Abstract: The present disclosure provides methods for shunting clustered gateways, which relate to the field of computer technologies, and in particular, relate to the technical field of data transmission. A specific implementation solution is: in response to receiving a first packet sent by a target internal network machine, a first hash value is acquired, wherein the first hash value is generated by a shunt of a public network gateway cluster, and the shunt is configured to perform a hash calculation on the first packet based on a pre-configured port dictionary; a target gateway machine is selected from the public network gateway cluster according to the first hash value; and the first packet is sent to the target gateway machine.

Abstract: The present disclosure discloses an electric border gateway device which adopts the blockchain technology to implement communication authentication and data transmission encryption at the gateway. As a device for sinking and processing local information, the border gateway device may build not only a local blockchain network with a variety of local electric sensing terminal devices, but also a regional blockchain network with other border gateways and electric management platforms. As a critical node of these two types of blockchain, the border gateway may enable the authentication of identity legality between electric sensing terminal devices, the critical data storage in the blockchain ledger, the deployment and implementation of blockchain transaction by control and coordinated functions, and the safe and reliable data interaction. The present disclosure also discloses a method for chaining and storage of sensing data based on the electric border gateway device.
