Abstract: Embodiments of the present invention provide a packet processing method and a device. The method includes: receiving a data packet that is generated and sent by a destination device after the destination device receives a first interest packet that is forwarded by a source device via the forwarding node, where the data packet carries a content name that is the same as a content name of content requested by using the first interest packet; when forwarding the first interest packet, generating, a PIT entry corresponding to the first interest packet in the PIT; and when determining that the data packet carries a second interest packet, matching the content name carried in the data packet with a content name in the PIT entry, and forwarding the data packet to the source device according to a port in the matched PIT entry.

Abstract: A topology structure discovery method and device. The topology structure discovery method includes: a controller acquiring topology structures among N routers; according to the topology structures, the controller obtaining routing tables respectively corresponding to each router, and respectively sending corresponding routing tables to each router, wherein the routing tables comprise at least one kind of routing information between the router and other N−1 routers and routing information between the router and the controller, so that the controller can obtain the topology structures of the whole network and calculate the router capable of obtaining the optimal path according to the topology structures of the whole network, thereby improving the utilization efficiency and the throughput of the network.
