Abstract

Control planes for global carrier networks should be programmable and scalable. Neither traditional control planes nor new SDN-based control planes meet both of these goals. Here we propose a framework for recursive routing computations that combines the best of SDN (programmability through centralized controllers) and traditional networks (scalability through hierarchy) to achieve these two desired properties. Through simulation on graphs of up to 10,000 nodes, we evaluate our design's ability to support a variety of unicast routing and traffic engineering solutions, while incorporating a fast failure recovery mechanism based on network virtualization.
