Abstract

With the improvement of people's living standard, the computer user is more and more, followed by a lot of questions, today I want to explain the network failure. Combination of computer technology and network technology to achieve the change of the production people, living and learning model of computer network technology convenience, low cost and fast network has become an important way of data transmission, storage and processing a. Computer network failure is extremely commo(转 载于:wWw.SmHaIDA.cOM 海达 范文 网:network,failure)n type of failure is also very complicated. Network failure, network failure to maintain the normal operation of the network, the fastest recovery and maintenance of theoretical methods and techniques to master a set of effective network is the key. If the network failure of the common faults classified to find, then no doubt be able to quickly and accurately locate the source of the problem and solve network problems. The article is mainly on the common network fault classification diagnosis。

Keyword: computer network; network failure; failure analysis; network maintenance

绪论

1 绪论

1.1 课题研究的背景

在当今这个计算机网络技术日新月异，飞速发展的时代里，计算机网络遍及世界各个角落，应用在各行各业，普及到千家万户，它给人们可谓带来了诸多便利，但同时也带来了很多的烦恼，在此我对常见的网络故障进行了分类和排查方法的介绍，相信对你有所帮助。根据常见的网络故障归类为：物理类故障和逻辑类故障两大类。

国内外正在研发故障智能诊断和报警系统的结构；采用人工智能技术，引入故障知识库和推理机制，使得对故障的诊断能够智能化，而且很好的支持系统的增量式开发。采用短信报警的方式，加入消息过滤，避免垃圾信息或者冗余信息的发送。期望在此基础上，实现一种可行的网络故障诊断和报警系统的智能排除网络故障。未来我们可能实现故障的自动定位与修补，通过有关技术实现对计算机的有效监控，保证及时预测、检测和修复网络故障，为网络提供安全可靠的运行环境。

但是，大多数网络故障还是人为给以处理和排除，此论文就是汇总出常见网络故障，对其具体故障给以相应的现象描述、原因分析和解决方案。

1.2 研究目的

二十一世纪的重要特点之一就是数字化，网络化和信息化，这是一个以网络为核心的时代。在当今这个计算机网络技术日新月异，飞速发展的时代里，计算机网络遍及世界各个角落，应用在各行各业，普及到千家万户，它给人们可谓带来了诸多便利。计算机技术与网络技术的结合实现人们生产、生活和学习模式的变革，计算机网络技术的便捷性、低成本性和快速性使得网络已经成为人们进行数据传输、存储和处理的一种重要方式之一，企业、政府部门等单位为了提高工作的效率分别建成了内部局域网、外部网，并将之誉国际互联网进行了连接。 但同时随之而来得一些网络故障也带来了很多的烦恼。

当网络遭遇到故障时，最困难的不是修复网络故障本身，而是迅速的查出故障所在，并确定发生的原因。网络故障极为普遍，故障种类也十分繁杂。要在网络出现故障时及时对出现故障的网络进行维护，以最快的速度恢复网络的正常运行，掌握一套行之有效的网络维护理论、方法和技术是关键。如果把网络故障的常见故障进行归类

The listed RR cause values are defined in Annex F.

Normal event

Abnormal release, unspecified

Abnormal release, channel unacceptable Abnormal release, timer expired

Abnormal release, no activity on the radio path Preemptive release

UTRAN configuration unknown

Handover impossible, timing advance out of range Channel mode unacceptable Frequency not implemented

Originator or talker leaving group call area Lower layer failure Call already cleared

Semantically incorrect message Invalid mandatory information

Message type non-existent or not implemented Message type not compatible with protocol state Conditional IE error

篇四：S1AP中CAUSE值查看

Cause

Cause IE 表示S1AP 协议的特定事件的原因。

不同原因值的解释在如下表格中有描述。一般而言， "not supported" 原因值表示没有相关的性能支持。另外， "not available" 原因值表示有相关的性能支持，但是没有充裕可用的资源来执行所请求的动作。
