High performance SDN hardware architectures and their uses in the evolving transport network

Summary form only given. L2/L3 forwarding requirements determine what Programmable (SDN) Networking means for transport networks. The end of Moore's law (16-7 nm silicon) and optical channel capacity (Shannon-Nyquist limits) pose constraints on hardware architectures. We look at how programmable L2/L3 SDN maps to technology contrained physical architectures.
