1. vRNC Topology
================
The simple vRNC topology is shown below: :numref:`figure_topo`

vRNC Topology
- vRNC includes four networks: EMS\_network, CTRL\_network,
Intermedia\_network and extermedia\_network;
- vRNC includes four node types: MM, LB, CM and DM;
- MM: Stands for Maintain Module, which links to EMS\_network,
CTRL\_network and extermedia\_network. It composes of active vdu and
standby vdu.
- CM: Stands for Control Module, which links to CTRL\_network and
intermedia\_network. All CM nodes form resource pool and each node
composes of active vdu and standby vdu.
- DM: Stands for Data Module, which links to CTRL\_network and
intermedia\_network. All DM nodes form resource pool and each node is
a vdu.
- LB: Stands for LineCard Module, which links to CTRL\_network and
intermedia\_network and extermedia\_network. All LB nodes form
resource pool and each node is a vdu.
2. vRNC Definition
==================
The files dependency and correspoding specificaiton of vRNC definition
are shown below: :numref:`figure_def`

vRNC Definition
- TOSCA\_definition\_1.0.yaml should be the lastest version, which is
updated by tosca-parser community, but some keywords (such as
substitution\_mappings) in the correspoding standard of
"TOSCA-simple-profile-YAML-v1.0" is not supported.
- TOSCA\_nfv\_definition\_1.0.yaml is a new file, and not implemented
in code, and the correspoding standard of
"tosca-nfv-v1.0-wd02-rev02" is not complete now.
