Executive Summary

The increasing availability of high speed Internet access and the decreasing cost of wireless technologies have increased the number of devices in the home that wirelessly connect to the Internet. While home user applications often have different network requirements, the wireless Access Point (AP) typically gives them all the same treatment. It has been shown that applications that are sensitive to delay, such as VoIP, remote login and online games suffer degraded performance when running concurrently with applications that expand to fill the available capacity, such as file sharing and downloading. Unfortunately, there are few mechanisms available at the AP to mitigate these effects other than for users to explicitly classify traffic based on port numbers or host IP addresses.
