Resource-Efficient and Availability-Aware Service Chaining and VNF Placement with VNF Diversity and Redundancy

To establish a network service in network functions virtualization (NFV) networks, the orchestrator addresses the challenge of service chaining and virtual network function placement (SC-VNFP) by mapping virtual network functions (VNFs) and virtual links onto physical nodes and links. Unlike traditi...
