Embodiment Construction

[0024] The invention relates to the technical field of industrial communication, in particular to the fusion of information and communication technology of industrial networks. An industrial communication gateway device is proposed, which has the functions of mapping between unicast, multicast, and broadcast service packets of industrial information network and unicast and broadcast data packets at the communication transmission level, and joint compression between service packets and data packets.

[0025] The following will further describe and analyze the technical key scheme of the present invention in conjunction with the drawings disclosed in the embodiments of the invention:

[0026] 1. Business packet forwarding strategy

[0027] After receiving the data packet, the gateway device checks the packet type, and replaces the header of the downlink unicast, multicast, and broadcast data packets with the header of the broadcast data packet by filling or replacing bytes; the ...

Abstract

The invention relates to a design of industrial communication network gateway equipment. The equipment can adapt to the fusion of an industrial information communication technology, and can meet the requirement that an industrial network develops in a direction of large-scale complicated Internet of things. The gateway equipment can realize the mapping from downlink unicast, multicast and broadcast service packets of an industrial network to communication broadcast data packets and the mapping from uplink unicast and broadcast data packets to unicast service packets through a package transfer mechanism, through such a measure, the downlink equipment addressing problem can be solved in a certain extent, and the transmission bandwidth of a backbone network can be saved; meanwhile, through a compression technology, information such as fixed service in the service packets and unchanged addresses in the data packets can be combined to be compressed. Therefore the transmission bandwidth at the communication transmission layer can be saved, the communication utilization rate can be improved, and particularly, a wireless transmission technology is used.

Description

technical field [0001] The present invention relates to the technical field of industrial communication network, especially for the integration of information and communication technology of industrial communication network and the development of industrial communication network toward the Internet of Things, which has large-scale and highly complex characteristics. In order to adapt to the mapping between the unicast, multicast, and broadcast services of industrial information and the unicast and broadcast data packets of the communication transmission network, and to improve the transmission efficiency of the communication network, a gateway device suitable for industrial information communication fusion is proposed. Background technique [0002] 1. Development and changes of industrial network structure [0003] Traditional industrial networks define device access network functions. With the development of information and communication technology integration technology, ...
