Load balancing method in wireless access network, and electronic device for performing method

A non-transitory computer-readable recording medium having recorded thereon a program including instructions that are executed by at least one processor of an electronic device to perform a method of performing load balancing in a control plane of a virtual wireless access network, the method comprising:

• obtaining a packet from a client;
• searching for session information corresponding to the packet in a local table of at least one load balancer or a global table;
• updating at least one of the local table or the global table based on at least one of whether the session information exists in the local table or whether the session information exists in the global table;
• and
• transmitting the packet to a backend server identified according to a distribution method based on the session information.

An electronic device for performing load balancing in a control plane of a virtual wireless access network, the electronic device comprising:

• a transceiver;
• memory storing one or more instructions;
• and
• at least one processor,
• wherein the one or more instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
• obtain a packet from a client through the transceiver,
• search for session information corresponding to the packet in a local table of at least one load balancer or a global table,
• update at least one of the local table or the global table based on at least one of whether the session information exists in the local table or whether the session information exists in the global table, and
• transmit the packet to a backend server identified according to a distribution method based on the session information.
