A recent trend in interconnection network technologies
is the inclusion of various mechanisms to
support a variety of quality of service (QoS) concepts.
This has been necessitated by an increasing
number of application areas that require some
level of performance guarantees from the network
for parts of its traffic. In this article we describe
and compare the capabilities and support for the QoS of three of the most important interconnection network technology standards of today. Equalities between the technologies are explained and
differences are clarified.
