Abstract: Correlation of information related to network operations may be useful in many communication systems. For example, certain wireless communication networks may benefit from alarm correlation in network function virtualization environments. A method can include correlating alarms within a lower layer of a network function virtualization environment. The method can also include forwarding at least one of the correlated alarms to an entity managing an upper layer of the network function virtualization environment for further correlation with upper layer alarms.
