Message forwarding method and message forwarding equipment

Abstract

The application provides a message forwarding method and a piece of message forwarding equipment. The method comprises the following steps: stacking control slots and stacking port extension slots are selected from a stacking system, wherein the stacking control slots are used as a switching and forwarding center of the stacking system and are stacked in an annular or chain mode, and the stacking port extension slots are the remaining slots in the stacking system except the stacking control slots; any of the stacking control slots locally creates cross-equipment aggregation group ports connected with the stacking port extension slots, wherein slot ports of the cross-equipment aggregation group ports are downlink secondary stacking ports, connected with the stacking port extension slots, on the stacking control slots in the stacking system, and the downlink secondary stacking ports are stacking ports, connected with the stacking port extension slots, on the stacking control slots; and any of the stacking control slots selects one slot port from the cross-equipment aggregation group ports connected with the stacking port extension slots to forward a message when forwarding the message to the stacking port extension slots.

Description

technical field [0001] The present application relates to network communication technology, in particular to a message forwarding method and device. Background technique [0002] Stacking means that more than one switching device is combined to work together to provide as many ports as possible in a limited space. Multiple switching devices that support stacking are interconnected to form a combined device. The combined device is called a Stacking (stack), and each switching device that forms the Stacking is called a Slot (member). After multiple Slots form Stacking, both in terms of management and use, it becomes a whole, that is to say, the multiple Slots can be managed and used as a single device, so that expansion can be achieved by adding devices The number of ports and switching capabilities, meanwhile, also increase the reliability of the entire Stacking through mutual backup between multiple Slots. [0003] see figure 1 , figure 1 It is a schematic diagram of exi...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the external stack ports configured by each Slot can be composed of at least one member port, wherein, the member ports of the same external stack port are provided by the same chip, and the member ports of different external stack ports are provided by different chips. The link connection between two adjacent different slots is restricted to be 1:1. In this way, all the traffic between two adjacent different slots will be concentrated on the same link, increasing the link load. Unable to achieve link sharing
