14、务是很浪费的。 一般而言，具体的需求有：向管理员报告服务器上的流量状况、路由器上的流量过载或者网络出现瓶颈；能通过基于策略的网络管理主动采取行动，如重新启动停止的流程等；还 应该能向有关人员发出警报，如通过电子邮件或寻呼等；能够提供方便而且强大的方法，显示将受影响的业务过程、业务部门甚至个人。 2为应用软件和服务提供环境 SLA（服务水平协议）是反应当前服务状况的一个重要指标，并且逐渐被当作网管产品的重要特性来看待。所以，深刻理解网管产品中的这个重要指标具有重大的意义，有利于衡量服务水平与企业需要之间的匹配程度，从而使之用于报告、趋势分析和容量规划。 3可扩展性、易用性和集成性的结合 网络设备

15、多，故障类型多，是网管实践中的一个典型问题。因此，能够集成 第 3 方产品提供的功能是很重要的，因为大部分厂商都依赖于第 3 方厂商提供一些补充，来使它们的系统变得更为完整。因此，可扩展性成为用户选择网络管理解决方案的一个重要标准。另外，从管理的方便性考虑，一些实用的网络管理手段也必须考虑到，才能提高网络管理的效率。 值得一提的是，目前很多网管产品都提供试用版本，我们可以向一些企业提出试用申请，只有亲身体会到可扩展、易用、高集成的特点后，才能有的放矢的进行产品定型。 4标准支持和协议的独立性 SNMP 等标准已经成熟，所有人都可用它们制作产品。真正的全面网络 管理解决方案应支持现有甚至新兴的标准，将其纳入自己的体系结构。不仅要支持 SNMP，还要支持 DHCP（动态主机配置协议）和 DNS、 DMI（桌面管理规范）及 CIM（公共信息管理）。这样，无论网络管理员以后选择哪种技术或设备，解决方案都能监视和管理整个网络。因此，真正的企业网络管理解决方案应支持所有网络协议，应能在各种类型的硬件和操作系统上运行，而不仅仅贴近某个厂商或某种操作系统。
