Embodiments of this application provide a load balance method and an apparatus thereof. The method may include the following steps: receiving, by a load balance node, a first service request packet from a service request end, where the first service request packet includes address information of the service request end, address information of a to-be-processed load balance instance, and a MAC address of the load balance node; determining a to-be-processed service member based on the address information of the to-be-processed load balance instance, where the to-be-processed service member is configured to process the first service request packet; and modifying the MAC address of the load balance node in the first service request packet to a MAC address of the to-be-processed service member, to obtain a second service request packet, and sending the second service request packet to a computing node to which the to-be-processed service member belongs.
