SDN-based WIA-PA field network/IPV6 backhaul network joint scheduling method

摘要

The present invention relates to an SDN-based WIA-PA field network/IPv6 backhaul network joint scheduling method, which belongs to the technical field of industrial networks. Specific to the currently existing problems on data interaction among multiple WIA-PA networks and between the WIA-PA network and an IPv6 network, the method implements a scheduling function for a WIA-PA data stream in the IPv6 backhaul network and adds a joint control function for supporting a WIA-PA network manager in an SDN controller based on the IPv6 backhaul network according to the self-characteristics and application requirements of the WIA-PA network. The present invention not only implements the joint scheduling of a cross-network data stream for the IPv6 backhaul network and the WIA-PA network, but also enables the fine-grain recognition specific to the WIA-PA network data stream to implement the bandwidth guarantee for the end-to-end cross-network data stream.
