danwarne asks: "With VoIP becoming rapidly more popular, quality of service (QoS) settings in home routers are also emerging as a key piece of functionality for the average user. QoS settings, which allows important or time-sensitive network traffic to be prioritized over less important packets, used to only be offered for corporate-level routers. Now, many hardware manufacturers have started including such capabilities in their mainstream routers, some doing it simply by a firmware upgrade without any change to the power of the underlying hardware. The emerging problem is that most home routers don't do a very good job at all with QoS, especially under heavy load (from P2P apps, for example), and home routers don't seem to have what it takes to prioritize sending Voice over IP packets first, leading to glitchy VoIP calls. VoIP operators around the world are facing this problem as they try to turn VoIP into a 'consumer-friendly' plug-and-play service. Does anyone know if someone has done extensive testing on home routers and modem/routers that investigates their ability to deliver QoS? Also, what hardware elements would be required in a router to do QoS reliably?"
