Summary

This White Paper describes a comprehensive view of how Quality of Service (QoS) is handled within the MUSE architecture.

MUSE advocates the introduction of QoS into IP networks as this allows better resource utilization while at the same time it allows to serve multiple and different applications with the transport quality they actually need.

After analysing the failure of previous approaches to QoS, pragmatism, simplicity and cost-effectiveness are identified as the essential characteristics of a successful solution.

Apart from this, the solution needs to be able to offer quantitative QoS support for some services and qualitative for others, to support a retail/wholesale split in the QoS business model, to provide upstream QoS, especially across the access link, and to support multiple service edges.
