Embodiment 1

[0036] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown,

[0037] A software-defined network switching device based on the Loongson architecture, such as figure 1 As shown, it includes a control processor unit (composed of two Loongson processors and external devices), the control processor unit is connected with a North Bridge chip using an HT bus, and the North Bridge chip is configured with at least 3 x4 PCIe ports, each of which is connected to There are Ethernet network cards, and each Ethernet network card is equipped with at least 2 Ethernet interfaces. The Ethernet interface is connected to the CPCI port and RJ45 port. The north bridge chip also integrates a display controller and supports multiple interfaces such as VGA and LVDS; the north bridge chip passes The A-Link bus is connected with the South Bridge chip, the South Bridge chip is connected with the CPCI port through the PCI bus, and the South Bridge chip is connected with the carrier hard disk. The ca...

Embodiment 2

[0051] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a data exchange method of a software-defined network switching device based on the Loongson architecture includes the following steps:

[0052] a). The system is powered on, the network switching device loads and runs the Linux system, and the switching device is self-checked;

[0053] b). Load the network exchange service;

[0054] c). After setting and selecting information based on the TCP / UDP protocol, target IP address, and port number of any switching node according to its required data format, start the network application of the switching node and send the data to the network switching device;

[0055] d). The data receiving and sending circuit receives the network data from the switching node and buffers it to the hard disk of the carrier board to join the data buffer queue;

[0056] e). After the network data is transferred to the data parser, the data parser parses the network data according to the correspo...

Abstract

The invention discloses a software-defined network switching device and a data switching method based on the Godson architecture, including a control processor part, the control processor part is connected with a north bridge chip by using an HT bus, and the north bridge chip is configured with at least 3 x4 PCIe ports , each x4 PCIe port is connected to an Ethernet network card, each Ethernet network card is provided with at least 2 Ethernet ports, and the Ethernet port is externally connected to a CPCI port and an RJ45 port; the north bridge chip is connected to the south bridge chip through the A-Link bus, and the south bridge chip is connected to the south bridge chip The bridge chip is connected to the CPCI port through the PCI bus, and the south bridge chip is connected to the hard disk on the carrier board. The hard disk on the carrier board is used to install the Linux operating system. The configuration file of the Linux operating system is pre-configured with user-defined data exchange rules.

Description

Technical field [0001] The invention belongs to the technical field of network switching, a software-defined network switching method and device, and particularly relates to a network switching device based on the Loongson architecture. Background technique [0002] In the process of high-speed advancement of domestically-made controllable technologies, network infrastructure equipment is one of the key equipment related to network security. The core processor and supporting system technology have been in the hands of foreign companies. In addition, the existing network switching device usually adopts a fixed network data exchange strategy configured in a specified mode, or completely releases a strategy of free exchange between ports without strategy. Adopt a fixed exchange strategy, usually with limited configurable combinations, and only provide a limited number of ways. However, in actual application scenarios, there are situations such as network port replication and mirror...
