Classification: CPC H | IPC H

Claim 8:
9. A traffic flow processing apparatus, used in a controller, comprising:
a processor; and
a non-transitory computer-readable storage medium coupled to the processor and storing programming instructions, that when executed by the processor, instruct the processor to:
generate and configure first configuration information for a first edge node, wherein the first edge node is configured to use the first configuration information to: replicate a data packet comprised in a received traffic flow to obtain a first data packet and a second data packet; output, to a first relay node, the obtained first data packet; and output, to a second relay node, the obtained second data packet;
generate and configure second configuration information for the first relay node, wherein the first relay node is configured to use the second configuration information to: replicate the first data packet to obtain a third data packet and a fourth data packet; output, to the second relay node, the obtained third data packet; and output, to a second edge node, the obtained fourth data packet or a fifth data packet received from the second relay node, whichever is obtained or received first, wherein the fifth data packet is replicated by the second relay node using the second data packet received from the first edge node; and
generate and configure third configuration information for the second edge node, wherein the second edge node is configured to use the third configuration information to obtain a data packet from the first relay node or a data packet from the second relay node, whichever is received first, and the second relay node is not on a link from the first edge node to the second edge node via the first relay node.
