Abstract

Concepts and technologies are disclosed herein for message flow management for virtual networks. A processor can identify a target virtual network function instance that is to be taken offline. The processor can change a status associated with the target virtual network function instance to indicate it being taken offline. The processor can start a graceful shutdown timer to trigger shutdown of the target virtual network function instance. The processor can identify external interfaces and a peer network function that identifies the target virtual network function instance as a next hop. The processor can obtain, for the target virtual network function instance and the peer network function instance, a snapshot that identifies configuration data for the target virtual network function instance and the peer network function instance and can generate a command to trigger a shutdown of the target virtual network function instance.
