说明：  此仿真为ubantu系统下的REAL仿真（网络链路的仿真），本工程可以了解路由调度的基本概念；用C语言实现Round Robin路由调度策略；熟悉链表的操作。
(This simulation under the REAL ubantu system simulation (simulation of the network link), the project can understand the basic concepts of routing scheduling Round Robin routing scheduling policy implemented in C familiar with the list operation.)
