Claim 5:
6. A communication method, comprising: receiving, by a transmission node, a data packet, wherein the data packet carries a number that is used to select a transmission path for the data packet; calculating, by the transmission node, a hash value based on a source Internet protocol (IP) address, a destination IP address, a source port, a destination port, a transport-layer protocol, and the number that are corresponding to the data packet; selecting, by the transmission node, based on the hash value, an egress port corresponding to the hash value to forward the data packet, wherein the data packet is a probe data packet or a service data packet; and transmitting, by the transmission node, a forward probe data packet using a second allocated bandwidth; or transmitting, by the transmission node, a backhaul probe data packet using a first allocated bandwidth; wherein the forward probe data packet is a probe data packet sent by a source node to a destination node, and the backhaul probe data packet is a probe data packet backhauled by the destination node to the source node.
