IPv6 and 5G based Architecture for IIoT
draft-tang-iiot-architecture-00
Abstract
As the foundation of the current new round of industrial revolution,
the Industrial Internet of Things (IIoT) based on Cyber-Physical
Systems (CPS) [smart-factory] has become the focus of research in
various countries. In the entire development stage of IIoT, one of
the key issues is the standardization of the IIoT architecture. With
the development of intelligent manufacturing technology, the number
of the IIoT devices will increase sharply, and a large amount of data
will be generated in the industrial manufacturing process. However,
traditional industrial networks cannot meet the IIoT requirements for
high data rates, low latency, massive connections, interconnection
and interoperability. The current IIoT architectures also have
various limitations: mobility, security, scalability, and
communication reliability. These limitations hinder the development
and implementation of IIoT. As a network layer protocol, IPv6 can
solve the problem of IPv4 address exhaustion. As a high-speed, low-
latency wireless communication technology, 5G has great potential in
promoting IIoT. In order to solve the above problems, this draft
proposes an IIoT architecture based on IPv6 and 5G. It can provide
high-speed, low-latency communication services, provide massive
connectivity, mobility, scalability, security and other features for
industrial device. And the architecture can provide generalized,
refined, and flexible network services for devices outside the
factory. And an information model is defined to standardize the
representation of information in IIoT. Finally, the draft discusses
security challenges and recommendations in IIoT.
