智慧矿山中WLAN无感认证的设计与实现

Non-Aware WLAN Authentication Design and Implement in Smart Mine

智慧矿山的重要特征之一是深度互联,而网络连接是深度互联的最基本要求。针对当前智慧矿山中网络连接认证的问题,提出了基于无缝漫游的WLAN无感认证方案。该方案在扩大的二层网络之上修改了DHCP地址租约策略,避免接入设备在不同控制器之间漫游出现断线情况,同时通过采用外部认证服务器的方式,保证接入设备一次认证跨区接入,最后使用无线网二层隔离和交换机端口隔离的方式避免可能出现的广播风暴问题。

One of the important characteristics of smart mines is deep interconnection,and network connection is the most basic requirement for deep interconnection.Aiming at the current network connection authentication problem in smart mines,a WLAN non-sense authentication scheme based on seamless roaming is proposed.This solution modifies the DHCP address lease policy on the expanded Layer 2 network to avoid disconnection when the access device roams between different controllers.At the same time,it adopts an external authentication server to ensure that the access device is authenticated across regions once Access,and finally use wireless network layer two isolation and switch port isolation to avoid possible broadcast storm problems.
