摘要： The present invention discloses a method, routing bridge, and system for sending a packet, which are applied to the field of communications technologies, and are invented to reduce a signaling overhead of a TRILL network. The method includes: receiving, by a first transit RB, a Nickname of an edge RB sent by a second transit RB; constructing, an address advertisement message, where the address advertisement message includes a virtual IP address and a virtual MAC address of the first transit RB; and sending, the address advertisement message to the edge RB according to the Nickname of the edge RB, so that the edge RB sends, after receiving the address advertisement message, a free ARP packet to a server that accesses the TRILL network through the edge RB, where the free ARP packet includes a correspondence between the virtual MAC address and the virtual IP address.

摘要： This application discloses a network and a data transmission method and apparatus, and belongs to the field of communication technologies. The network includes a core device and an edge device. The edge device identifies a service type of a first service packet from the core device, and reports a service type identifier of the first packet to the core device. The core device determines a priority corresponding to the service type identifier based on a stored service priority correspondence, and forwards, based on the priority, a service packet belonging to a same service flow as the first service packet. A strong service identification capability of the edge device is used to precisely identify thousands of service types, and a strong entry storage capability of the core device is used to store a correspondence that records thousands of service types and priorities. This effectively avoids problems such as transmission congestion and a packet loss that are caused by an incapability of precisely identifying a service type and allocation of a same priority to service packets of different service types.
