A novel hybrid distributed-routing and SDN solution for Traffic Engineering

Capacity demands and Traffic Engineering (TE) requirements are expected to grow rapidly, and become increasingly challenging. We propose a hybrid approach that combines the benefits of Software-Defined Networking (SDN) solutions of a holistic network view to compute TE paths and resource allocation, with the benefits of distributed routing solutions featuring fast network reactions. TE paths and resource allocations are computed by a controller, then communicated using a link-state routing protocol.
