A SYSTEM FOR TRANSLATION-BASED REAL-TIME INCONSISTENCY DETECTION IN NETWORK FUNCTIONS VIRTUALIZATION (NFV)

摘要

A method, system and apparatus are disclosed. According to one or more embodiments, a detection node (14) in communication with a network function virtualization, NFV, system operating a NFV stack that is logically separable into a plurality of levels including a first level and a second level is provided. The detection node (14) includes processing circuitry (32) configured to: translate an executed first level event sequence to at least one translated second level event sequence, and compare the at least one translated second level event sequence to an executed second level event sequence to at least in part detect inconsistencies between the at least one translated second level event sequence and the executed second level event sequence where the executed second level event sequence and the executed first level event sequence being part of a multi-level sequence flow.
