Formidable Tools For Capturing And Analyzing Wlan Traffic Abound

摘要

The value of capturing and analyzing network traffic is well established. After all, the generic "sniffer" has been a fixture of networking since the days of "datascopes" on RS-232 connections. Wireless links introduce a number of complicating elements to this process, however -Wi-Fi protocols are unique at Layer 2,and traffic over the air isn't serialized, as is the case with wire. Simultaneous, competing traffic is often the norm. Packet-capture tools are no longer the first-line approach to troubleshooting, and many Wi-Fi assurance suites include a variety of capabilities that can resolve even vexing problems without resorting to protocol analysis. Nevertheless, there are times when an analysis of raw, real data is the only way to go, particularly when connection and authentication challenges are being diagnosed.
