Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0030] The embodiment of the present invention provides a software upgrading method, which is suitable for upgrading the software in the master device and the backup device in a stacking system used as a gateway. In practical applications, the stacking system can be deployed in a network as a gateway. For example, the network can be a virtual extensible local area network (English: Virtual eXtensible Local Area Network; VXLAN for short). In the following, the embodiment of the present invention will describe the stacking system A brief description of how to deploy it as a gateway in VXLAN.

[0031] like figure 1 As shown, the VXLAN may have a two-layer fat tree structure, and the fat tree structure includes an access layer, also...

Abstract

The invention discloses a software upgrading method and device and belongs to the technical field of communication. According to the method, before software in a master device and a slave device of astack system which serves as a gateway is upgraded, the stack system is split; the master device and the slave device of the split stack system are connected with neighbor devices of the stack systembased on different logic interfaces, so the master device and the slave device can forward communication data of a server to the neighbor devices; the communication between the server and other serverin a software upgrading process is guaranteed to be not interrupted; the software in the master device and the slave device is upgraded; after the upgrading is finished, a stack link between the master device and the slave device is reestablished; and the master device and the slave device are recombined into the stack system. According to the software upgrading method provided by the invention,the software upgrading stability of the stacking system can be guaranteed.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a software upgrading method and device. Background technique [0002] Currently, the stacking technology has become a very common network device virtualization technology. Using the stacking technology, two physical devices, that is, the primary device and the standby device, can be connected through stacking links to form a stacking system. A stack system can be regarded as a single logical device on the network. In practical applications, the above stacking system can be deployed in the network as a gateway. In this case, the master device and backup device of the stacking system can be connected to a server through their respective access ports, and the A logical interface, such as a local loopback interface (English: loopback), is connected to a neighbor device of the stacking system, and the neighbor device refers to a device establishing a neighbor rel...
