Dynamic end-to-end service-level negotiation over multi-domain software defined networks

We introduce a dynamic end-to-end (E2E) servicelevel management framework, which enables quality of experience to end users and efficient and flexible management of network resources for service providers, over a multi-domain SDN. In the proposed fully-distributed E2E service management framework, controllers of different domains negotiate with each other for the service level parameters of a specific service request. The main contribution of this paper is an automated dynamic E2E service-level negotiation procedure, where functions that manage E2E services can collaborate with functions that manage network resources of respective domains. The proposed framework and procedures have been verified over a large-scale multi-domain SDN emulation environment.
