An overview of QoS capabilities in infiniband, advanced switching interconnect, and ethernet

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.
