Decentralizing SDN's Control Plane

Contributors: Bruno Nunes Astuto and Thierry Turletti.

Motivated by the internets of the future that will likely be considerably larger in size as well as highly heterogeneous and decentralized, we sketched out  a framework aiming to enable not only physical, but also logical distribution of the Software-Defined Networking (SDN) control plane. This framework will accomplish network control distribution by defining a hierarchy of controllers that can “match” an internet’s organizational– and administrative structure. The main idea is to delegate control between main controllers and secondary controllers in order to accommodate administrative decentralization and autonomy. This work has been presented in a short paper at the IEEE LCN conference [22] .
