Abstract
The present application discloses a flow forwarding method, device, and system. The method includes: receiving, by an edge node, an intelligent routing service request packet, and the packet includes a constraint condition required for establishing the intelligent routing service; if the edge node does not find, in a flow table, a corresponding matching flow table entry of characteristic information, sending, by the edge node, a first message to a controller, where the first message includes identification information of the edge node and the characteristic information and the edge node is an ingress edge-node or an egress edge-node that receives the packet; receiving, a first flow table entry sent by the controller, where the first flow table entry is generated according to the first message and meets the constraint condition; and processing, according to the first flow table entry, a packet sent by the user side device.
