To provide Quality of Service (QoS) guarantees today is challenging if the provider does not have full control over all the resources used. In the near future, market demand will require that one provider guarantees QoS, even if multiple providers are involved in the delivery of the service. This paper describes the on-going work to define a generic framework suitable for this situation. The framework is based on entity relationships and is complementary to existing frameworks and models. This is applicable independent of services, technologies, networks, etc. The QoS provided to the user is a function of local influence and the QoS delivered by sub-providers. The framework being developed goes into some detail regarding the interchange of information between providers.
