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.
