This document describes D2.2 of the Internet Next Generation project. Internet Next Generation is a project performed within the context of the Gigaport programme, and is funded by many organizations within the Netherlands. Details of the Internet Next Generation project can be obtained from http://ing.ctit.utwente.nl/.
The architecture that is described within this document explains how customers of a Differentiated Services (DiffServ) network can manage the service that is provided by them, by reading and modifying QoS parameters in an interactive way. Which parameters are available and which values these parameters can take, is defined in the Service Level Specification (SLS), which is part of the Service Level Agreement (SLA). The form of management in which customers can modify the behaviour of the provided service is called Customer Service Management (CSM); the idea that customers can manage the behaviour of the provided service is not only interesting in case of DiffServ, but also in cases like Mobile IP, IP security or Virtual Private Networks (VPNs).
The scope of this deliverable is restricted to QoS management in a DiffServ environment; a subsequent deliverable will extend this work and address how service management can be performed in other environments, like IntServ / RSVP. This new deliverable will also address the problem of inter domain management.
This deliverable is strongly related to:
• the IETF work on policy based management and configuration management. The particular contribution of this deliverable is that it explicitly describes an architecture and discusses the differences between the COPS/PIBs and SNMP/MIBs approach.
• the Internet-2 QBone project, in particular the work on the Bandwidth Broker.
