Problems solved by technology

However, in the case of constantly changing network service traffic, the strategy of randomly or statically binding service flows to multiple processing cores cannot balance the load of multiple processing cores in real time, and cannot efficiently use multiple processing cores to process network services

Embodiment Construction

[0021] figure 1 is a schematic diagram of the network service flow processing device of the present invention.

[0022] Such as figure 1 As shown, the device includes a data packet capture module 100, a service flow matching module 120, a dynamic allocation module 140, a service flow allocation list 180, and service flow processing modules 160-1, 160-2, 160-3...160-n , wherein the dynamic allocation module 140 includes a service flow activity level determination module 140-1, a CPU load acquisition module 140-2, and a service flow allocation module 140-3.

[0023] The data packet capture module 100 captures data packets from network links and sends them to the traffic flow matching module 120 . Preferably, the data packet capture module is an Ethernet network card, a DAG card or the like.

[0024] The service flow matching module 120 matches the captured data packets into service flows. The data packet is the basic unit of data transmission in the network, and the business...

Abstract

The invention relates to a method and a device for the multi-core parallel concurrent processing of network traffic flows. The method comprises the following steps: capturing a data pocket from a network; and unpacking the data pocket into a plurality of traffic flows and generating a traffic flow distribution list so that a multi-core processor processes the traffic flows according to the traffic flow distribution list. The method is characterized by also comprising following steps: acquiring the load condition of each processing core; and confirming the active level of each traffic flow after generating the traffic flow distribution list which is changed according to the load conditions and the active levels so as to dynamically distribute the traffic flows. The invention effectively adjusts the load of each processing core and fully utilizes the processing performance of the multi-core processor by dynamically distributing the network traffic flows into a plurality of processing cores.

Description

technical field [0001] The invention relates to a multi-core parallel network service flow processing method and equipment. Background technique [0002] With the continuous development of the Internet, the previous network processing mechanism has been unable to adapt to the development of the network. At the same time, with the rapid development of hardware technology, multi-core processing technology has emerged. Multiple processing cores share cache, storage space, bus and other resources, making it possible for multiple processing cores to perform parallel computing; it also provides a new solution for improving network packet processing performance. [0003] In the past, the processing of network service flow was performed by one processing core in the multi-core processor, and the load of each processing core could not be effectively adjusted to achieve hardware usage balance and fully utilize hardware resources. Recently, techniques have emerged for distributing ne...
