The key feature is immediate notification of -unavailability of virtualized resources from VIM, to support failure recovery, -or failure avoidance of VNFs running on them. Requirement survey and development -of missing features in NFVI and VIM are in scope of this project in order to -fulfil requirements for fault management and maintenance in NFV. - -The purpose of this requirement project is to clarify the necessary features of -NFVI fault management, and maintenance, identify missing features in the current -OpenSource implementations, provide a potential implementation architecture and -plan, provide implementation guidelines in relevant upstream projects to realize -those missing features, and define the VIM northbound interfaces necessary to -perform the task of NFVI fault management, and maintenance in alignment with -ETSI NFV [ENFV]_. - -Problem description -------------------- - -A Virtualized Infrastructure Manager (VIM), e.g. OpenStack [OPSK]_, cannot -detect certain Network Functions Virtualization Infrastructure (NFVI) faults. -This feature is necessary to detect the faults and notify the Consumer in order -to ensure the proper functioning of EPC VNFs like MME and S/P-GW. - -* EPC VNFs are often in active standby (ACT-STBY) configuration and need to - switch from STBY mode to ACT mode as soon as relevant faults are detected in - the active (ACT) VNF. - -* NFVI encompasses all elements building up the environment in which VNFs are - deployed, e.g., Physical Machines, Hypervisors, Storage, and Network elements. - -In addition, VIM, e.g. OpenStack, needs to receive maintenance instructions from -the Consumer, i.e. the operator/administrator of the VNF. - -* Change the state of certain Physical Machines (PMs), e.g. empty the PM, so - that maintenance work can be performed at these machines. - -Note: Although fault management and maintenance are different operations in NFV, -both are considered as part of this project as -- except for the trigger -- they -share a very similar work and message flow. Hence, from implementation -perspective, these two are kept together in the Doctor project because of this -high degree of similarity. - -.. - vim: set tabstop=4 expandtab textwidth=80: -- cgit 1.2.3-korg
