Abstract

The paper proposes a novel approach to service differentiation using both 'classical' QoS parameters and novel resilience-oriented QoR (Quality of Resilience) parameters. In this concept, two network states are defined, 'fully operational' and 'after failure', enabling the operators to define precisely the QoS guarantees before and after a failure occurrence, and to distribute information about failure severity to a customer/user. As such, a combined QoS/QoR approach can be seen as a kind of an 'insurance' for the customer, i.e. sharing the risk of a failure occurrence and enabling selective treatment of individual services. In the 'after failure' state, the failure is unverifiable for the user, and a service with a lower QoS guarantee is provided at possibly reduced costs.
