A formal description of open distributed processing (ODP) trading based on guidelines for the definition of managed objects (GDMO)

New requirements of growing computer networks and information systems have an influence on extended client/server models with increased functionality. This forms the basis for service management in distributed systems which is realized by a service trading concept. This paper studies the requirements derived from the Open Distributed Processing (ODP) Reference Model in order to consider an open service market. Furthermore, it examines management possibilities for describing the service trading scenario. Because of similar architectures and properties ODP services, service offers, types, exporters and traders are mapped onto management components and modeled as managed objects. Therefore, the Guidelines for the Definition of Managed Objects (GDMO) are used. The final concept allows a precise and unambiguous study of the service trading scenario and provides means for exporting and importing of service offers in a distributed environment.

CORBA技术与开放分布式网络管理

开放分布式网络系统的出现,因其异构性和复杂性的增加,给网络的管理带来了许多难题。本文在对开放分布式处理系统和CORBA进行简要介绍的基础上,对CORBA在开放分布式网络管理系统中的应用进行了探讨,并给出了基于CORBA的网络管理系统的开发方法与步骤。     

一种CORBA技术与OSI系统管理集成的解决方案

在介绍OSI系统管理技术和CORBA技术的基础上,提出了一种CORBA技术与OSI系统管理技术集成的解决方案。该方案通过采用网关及特定转换工具来实现。目前,电舆论界是采用OSI系统管理技术,采用CMIP协议。CORBA技术与OSI系统管理技术的集成对于电信网络的发展,对于传统的网管向分布式网管方向发展都有重要意义。     

TMN-MIB编译器的实现研究

 在电信管理网(TMN)中,网络管理信息库(MIB)中被管对象的信息结构是由被管对象定义指南(GDMO)和一号抽象语法标记(ASN.1)描述的,本文提出了一种TMN-MIB编译器,即将由此定义的结构转换为用C++语言描述的实现方法.该方法首先定义了便于描述网络管理信息的容器类,完成了ASN.1类型和GDMO模板的C++描述,在此基础上讨论了MIB编译器生成ASN.1和GDMO模块的过程,最后介绍了编译器输出提供的应用程序接口(API).     

Comparison criteria for GDMO-based network management information models: A step towards the integration of management systems

The integration of Management Information Bases (MIBs) is one of the challenges of integrated network management. This is made more difficult by the existence of many different ways for structuring the MIB and defining managed objects. This paper addresses the issue of integrating GDMO-based MIBs created on the basis of different Management Information Models (MIMs). Three MIMs (NMF Library Release 1. 1, ITU-T M. 3100 and ETSI GOM) are analyzed with the help of a simple network configuration, and some MIM comparison criteria are proposed. The criteria can be used to assess the dificulty of integrating MIBs based on those models.     

基于CORBA技术的GDMO接口构建的研究

用CORBA技术构建TMN中的被管对象的接口，可以加快实现异构环境下电信网的分布式管理。通过研究TMN中的GDMO模板和CORBA中的IDL接口，可以建立二者之间的映射规则。利用这种映射关系，有助于实现GDMO中的动作、属性、通知、参数、行为等模板到IDL接口中的操作、属性、参数和注释的自动映射。     

Enabling OSI CMISE via X/Open management APIs

This paper describes the development of an industry-standard Application Programming Interface (API) which provides access to the Open Systems Interconnection (OSI) Common Management Information Service Element (CMISE). The management API solution that has been defined by X/Open^® and the results of the API experimental prototype effort performed at Bell Communications Research (Bellcore) is presented. This paper is based on and extends from a paper that was submitted to Globecom '92 [1].     

电力通信网物理资源的管理信息模型

在电力通信网中,为了实现新技术与传统技术的统一管理,利用面向对象技术定义传统通信设备的管理信息模型十分必要。因此依据电力通信网监测系统技术规范,用GDMO方法定义了被监测设备物理资源的管理信息模型,给出了被管对象的继承关系和包含关系。
