NFV open source projects.

Project	Description
OpenStack [28]	OpenStack allows the management of virtualized resources such as virtual disks, computational nodes and networks. OpenStack addresses the management paradigm of the ETSI MANO NFV architecture.
OpenBaton [29]	OpenBaton is an ETSI NFV compliant NFVO. OpenBaton has a modular implementation allowing the integration of other software modules without having to modify or understand its core implementation. OpenBaton supports a plugin system to incorporate virtual infrastructure managers, such as Openstack.
OpenMano [30]	OpenMANO is an approach to the management and orchestration of ETSI NFV standardization. However, although OpenMano allows the definition of network services and their instantiation and deletion, it does not provide a virtual network function manager.
