A network switch is a device that provides functions of data forwarding, switching, routing, etc. in a data center network. Fig. 1 discloses a schematic diagram of a network switch 1. As shown in fig. 1, the network switch 1 includes a front panel 11 and a rear panel 12. A plurality of network ports 16 are provided on the front panel 11. The network switch 1 is configured to place all the network ports 16 on the front panel 11 in consideration of convenience in inserting and removing and maintaining the optical module on site and in consideration of the direction of airflow for radiating heat from the optical module in the air cooling mode. However, as network bandwidth usage continues to increase, the number of these network ports 16 disposed on the front panel 11 has not been sufficient for the transmission of higher rates of electrical signals within the switch system.

In view of this, one embodiment of the present description provides a network switch 2. Fig. 2 discloses a schematic diagram of a network switch 2 according to an embodiment of the present description. As shown in fig. 2, the network switch 2 according to an embodiment of the present disclosure includes a chassis 20 and a motherboard (not shown) located in the chassis 20.

The chassis 20 includes opposing front and rear panels 21, 22. In one embodiment, the chassis 20 is substantially rectangular parallelepiped. The cabinet 20 may further include a pair of side plates 23 respectively connecting the front panel 21 and the rear panel 22, and a top plate 24 and a bottom plate 25 respectively connecting the front panel 21, the rear panel 22, and the pair of side plates 23.

A plurality of network ports 26 are disposed on the front panel 21 and the rear panel 22, and the plurality of network ports 26 can be respectively used for plugging and unplugging a plurality of optical modules. The network port 26 according to the embodiment of the present disclosure may be applied to an optical module with a medium-high speed or higher network interface standard, and may be used to support hot plug of the optical module.

The number of network ports 26 of the front panel 21 and the number of network ports 26 of the rear panel 22 may or may not be the same. In one embodiment, the number of network ports 26 of the front panel 21 and the number of network ports 26 of the rear panel 22 are each more than eight. In another embodiment, the number of the network ports 26 arranged on the front panel 21 may be greater than the number of the network ports 26 arranged on the rear panel 22 in consideration of convenience in inserting and extracting the network ports 26 of the front panel 21. In addition, it is also possible to arrange network ports 26 that may need frequent plugging on the front panel 21, and to arrange network ports 26 that do not need frequent plugging on the rear panel 22.

The network switch 2 of the embodiment of the present disclosure may provide more network ports 26 for the pluggable optical module by providing the network ports 26 on the front panel 21 and the rear panel 22 at the same time.

In some embodiments, the plurality of network ports 26 of the present disclosure may include, for example and without limitation, at least one type of QSFP (Small form factor plug) form port, QSFP-DD (Small form factor plug Double definition) form port, OSFP (Oct Small form factor plug) form port, and OSFP-XD form port, which may be respectively used to support corresponding pluggable optical modules. The QSFP form port, the QSFP-DD form port, the OSFP form port and the OSFP-XD form port are all standards of a high-speed network interface.

The network ports 26 of the front panel 21 and the network ports 26 of the rear panel 22 are regularly arranged. In one embodiment, the plurality of network ports 26 of the front panel 21 and the plurality of network ports 26 of the rear panel 22 may be respectively arranged symmetrically.

In some embodiments, the network switch 2 of the present description may also include a liquid cold plate (not shown) located within the chassis 20 for heat dissipation. The network switch 2 of the present specification uses a liquid cooling plate to dissipate heat, so that the direction of the wind flow of the front panel 21 and the rear panel 22 may not be considered.

The network switch 2 of the present embodiment may include a switch chip (not shown) on a motherboard. In some embodiments, the switch chip of the present specification may include, for example, a 51.2T (512 × 112G-PAM4 Serdes) switch chip, which may be used to support plugging and interconnection of 400G or 800G optical modules. In other embodiments, the switch chip of this specification may further include a 102.4T (512 x224G-PAM 4) switch chip, and a bandwidth used by the 102.4T chip is doubled compared to that used by the 51.2T switch chip, so that the bandwidth can be used for transmission of electrical signals at a rate of 224G-PAM4 in a switch system, and can be used to support plugging and interconnection of next-generation 800G or 1.6T optical modules.

The network switch 2 of the embodiment of the present specification arranges a large number of network ports 26 on the front panel 21 and the back panel 22 at the same time to substantially evenly distribute 128 network ports 26 on the front panel 21 and the back panel 22, and this symmetrical structure can make the high-speed electrical signal path inside the switch network shortest, so that it is possible to connect 224G-PAM4 signals to 128 panel ports, and the cost is relatively low.

The network ports 16 of the network switch 1 shown in fig. 1 are only distributed on the front panel 11, which can be very convenient for on-site operation and maintenance (plugging and unplugging optical modules and optical fibers), but for the internal hardware of the network switch 1, the distance for connecting high-speed signals to the ports through components such as PCBs and internal connectors from the switch chip is long, the complexity is high, and the signal loss is large. For the evolution of the signal rate to 112G-PAM4 or even 224G-PAM4 in the future, the excessively long and complicated internal high-speed signal path in this case may cause that the integrity of the signal from the switch chip to the network port 16 of the front panel 11 cannot be guaranteed, or even the use of the pluggable optical module on the network switch 1 cannot be supported (for example, co-packaged Optics (Co-packaged Optics) is used, but the cost, reliability and maintainability are much worse than those of the pluggable optical module).

In contrast, the network switch 2 according to the embodiment of the present disclosure distributes the network ports 26 on the front panel 21 and the rear panel 22, so that the distance of the high-speed signal path from the switch chip to the network ports 26 on the front panel 21 and the rear panel 22, respectively, can be greatly shortened, and the complexity of the high-speed signal path can be simplified. Such a network switch 2 with network ports 26 on both front and back panels, while intuitively less friendly to field operations and maintenance than the switch shown in fig. 1, is not inoperable and is still acceptable in practice.

Compared with the network switch 1 in fig. 1, in which all the network ports 16 are placed on the front panel 11, the network switch 2 in the embodiment of the present specification shown in fig. 2 is that the network ports 26 are placed on the front panel 21 and the rear panel 22 at the same time, so that the field plugging and maintenance of the optical module is not too much problem although it is slightly inconvenient, and the inside of the switch can be cooled by using the liquid cooling plate, regardless of the wind flow direction of the front and rear panels.

The network switch 2 according to the embodiment of the present disclosure effectively solves the problem of high-speed signals and the problem of heat dissipation of optical modules for supporting 51.2T and next-generation 102T switch systems by arranging a large number of high-speed network interfaces on both the front panel 21 and the rear panel 22, and has a very high cost.

The network switch 2 according to the embodiment of the present specification can effectively solve the problem that the next generation 800G network switch 2 in the data center still supports the pluggable optical module, and provides a low-cost and highly reliable hardware system scheme for the 800G network.

Another embodiment of the present specification also provides a data center. The data center of the embodiments of the present specification may include the network switch 2 described in each of the above embodiments and a server connected to the network switch 2.

The data center according to the embodiments of the present disclosure has similar advantageous technical effects to the network switch 2 according to the above embodiments, and therefore, the description thereof is omitted here.

The above description of the embodiments is only intended to help understand the core ideas of the present specification. It should be noted that, for those skilled in the art, without departing from the spirit and principle of the present specification, several improvements and modifications can be made to the present specification, and these improvements and modifications should fall within the protection scope of the claims set forth in the specification.
