Open Platform for NFV
(OPNFV)
MANO
Vitrualised Infra. Manager (VIM): To manage resources
VNF Manager (VNFM): LCM + FCAPS: To manage services
NVF Orchestrator (NFVO): instruct VNFM and VIM for services and resources
Virtualisation at Single Machine(Server)
VM
Guest OS (running on VM)
Hypervisor
Type 1 (running directly over H/w, without Host OS)
Type 2 (part of Host Os)
Orchestrator (LCM: instantiation, scaling etc)
Host OS (Running on H/W)
Containers
Hypervisor replaced by
Container Engine
(e.g. Docker)
Guest OS not required (So leaner, faster than Hypervisor based
SDN and Networking
