WoMANO is an open source project that provides a practical realization of the Network Function Virtualization Management and Orchestration(NFV MANO)from the perspective of Telecommunication Operator. The building of WoMANO conforms to the ETSI's NFV ISG standardization. WoMANO focuses on network service orchestration (NFVO) and virtual resource management(NFVI+VIM), and integrates the open source cloud computing platform OpenStack native interface successfully, and also integrates the open source capability component(including Ceph,Opendaylight,KVM) and VNF systems(OpenEPC, ClearWater). It implements the orchestration, deployment, reliability and elastic extension of VoLTE network services, it successfully explores operation mode of network services under the environment of NFV and verifies the technical feasibility of virtual network function (VNF) carried on the cloud computing platform. It provides the reference for China Unicom to carry out network infrastructure upgrades, and simplified network operating mode.

WoMANO provides three software modules:

1. Womano: it realizes the network service orchestration (NFV-O), it can create a complex virtual network environment. It interfaces with the virtual infrastructure manager (VIM) and provids the upstream interface for providing NFV services, such as creating or deleting virtual network functions.

2. WoVIM: it realizes virtual resource management, it interfaces with the computing nodes and controller, provids compute and network capabilities, and the deployment of virtual machines. It externally offers the upstream interfaces, you can enhance the function of the cloud computing services, such as creating, deleting, managing the images, instances and network.
