We propose a SDN-based architecture for distant points in- terconnection through an overlay network. The main goal of the overlay network is to provide with resilient and high- performance interconnection between its nodes, without the need of changing nor handling Internet routers. Our pro- posed architecture benets from the advantages inherited from SDN such as simplicity of management and ow-level Trac Engineering capabilities. In particular, our approach allows to build the overlay network without any tunnelling technology, which promises to provide a gain in terms of performance, and to ease deployment and management. In addition, we address one of the challenges of SDN, by dis- cussing a possible approach for active monitoring in the pro- posed SDN-overlay architecture.
