基于策略的网络故障管理研究

随着网络规模的扩大和各种网络新应用的出现，对网络故障管理提出越来越高的要求。基于策略的网络管理是最近兴起的新潮流。策略语言是实现基于策略的管理系统的核心技术之一。Ponder是比较流行的一种策略语言，面向网络的安全策略管理，本文提出可以用于网络故障管理的EPonder语言，提出了完整的EPonder。的信息模型和部署模型。根据EPonder语言设计描述了一个基于策略的故障管理的实例的设计和实现。新的EPonder语言可以作为高质量的故障网络管理系统的设计工具。

Research on Policy -Based Fault Management

As modern computer networks increasement in size and emergence of various network new application,higher requirement of network fault management is proposed.Policy-based network fault management is a trend of rising recently.Policy language is one of the key technologies to realize policybased management system.Ponder is a popular policy language which faces to network security.This paper proposes EPonder language applying in the network fault management,EPonder information model and deploy model.An example of design and implementation of fault management is described based on EPonder.The new EPonder language can be applied as a designing tool for advanced network fault management system.
