IPv6 Address Assignment and Management Mechanism for Heterogeneous Industrial Networks

The new manufacturing production model puts forward the demand for the integration of industrial IT networks and OT networks. The proposal of TSN and DetNet standards makes it possible to converge IT and OT. In the future, TSN and DetNet will combine to become a new industrial network paradigm, making industrial heterogeneous networks a converged and interconnected IP-supporting network. Therefore, it is necessary to perform unified addressing on industrial heterogeneous networks to support indiscriminate addressing and communication between devices. Since DHCP is not suitable for industrial network scenarios, this paper proposes an IPv6 address assignment and management mechanism, which assigns specific IPv6 addresses to industrial network devices based on their characteristic information, and uses the NETCONF protocol to uniformly manage the configuration information during the address assignment process. The mechanism proposed in this paper assigns IPv6 addresses for industrial IP networks and non-IP networks uniformly, achieving IPv6-based undifferentiated addressing and laying a foundation for the seamless integration and fusion of industrial networks and the Internet.
