Multi-domain Software Defined Network Provisioning

Multi-domain provisioning can be a time consuming and complex process, especially when the provisioning occurs between different administrative domains. The Software Defined Networking (SDN) paradigm provides a flexible programmatic solution that can be used to improve network management and control. SDN can be used to implement automated flexible provisioning in multi-domain networks, and provides an opportunity to implement improved processes for automated provisioning between different administrative domains. In this paper, a SDN-based framework is proposed for multi-domain provisioning. The BGP UPDATE message is used to pass provisioning related information between the SDN domains. An application prototype was developed to test the framework with a Bandwidth on Demand use case. The evaluation shows that the framework behaved as expected and the application prototype successfully carried out multi-domain provisioning between different administrative domains.
