Abstract:
This paper presents and discusses a framework for end-to-end Quality-of-Service in a network operator environment. We focus on the inter-operator segment. Contrary to usual approaches, we consider that, in the current state-of-the-art, the interdomain QoS problem complexity resides on the business relations between administrative domains. Therefore, we attempt to decouple the technical problem of providing end-to-end traffic assurances from the business problem of setting up partnerships. We combine the two aspects to build a framework that allows a smooth integration of the inter-domain, the intra-domain and the access segments. We also provide an IntServ-over-DiffServ architecture that is able to cope with mobility scenarios.
