Title:
DDS-BASED CROSS-NETWORK SEGMENT COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/098040
Kind Code:
A1
Abstract:
Disclosed in the present invention is a DDS-based cross-network segment communication method, comprising: respectively establish a domain a and a domain b with different IDs on two hosts A and B in different network segments, create a publisher on the A, create a subscriber on the B, register the same data type, create the same topic, create a data writer by the A to write data, and create a data reader by the B to read data; run a sub of the domain a and a pub of the domain b on a computer C with dual network cards; the sub receives data published by the pub of the host A, and issues the received data to the sub of the host B by means of the pub to implement communication. The method can realize cross-network segment communication of hosts in different network segments in real time and reliably, and facilitates better expansion of a system network.
