Based on this, some embodiments of the present utility model provide a gateway device, and the gateway device is described below.

Illustratively, the plurality of electronic components include capacitive, resistive, triode, chip, relay, etc., each of which may be coupled, for example, by a trace in the PCB.

The small cell unit 103, the wlan unit 102 and the network-attached storage unit 104 are modules for implementing different functions, and they need to receive and process the digital signals transmitted from the broadband access unit 101, and then output the processing results to the back plane unit 105. Through the connection mode, data can be efficiently transmitted among the modules, and a plurality of functions can be cooperatively completed.

In some embodiments, as shown in fig. 2, the back plane unit 105 at least includes a switching power supply unit, a first PCI-E slot, a second PCI-E slot, a third PCI-E slot, and a fourth PCI-E slot, the broadband access unit 101 is plugged into the back plane unit 105 through the first PCI-E slot, the small base station unit 103 is plugged into the back plane unit 105 through the second PCI-E slot, the wireless lan unit 102 is plugged into the back plane unit 105 through the third PCI-E slot, and the network additional storage unit 104 is plugged into the back plane unit 105 through the fourth PCI-E slot.

The network attached storage unit 104 is connected to the backplane unit 105 through a fourth PCI-E slot and is responsible for providing NAS network storage functions.

The second PCI-E slot to the fourth PCI-E slot are designed as X4 specification slots, namely, 32 pairs of pins are included.

By using the back board unit 105, the four core units can be quickly and conveniently spliced together to form a complete system, so that the goal of fusion of multiple new technologies such as megalight broadband, WIFI6 wireless communication, 5GNR small base station communication, NAS network storage and the like is realized. Meanwhile, due to the design of the back board unit 105, the units can be connected with each other, so that more flexible system combination and expansion are realized, and more possibility is provided for future system upgrading and expansion. It should be noted that, the gateway device of the present utility model does not limit the number of PCI-E slots, and the number of PCI-E slots is configured according to the number of actual module function units.

In some embodiments, broadband access unit 101 is electrically connected to small base station unit 103 via a PCI-E interface to establish a small base station communication traffic channel;

the broadband access unit 101 is electrically connected with the wireless local area network unit 102 unit through an Ethernet interface to establish a WIFI6 high-speed service channel;

the broadband access ticket is electrically connected to the network attached storage unit 104 through the PCI-EX2 interface to establish a network storage service channel.

Specifically, as shown in fig. 3, the hardware connection relationship between the broadband access unit 101 and other functional units is that the broadband access unit 101 is connected to the other functional units through a PCI-EGen3X4 interface connection, a 2.5GbE ethernet interface connection, and a PCI-EX2 interface, respectively. The purpose of these connections is to establish different communication traffic channels, thereby implementing different functions.

First, the PCI-EGen3X4 interface is used for connecting communication between the broadband access unit 101 and the 5G small base station unit 103. The connection mode provides theoretical interface bandwidth of up to 4GB/s, and can realize high-speed data transmission and real-time communication. By the connection mode, a small base station communication service channel can be established, so that the communication function of the 5G network is realized. Second, a 2.5GbE ethernet interface is used for connecting communication between the broadband access unit 101 and the wireless lan unit 102. The connection mode can establish a WIFI wireless service channel and support WIFI6 high-speed service backhaul. The connection mode has the advantages of high speed, stability and reliability, and can provide excellent network transmission performance, thereby realizing the communication function of a high-speed wireless network. Finally, the PCI-EX2 interface is a communication for connecting the broadband access unit 101 and the network-attached storage unit 104. The connection mode can establish a network storage service channel and realize a network storage function. By the connection mode, the data can be rapidly transmitted and stored, so that the sharing and the backup of the data are realized.

In some embodiments, broadband access unit 101 distinguishes between different traffic channels through virtual local area network isolation.

The broadband access unit 101 is used as a convergence point of various services such as wired internet access, wireless internet access, small base station communication, network storage, and the like, and separates and distinguishes different service data streams through VLAN (virtual local area network). The broadband access unit 101 can isolate different service channels in different logic subnets through virtual local area network isolation, so that isolation and security between services are realized. VLAN technology may divide a physical local area network into multiple logical subnets, each with independent virtual bridging functions. In the broadband access unit 101, different traffic channels may be divided into different virtual local area networks by using different vlan ids. For example, 5G small cell communication traffic channels are divided into VLAN1, WIFI wireless traffic channels are divided into VLAN2, network storage traffic channels are divided into VLAN3, and so on. Thus, different service channels can be isolated through different virtual bridging functions, and interference and conflict between services are avoided.

VLAN isolation can also improve network security because different traffic channels can be isolated in different logical subnets, avoiding network attacks and data leakage. For example, in a network storage service channel, if important data is placed in a separate subnet, an attacker can be prevented from acquiring the important data by means of network attack.

In some embodiments, as shown in FIG. 3, the backplane unit 105 further includes a switching power module that is connected to the power pins of the first PCI-E slot, the second PCI-E slot, the third PCI-E slot, and the fourth PCI-E slot to provide +12V and +3V operating voltages.

A stable and reliable power supply is an important guarantee to ensure that the device is working properly, so the switching power supply module in the back plane unit 105 is also very important. The power of the switching power supply module is not more than 300W, and the active PFC, the mute fan, the intelligent temperature control and the support back line and wide voltage design are adopted, so that reliable power supply can be provided for the whole equipment. The +12V and +3.3V voltages output by the switching power module are the operating voltages required for the entire device, and thus, it is necessary to connect them to the power supply pins of the first to fourth PCI-E slots. When connection is realized, circuit board wiring operation is needed, and SMclk pins and REFclk pins of the first PCI-E slot to the fourth PCI-E slot are correspondingly connected so as to ensure that the equipment can work normally.
