Embodiment Construction

[0022] The core idea of ​​the present invention is: in a system that includes a distribution module and multiple forwarding modules, and the distribution module distributes the received large messages to each forwarding module for processing with a certain load sharing strategy, between the distribution module and the forwarding module Introduce another entity, that is, the data flow object; the distribution module no longer writes the message directly into the queue of the forwarding module, but writes it into the queue of the data flow object; each forwarding module dynamically selects each data flow object and processes it packets in its queue. Usually, a data stream object corresponds to a queue.

[0023] In order to make the object, technical solution and advantages of the present invention clearer, in the following examples, as figure 1 The shown multi-core system is an application scenario, and describes the solution of the present invention. That is, in the following...

Abstract

The invention discloses a message forwarding method and a device. The method comprises the following steps: a plurality of data flow objects are built in a system comprising a distributing module and a plurality of forwarding modules, a corresponding relation between a hash value and the data flow object is built; after receiving the message, the distributing module carries out hash operation to obtain the hash value according to the content in a specified field of the message, and the message is written into an array of a data flow object corresponding to the hash value; an idle forwarding module obtains an unattended processing data flow object, and then, the message is obtained from the array of the data flow object to forward; the unattended processing data flow object refers to a data flow object which has no forwarding module to process messages in the array. The technical scheme of the invention ensures that the message forwarding in a multi-core system is more balanced, and the forwarding ability of the multi-core system is improved.

Description

technical field [0001] The invention relates to the technical field of multi-core systems, in particular to a message forwarding method and device. Background technique [0002] With the slowdown of central processing unit (CPU) frequency increase, multi-core technology has emerged to improve processing performance. At present, more and more network devices are equipped with multi-core CPUs to improve software performance. For example, a multi-core router device improves data forwarding performance by increasing the number of cores. [0003] After the message enters the multi-core system, it usually needs to be distributed first, and the messages of different service flows are distributed to different cores for processing, so as to make full use of each core of the CPU. [0004] figure 1 It is a schematic diagram of packet distribution in an existing multi-core system. Such as figure 1 As shown, the multi-core system includes a distribution core and multiple forwarding ...
