Problems solved by technology

When the total bandwidth of all line cards remains unchanged, if the user replaces the line card in slot 1 with a line card with a bandwidth of 200M, and replaces the line card in slot 2 with a line card with a bandwidth of 1800M , if the backplane bandwidth allocated by the forwarding board to the line card slot before is still used, the backplane bandwidth allocated by the forwarding board to the line card in slot 1 will be redundant, and the backplane bandwidth allocated by the forwarding board to the line card in slot 2 Insufficient bandwidth, resulting in low bandwidth utilization of the forwarding board

Abstract

The present invention proposes a channel multiplexing method for forwarding boards. The method includes: monitoring the slot where the online line card is located, obtaining the bandwidth level of the online line card; counting all line card slots to obtain a statistics including the slot and the corresponding bandwidth level information; optimize and multiplex all or part of the channel bandwidth of the forwarding board according to the statistical information; the present invention also proposes a channel multiplexing device for the forwarding board. The invention improves the bandwidth utilization rate of the forwarding board.

Description

technical field [0001] The invention belongs to the technical field of communications, and in particular relates to a channel multiplexing method and device for a forwarding board. Background technique [0002] Large-scale routing and switching equipment adopts a rack structure, and the rack is equipped with forwarding boards, line cards, switching cards, main control cards, power modules, and fan modules. Line cards are used to provide communication service interfaces, and forwarding boards are used to provide backplane bandwidth support for line cards. Line cards support hot swapping, and different types of line cards provide different service bandwidths. Therefore, forwarding boards are required for The allocated forwarding bandwidth is also different. [0003] At present, when routing and switching equipment leaves the factory, the manufacturer will set a fixed backplane bandwidth value for each line card slot by the forwarding board according to the type of line cards ...
