On Credibility-Based Service Function Chain Deployment [PDF]
IEEE Open Journal of the Computer Society, 2021 With the advancements of Software Defined Networking and Network Function Virtualization technologies, users can access the software-based service function chain (SFC), which is composed of multiple sequential virtual network function (VNF) nodes. Although SFC is more flexible and adaptive in terms of design and deployment, the security risks should ...
