QoS: Panacea or Snake Oil?

by

IT and Telecom professionals have long been infatuated with the concept commonly referred to as QoS (which stands for Quality of Service). Of course ensuring that Voice over IP meets high voice quality requirements is a key concern when it comes to designing networks.
