IMPLEMENTATION OF THE USEFUL MODEL

The following detailed description of the implementation of the utility model provides numerous implementation details to provide a clear understanding of the present utility model. However, it will be obvious to a skilled person in the domain of how the present utility model can be used, with or without these implementation details. In other cases, well-known methods, procedures and components have not been described in detail so as not to obscure the unnecessary understanding of the features of the present utility model.

In addition, from the above presentation it will be clear that the utility model is not limited to the given implementation. Numerous possible modifications, changes, variations and replacements, which retain the essence and form of the present utility model, will be obvious to specialists qualified in the subject area.

The present technical solution is implemented as a device for switching and routing packets with 100 Gbps (100GbE) interfaces.

A packet switching and routing device in this solution means a type of network telecommunications device that is implemented without embedded software, but with a bootable software environment that allows the installation of compatible network operating systems based on the Linux kernel. This enables users to swap out the network operating system and avoid vendor lock-in. This approach allows the implementation of the construction of software-defined networks and virtualization of network functions.

The hardware architecture of the packet switching and routing device uses a special purpose integrated circuit (ASIC) switch and control processor. Ready-made solutions from vendors (for example: Broadcom or Marvell) can be used as ASICs.

ASIC provides non-blocking switching (line-rate packet forwarding) when the device transfers information. The ASIC sits on a printed circuit board with network interfaces, in this case 100GbE. To be able to control the control processor by the logic of the ASIC, an API from the vendor is additionally implemented and software (driver) that provides control of the control processor by the ASIC ports. One of the tasks of this technical solution is the implementation of the interaction mechanism (driver) of the 100 GbE ASIC interfaces of the switch with the Elbrus control processor. The driver provides the representation of the switch ASIC for the control processor as a conventional PCIe device, namely, the representation of the switch circuit board with 18 x 100GbE network interfaces as a PCIe device and management / filling of its internal structures / registers by converting L2 / L3 tables from the operating system.

In this technical solution, the control processor is located on a separate com-express processor module. It should be noted that within the framework of this technical solution, it is possible to replace the control processor by installing a compatible com-express module.

The 100 Gbps packet switching and routing device is designed with an open programmable architecture and includes the following elements.

1. A board with an Elbrus control processor. The interface for interacting with the switch ASIC board is PCIe (board form factor - Com Express Type 6).

2. Board with a special purpose integrated circuit switch (Board with ASIC switch). The interface for interacting with the board with the control processor is PCIe. 18 x 100GbE network interfaces are located directly on the board.

3. A board for controlling five cooling fans connected to a board with a switch ASIC, through which power is supplied and commands are transmitted from a board with an Elbrus control processor to increase / decrease the number of fan revolutions depending on the temperature of the switching device and packet routing, and five cooling fans.

4. Power supplies - 2 pcs., Which are connected directly to the Board from the switch ASIC and supply power to the entire device for switching and routing packets with 100 Gbps interfaces.

It should be noted that all the above elements of the device for switching and routing packets are interconnected and are in structural unity (located in the body of the device).

FIG. 1 shows a block diagram of a device for switching and routing packets with 100 Gbps interfaces.

Power supply to the device.

Power from the AC 220V power supply is supplied to the power supplies, which operate in hot standby mode. At the output from the power supply, direct current 12 / 5V enters the printed circuit board with a special purpose integrated circuit (ASIC), which distributes it to the fan control board, the board with the Elbrus control processor and directly to itself (to the printed circuit board with the special purpose integrated circuit (ASIC).

Functioning of the device.

On the board with the Elbrus control processor, rules for redirecting packets entering the device (switching and routing tables) are formed. With the help of the driver, the specified tables are written into the registers of the special purpose integrated circuit (ASIC). Based on the recorded values, the switch's special-purpose integrated circuit (ASIC) printed circuit board, which houses the 18 x 100GbE network interfaces, processes (forwards) incoming traffic through the network interfaces.

In the present application materials, a preferred disclosure of the implementation of the claimed technical solution was presented, which should not be used as limiting other, particular embodiments of its implementation, which do not go beyond the scope of the claimed scope of legal protection and are obvious to specialists in the relevant field of technology.
