A method, device, storage medium and electronic device for convergence and distribution based on programmable switching chip

Abstract

The present application discloses a method, device, storage medium, and electronic device for aggregation and distribution based on a programmable switching chip. The comparison result determines whether the parameters corresponding to the information to be matched need advanced filtering; when the parameters corresponding to the information to be matched need advanced filtering, obtain preset custom parameters and insert them into the first packet to generate a second packet Send from channel to compute unit. The calculation unit receives and analyzes the second packet, extracts parameters, detects and generates a detection result; judges whether the second packet needs advanced filtering based on the detection result. Therefore, by adopting the embodiment of the present application, the programmable switching chip can make full use of the programmability of the "programmable switching unit", which can effectively release the computing power and memory of the "computing unit", reduce forwarding delay, improve forwarding efficiency and overall machine throughput Rate.

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 device for aggregation and distribution based on a programmable switch chip. Background technique [0002] The mainstream convergence and distribution equipment consists of "switching unit", "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 with multiple interfaces and different rates, and to provide traffic pre-classification—that is, to filter out the traffic of interest from the massive traffic according to the basic information carried in the packets, and to provide packet discarding, forwarding, Basic forwarding operations such as replication and mirroring. [0003] At present, the solutions of traditional aggregation and distribution equipment for processing acces...

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
