Method and Apparatus for Virtual Function Self-Organisation

An apparatus for virtual function self-organisation in operation of a network service in a virtual network environment managed by a Network Functions Virtualisation Management and Orchestration, NFV MANO, system, the apparatus comprising a processor and a memory, the memory containing instructions executable by the processor such that the apparatus is operative to:

• monitor processing load on a first service chain component;
• and
• if a processing load change is detected at the first service chain component:
• determine an impact of the processing load change on a second service chain component located downstream in said service chain;
• and
• notify the NFV MANO system about the impact the processing load change will have on the second service chain component in said service chain if the processing load of the second service chain component is expected to cross a threshold.
