计算机网络管理技术

计算机网络管理技术

网络管理系统是网络的重要组成部分，是保证通信网正常、可靠、经济和安全地运行的重要支撑手段，很多网络特性的使用

和提供，在很大程度上取决于相应的网络管理系统的能力和质量。

同时，在通信网建设初期，主要是靠通信网本身的建设来提高网

络能力，随着通信设备使用水平的不断提高，当网络能力达到一

定的程度后，通信网能力的进一步提高，将由主要依靠网络本身

建设转向网络和网管系统同步建设上来。因此，从“八五”末期

开始，我国把网管系统的建设看成提高服务质量和网络能力、保

证网络运行质量、增加企业经济效益的重要手段，从而开展了较

大规模的网管系统建设。

然而，网络的快速增长使得人们对全面互联互通的要求越发迫切，但是，网络的开放是一把双刃剑，随着私人网向公众网的

迁移，任何组织都可能将其业务扩展到全球，但是与此同时，这

也使得企业面临更多种类的安全威胁。所以同时我也介绍了网络

管理中安全资源部分。

需要指出的是，日新月异的网络技术远非一篇文章所能包容的，由于我的水平和精力有限，对于欠妥乃至错误之处，希望老

师多多批评指正。

Network management system is the important composition

part of network, is to guarantee to communicate normal and reliable, is economic and run safely important support the use of means and many network properties and offer, the quality and ability that depend on

corresponding network management system greatly. At the same time, communication net is built, initial stage is to rely on the construction of communication net to raise network ability mainly, as communication equipment is used the unceasing raising of level when network ability communicate after reaching certain level to net the further raising of ability, will from major support network construction change direction network come with net pipe system on synchronous

construction. Therefore from " 85 ", final phase begins, our country serve the construction of net pipe system as raising quality and network ability, guarantee network riding

quality and increase the important means of enterprise

economic benefits, so, have developed the net pipe

systematic construction of greater scale.

However, the fast increase of network make people know mutual for overall interconnection requirement is the more

urgent , however, network open is a two benevolent swords,

along with private net to the move of the net of the public,

it is global that any organization go to its business

development probably , however with this at the same time,

this also makes enterprise be faced with the safe threat of

more kind. So at the same time, I have also introduced the

safe resource part in network management.

What needs point out is that the network technology that changes

with each passing day far not a article can contain ,

because of my level and energy is limited , for the place

of mistake, hope teachers criticizes to make a comment.
