Gathering and shunting method and device based on programmable switching chip, storage medium and electronic equipment

Abstract

The invention discloses a convergence and distribution method and device based on a programmable switching chip, a storage medium and electronic equipment. The method comprises the steps: enabling a programmable switching unit to obtain pre-extracted to-be-matched information and compare the pre-extracted to-be-matched information with a preset flow table; judging whether parameters correspondingto the to-be-matched information need to be subjected to advanced filtering or not according to the comparison result; and when the parameter corresponding to the to-be-matched information needs to besubjected to advanced filtering, obtaining a preset custom parameter, inserting the preset custom parameter into the first packet to generate a second packet, and sending the second packet to a computing unit from a channel. The calculation unit receives the second packet, analyzes the second packet, extracts parameters and detects the parameters to generate a detection result; and judging whether the second packet needs to be subjected to advanced filtering or not based on a detection result. Therefore, by adopting the embodiment of the invention, the programmable switching chip fully utilizes the programmability of the programmable switching unit, the computing power and the memory of the computing unit can be effectively released, the forwarding time delay is reduced, and the forwarding efficiency and the complete machine throughput rate are improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device, storage medium and electronic equipment for converging and distributing traffic based on a programmable switching chip. Background technique [0002] The mainstream aggregation and distribution equipment consists of a "switching unit", a "computing unit" and a data channel with a certain bandwidth capability between the "switching unit" and the "computing unit". The purpose of the "switching unit" is to provide access capabilities of multiple interfaces and different rates, and at the same time provide traffic pre-classification—that is, from the massive traffic, filter out the traffic of interest based on the basic information carried in the packet, and provide packet discarding, forwarding, Basic forwarding operations such as replication and mirroring. [0003] At present, the traditional aggregation and distribution equipment for processing i...

Problems solved by technology

However, due to the non-programmable "switching unit" scheme, the processing status of the packet on the "switching unit" cannot be synchronized to the "computing unit"

This introduces the following problems: 1) The calculation unit must deploy the same type of pre-classification (pre-filtering) rules for the basic information of the packet to determine whether it is necessary to perform advanced filtering and / or advanced processing on the current packet to cause consumption 2) At the same time, the "computing unit" needs to perform matching of basic traffic, which consumes computing power; 3) Multiple search results need to be processed separately (the priority should be determined when multiple matching results are used), and the forwarding path is too long, resulting in the entire path The forwarding delay increases
