Message forwarding method and device

Abstract

This application provides a message forwarding method and device. Wherein, the method includes: selecting a stacking control member and a stacking port expansion member from the stacking system, wherein the stacking control member serves as the switching and forwarding center of the stacking system, and stacks each other through a ring or a chain, and the stacking port expansion member For the remaining members in the stack system except the stack control member; any stack control member locally creates a cross-device aggregation group port connected to the stack port expansion member, and the member port of the cross-device aggregation group port is the stack system Each stack control member is connected to the downlink secondary stack port of the stack port expansion member, and the downlink secondary stack port is the stack port connected to the stack port expansion member on the stack control member; any stack control member is connected to the stack port When the extended member forwards the message, a member port is selected from the inter-device aggregation group ports connected to the extended member of the stack port to forward the message.

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...

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
