[0048] Such as figure 1 It is shown in the schematic diagram of the CPU architecture of the network equipment of the present invention: a network equipment / wireless local network equipment (AP), including a CPU,

[0049] The CPU is a multi-core CPU;

[0050] The multi-core CPU includes at least one basic core and at least one data task core;

[0051] The basic core (core0) is used to manage and control the network device, and / or control the data task core;

[0052] The data task cores (take a quad-core CPU as an example, Core1-core3) are used to process corresponding data streams passing through the network device.

[0053] In this AP device, a multi-core CPU is used as the core of the device. Taking a quad-core CPU as an example, we can run openwrt on the basic core0 to manage and control the entire device, while the rest of the data task core1~core3 can run independent work processes dedicated to various data acceleration.

[0054] Such as figure 1 As shown, OpenWRT run...

[0065] Preferably, in the method for managing and controlling data flow in the network, under the management of the basic core (core0), a plurality of the data task cores cooperate with each other to complete the work process. Such as image 3 It is shown in the working diagram of the second embodiment of the present invention: taking a quad-core CPU as an example, the data task cores (core1-core3) can create different work processes according to the requirements, and bind the work processes to a certain core, and the different Functional processes are connected in series to form a pipeline to implement one or more features.

no. 3 example

[0067] For data task cores in multi-core CPUs, the working process can focus on a single function. Under the management of the basic core (core0), the data task core (core1 / core2 / core3) can run multiple working processes at the same time: for example, the Tx process focusing on sending and receiving, the Rx process, and the classification process of data classification , the encryption process of data encryption, etc. Or several combined functions, such as Rx (receive data from IO port), then modify data (add VLANtag), Tx (send from another IO port), such as Figure 4 It is shown in the working schematic diagram of the third embodiment of the present invention.

Abstract

The invention relates to the technical field of networks / the technical field of wireless local area networks, and particularly relates to data acceleration technology and data detection technology on a WIFI network. The invention discloses a network device comprising a CPU, wherein the CPU is a multi-core CPU; the multi-core CPU comprises at least one basic core and at least one data task core; the basic core is used for managing and controlling the network device, managing and controlling the data task core and creating, managing or deleting a working process running in the data task core; and the data task core is used for running the working process in the data task core to process data flow corresponding to the network device. By means of the multi-core, acceleration processing is carried out on AP data to realize functions that cannot be realized by general AP, and thus the user experience is improved.

Description

technical field [0001] The present application relates to the field of network technology / the field of wireless local area network technology, and in particular to data acceleration technology and data detection technology on WIFI networks. Background technique [0002] A WLAN is mainly composed of a station (Station, STA), an access point (Access Point, AP), a wireless medium (WirelessMedium, WM) and a distributed system (Dis-tribution System, DS). [0003] station (STA). The STA is generally a client in a WLAN, which can be a computer equipped with a wireless network card or a smart phone with a WiFi module. STA can be mobile or fixed, and is the most basic unit of WLAN. [0004] In the AP (access point), the introduction of protocols such as 802.11AC has greatly increased the number of user accesses and access bandwidth, and improved the user's online experience. In the wireless environment, there are more and more data streams related to QoS, such as IP telephony, vid...
