摘要：

针对大规模部署无线局域网（WLAN）存在的维护困难，成本高等问题，就应用于接入控制器(AC)和无线终端（WTP）间通信交互的CAPWAP协议进行了研究与实现。在Linux系统下实现了CAPWAP协议主要功能，如状态机管理、WTP集中配置等；搭建了本地转发架构下的WLAN集中管理系统的实现平台，并采用了Wireshark抓包工具，Chariot和Iperf软件进行测试。抓包结果验证了该架构的可行性，吞吐量和用户数据协议(UDP)测试结果表明网络性能高效稳定。

关键词: CAPWAP协议, 系统架构, 平台搭建, 测试结果, 网络性能

Abstract:

In view of maintenance difficulties and high cost in large-scale development of Wireless Local Access Network (WLAN), the Control and Provisioning of Wireless Access Points (CAPWAP) protocol that applied to communication between Access Controller (AC) and Wireless Terminator Point (WTP) was researched and implemented. In Linux environment, main features were realized, such as state machine management, and WTP centralized configuration. A platform of WLAN centralized management system based on local Medium Access Control (MAC) framework was built up. Wireshark capture tool, Chariot and Iperf were used to test the platform. The capture test results verify the feasibility of the framework, and the results of throughput and User Datagram Protocol (UDP) test also show that network performance is efficient and stable.

Key words: Control and Provisioning of Wireless Access Points (CAPWAP) protocol, system architecture, platform construction, testing result, network performance
