Description

The useful model of a border router relates to data transmission systems, in particular, to a modular, scalable universal platform for building various network segments of a data network.

The closest technical solution is a service router (RF patent for utility model No. 210484, priority 12/30/2021), which is taken as a prototype.

The purpose of the utility model is to expand the functionality of the device to provide multi-service routing at the network edge and organize secure data storage.

The technical result is the creation of a scalable universal platform for combining various isolated segments of a data transmission network and organizing highly reliable distributed storages.

This goal is achieved by the fact that in a device containing two connected processors interconnected by inputs/outputs, input and output ports, a power supply unit, a RAM unit, a remote control unit, a serial interface unit, a data storage unit, a unit of two south bridges, located on the board, there are additionally four network interface expansion units and a data storage system unit using RAID technology, which are connected to the south bridge units of the processor via PCIe x8 xi interfaces with a power supply via a linear voltage regulator, and four PCIe x8 interfaces are located horizontally at the end of the board , and the fifth PCIe x8 interface is located vertically in the cutout of the board in the installation area of the data storage system block using RAID technology.

The presence of four expansion units located horizontally at the end of the board for expansion units with PCIe x8 interfaces allows you to connect additional communication units in the same plane with other elements and ensure their connection with the unit by control processors through south bridge units. The fifth expansion unit allows you to install a controller that implements RAID technology to create a highly reliable storage system.

Additional blocks are also connected to the power supply through a linear voltage regulator, which allows you to connect various expansion modules with high-speed interfaces of different port capacities and properties.

The location of the PCIe x8 interfaces in this way allows you to install additional expansion units in the same plane with the board.

Due to the inclusion of expansion units and a data storage unit, the router becomes a universal device for creating and connecting to heterogeneous public and internal communication networks and secure data storage.

Comparison of the proposed solution with other technical solutions shows that the listed elements used in the blocks, although they are known, however, their introduction in the specified connection with the remaining elements leads to an expansion of the functionality of the router in question. This confirms the compliance of the technical solution with the criterion of "novelty" and the presence of significant differences.

The utility model is illustrated by drawings.

In FIG. 1 shows a block diagram of the proposed device;

in Fig.2. shows a general view of the router board, where

1. Block 1 processor;

2. Block 2 processors;

3. Power supply;

4. Remote control unit;

5. Block of RAM;

6. Block of secure data storage;

7. Block of the south bridge;

8. Block of the south bridge;

9. Block of external interfaces;

10. Expansion module block;

11. Expansion module block;

12. Extension module block;

13. Extension module block.

The device works as follows. The first processor unit (1) is connected to the second processor unit (2) via a high-speed independent IP Lane interface. Each of the processors is connected to one of the southbridge blocks (7,8). The south bridge blocks implement external PCIe x8 interfaces, which are structurally designed in a horizontal design for connecting expansion blocks. The remote control unit (4) has a connection with the south bridge units (7,8) via the SPI line. The remote control unit (4) is connected to the RAM unit (5) via the DDR3 interface. The external interface block (9) is directly connected to the south bridge block (7) via a serial gigabit independent interface, as well as to the USB serial bus and the secure data storage unit (6) via the SATA line. To implement secure data storage, a RAID 5 scheme is implemented - a disk array with data block striping and parity. The power supply (3) is connected to all blocks with outputs according to the consumed voltage. 10GbE expansion module blocks (10,11,12,13) are connected to southbridge blocks (7,8) via PCIe x8 interface.

Expansion blocks allow you to connect the following modules:

Wi-Fi modules (2.4 GHz, 5 GHz);

E1 digital stream modules (G.703, G.704);

Internet of things (IoT) modules¸ in particular LORAWAN;

transmission modules of various types and speed characteristics (1Gbe, 10Gbe, RJ-45, SFP, SFP+).

Thus, the router with the introduction of the ability to connect additional expansion units via the PCIeх8 interface becomes a universal device for creating and connecting to heterogeneous public and internal communication networks, which makes it possible to achieve the stated technical result - to create a scalable universal platform for building and combining various network segments of the data transmission network, as well as to realize the possibility of safe data storage using the RAID5 system.
