This project aims at developing requirements for Network Functions Virtualisation Infrastructure (NFVI) fault detection and notification through the northbound interface of Virtualised Infrastructure Manager (VIM). Such notification would be sent to Virtualised Network Function Manager (VNFM) or the NFV Orchestrator (NFVO). NFVI faults include fault in compute, network and storage resources, as well as other elements of NFVI e.g. hypervisor. Faults in all elements in NFVI that affects the proper functioning of the VNFs in question shall be handled in a step-by-step fashion. In addition, requirements on VIM and its northbound interface for NFVI maintenance operation would also be developed, as its similarities with fault detection/notification feature.
The ultimate goal of this project is to realize an NFVI fault management and maintenance framework for telecom VNFs. Relevant fault events, their detection and recovery procedure, notification mechanism e.g. publish-subscribe model and other necessary features to realize the framework would be studied and requirements would be produced for relevant upstream projects. This project considers OpenStack as VIM.
