Architecture for integrating vertical customer’s programmability control of network functions and connectivity in a slice-as-a-service schema

Abstract Network slicing will permit offering to vertical customers tailored end-to-end logical networks in an on-demand fashion, on top of a common telecom infrastructure, achieving Slices-as-a-Service (SlaaS) business model. This is possible due the progressive introduction network softwarization techniques, such as programmability and virtualization, into existing operational networks, enabling dynamic flexible provision slices. Those could require control not only functions composing service, but also connectivity among them, e.g., for influencing paths steering traffic function instances. However, this can be problematic since decisions from one customer collide with others. One aspect yet sufficiently investigated how jointly service underlay connectivity, way that operate allocated slice if it was actually dedicated entirely them. paper explores some architectural proposition respect illustrated potential use cases provides example SlaaS customer.
