Summary

MUSE has developed a business model that allows to describe real life actors by a combination of different generic roles. The DSL Forum already defined the roles of a Network Access Provider, Regional Network Provider, Network Service Provider, and Application Provider. The MUSE model has a finer granularity than the one currently used by the DSL Forum in order to support further unbundling of the value chain, and has identified two new roles, the Packager and Connectivity Provider.

The present document gives the definition for each of these roles. It analyses the consequences for network configuration and scalability, as well as requirements for the definition of some new control and management interfaces. A detailed analysis is made of the technical responsibilities for the AAA architecture, IP address allocation, QoS framework and ACS.
