To solve the above technical problem, an embodiment of the present application discloses a reinforced switch, the switch includes: the device comprises a switching chip, a physical layer chip, an Ethernet port and an optical fiber port; the Ethernet port is used as an input port and is connected with the switching chip through the corresponding physical layer chip; the physical layer chip is used for converting the data frame in the form of a digital signal input by the Ethernet port from the digital signal form to the analog signal form and outputting the data frame in the form of the analog signal to the exchange chip; and the switching chip is used for forwarding the data frame in the form of the input analog signal to the optical fiber port.

In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments.

a 10Gbase-KR interface, namely a 10Gb/s (10 Gbps) back plane Ethernet interface;

10GBase-T interface, namely 10Gb/s (10 Gbps) tera Ethernet interface or RJ45 interface;

PHY chip, i.e. digital-analog hybrid circuit, physical layer chip;

micro-control unit (Microcontroller Unit, MCU), also called single-chip microcomputer or single-chip microcomputer

The local area network address (Media Access Control Address, MAC), i.e. the medium access control address, is an address used to identify the location of the network device.

Referring to fig. 1, the structure of a reinforced switch according to an embodiment of the present application is shown.

As shown in fig. 1, the switch includes: a switch chip 101, a physical layer chip 102, an ethernet port 103, and an optical fiber port 104; the ethernet port 103 is used as an input port and connected to the switch chip 101 through the corresponding physical layer chip 102, and the optical fiber port 105 is directly connected to the switch chip 101.

Wherein,

a physical layer chip 102 for converting a data frame in the form of a digital signal inputted from the ethernet port 103 from the digital signal form to an analog signal form and outputting the data frame in the form of the analog signal to the switching chip 101;

the switch chip 101 is configured to forward a data frame in the form of an input analog signal to the fiber port 104.

It should be appreciated that the signals of the fiber ports are transmitted in optical form, while the signals of the ethernet ports (RJ 45) are transmitted in electrical form. Wherein the optical signal is an analog signal and the electrical signal is a digital signal.

Firstly, the upper computer inputs the data frame of the digital signal through the Ethernet port 103, the physical layer chip 102 corresponding to the Ethernet port 103 converts the data frame of the digital signal into the data frame of the analog signal form, and outputs the data frame of the analog signal form to the exchange chip 101; secondly, the exchange chip 101 analyzes the data frame in the form of analog signals to obtain a source MAC address of the Ethernet port and a target MAC address of the target port; then, matching is carried out in an MAC address table according to the target MAC address, and when the target MAC address exists in the MAC address, a data frame in the form of an analog signal is unicast forwarded to a target port, namely an optical fiber port 104; finally, the optical fiber port 104 sends the data frame to an upper computer connected with the optical fiber port 104 to realize the interaction of the data frame.

In an alternative embodiment, when the destination MAC address is not present in the MAC address table, the switch chip 101 forwards the data frame broadcast in the form of an analog signal to all ports, i.e. all ports except the ethernet port 101 as input. The type of port is not limited in any way here, i.e. the port may be an ethernet port or a fiber optic port.

In an alternative implementation mode, according to the data frame in the form of analog signals, the MAC address corresponding to the Ethernet port is obtained; searching in an MAC address table according to the MAC address corresponding to the Ethernet port and obtaining a search result; and when the search result indicates that the MAC address does not exist in the MAC address table, adding the MAC address corresponding to the Ethernet port into the MAC address table.

As an example, the switch chip 101 may be a CTC7132 (TsingMa) chip, and the CTC7132 chip is a sixth generation core switch chip that is oriented to the cloud era and is introduced by the evolution demand of the edge computing technology. The chip supports 440Gbps I/O bandwidth, integrates an ARM dual-core A53 processor, supports port forms such as QSFMII and USXGMII, and provides full-rate port capability from 100M to 100G. The physical layer chip 102 may be any one of a YT868 PHY chip, a YT8614 PHY chip, an SF1204 PHY chip, or a YT8512H chip. It should be noted that CTC7132 and the PHY chip mentioned above are all domestic chips, which is helpful for realizing the localization of the device.

Note that CTC7132 has three self-contained ports that can enable data interactions between ethernet ports, or data interactions between fiber ports.

After the ports of the CTCs 7132 are expanded through the physical layer chip, data interaction between single-port and multi-port can be realized, and data interaction between multi-port and multi-port can also be realized, as shown in fig. 2 and 3 respectively.

Fig. 2 shows a schematic diagram of data interaction between a single port and a plurality of ports, and in fig. 2, a 1000Base-T interface may interact with a 1000Base-X interface or a 10GBase-T interface. It should be noted that the 1000Base-X interface is an optical fiber port, and the 1000Base-T interface and the 10GBase-T interface are both Ethernet ports, so that data interaction between the Ethernet interface and the optical fiber interface can be realized, and data interaction between the Ethernet interface and the Ethernet interface can be realized. Namely, a data frame input by the 1000Base-T interface contains the MAC address of the 1000Base-X interface, so that data interaction between the Ethernet interface and the optical fiber interface is realized; the data frame input by the 1000Base-T interface contains the MAC address of the 10GBase-T interface to realize the data interaction between the Ethernet interface and the Ethernet interface.

FIG. 3 is a schematic diagram of a multi-port to multi-port data interaction, in which in FIG. 3, a 1000Base-T interface may interact with a 1000Base-X interface or a 10GBase-T interface; the 10GBase-KR can interact data with the 1000Base-X interface or the 10GBase-T interface.

In addition, the switch in the embodiment of the application further comprises an MCU for monitoring the state of the switch chip. The MCU and the exchange chip are connected in the following two modes:

firstly, the MCU is connected with the exchange chip through a serial port UART;

and secondly, the exchange chip is connected with the MCU through the first physical layer chip PHY and the second physical layer chip PHY. By the method, when the first physical layer chip PHY cannot play a role, the state of the exchange chip can be monitored through the second physical layer chip PHY.

On the basis of MCU connection, peripheral equipment can also be connected through serial ports UART or bus GPIO. The state of the peripheral device can be monitored through the MCU.

In addition, the switch further includes: debugging a serial port; the debugging serial port is connected with the exchange chip through the serial port;

and the debugging serial port is used for checking the printing information of the exchange chip and can be used for configuring the port information.

According to the embodiment of the application, the data frames in the form of digital signals are converted into the data frames in the form of analog signals, so that the equipment adopting the Ethernet ports and the equipment adopting the optical fiber ports can realize data interaction through the reinforced switch.
