Incremental Deployment of SDN in Hybrid Enterprise and ISP Networks

David Ke Hong, Yadi Ma, Sujata Banerjee, Z. Morley Mao
2016 Proceedings of the Symposium on SDN Research - SOSR '16  
We present such a system for incremental deployment of hybrid SDN networks consisting of both legacy forwarding devices (i.e., traditional IP routers) and programmable SDN switches.  ...  Introducing SDN into an existing network causes both deployment and operational issues. A systematic incremental deployment methodology as well as a hybrid operation model is needed.  ...  Acknowledgements We would like to thank Ying Zhang, Jeongkeun Lee, Joon-Myung Kang, Mario Sanchez, Alvin AuYoung and anonymous reviewers for useful feedback and discussions.  ...

MPLS based hybridization in SDN

Yash Sinha, Siddharth Bhatia, Virendra S Shekhawat, G.S.S. Chalapathi
2017 2017 Fourth International Conference on Software Defined Systems (SDS)  
The new paradigm of Software Defined Networking (SDN) although has great potential to address the complex problems presented by enterprise networks, it has its own deployment and scalability issues.  ...  In legacy networks, MPLS architecture closely resembles SDN paradigm in terms of separation of control and data planes, flow-abstraction etc.  ...  Automated SDN deployment methods [3] focus on automating SDN switch installation in hybrid networks to minimize risk of errors in manual configuration and reduce operational costs.  ...
