An SDN-based architecture for Network-as-a-Service

Abstract

Network-as-a-Service (NaaS) is a cloud-based service model that offers on-demand network connectivity and the provisioning and management of network services. However, the actual orchestration of dynamically allocating underlying resources to customer requirements is not trivial. In this paper, we propose an SDN-based approach to support the NaaS model. We implement a proof-of-concept (PoC) on a physical testbed and validate it through experimental performance evaluation.
