Embodiment Construction

[0047] Generally, there are mainly two methods in the process of packet processing. One method is that the scheduler before version 2.6 of linux adopts a priority-based design to process packets. Specifically: in a multi-core system, only one run queue is saved to process messages, and each CPU compares the priorities of all processes in the run queue in turn, and selects the process with the highest priority as the next scheduled process. After the linux2.6 version, more scheduler algorithms have been added. But the goals of the thanks scheduler and the fast-forward virtual thread scheduler are different. The linux scheduler is oriented to the operating system, and needs to consider the interactive response and batch processing capabilities of the system at the same time. In the field of message forwarding, virtual thread scheduling considers the allocation of message processing stages and the message forwarding capability. Another way is to process packets based on a prior...

Abstract

The invention discloses a message processing method and a message processing device. The method comprises the following steps of dividing multi-core central processing unit CPU of a processed message into at least one scheduling domain, and dividing a virtual thread of the processed message into at least one virtual thread working group; respectively distributing the at least one scheduling domain for the at least one virtual thread working group; according to the at least one distributed scheduling domain, and according to the load balancing principle, processing messages in each virtual thread working group. The message processing method and the message processing device are used for solving the problems that CPU resources are wasted comparatively, and the message processing flexibility is lower by an adopted priority global scheduling algorithm under the normal conditions when message processing is performed.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a message processing method and device. Background technique [0002] IP network devices, such as switches, routers, firewalls, and gateways, are used as data exchange nodes for computer interconnection, and their data forwarding performance determines the overall quality of the network. With the rapid increase in the number of user connections and the emergence of various high-bandwidth applications, it is increasingly difficult for single-core processors with limited main frequency to meet the performance requirements of high-speed data forwarding. Capability and parallel computing characteristics, gradually widely used in the field of network communication. The so-called multi-core processor refers to the integration of multiple core processors (English: Core-CPU) on a hardware chip, usually in a shared memory structure. The multi-core processor has relatively inde...
