Abstract: A packet forwarding method and apparatus, and a communication network, related to the field of communication technologies. In the solutions provided, a controller may obtain a correspondence between an application-aware identifier of a service flow and a network service required for transmitting the service flow, and deliver the correspondence to a network device. Further, when identifying the service flow as a service flow indicated by the application-aware identifier, the network device may directly forward a packet of the service flow by using the corresponding network service. The controller may establish and deliver the correspondence between the application-aware identifier and the network service, so that the network device can directly forward the service packet of the service flow based on the correspondence. Therefore, flexibility of forwarding the service packet is effectively improved.

Abstract: Embodiments of the present invention provide a Multiprotocol Label Switching traffic engineering tunnel establishing method and device. A tunnel establishing method includes: receiving, by a second routing device, an identifier, which is sent by a first routing device, of an MPLS TE tunnel from a first VPN instance to a second VPN instance; acquiring, by the second routing device according to the identifier, path information of the MPLS TE tunnel from the first VPN instance to the second VPN instance; and establishing an MPLS TE tunnel from the second VPN instance to the first VPN instance according to the acquired path information. Therefore, forward and reverse bidirectional tunnels are co-routed or partially co-routed, thereby solving a problem caused by non-co-routing during BFD.

Abstract: In embodiments of this application, the network node may receive a first data packet, where the first data packet carries first traffic feature data of a first data flow to which the first data packet belongs. The network node may determine a data forwarding policy based on the first traffic feature data. Because the data forwarding policy includes a policy used when the network node forwards a data packet included in the first data flow, the network node may forward the data packet based on the data forwarding policy. It may be learned that, in this solution, there is no need for a controller to determine the forwarding policy and the network node to execute the forwarding policy. Instead, the network node may learn of the traffic feature data of the transmitted data flow in real time, and determine and use the data forwarding policy in a timely manner.

Abstract: A first network device includes a processor and a memory having instructions stored thereon that, when executed by the processor, cause the first network device to: obtain a first virtual private network (VPN) route sent by a second network device. The first VPN route includes first identification information that uniquely identifies a first VPN instance in the second network device. The first network device is also caused to generate a second VPN route according to a second VPN instance accessing a third network device and the first VPN route. The second VPN route carries second identification information and routing information of the first VPN route. The second identification information uniquely identifies the second VPN instance in the third network device. The first identification information is different from the second identification information. The first network device is further caused to send the second VPN route to the third network device.
