-This project is based on the requirement proposal in “HA requirement-Chinamobile.pptx”,​ which is proposed in the initial TSC meeting. The proposal is focusing on the high availability requirements of the OPNFV platform regarding the Carrier Grade NFV scenarios. ​Some possible development of codes to meet the requirement ​may also be developed. ​+This project is based on the requirement proposal in “HA requirement-Chinamobile.pptx”,​ which is proposed in the initial TSC meeting. The proposal is focusing on the high availability requirements of the OPNFV platform regarding the Carrier Grade NFV scenarios. ​Specific ​codes to meet the requirements ​may also be developed ​later, e.g. in the subsequent integration & testing, and collaborative development projects.
  
 In many existing networks, various forms of HA have been implemented for protecting from underlying physical hardware faults and failures, such as the 1:1 or active:​standby model. Migrating network applications to a new implementation paradigm, anchored around the end-to-end NFV architecture,​ introduce new HA considerations and approaches. Hardware HA must still be managed, but now so too are the HA aspects of the virtual infrastructure,​ and the overall HA of the services provided by VNFs. In this project, we address HA requirements and solutions in 3 different perspectives,​ the hardware HA, the virtual infrastructure HA and the service HA, to be specific. ​ In many existing networks, various forms of HA have been implemented for protecting from underlying physical hardware faults and failures, such as the 1:1 or active:​standby model.

 The hardware HA can be solved by several legacy HA schemes. However, when considering the NFV scenarios, hardware failure will cause collateral damage to not only virtual infrastructures but also services running on it. Therefore, fault detection and report of HW failure from the hardware to VIM, VNFM and Orchestrator is necessary for the HA approaches in OPNFV. ​ The hardware HA can be solved by several legacy HA schemes.

-Virtual infrastructure HA addresses the high availability mechanisms for NFV infrastructures and VIM. The HA schemes Openstack now have, which provides HA for different components for Openstack (such as Nova, Quantum, and etc.), can be categorized into this class. However, considering the Carrier Grade NFV scenarios, current HA schemes ​may not be enough. Gap analysis for Openstack HA schemes ​can be done in this project. Based on the analysis, further improvement and development can be done to improve the HA schemes for the virtual infrastructure.+Virtual infrastructure HA addresses the high availability mechanisms for NFV infrastructures and VIM.

-There are several different mechanisms for the service HA. In this project, a white paper concluding these different mechanisms will be accomplished. Based on these mechanisms, we can further study what capability and interfaces OPNFV platform shall provide to the services. Therefore, API provided by the OPNFV platform to the services HA schemes should be well defined.+There are several different mechanisms for the service HA.

 In this project, we will first work on the HA requirements of Carrier Grade NFV. The requirements will include the hardware HA, the virtual infrastructure HA, and the service HA. HA API will then be well defined according to the requirements. Such API may include not only state update but also capability provision from the hardware and platform to the Orchestrator,​ the VNFM and different VNFs,  In this project, we will first work on the HA requirements of Carrier Grade NFV.

 For the service HA, studies about the current service HA schemes can be pulled out. In the meantime, API can be defined for state update and capability provision for the VNFs from the lower layers. Related interfaces may include vn-nf, vi-vnfm and or-vi. ​ For the service HA, studies about the current service HA schemes can be pulled out.
