as relevant as ever. We investigate the use of Web services as an open communication standard for network management systems. After a concise description of Web services and their possible advantages for network management systems, we present a case study. A Web service architecture is used to build a network management system for a data broadcasting network to distribute digital movies. The presented architecture allows several additional management functionalities that are required in such digital content networks.

Several organizations are incorporating the architecture being developed by the Open Systems Interconnection/Network Management Forum into their network management products and systems. It is expected that, as this architecture develops, it will be the basis for multivendor exchange of network management data for the next five to ten years. This architecture and key concepts being developed by the Forum to allow the interoperation of several network management systems using an open interface are summarized. These apply to the full range of networks that must be managed, including computer and communication, local area, wide area international, voice (public and private), and packet data networks. The concepts covered include: Conformant Management Entity (CME), which is a management system that supports the interoperable interface defined by the Forum; managed objects, the abstract representations of the real resources to be managed; and the interoperable interface, which consists of a defined set of protocols (using the OSI seven-layer protocol stack) over which particular messages about managed objects are exchanged.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

The advanced intelligent network (AIN) infrastructure provides a customer provisioning service creation environment. However, this may create problems in billing, performance, and security management. As ATM technology enhances AIN services, the ATM network management system must co-exist to provide a high quality of service (QoS) to AIN and B-ISDN subscribers. The management of B-ISDN has been difficult due to the ATM characteristics. In this paper we present a design of the integrated network management system for AIN and B-ISDN. The management system provides the integrated operations system. We describe how the telecommunication management network (TMN) can collaborate to provide an integrated network management for the AIN and B-ISDN in the logical architecture layer. The architecture is discussed from the standpoint of the flow of diagnostic information and the role of equipment and personnel.

This paper presents Fujitsu's Common Foundation architecture. This architecture provides a unified approach that incorporates both network and element management. Although this architecture is based on the standard Telecommunication Management Network (TMN) concept, the Common Foundation takes that concept to a new level by addressing common issues inherent within the management of distributed systems. Thus, the Common Foundation addresses issues linked to security as well as to process, transaction, and association management. At the same time, the Common Foundation simplifies user tasks by providing a single interface into the entire network while maintaining the separation of functionality into multiple systems as defined by TMN.
