Problems solved by technology

[0008] It can be seen that in the current business packet forwarding scheme, when a large number of new business flows arrive, the forwarding performance of subsequent packets is greatly reduced, resulting in the instability of the overall packet forwarding performance

Embodiment Construction

[0048] The embodiment of the present invention provides a business packet processing method applied to the occasion with multi-processing engines. The basic idea is: first add a new flow queue, and buffer the service packets to be forwarded in the message queue called the follow-up flow queue Medium; according to the set scheduling ratio, the pending service packets in the follow-up flow queue and the new flow queue are scheduled to the processing engine, and the scheduling ratio is greater than 1; When the session table is hit, the pending service packet is cached in the newly created flow queue, waiting for re-scheduling; when it is determined that the pending service packet from the subsequent flow queue hits the session table, the subsequent processing operation is performed according to the hit session table ; Perform follow-up processing operations on the service packets to be processed in the newly created flow queue.

[0049] Among them, which processing engine to sche...

Abstract

The invention discloses a service processing method. The method caches the to-be transferred service to the subsequence stream array; scheduling the to-be processed service message in the subsequence stream array and the predetermined new-built stream array to the processing engine according to the proportion of the predetermined scheduling number; the scheduling number proportion is more than 1; while the processing engine judges the to-be processed service message in the subsequence stream array never targets the conversation table, caching the to-be transferred service to the new-built stream array; while judging the to-be processed service message in the subsequence stream array never targets the conversation table, implementing the subsequence processing operation according to the targeted conversation table; the processing engine implements the subsequence processing operation for the to-be transferred service message in the new-built stream array. The embodiment of the invention also discloses a service processing device. The invention can enhance the transferring functions for the subsequence package while a large amount service streams is coming.

Description

technical field [0001] The invention relates to message processing technology, in particular to a service message processing method and a service message processing device applied to concurrent processing of service messages by multi-processing engines. Background technique [0002] In the process of message forwarding, the business processing of business messages consumes a large amount of execution resources. In order to improve the processing capacity of business data, multi-core CPU technology or network processors (NP, Network Processor) with multi-stage pipelines are usually used at present. Technology realizes the business processing and forwarding of business messages, whether it is a multi-core CPU or NP is a concurrent processing technology based on multiple processing engines. In multi-core CPU technology, each processing engine completes four stages of processing: element extraction of service messages, session table lookup, session table lookup result processing...
