Embodiment Construction

[0033] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a method for transmitting service packets. The method is applied to a VCF network including CB devices and PE devices. The multiple CB devices form an IRF, and each Each PE device is connected to one or more CB devices, but not all PE devices in the VCF network are connected to all CB devices.

[0034] by image 3 It is a schematic diagram of the application scenario of the embodiment of the present invention. The CB devices in the VCF network include CB_1, CB_2, CB_3, and CB_4, and CB_1, CB_2, CB_3, and CB_4 form an IRF; the PE devices in the VCF network include PE100, PE101, and PE102 ; In addition, PE100 is connected to internal and external server 1, PE102 is connected to internal and external server 2, and CB_3 can be connected to external network devices.

[0035] In the above application scenarios, such as Figure 4 As shown, the transmission method of the service...

Abstract

The invention discloses a method and equipment for transmitting service messages. The method includes: when a PE device receives a first unicast service message from a CB device, it uses the source MAC address of the first unicast service message to query MAC forwarding table; if the source MAC address is not recorded in the MAC forwarding table, the PE device records the correspondence between the source MAC address and the receiving port of the first unicast service message in the MAC forwarding table; When receiving the second unicast service message from the intranet server, use the destination MAC address of the second unicast service message to query the MAC forwarding table; if the destination MAC address is recorded in the MAC forwarding table, use the MAC forwarding table The egress port corresponding to the destination MAC address recorded in , sends the second unicast service packet to the CB device. In the embodiment of the present invention, the PE device can transmit the unicast service message based on the shortest path, and improve the forwarding efficiency of the unicast service message.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and equipment for transmitting service messages. Background technique [0002] VCF (Vertical Converged Framework) is a new generation of network device virtualization technology. VCF supports heterogeneous expansion of the system in the vertical dimension, that is, on the basis of forming a logical virtual device, a box device is added to the main device system as a remote interface board to achieve extended I / O (input / output) port capability and the purpose of centralized control management. [0003] For a VCF network, devices are divided into CB (Controlling Bridge, control bridge) devices and PE (Port Extender, port extension) devices according to their roles. Such as figure 1 As shown in the figure, it is a schematic diagram of the VCF network. The CB device is the control device, and the PE device is the vertical expansion device, that is, the por...
