Method and system for controlling device node access in edge computing network

The invention discloses a method and a system for controlling access of equipment nodes in an edge computing network. The method comprises the following steps of: extracting network address translation (NAT) information of each equipment node in the edge computing network; determining a master computing node and a slave computing node in the edge computing network based on the NAT information; sending a network address allocation request to an NAT entity, so that the NAT entity allocates a network address to the main computing node; establishing a session channel between an edge computing network and a cloud computing platform based on the network address allocated by the main computing node; and the main computing node controls the traffic access of each equipment node in the edge computing network based on the session channel. According to the edge computing network disclosed by the invention, the main computing node is determined, so that the main computing node can realize a session mechanism with the clo
