Project Title : SEQUIN Deliverable D 2 . 1 - Monitoring and

SEQUIN investigates methods for providing QoS differentiated services over the IP-based networks such as the GÉANT network. Initially, the project defined a framework for supporting IP Premium service and described the procedures for establishing Service Level Agreements (SLAs) amongst networks such as GÉANT and the NRENs. In succession, SEQUIN investigates methods for monitoring the network behaviour and techniques for assessing the quality of delivered services to the end-users, i.e. NRENs. This document reviews various IP measurements methods and describes monitoring architectures that may be deployed in large-scale backbone networks. Furthermore, it provides a general framework for monitoring QoS provisioning in GEANT.
