网络应用基础ENSP环境的安装(NETBASE第三课)

eNSP(Enterprise Network Simulation Platform)是一款由华为提供的、可扩展的、图形化操作的网络仿真工具平台，主要对企业网络路由器、交换机进行软件仿真，完美呈现真实设备实景，支持大型网络模拟，让广大用户有机会在没有真实设备的情况下能够模拟演练，学习网络技术。

软件特点高度仿真

可模拟华为AR路由器、x7系列交换机的大部分特性。
可模拟PC终端、Hub、云、帧中继交换机等。
仿真设备配置功能，快速学习华为命令行。
可模拟大规模设备组网。
可通过真实网卡实现与真实网络设备的对接。
模拟接口抓包，直观展示协议交互过程。

图形化操作

支持拓扑创建、修改、删除、保存等操作。
支持设备拖拽、接口连线操作。
通过不同颜色，直观反映设备与接口的运行状态。
预置大量工程案例，可直接打开演练学习。

分布式部署

支持单机版本和多机版本，支撑组网培训场景。
多机组网场景最大可模拟200台设备组网规模。

免费对外开放

华为完全免费对外开放eNSP，直接下载安装即可使用，无需申请license。
初学者、专业人员、学生、讲师、技术人员均能使用，各取所需。
