Data interaction method and device in a stacking system

Abstract

The invention discloses a data interactive method in a stack system. The method comprises the following steps: a stack member equipment acquires the state of a main control board of the opposite end member equipment; whether the main control board of the opposite end member equipment can be used or not is judged according to the state of the main control board; when the judging result is 'yes', the stack member equipment and the opposite end member equipment interact data flow and control flow; and when the judging result is 'no', the stack member equipment and the opposite end member equipment interact data flow. The invention guarantees continuous transmission of data and improves the reliability and availability of the member equipment.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data interaction method and device in a stacking system. Background technique [0002] With the rapid increase of network scale, stacking technology emerges as the times require. Among them, the stacking technology is to connect two or more network devices through stacking ports to form a stacking system. Logically speaking, the network devices formed by stacking together are equivalent to the same device, and the user manages the stack system just like managing one device, that is, the user can manage all the devices in the stack by managing the stack system. Among them, the stacking technology can provide high availability, high scalability, and simplify management, and has been widely used in data centers and enterprise core networks. [0003] In the prior art, stacking technologies applied in data centers mainly include IRF (Intelligent Resilient Framewor...

Problems solved by technology

[0006] In the existing stacking technology, if there is only one main control board in the frame-type device, when the main control board fails, the traffic passing through the frame-type device will be interrupted, resulting in the unavailability of the frame-type device

like figure 2 As shown, for the case where two main control boards are supported in a frame-type device, for device 1 (the main frame), when all the main control boards in device 1 are damaged (that is, both the master and slave1 of the main control board are damaged), the method The traffic of device 1 will be interrupted, making device 1 unusable

Similarly, when all the main control boards of device 2 are damaged, the traffic passing through device 2 will also be interrupted, making device 2 unusable

[0007] However, in application scenarios such as data centers and enterprise core networks, higher and higher requirements are put forward for the availability and uninterrupted forwarding of the stacking system; The interruption of business forwarding cannot meet the business requirements of uninterrupted forwarding
