摘要
研究了WLAN瘦AP架构下本地转发和集中转发的基本原理,分析了其基本数据流向。通过时延、丢包率、下载速率等指标的测试对本地转发和集中转发进行比较,得出两种模式的主要特性,并提出了其应用场景建议。本地转发能够减小AC压力,提高网络性能,但对组网要求较高;而集中转发对AC的加、解密要求非常高,且性能压力较大,不易组网,但安全性较高。
This paper mainly introduces the fundamental principle of the local forwarding and CAPWAP forwarding under the architecture of wire fit Access Point,and discusses the data flow direction.According to the indices test of time delay,packet loss rate,download rate,and so on,the comparison of the local forwarding and CAPWAP forwarding was made and the suggestions of application scenarios were presented.The local forwarding can reduce the pressure of AC and improve the net performance but strictly require the network technology.However,for the CAPWAP forwarding,the requirements for the encryption and decryption of AC are vary strict,and the performance pressure is greater,the composition of network is more difficult,but the network security is enhanced.
