Making a voice call is a typical scenario in telecommunication industry.
To make the voice calling as a NFV workload running atop OpenStack
Infrastructure, such workload consists of VNF and MANO functionality,
Telco needs to leverage a MANO to deploy corresponsding network services
Telco needs to leverage a MANO to deploy corresponding network services
along with underlying infrastructure.
In this blueprint, we deploy the voice calling workload (vIMS and Open-O,
which serves as VNF and MANO respectively) on an OpenStack infrstructure.

Network Function Virtualization(NFV) is a network architecture concept that
uses virtualization technology in Telco industry. Virtual Network Function
(VNF) is a software implementation of network functions that can be deployed
on a Network Virtualization Infrastructure(NFVI). OpenStack is a type of
NFVI.
on a Network Virtualization Infrastructure(NFVI). Virtualized Infrastructure
Manager(VIM) is responsible for controlling and managing the NFVI resources.
OpenStack is a VIM.
Running a VNF on a NFVI is a normal way to demonstrates the ability that
OpenStack supports NFV. To fulfill the goal, a MANO is needed to manage the
lifecycle of VNF and orchestrate the services.

OPEN-O is an open source MANO project.

vIMS network is a core component of deploying VoLTE services in an LTE network
and it a good candidate for showing the OpenStack deployment ability.

The workload of running vIMS on OpenStack with OPEN-O
1. Deploy 1 VM by OpenStack and install the OPEN-O
1. Deploy OPEN-O docker containers on the host
* refer to the prerequisite for the VM requirement
2. Bind the OPEN-O with OpenStack
2. Create security group and add security rules to allow icmp, tcp and ucp ports
* configure OpenStack as Virtual Infrastructure Manager(VIM) by calling
OPEN-O API, which is mainly about providing OpenStack authentication
information to OPEN-O
3. Deploy a VM on OpenStack and install Juju
3. Deploy the vIMS by OPEN-O
4. Connect Juju to OPEN-O
* set up the Juju VNFM web service developed by OPEN-O
* enable the VNFM service in OPEN-O via OPEN-O Restful API
5. Connect OPEN-O with OpenStack
* configure OPEN-O to use OpenStack as its VIM. This can be done by providing
the OpenStack authentication information to the orchestrator.
6. Deploy the vIMS by OPEN-O
* define the Network Service Descriptor(NSD) and VNF Descriptor(VNFD) to
give the overall definition for the topology
* deploy the topology by OPEN-O
* several VMs are deployed to play different roles. A Clearwater vIMS is
