Abstract: Embodiments of this application disclose a packet processing system and method, to perform network topology discovery and routing table delivery. The system includes a source node, an intermediate node, and a destination node. After receiving, from a first port, a first packet to be sent by the source node to the destination node, the intermediate node decodes the first packet to obtain a forwarding path of the packet and an identifier ID of the source node; and the intermediate node generates a first mapping relationship based on the ID of the source node and an identifier of the first port, so that when receiving a response packet of the first packet, the intermediate node may determine a sending port of the response packet based on the first mapping relationship.
