Description

Technical Field

[0001] The invention belongs to the technical field of embedded computer system design, and in particular relates to a storage architecture for data transmission processing under multiple network ports. Background Art

[0002] With the development of modern information technology, the integration of airborne electronic computer equipment is constantly improving, the amount of airborne data is constantly increasing, the number of transmission devices is constantly increasing, and the transmission rate requirements are constantly increasing. Therefore, to realize the communication and data filtering functions of network security software, it is necessary to design a multi-network port airborne data exchange storage architecture to meet the current data transmission requirements of airborne electronic equipment.

[0003] Due to the continuous increase in the amount of airborne data transmission, the continuous improvement of data transmission bandwidth and transmission rate requirements, and the need for more and more airborne devices to communicate, transmit and store data with each other, the traditional low-speed data transmission architecture cannot meet the requirements (such as using a daisy chain architecture to carry out half-duplex or full-duplex low-speed transmission mode). Networking multiple network nodes to achieve multi-channel 100M or Gigabit data transmission has become the future development trend of data transmission. Seeking a method for multi-channel Gigabit Ethernet to network equipment to achieve data transmission, processing and storage has become an imperative trend. Traditional solutions often use electrical signals such as R422 and R485 for communication and data transmission, but the transmission distance is insufficient, the bandwidth is small, and the transmission rate is slow. Later, in order to increase the transmission speed, PCIE was used for data transmission, but the cost of PCIE is too high and the management is complicated, which is not suitable for most devices. In order to meet the above requirements, it is necessary to design a high-speed communication storage switching architecture that is suitable for multi-device connection, easy to deploy, and low-cost.

[0037] Wherein: each unit on the storage architecture supports the Linux operating system, and supports the selection of multiple network modes by setting the network mode through relevant network configuration.

[0038] In this embodiment, the processor unit implements network security software communication and data filtering functions based on the control of the CPU, performs data processing, screening, forwarding and storage, and is used to implement external interrupts and reset signal processing.

[0041] In this embodiment, the FLASH is used to store the BOOT boot program, operating system, application software and configuration parameters.

[0042] In this embodiment, the storage unit of the storage circuit is an SSD, and the SSD is used to store compressed data.

[0043] In this embodiment, the CPU of the processor circuit receives and filters the data transmitted by the multiple devices connected to the multi-channel network port circuit, and then stores the data;

[0044] The processing unit of the processor circuit has a built-in cryptographic acceleration engine and an integrated system-level security mechanism; the CPU is externally mounted with a related storage configuration circuit, which is used to store the CPU's BOOT boot program, operating system, application software and configuration parameters.

[0046] In this embodiment, the CPU is connected to the SSD via PCIE 3.0, the transmission rate is not less than 1800MB / s, and the storage capacity of the SSD is not less than 4TB.

[0047] The architecture of this embodiment realizes parallel communication of up to 12 network ports for data transmission, and its rate can reach up to 1Gbps. It can be backward compatible with various transmission rates through flexible configuration, supports adaptive settings, and realizes the function of data transmission and processing of multiple devices at the same time. The system includes four parts: a processor unit, a multi-network port unit, a storage unit, and a programmable unit, and supports the operation of related operating systems such as Linux, among which:

[0048] The processor unit receives and filters the data transmitted by multiple devices, and then saves the data. In the processing unit, there is a built-in cryptographic acceleration engine and an integrated system-level security mechanism, which can meet the performance requirements and security and trust requirements in complex application scenarios. The processor unit is externally connected to the relevant storage configuration circuit to store the BOOT boot program, operating system, application software and configuration parameters of the processor unit. The processor unit is at the core of the entire network switching storage architecture, and is connected to the multi-port unit and storage unit through PCIE to realize the overall data processing and transfer functions.

[0049] The multi-port unit supports up to 12 Ethernet channels at 1Gbps for multi-channel parallel communication and data transmission. In the Linux operating system environment, it can support auto-negotiation of transmission rates of 1000M and below, and also supports bridge mode, which can realize mutual communication between multiple mounted devices in the same network segment. Or by configuring the network Bonding mode, it can achieve load balancing of traffic on each network port, provide redundant backup, improve network performance, and adapt to various network scenario requirements.

[0050] Due to the increase in the number of input channels and the improvement in transmission speed, the amount of data processed has increased linearly. In order to improve the transmission efficiency and recording capacity of the processed data, it is connected to the storage unit (SSD) through PCIE 3.0, with a transmission rate of up to 1800MB / s and a storage capacity of up to 4TB.

[0051] The programmable unit module provides power-on timing control for the entire architecture, powers on the required operating voltage of each module according to the timing, and resets each model of the entire architecture by receiving external or internal reset instructions.

[0052] The processor unit processes and filters multiple data inputs to realize network security software communication and data filtering functions. Its speed can reach up to 1Gbps and can support up to 12 network ports to communicate and access each other simultaneously.

[0053] The multi-network port unit sets the mounted device according to the relevant network mode, and can perform data transmission and communication in the same network segment or different network segments.

[0059] like Figure 1 As shown, the programmable logic unit of this embodiment is responsible for the power-on timing control of the entire board to ensure the normal startup of the remaining units of the entire board. At the same time, by receiving external or internal reset signals, the remaining units of the entire board are reset to ensure the normal operation of all units.

[0060] The multi-network port unit is responsible for mounting external devices. By setting relevant configurations, the external devices are placed in the same or different IP segments, so that the mounted peripherals can communicate and transmit data through the processor unit. At the same time, different network modes can be configured according to actual usage to achieve redundant backup or load balancing functions. The multi-network port unit will hand over the received data to the processor for processing and screening.

[0061] The processor unit is the core control and processing unit of the entire architecture, which is used to receive, process and filter data transmitted by multiple network ports. In this processing unit, there is a built-in cryptographic acceleration engine and an integrated system-level security mechanism, which can meet the performance requirements and security and trust requirements in complex application scenarios. Finally, the processed and filtered data is stored in disk according to the instructions.

[0062] The recording unit is the last step of the device, which is an NVME solid-state storage hard disk connected to the processor unit through a PCIE bus. In TLC mode, the storage capacity can reach 4TB, and the read and write rate can reach 1800MB / s. It has the advantages of large capacity, small size, low power consumption and high performance. At the same time, data can be quickly unloaded through a USB device to meet the quick unloading needs.
