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 this application disclose a route advertisement method and a device, to improve efficiency of generating a route advertisement message. The method is applied to a network including a first network device and a second network device, and the first network device and the second network device establish a user datagram protocol UDP-based border gateway protocol BGP connection. The method includes: The first network device obtains one or more route sending groups, where each route sending group includes one or more pieces of route information; the first network device separately generates at least one route advertisement message based on each route sending group, the route advertisement message includes the one or more pieces of route information in the route sending group corresponding to the route advertisement message; and the first network device sends the route advertisement message to the second network device through the BGP connection.

Abstract: This application provides a route refresh method, apparatus, and system, and relates to the field of communication technologies. In solutions provided in this application, a first network device can send a plurality of first routes to a second network device in a parallel transmission manner, and can send an end indication after determining that the second network device receives the plurality of first routes. Therefore, it can be ensured that in a parallel transmission scenario, the end indication does not reach the second network device earlier than the first routes. This can avoid a problem that a service flow is interrupted because the second network device untimely ages a route that is not refreshed in a routing table.

Abstract: A method and an apparatus for establishing a BGP peer, a device, and a system. A first network device sends a first packet to a second network device in a UDP manner, where the first packet is used to establish a BGP peer with the second network device; and if the first network device can receive a second packet sent by the second network device in the UDP manner, the first network device establishes a BGP peer relationship with the second network device in response to the received second packet.
