Abstract

We introduce a framework for provisioning end-toend (E2E) managed video services over a multi-domain SDN, where different domains may be operated by different network providers. The proposed framework enables efficient dynamic management of network resources for network providers and ability to request the desired level of quality of experience (QoE) for end users. In the proposed fully-distributed E2E service framework, controllers of different domains negotiate with each other for the service level parameters of specific flows. The main contributions of this paper are a framework to provide E2E video services over multi-domain SDN, where functions that manage E2E services can collaborate with functions that manage network resources of respective domains, and a procedure for optimization of service parameters within each domain. The proposed framework and procedure have been verified over a newly developed large-scale multi-domain SDN emulation environment.
