SERVICE FUNCTION CHAINING BRANCHING

机译:服务功能分行

摘要

A system comprising a plurality of service nodes, a controller and a network device in communication with the controller. Each of the plurality of service nodes is configured to support one or more service functions to establish a service function chain that includes a plurality of service functions to be performed by routing traffic among the plurality of service nodes. The controller is configured to generate provisioning information for the service function chain. The provisioning information includes at least one condition upon which a service function reclassification or branching operation is to be performed by at least one service node. The network device is in communication with the controller, and is configured to distribute the provisioning information for the service function chain to the plurality of service nodes using a distributed routing protocol.
