MAN向B—ISDN过渡方法的研究 总被引:1,自引:0,他引:1
本文比较了利用窄带ISDN和帧中继技术与利用城域网(MetropolitanAreaNetwork-MAN)来实现过渡的两种方案,指出利用MAN过渡到B-ISDN具有更多的优越性,MAN是为适应局域网(LAN)互连和高速数据通信而发展起来的,网距离通常可达30~50km,由于它的信元格式和传输方式上与B-ISDN的兼容性,使得它成为从现有网络向B-ISDN过渡的最佳中介域网技术。 相似文献

Telecommunication management network (TMN) systems represent diverse telecommunication domains with wide-ranging functionality which frequently employ different technologies and produce isolated solutions. Yet as telecommunications become more sophisticated, there is a growing need for telecommunication management integration and interoperability. The authors present a general TMN computing-platform architecture which is flexible and powerful enough to support contrasting TMN management applications while facilitating integration. To validate the architecture, three diverse management applications were profiled based on components of the TMN platform architecture. Core infrastructure components, required by a broad range of TMN applications, are identified and examined and TMN-specific technology is highlighted 相似文献

Java technology has largely entered the world of element, network, and service management and has undoubtedly proven useful in combination with the SNMP framework for both manager and agent side developments. However, very few experiments have been made so far trying to provide an in-depth integration of this technology within the TMN framework. In this paper we present a free software which offers a generic environment which provides a basis for reaching this integration. This environment, called JTMN, is composed of a set of Java software packages which enable both development and deployment of TMN compliant components. Not bound to any specific management platform and easily portable to any TMN system, its goal is to allow experimentation and deployment of more advanced features such as mobile agents, active network management, and advanced delegation in harmony with existing TMN approaches 相似文献

Implementing OSI agent/managers for TMN 总被引:1,自引:0,他引:1
The telecommunications management network (TMN) architecture defines a framework for the management of telecommunications networks and services. It is based on a set of TMN standards developed by the International Telecommunications Union (ITU-T), and is finding increased interest in the telecommunications industry, where rapid development of services and open architectures are in demand. Open systems interconnection (OSI) agent/managers as defined by the OSI systems management standards play a major role in the TMN architecture. However, the complexity of these standards, make the implementation of agent/managers and thus TMN systems a challenging task; methodologies and tools to ease the task of building agent/managers are needed. This article discusses the key difficulties in building OSI agent/managers and presents an architecture and a toolkit that can overcome them. The toolkit automates the generation of code that conforms to TMN and OSI standards, allowing the implementor to focus on the implementation of agent and manager specific components using the facilities provided by the toolkit 相似文献
