US Patent 10033805 Spanning tree approach for global load balancing

A device may receive first data center information associated with first data centers in a first region. The device may receive second data center information associated with second data centers in a second region that is different from the first region. The device may generate a spanning tree based on the first data center information and the second data center information. The spanning tree may be associated with exchanging metrics associated with the first data centers and the second data centers, and may be used to exchange the metrics between the device and other devices included in the first data centers or the second data centers. The device may exchange the metrics with the other devices based on the spanning tree.
