Software-Defined Network (SDN) is expected to have a significant impact on future networking. Although exciting progress has been made toward realizingSDN, application of this new networking paradigm in the future Internet to support end-to-end QoS provisioning faces some new challenges. The autonomous network domains coexisting in the Internet and the diverse user applications deployed upon the Internet call for a uniform Service Delivery Platform (SDP) that enables high-level network abstraction and inter-domain collaboration for end-to-end service provisioning. However, the currently available SDN technologies lack effective mechanisms for supporting such a platform. This chapter presents an SDP framework that applies the Networkas- a-Service (NaaS) principle to provide network abstraction and orchestration for end-to-end service provisioning in SDN-based future Internet. In order to address the new challenges brought in by resource abstraction enabled by NaaS to system modeling and analysis for QoS evaluation, a profile-based analysis method developed based on the network calculus theory is also presented in this chapter.
