Embodiment Construction

[0065] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0066] Please refer to figure 2 , which shows a schematic flowchart of a device switching method provided by an embodiment of the present invention. The device switching method can be applied to the first routing bridge device in the multi-homing access group, and the first routing bridge device is preset as an alternative designated forwarding device of the user virtual local area network in the TRILL network, and the device switching method can include :

[0067] Step 102, detecting whether the second routing bridge device in the multi-homing access group fails, and the second routing bridge device is the designated forwarding device of the user virtual local area network;

[0068] Step 104, if the detection result is that the sec...

Abstract

The invention discloses an equipment switching method and routing bridge equipment and system, and belongs to the field of data exchange. The equipment switching method comprises the steps that detecting whether a failure exists in second routing bridge equipment of multiple access groups or not is conducted, and the second routing bridge equipment is appointed transmit equipment of a user virtual local area network; if a detected result is that the failure exists in the second routing bridge equipment, first routing bridge equipment is switched to be the appointed transmit equipment of the user virtual local area network. According to the equipment switching method and the routing bridge equipment and system, when the failure is detected in the appointed transmit equipment of the user virtual local area network, the first routing bridge equipment which is preset to be alternative appointed transmit equipment is switched to be the appointed transmit equipment of the user virtual local area network, the problem that in the prior art, data flow is interrupted due to the fact that after a reappointed AF waits for a period, the AF starts to transmit corresponding data of the CE VLAN is solved, and the aim of improving the transmission performance of the system is achieved.

Description

technical field [0001] The invention relates to the field of data exchange, in particular to a device switching method, routing bridge device and system. Background technique [0002] Transparent Interconnection of Lots of Links (English: Transparent Interconnection of Lots of Links, abbreviation: TRILL) protocol is a protocol based on link state calculation on a Layer 2 forwarding network. A TRILL network includes several routing bridge devices (English: Router Bridge, abbreviation: RB), and each RB can be connected to peripheral devices. When data exchange is required between different customer edge devices (English: customer edge, CE) connected to two RBs in the same TRILL network, the source CE sends the data to the RB connected to it, and the source CE sends the data to the RB connected to the source CE. The RB in the TRILL network calculates the forwarding path in the TRILL network, and forwards the data to the RB connected to the destination CE according to the calcu...
