and provide concepts and terminology that should assist in maintaining the consistency of related standards. Some QoS-related IETF Request for Comments (RFC)s are , and ; both these are discussed above. The IETF has also published two RFCs giving background on QoS: , and . The IETF has also published as an informative or best practices document about the practical aspects of designing a QoS solution for a DiffServ network. The document tries to identify applications commonly run over an IP network, groups them into traffic classes, studies the treatment required by these classes from the network, and suggests which of the QoS mechanisms commonly available in routers can be used to implement those treatments.
