| 摘 要： | 分析了在公共无线局域网(PWLAN)中为实现对用户统一有效管理而要求使用二层隔离技术。提出通过在AP接入点的MAC层中定义一个隔离参量dotl llsolatioll．并修改MAC层协议中Distribution_Service模块的运行状态图以实现二层隔离功能的方法。在一个基于MPC860处理器并以嵌入式Linux操作系统为软件平台的实际WLANAP接入点上实现并仿真二层隔离的功能,结果表明该方法有效可行.

| Abstract: | The need for Layer-2 isolation function to realize effective management in the Public WLAN is analyzed. Through defining an isolation parameter dot11Isolation and modifying the state machine of Distribution_Service module in MAC layer, the Layer-2 isolation function is realized in WLAN AP. A solution which realizes WLAN access point based on Motorola MPC860 processor and on embedded Linux software architecture is proposed to simulate the Layer-2 isolation function. The results show that the scheme proposed in this paper is effective and feasible. |
