Abstract

The invention relates to a reserved bandwidth allocation method based on a dynamic network in a high-speed industrial bus communication system. According to the bandwidth allocation method and device under the dynamic network disclosed by the invention, bandwidth resources are flexibly allocated to the nodes according to the types of the nodes under the dynamic network. The high-speed industrial communication system is mainly used for solving the problems that a traditional bus in an industrial field is low in bandwidth, cannot bear real-time and non-real-time at the same time and is complex in network structure, and can support IPV6 address communication, time-triggered industrial control communication, TSN. And security mechanisms such as white list, deep detection and data encryption can be supported.

Description

technical field [0001] The invention belongs to the field of industrial control and communication, in particular to a dynamic network-based reserved bandwidth allocation method and device in a high-speed industrial bus communication system. Background technique [0002] The current industrial bus system mainly includes fixed network and dynamic network. The number of nodes in the network is fixed, the logical address (such as MAC, IP address) is fixed, the physical position on the bus is fixed, and the network that does not allow random addition and deletion of nodes during operation is called a fixed network. Correspondingly, the number of nodes in the network is not fixed, the address is not fixed, and the network that allows nodes to join and exit during operation is called a dynamic network. [0003] The current mainstream industrial bus system includes Controller Area Network (CAN) bus and Power Link. Among them, for bandwidth allocation, CAN bus only allocates communi...
