DETAILED DESCRIPTION

In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided below in conjunction with the drawings is not intended to limit the scope of protection of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application. The utility model is further described below in conjunction with the drawings.

The utility model specifically relates to a 6U VPX 10G network processing card based on a domestic processor, which utilizes the flexible scalability and high reusability of highly integrated modules, adopts a PCIe+network card+PCIe Swicth design, and can realize the required interface through PCIe. It is more convenient to upgrade, replace and maintain the entire product, and its flexibility, maintainability and life cycle are all higher than other types of products.

As shown in Figure 1, it includes a domestic processor unit, a BMC unit, a PCIe Switch chip, a 10 Gigabit network card chip, a Gigabit network card chip, a storage unit and an interface unit; the domestic processor unit is connected to the interface unit, connected to the storage unit through a SATA serial port, connected to the BMC unit through a UART serial port, connected to the Gigabit network card chip and the PCIe Switch chip through a PCIE serial port, and the PCIe Switch chip is connected to the 10 Gigabit network card chip through a PCIE serial port; the PCIe Switch chip, the 10 Gigabit network card chip, the Gigabit network card chip and the BMC unit are connected to the VPX backplane; the domestic processor unit is connected to the VPX backplane through USB and DVI interfaces.

Furthermore, the interface unit includes a LAN interface, a USB interface, a GPIO interface, a debugging serial port and a level conversion unit; the LAN interface, USB interface, GPIO interface and VGA interface are connected to the domestic processing unit, and the debugging serial port is connected to the domestic processor unit through the level conversion unit.

Among them, the interface unit also includes a VGA interface, a VGA switching switch and a DP to VGA unit; the VGA port of the domestic processor unit is connected to the VGA switching switch, the DP port of the domestic processor unit is connected to the VGA switching switch through the DP to VGA unit, and the VGA switching switch is connected to the VGA interface.

Furthermore, if the utility model does not install a domestic processor unit, the PCIe signal provided by the VPX backplane is accessed through the PCIe Switch chip. At this time, the board is used as a 10G network card expansion card to achieve 10G-KR and 1G Serdes interface expansion.

Among them, the domestic processor units include the Loongson 3A5000 or Loongson Feiteng D2000 domestic processors. When installing any domestic processor, the PCIe bus of the 10G network card and the 1G network card is connected to the processor module unit, which serves as the core control board and the processor's 10G network port sends and receives related data.

As shown in Figure 2, if after installing the Loongson 3A5000 domestic processor module unit, the 6U VPX network processing board can be used as a computing node Host1. Through the PCIe Switch chip and the NTB non-transparent bridge, computing nodes Host2 of other different processor platforms (such as Feiteng D2000 computer nodes) can be added to collaboratively process the relevant data sent and received by the 10 Gigabit network port to improve computing efficiency.

The two computing nodes Host are interconnected with the PCIe Switch through the NTB non-transparent bridge, so that each computing node can access each other in pairs. The characteristics of different computer nodes, such as security mechanisms and computing capabilities, are fully utilized to improve the performance of the entire system.

The meanings of the English abbreviations involved in this utility model are as follows:

VPX: It is a new generation of high-speed serial bus standard proposed by VITA (VME International Trade Association) in 2007 based on its VME bus. The basic specifications, mechanical structure and bus signals of VPX bus are defined in the ANSI/VITA46 series of technical specifications.

PCIe Switch: PCIe is a high-speed serial computer expansion bus standard. Its supporting Switch chip is similar to a network switch and is used to exchange data between high-speed serial buses.

NTB: Non-Transparent Bridging, which allows one SoC system to directly access the memory and peripherals of another SoC system. Usually, this requires a switch system to transfer, but NTB switches allow direct access, which is particularly suitable for the interconnection between two different chips or chiplets. Sometimes, when a SoC system does not have enough memory, it can directly call the memory of another SoC system, and multiple chips are operating as if they were one chip.

EP: The full English name is Endpoint, which means terminal equipment and does not have the function of forwarding data.

The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used for various other combinations, modifications and improvements, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge in the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
