Therefore, the address of its own system is in the form of 1.YY, that is, the network identifier is 1, and other systems have similar networks that are also 1.YY. The two systems have the requirement to communicate with each other after they have been debugged and stabilized. No network is convenient to change its network ID

Embodiments of the invention relate to a method for inter-network communication, gateway equipment and a computer storage medium. The method comprises the following steps: receiving a first message comprising a first source logical address and a first destination logical address from a first network via a first port group, wherein the first source logical address is a first internal logical address of a first device in the first network, and the first destination logical address comprises a second global network identifier configured for a second network and a second host identifier of a second device; determining a first host identifier of the first device; determining the second internal logical address of the second device in the second network; modifying the first source logical address into a first global network identifier and the first host identifier; modifying the first destination logical address into a second internal logical address; and sending the first message in which the first source logical address and the first destination logical address are modified to the second network via a second port group. Therefore, inter-network communication can be realized under the condition that logical addresses in the networks conflict.
Description
technical field [0001] Embodiments of the present disclosure generally relate to the communication field, and specifically relate to a method, a gateway device, and a computer storage medium for inter-network communication. Background technique [0002] In practical application scenarios, the communication system such as EPA bus communicates according to the logical address. The format of the logical address is XX.YY, where XX is the network identification (also known as network segment address, network segment information or network segment identification), and YY is Host ID (also known as host ID or address). Therefore, the address of its own system is in the form of 1.YY, that is, the network identifier is 1, and other systems have similar networks that are also 1.YY. The two systems have the requirement to communicate with each other after they have been debugged and stabilized. It is inconvenient for any network to change its network ID.
