    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.

    Abstract: A method for vNF chaining management includes receiving virtualized network function (vNF) information from a chaining client associated with a particular vNF. A service chaining catalog is updated based on the vNF information and chaining information is transmitted to peering vNFs of the particular vNF. The vNF information can indicate instantiation of a vNF and identify peering vNFs. Updates received from vNFs can be used to update the chaining catalog. Updated vNF information can then be sent to peering vNFs of the vNF which sent the update.

    Abstract translation: 用于vNF链接管理的方法包括从与特定vNF相关联的链接客户端接收虚拟化网络功能（vNF）信息。 基于vNF信息更新服务链目录，并将链接信息发送到特定vNF的对等vNF。 vNF信息可以指示vNF的实例化并识别对等vNF。 从vNF收到的更新可用于更新链接目录。 然后可以将更新的vNF信息发送到发送更新的vNF的对等vNF。
