Treatment-Based Traffic Signatures

As depicted in Figure 1, today’s wireless local area networks (WLANs) concurrently support a plethora of user applications with diverse connectivity and Quality of Service (QoS) requirements. Wireless traffic flows contending for resources can degrade performance for one or more of the wireless applications. Delay sensitive applications may face high latency in the presence of competing wireless traffic that saturates the WLAN. Streaming applications that need an available bandwidth estimate to select the best encoded media for good performance face challenges doing bandwidth estimation over wireless networks. Requiring smooth data delivery, VoIP suffers from delay jitter during WLAN congestion.
