Next Steps for the IP QoS Architecture

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.
