Abstract
A load balancing apparatus stores a transfer rule in which a path control identifier for identifying a path for a message sent from a client device is associated with relay device information for specifying a relay device that creates the path control identifier. When receiving a message from the client device, the load balancing apparatus determines whether the message contains the path control identifier. If the load balancing apparatus determines that the path control identifier is contained, the load balancing apparatus specifies, from the transfer rule, relay device information with which the path control identifier is associated and then sends the message to a relay device that is specified by the specified relay device information. In contrast, if the load balancing apparatus determines that the path control identifier is not contained, the load balancing apparatus sends the message to the relay device specified in accordance with a predetermined condition.
