Problems solved by technology

[0051] The Module_map table needs to be statically configured, that is, the Module_map table needs to be manually configured. For a more complex multi-chip structure, the configuration workload is relatively large, errors are prone to occur, and it is difficult to change dynamically

Embodiment Construction

[0093]The core idea of ​​the present invention is: carry the chip number of source edge switch and the chip number of purpose edge switch and other relevant information of data packet forwarding in the data packet that each edge switch sends to center switch, for example: data packet type, source port number, destination port number, etc., on the central switch, according to the chip number of the source edge switch, it can be determined whether to update the Module_map, if it is necessary to update the Module_map, it can be based on the chip number of the source edge switch and the input port of the data packet (that is, the port that receives the data packet on the central switch) updates the Module_map; thereby realizing the dynamic update of the Module_map, and then realizing the automatic forwarding process between the switching chips, and reducing a lot of configuration work; and it can be realized without configuration The stacking between multiple switching chips reduce...

Abstract

The invention discloses a data processing method, which comprises the following steps that: a central switch receives a data packet from a source edge switch; the central switch judges whether Module-map needs updating or not according to the chip number of the source edge switch carried in the data packet and an input port of the data packet; the central switch updates the Module-map according to the chip number of the source edge switch carried in the data packet and the input port of the data packet if judging the Module-map needs updating; and the central switch transmits the data packet to a destination edge switch according to the Module-map. In the data processing method, automatic forwarding is realized between switching chips and a large amount of configuration work is reduced; besides, the stacking of a plurality of switching chips can be realized without configuration, so difficulty in development brought by the stacking of the plurality of chips is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data processing method and device. Background technique [0002] In current Ethernet switches, transparent bridging technology is generally used, and the transparent bridging is usually used to connect or expand two or more Ethernet (Ethernet) networks into a single logical LAN (Local Area Network, local area network). [0003] In transparent bridging technology, the bridge only transmits frames one hop each time according to the association table between the end node and the bridge port. The bridge is transparent to the end nodes of the network, that is, the transparent bridge does not need The content of the data frame is changed, and it is not used as the source or destination address of the data frame, so that the various network segments connected by the transparent bridge look like they are on a cable. Among them, transparent bridging generally has five ...
