Embodiment Construction

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] In the SDN-based WIA-PA field network / IPv6 backhaul network joint scheduling method, both the IPv6-based IPv6 backhaul network and the WIA-PA network are centrally controlled and scheduled by a joint controller. The specific implementation process is as follows:

[0038] 1. Description of joint scheduling network architecture:

[0039] figure 1 It is a joint scheduling network architecture diagram, which is optimized for the characteristics of the industrial network, so that a single SDN controller can manage the entire industrial network in conjunction with the WIA-PA network manager, and the WIA-PA network located in different regions through IPv6 Support is provided for the scheduling of data streams transmitted across the backhaul network. Figure 6 It is a schematic diagram of joint scheduling.

[0040] The joint scheduling a...

Abstract

The invention relates to an SDN-based WIA-PA field network / IPv6 backhaul network joint scheduling method, belonging to the technical field of industrial networks. This method aims at the problem of data interaction between multiple WIA-PA networks and between WIA-PA networks and IPv6 backhaul networks. According to the characteristics and application requirements of WIA-PA networks, it is based on IPv6 backhaul networks. The scheduling function of WIA-PA data flow in the IPv6 backhaul network is added, and the joint control function supporting WIA-PA network manager is added to the SDN controller. The present invention not only realizes the joint scheduling of the IPv6 backhaul network and the WIA-PA network cross-network data flow, but also performs fine-grained identification on the WIA-PA network data flow, and realizes the bandwidth guarantee of the end-to-end cross-network data flow.

Description

technical field [0001] The invention belongs to the technical field of industrial networks, and relates to an SDN-based WIA-PA field network / IPv6 backhaul network joint scheduling method. Background technique [0002] The industrial backhaul network is a transmission network between a wide area network (such as a wide area network based on IPv6 / IPv4 technology) and an industrial field network (such as a WIA-PA network), and generally belongs to a medium-sized network. The industrial backhaul network based on IPv6 technology adopts IPv6 protocol for network addressing and transmission to solve the transmission problem of industrial field network accessing IPv6 / IPv4 WAN or Internet. [0003] IPv6 technology is a new generation of network technology proposed to solve the problem of exhaustion of network addresses currently faced by IPv4 networks. The IPv6 network has a huge network address space, its 128-bit address length is four times the length of the IPv4 address, and the ...
