Claim Text:
1. A method of distributing data traffic in a cloud computing system including a plurality of local data centers distributed over different regions and a control center coupled to the plurality of local data centers through a network, the method comprising: detecting, by a first local data center, a heavy data traffic source region transmitting packets exceeding a given threshold among source regions where packets are transmitted from; requesting, by the first local data center, the control center to distribute packets from the detected heavy data traffic source region; searching, by the control center, for a second local data center associated with the detected heavy data traffic source region based on at least one given factor; transmitting, by the control center, a preparation command to the second local data center such that the second local data center performs a preparation procedure for processing packets inflowing into the first local data center; transmitting, by the control center, a distribution command to the first local data center when a preparation completion message is received in response to the preparation command from the second local data center; and distributing, by the first local data center, the packets, which are transmitted from the detected heavy data traffic source region, to the second local data center, according to the distribution command, wherein the detecting includes: determining whether each of the source regions is the heavy data traffic source region, based on an amount of data traffic inflowing from each of the source regions.
