SFCaaS: Service function chains as a service in NFV environments
ITU Journal on Future and Evolving Technologies, 2022 With the growing deployment of emergent technologies like software-defined networking, network services are expected to be revolutionized. In this paper, we investigate offering Service Function Chains as a Service (SFCaaS) in NFV environments. We describe the potential business model to offer such a service and then we address the service function ...

Reliability‐aware service chaining mapping in NFV‐enabled networks
ETRI Journal, 2019 Network function virtualization can significantly improve the flexibility and effectiveness of network appliances via a mapping process called service function chaining. However, the failure of any single virtualized network function causes the breakdown

Scalable Architecture for Service Function Chain Orchestration [PDF]
2015 Fourth European Workshop on Software Defined Networks, 2015 Network Function Virtualization (NFV) enables to implement network functions in software, high-speed packet processing functions which traditionally are dominated by hardware implementations. Virtualized Network Functions (NFs) may be deployed on generic-purpose servers, e.g., in datacenters.
