Method and apparatus for communication between private networks, electronic device and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a memory, communicatively connected to the at least one processor;
• wherein, the memory, storing instructions executable by the at least one processor, the instructions, when executed by the at least one processor, cause the at least one processor to perform operations, the operations comprising:
• receiving a communication request sent by a first sub-instance provided in a first private network, the first sub-instance being created based on that the first private network initiates a network registration request to a master instance;
• determining a second private network as a destination based on the communication request;
• and
• sending the communication request to the second private network through a second sub-instance provided in the second private network, the second sub-instance being created based on that the second private network initiates a network registration request to the master instance, wherein the first private network, the second private network, and a cloud enterprise network provided with the master instance forms a star topology centered on the cloud enterprise network,
• wherein a process of creating the first sub-instance comprises:
• receiving the network registration request initiated by the first private network;
• determining a first communication address of the first private network based on the network registration request, comprising:
• identifying the first communication address of the first private network included in the network registration request based on a border gateway protocol;
• returning a sub-instance creation instruction through the first communication address;
• and
• controlling the first private network to create the first sub-instance based on the received sub-instance creation instruction.

A non-transitory computer readable storage medium, storing computer instructions, the computer instructions, when executed by a processor, cause the processor to perform operations, the operations comprising:

• receiving a communication request sent by a first sub-instance provided in a first private network, the first sub-instance being created based on that the first private network initiates a network registration request to a master instance;
• determining a second private network as a destination based on the communication request;
• and
• sending the communication request to the second private network through a second sub-instance provided in the second private network, the second sub-instance being created based on that the second private network initiates a network registration request to the master instance, wherein the first private network, the second private network, and a cloud enterprise network provided with the master instance forms a star topology centered on the cloud enterprise network,
• wherein a process of creating the first sub-instance comprises:
• receiving the network registration request initiated by the first private network;
• determining a first communication address of the first private network based on the network registration request, comprising:
• identifying the first communication address of the first private network included in the network registration request based on a border gateway protocol;
• returning a sub-instance creation instruction through the first communication address;
• and
• controlling the first private network to create the first sub-instance based on the received sub-instance creation instruction.
