With a growing need for improved network infrastructure and technologies, which nowadays support a plethora of Internet-based services, network services providers are facing challenges in restructuring their businesses for scalability and flexibility. This thesis explores the Software-Defined Networking (SDN) paradigm and extends the state-of-the-art by contributing to push its boundaries beyond packet networks, and towards greater programmability. It begins by presenting the performance benefits that the adoption of SDN can provide, for certain packet network architectures, in comparison with more traditional management strategies. Moving further towards the fiber-optics layer, a modular control plane architecture for hybrid packet/optical data centers is presented and performance benefits are discussed.

Tackling some of the limitations of SDN, a Software-Programmed Networking (SPN) paradigm is proposed in this thesis, as an architectural solution that leverages network programmability, virtualization, and the decoupling of centralized management from distributed network control. It implements an innovative “program & compile” style to networking, while delivering a service-oriented, programmable Network-as-a-Service (NaaS) platform. A performance comparison is carried out against a state-of-the-art open-source SDN platform, and further developments incorporating cloud-based Network Function Virtualization (NFV) and Service-Function Chaining (SFC) capabilities are evaluated.
