基于802.11r漫游性能优化的WLAN建设

摘要

采用高级安全策略的无线网络在漫游时要忍受较大的时延,在不牺牲安全性的前提下快速灵活地漫游于无线局域之间成了无线局域网搭建的重中之重。基于IEEE 802.11r协议的快速BSS切换协议,以及对密钥结构和认证过程的较大改动,采用三层漫游技术实现了能够无缝漫游的校园无线网络,经过近1年的运营证明,该文提出的方案切实有效。%The roaming of wireless net applying the high level safety strategy will have to endure a delay of a certain amount,what is of great demand is rapid and flexible roaming between wireless nets without the sacrifice of safety.This article puts forth a solution to the delay problem of the campus net in combination with IEEE 802.11r agreement.After nearly one year of operation proof the solutions put forward in this paper are practical and effective.
