Software-Defined Networking for Transport Networks

Software-Defined Networking (SDN) is poised to revolutionize packet switched networks globally. Yet, to reach its full potential, SDN must include the transport links interconnecting the locally switched networks. By including all layers of the network protocol stack, true end-to-end optimization of packet flows by a centralized controller can finally be realized. This iBook discusses the why and how of extending SDN to the transport layer, including examples of real-world use cases.
