UTRAD-网络管理接口的新描述方法

信息模型建模是软件系统设计的一个重要方面,管理信息建模方法有三种：1）在每一个管理框架中定义管理信息模型,如OSI系统管理功能的通用支持对象;SNMP的Internet的MIB-Ⅱ;TMN框架中的通用网络信息模型和用于SDH和ATM等特定技术的管理信息模型;2）TMN框架中的方法论,此方法论在旧版的M3020定义,用于帮助管理信息模型的设计者设计信息模型;3）各种管理框架的信g模型的集成,夕USNMP／SMI未口OSI／GDMO、SNMP／SMI和CORBA／IDL及OSI／GDMO禾口CORBA／IDL。这些方法都存在一些问题,每一个管理框架中定义…

XML‐Based Network Management for IP Networks

XML‐based network management, which applies XML technologies to network management, has been proposed as an alternative to existing network management. The use of XML in network management offers many advantages. However, most existing network devices are already embedded with simple network management protocol (SNMP) agents and managed by SNMP managers. For integrated network management, we present the architectures of an XML‐based manager, an XML‐based agent, and an XML/SNMP gateway for legacy SNMP agents. We describe our experience of developing an XML‐based network management system (XNMS), XML‐based agent, and an XML/SNMP gateway. We also verify the effectiveness of our XML‐based agent and XML/SNMP gateway through performance tests. Our experience with developing XNMS and XML‐based agents can be used as a guideline for development of XML‐based management systems that fully take advantage of the strengths of XML technologies.

IPv4/IPv6转换网关的SNMP代理设计与实现

基于NAT-PT技术的IPv4/IPv6转换网关部署在IPv4/IPv6网络边缘,用于两网互通.对转换网关提供网络管理功能对保障两网互通有着重要意义.然而,网关所在网络业务流量的复杂性和其基于网络处理器的架构对网络管理的实现提出了挑战.本文提出了一种转换网关SNMP代理的设计方案,定义了NAT-PT MIB,实现了网络处理器环境下分布式MIB的采集并提供了对IPv4/IPv6两网内进行网络管理的支持.     

Development of SNMP‐XML translator and gateway for XML‐based integrated network management

The research objective of our work is to develop a SNMP MIB to XML translation algorithm and to implement an SNMP‐XML gateway using this algorithm. The gateway is used to transfer management information between an XML‐based manager and SNMP‐based agents. SNMP is widely used for Internet management, but SNMP is insufficient to manage continuously expanding networks because of constraints in scalability and efficiency. XML–based network management architectures are newly proposed as alternatives to SNMP‐based network management, but the XML‐based Network Management System (XML‐based NMS) cannot directly manage legacy SNMP agents. We also implemented an automatic specification translator (SNMP MIB to XML Translator) and an SNMP‐XML gateway. Copyright © 2003 John Wiley &Sons, Ltd.     

Exploiting agent mobility for large-scale network monitoring

As networks become pervasive, the importance of efficient information gathering for purposes such as monitoring, fault diagnosis, and performance evaluation increases. Distributed monitoring systems based on either management protocols such as SNMP or distributed object technologies such as CORBA can cope with scalability problems only to a limited extent. They are not well suited to systems that are both very large and highly dynamic because the monitoring logic, although possibly distributed, is statically predefined at design time. This article presents an active distributed monitoring system based on mobile agents. Agents act as area monitors not bound to any particular network node that can "sense" the network, estimate better locations, and migrate in order to pursue location optimality. Simulations demonstrate the capability of this approach to cope with large-scale systems and changing network conditions     

Integrating SNMP agents with XML-based management systems

XML-based network management systems are becoming more and more popular these days. However, it has to be taken into account that there is a broad existing management infrastructure based on non-XML protocols. Today, the most dominant technology in Internet management is based on the SNMP framework. This article presents an approach for seamless integration of management information supplied by SNMP agents into XML-based systems. This is done by an automated transformation of SMI MIB definitions into XML schema definitions, which implies a corresponding transformation of SNMP management information into XML documents. Furthermore, we present an SNMP-to-XML gateway that allows retrieval of such XML management information at runtime.     

Building telecommunications management applications with CORBA

CORBA is an architecture for distributing and modeling computing applications. CORBA based network management is certainly an attractive approach, as network management is in essence a distributed application. This article presents a model of Managed Objects as CORBA objects, and how CORBA services and facilities can be used to build management applications. Special attention is paid to the work that has been done in the context of TINA-C (i.e., the session model and the Distributed Management Facilities Architecture).
