Embodiment 1
[0040] Such as figure 2 As shown, the embodiment of the present invention provides a device for implementing cross-device data forwarding of a virtual cluster switch, including: a main control board, an active stacking board, and a standby stacking board, wherein:
[0041] The main control board is used to respectively set the forwarding logic with the active stacking board and the standby stacking board, and send the same message data to the active stacking board and the standby stacking board, and when the active stacking board is in In the working state, the main stacking board is set to forward the message data, and when the main stacking board is in the non-working state, the standby stacking board is set to start working;
[0042] Wherein, the main control board is also used to block the data port connected to the standby stack board when the main stack board is in the working state, so that the message data sent to the standby stack board is discarded, so as to In thi...
Embodiment 2
[0063] This embodiment mainly describes the improvement of the existing method for cross-device data forwarding of virtual cluster switches. The workflow of cross-device data forwarding of virtual cluster switches in this embodiment is as follows: Figure 4 shown, including the following steps:
[0064] Steps S401-S403 are the same as steps S101-S103 in the background technology;
[0065] S404: The main control board of device 1 sends the same message data to the active stack board and standby stack board of device 1;
[0066] S405: The main control board of device 1 detects whether there is a response event that the main stack board is in a non-working state, and if the main stack board is in a non-working state, go to step S407; otherwise, go to step S406;
[0067] S406: The active stack board of device 1 forwards the packet data;
[0068] S407: The main control board of device 1 sets the backup stack board of device 1 to start working, and the backup stack board of device...

Abstract
The invention discloses a method for realizing Virtual Switch Cluster (VSC) cross equipment data forwarding and equipment thereof. The method comprises the following steps: a main control board set forwarding logic with a main stack plate and a standby stack plate respectively; the main control board sends a same message data to the main stack plate and the standby stack plate; when the main stack plate is in a working state, the main stack plate forwards the message data; when the main stack plate is not in a working state, the main control board set the standby stack plate to start working, and the standby stack plate forwards the message data. According to the method and the equipment in the invention, Virtual Switch Cluster (VSC) cross equipment data forwarding is realized, reliability of data link among Virtual Switch Clusters is considered, and data forwarding between Virtual Switch Cluster (VSC) cross equipment is recovered in a time scale of milliseconds when a link breakdown happens.
Description
technical field [0001] The invention relates to the field of data communication, in particular to a method and a device for realizing cross-device data forwarding of a virtual cluster switch. Background technique [0002] A virtual switch cluster (Virtual Switch Cluster, VSC for short) system is an application of a network virtualization technology. In the VSC system, multiple physical devices that can run independently are combined into a virtual device. Each physical device discovers each other through the topology discovery protocol, and selects a master device through a certain mechanism, and other devices take the role of forwarding. [0003] In a virtual cluster switch scenario, communication (including data forwarding and control communication) between various physical devices is very important. Currently, if figure 1 As shown, the existing cross-device (such as between device 1 and device 2) data forwarding methods of virtual cluster switches include: [0004] S10...
