The paper discusses the provision of differentiated guarantees to a population of users who share a network with different requirements for their connections. The basic concept underlying the proposed solutions is the required availability of the connections, both in the long term and during the period covered by the Service Level Agreement. An adequate metric for the latter is provided by the interval availability. The paper discusses how Markov chains may be used to model interval availability during the SLA period.
