Problems solved by technology

This bypass packet capture mode can only improve the receiving performance of network protocol packets in the laboratory environment, but it cannot solve the problem of parallelism in the sending direction of packets.
Therefore, this model has limited performance improvement and cannot be applied in a professional system environment with limited resources such as embedded
Moreover, this parallel method adopts a random scheduling model, which cannot perform dynamic intervention, load balancing, and custom policy scheduling according to the user's actual network pressure, traffic, and complex application scenarios

Abstract

The invention provides a parallel processing frame for improving performance of 10-gigabit Ethernet. The frame comprises a message distribution layer, a message policy classifier, a network protocol processing layer, and an application interface layer, wherein the message distribution layer is configured to process message reception and transmission, and realize parallel processing of a network card interrupt level; the message policy classifier is configured to formulate a distribution policy, and match the classification result of messages obtained by a classification algorithm through the distribution policy with a network protocol stack instance of the network protocol processing layer; the network protocol processing layer is configured to establish an independent resource pool for the network protocol stack instance based on the parallelization of sharpening the user space network protocol stack of the embedded operating system, wherein the resource pool is associated with the processor core running by the network protocol stack instance, and a multi-core operation processing interface is used to process the message; and the application interface layer is configured for the interaction between the network application and the network protocol stack of the network protocol processing layer, thereby realizing that the message sent by the network application is offloaded to the network protocol stack instance of the network protocol processing layer for processing.

Description

technical field [0001] The present invention relates to the technical field of parallel processing, in particular, to a parallel processing framework for improving the performance of 10 Gigabit Ethernet, especially to a multi-core hardware platform based on the Ruihua embedded domestic operating system using multi-core processing SMP (Symmetrical Multi-Processing) framework and parallel computing capacity model, using user-mode, configurable, multi-instance parallel protocol stack architecture, integrated support for user-defined message classification, scheduling policy mechanism to improve the parallelism of 10 Gigabit Ethernet performance chemical treatment technology.
