| Abstract
|
While there has been significant progress in the definition of
Quality of Service (QoS) architectures for internet networks, there
are a number of aspects of QoS that appear to need further
elaboration as they relate to translating a set of tools into a
coherent platform for end-to-end service delivery. This document
highlights the outstanding architectural issues relating to the
deployment and use of QoS mechanisms within internet networks, noting
those areas where further standards work may assist with the
deployment of QoS internets.
This document is the outcome of a collaborative exercise on the part
of the Internet Architecture Board.
