This invention provides a method, apparatus, electronic device, and readable medium for operator management of a
virtual network (VLAN). Applied to a network controller, the VLAN communicates with at least one network operator, obtains the user's priority relationship with at least one network operator, and acquires the communication connection status between the VLAN and the network operator through a load balancer. When the VLAN receives first traffic sent by any network operator, it determines a target network operator among the at least one network operator based on the first traffic, the communication connection status, and the priority relationship. It obtains the address of the target network operator through the
Domain Name System (DNS) and forms a target mapping session on
the Internet gateway based on the address. The target mapping session is used to determine the target address of the second traffic when the VLAN sends second traffic related to the first traffic. The target address is the address of the target network operator, providing customers with multi-operator link exits and performing link health checks.
