摘要: 针对传统WLAN结构在大规模组网时存在的问题,对集中式WLAN体系结构进行分析,研究其通信协议部分。该文介绍了LWAPP, SLAPP, CTP和WiCoP 4种协议的特性,对IETF的CAPWAP协议进行分析,讨论了系统框架、工作原理、报文结构及安全特性。

关键词: 集中式WLAN体系结构, CAPWAP协议, 接入控制器, 无线接入点

Abstract: Aiming at the problems of large-scale WLAN which using traditional architecture, this paper analyses the centralized WLAN architecture, and researches on the communication protocol. It introduces four protocols: LWAPP, SLAPP, CTP, WiCoP, then discusses the architecture, implementation mechanism, packet format and security of IETF’s CAPWAP protocol.

Key words: centralized WLAN architecture, CAPWAP protocol, access controller, wireless access point
