VxWorks对网络支持得相当好，稳定且高效，内存池的巧妙运用实现了“零内存拷贝”
，netJobAdd函数的使用减少了中断延迟时间，用户只需要实现网络驱动就可以运行完整的
TCP/IP协议栈。通过网络下载和调试程序比串口快很多，我们已经移植好了EasyARM2200和
SmartARM2200上的VxWorks网络驱动BSP，下面通过一个例子demo3.c来讲一下VxWorks for
LPC2210网络应用编程。
这个例子是开发板上网页演示程序在VxWorks上的移植，通过实际测试(在
SmartARM2200上)，响应速度非常快(平均为0.09秒)，ping测试(74字节包)的平均响应时间
为3ms，ARP响应时间为3ms。源码如下：

下面图示说明使用方法：
和前面《VxWorks for LPC2210应用编程实战》里介绍的使用方法类似，唯一不同点是
Target Server要设置成wdbrpc。
下面只介绍不同部分的设置。
设置Target Server，使用网络RPC通信，目标机IP地址为192.168.0.2，超时和重试次
数根据需要设置，调试时如果网络速度比较慢的话(因为加入了调试信息)，使用缺省值可能
导致连接失败，正常工作时网络速度很快，不存在此问题。注意：Core File and Symbols
里的File文件要与烧写在flash里的VxWorks一致，即带调试信息的ELF文件
(vxWorks_romResident)。连接成功会显示成功信息，托盘里出现一个象靶子一样的图标。
其他操作与《VxWorks for LPC2210应用编程实战》里介绍的使用方法相同，不再赘述
。
超级终端上显示的运行信息。
用IE访问192.168.0.2就可以浏览内置网页，响应速度相当快(0.09秒)。
基于网络RPC的调试shell比基于串口的快多了，输入“i”后，几乎是一下子蹦出任务
状态列表信息。
这是ping测试的结果，通过sniffer抓包分析，ping测试(74字节包)的平均响应时间为
3ms，ARP响应时间为3ms。看来VxWorks真的不赖。
