Well, in the past, QoS has sometimes had more specific connotations
for particular technologies, such as ATM, but the term is now used
more broadly to refer to a network's ability to provide better service
to selected traffic for various technologies, including IP routed
IP packets could be sorted and classified into different traffic
classes (through different mechanisms) and these classes could be
handled appropriately based on various criterias including application
type, user and application ID, source or destination IP address, time
of day, ...
QoS parameters could be available bandwidth, link and end-to-end path
utilization, delay, latency, induced jitter ...
It is a very hot topic in the provider's world, since they want to
offer different types of quality - indeed for a different amount of
money. Interdomain QoS agreements and signaling are non-trivial
things to solve ;)
