4. 1. vRNC Topology

The simple vRNC topology is shown below: Fig. 4.1

Fig. 4.1 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.

4.1. 2. vRNC Definition

The files dependency and correspoding specificaiton of vRNC definition are shown below: vRNC Definition

Fig. 4.2 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.
