[0021] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] With the rapid development of video streaming, high-speed LAN access devices (2.5G routers, switches), Wi-Fi6 and the next generation of Wi-Fi, user devices are also equipped with higher-speed network cards or standards. However, the traditional ONU only provides a maximum 1G electrical interface on the user side, and the WAN port (optical interface) provides a transmission rate far greater than 1G. The Gigabit ONU user-side interface has become the bottleneck of the entire system, which has seriously affected fiber-to-the-home, especially fiber-to-the-office, i.e., government and enterprise access data services.

[0023] In view of the above bottlenecks, the present invention proposes a method for converting the 1G Ethernet interface in the ONU of the PON into a 2.5G Ethernet interface, that is, an additional 2.5GPHY chip is connected to the ONU to form a new ONU device, which improves the user-side transmission rate and achieves rate matching with the user-side terminal equipment to solve the transmission bottleneck of 1G Ethernet.

[0024] An additional 2.5GPHY chip is connected to the ONU. The working mode, function configuration, and performance commissioning of the 2.5GPHY chip are usually configured through command lines, which is complex to operate and not conducive to human-computer interaction. The present invention proposes a method for configuring the ONU through a WEB interface. The method is simple to operate and has friendly human-computer interaction.

[0025] Figure 1 For the structural diagram of the optical fiber network unit provided in the embodiment of the present application, refer to Figure 1 The optical fiber network unit 10 includes a physical layer transmission module 11 and a processing module 12. The processing module 12 is connected to the physical layer transmission module 11 through a high-speed serial interface communication, and is connected to the physical layer transmission module 11 through a bidirectional data line and a clock line communication; the processing module 12 is used to query the management and maintenance data of the physical layer transmission module 11 based on the pre-created PROC virtual file system node 18, send the management and maintenance data to the user through the WEB browser 20, and configure the physical layer transmission module 11 in response to the user's configuration information. The processing module 12 is also used to receive electrical signals, process the electrical signals to obtain Ethernet data, and send the Ethernet data to the physical layer transmission module 11; the physical layer transmission module 11 is used to receive Ethernet data and send Ethernet data to the user-side terminal device.

[0026] refer to Figure 1 In the embodiment of the present invention, a physical layer transmission module 11 is added to the optical network unit 10, and the physical layer transmission module 11 is configured, so that the transmission rate of the user-side electrical port of the optical network unit 10 can be greatly improved compared with the existing gigabit transmission rate, solving the problem that the existing user-side gigabit electrical port restricts the high-speed transmission of data in the entire system, thereby meeting the high-speed data access requirements of the user-side terminal device 30. The optical network unit 10 can improve the user network data throughput and reduce network latency by matching the Ethernet-side 2.5G high-speed access routers, switches, Wi-Fi6 and high-speed network cards and other devices, thereby improving the service quality of the user's audio and video services.

[0027] It should be noted that the processing module 12 of the present invention can be a SoC chip of PON, which can run the Linux operating system. After adding the physical layer transmission module 11, the configuration personnel can create a script program in the Linux operating system in advance, and create a kernel thread separately according to the script program. The kernel thread can run in the kernel space and does not occupy the user's address space. The script program usually uses the kthread_add or kthread_creat function when creating a kernel thread. The script program can use the proc_create function to create a node under the / proc file system, and the node is the PROC virtual file system node 18. After creating the PROC virtual file system node 18, the script program also needs to register the function node. For each function (such as tx_mode, rx_mode, etc.), the script program can create / proc nodes for them respectively, and assign corresponding read and write operation rights to them, so that each function node can execute specific read and write logic. It should be noted that when the physical layer transmission module 11 is uninstalled, the script program can delete these / proc nodes to avoid resource leakage. It should be noted that the above process can also be performed manually by the configuration personnel.

[0028] Furthermore, the physical layer transmission module 11 is a physical layer chip, and the data transmission rate of the physical layer chip is not less than 2.5 Gbps.

[0029] Among them, the physical layer chip (Physical Layer Interface Devices, PHY chip) is a key chip in computer networks and communication equipment, responsible for implementing the data transmission function of the physical layer. The PHY chip is located at the bottom layer of the OSI model and is responsible for processing the physical transmission of data. The PHY chip connects and exchanges data with the MAC layer or other control layer chips through various interfaces (such as MII, RMII, GMII, etc.).

[0030] Exemplarily, the processing module 12 may be specifically an RTL9601D SoC chip, which is mainly used for the optical network unit 10 (ONU) of GPON and EPON. The SoC chip supports providing gigabit data access services through the PON network, and is suitable for optical fiber access of a home or small office / home office (SOHO). Since the SoC chip can only provide gigabit data access services and cannot meet the user's high-speed access requirements, the present invention proposes an improved technical solution to solve the above technical problems. The physical layer transmission module 11 may be specifically an RTL8821B chip, which may be used to provide a 2.5G Ethernet interface. The RTL8821B chip is connected to the RTL9601D SoC chip via a high-speed serial interface communication, and is connected to the RTL9601D SoC chip via a bidirectional data line and clock line communication. The RTL8821B chip replaces the 1G Ethernet interface in the ONU with a 2.5G Ethernet interface, thereby increasing the data transmission rate of the user-side terminal device 30, thereby matching the user-side terminal device 30 in terms of rate, and solving the data transmission bottleneck problem of the existing ONU.

[0031] Specifically, the physical layer transmission module 11 is connected to two general input and output interfaces of the processing module 12 through a bidirectional data line and a clock line respectively.

[0032] The following is an exemplary description using an example in which the physical layer transmission module 11 is an RTL8821B chip and the processing module 12 is an RTL9601D SoC chip.

[0033] Specifically, one end of the bidirectional data line and clock line is connected to the MDIO interface and MDC of the RTL8821B chip respectively, and the other end is connected to the upstream RTL9601D SoC chip through the HSGMII interface to complete the transmission of 2.5G rate data. Among them, the MDC and MDIO interfaces can provide a management interface to the RTL8821B chip, which is used to manage and maintain the RTL8821B chip.

[0034] Furthermore, the RTL9601D SoC chip can run the Linux operating system. In the Linux operating system, the user can query the data of the RTL8821B chip through the WEB browser 20, and send management and maintenance data to the user through the WEB browser 20. The user configures the RTL8821B chip in a targeted manner based on the RTL8821B chip data queried by these management and maintenance data, and uses the operation interface of the WEB browser 20 to configure the RTL8821B chip, which has the advantages of simple operation and friendly human-computer interaction. The RTL9601D SoC chip is also used to register the SoC chip with the optical line terminal OLT, establish a communication link with the optical line terminal OLT, and complete the analysis of the communication protocol and the transmission and reception of data.

[0035] Continue to refer Figure 1 In the embodiment of the present invention, the optical network unit 10 further includes an optical forwarding module 16 and a storage module 15 which are communicatively connected to the processing module 12, and the optical transceiver module 14 is communicatively connected to the optical forwarding module 16: the optical transceiver module 14 is used to receive / send optical signals, the optical forwarding module 16 converts the optical signals into electrical signals, and sends the electrical signals to the processing module 12; the storage module 15 is used to receive and store the electrical signals sent by the optical forwarding module 16. In response to the call of the processing module 12, the optical forwarding module 16 converts the electrical signals into optical signals and sends them out through the optical transceiver module 14. Under the control of the processing module 12, the electrical signals in the storage module 15 are transmitted to the user through the physical layer transmission module 11.

[0036] The physical layer transmission module 11 is an RTL8821B chip, and the processing module 12 is an RTL9601D SoC chip.

[0037] Exemplarily, the RTL9601D SoC chip receives the optical fiber signal in the PON, and then uses the serializer / decoder (PONSERDES) interface to complete the reception / decoding of the optical signal to obtain an electrical signal. After the conversion of the optical signal to the electrical signal is realized, the RTL9601D SoC chip forwards the user data to the 2.5GHSGMII interface on the user side. Specifically, the optical transceiver module 14 in the RTL9601D SoC chip receives the user data transmitted by the 2.5GHSGMII interface, and forwards the user data to the 2.5GE / RJ45 interface on the user side, that is, forwarded to the 2.5GE / RJ45 interface of the RTL8821B chip through the optical forwarding module 16, thereby realizing data communication with the user side terminal device 30. In addition, the storage module 15 can also first store the user data in the RTL9601D SoC chip, and then transmit the user data in the storage module 15 to the user side terminal device 30 at a high speed according to the call instruction of the RTL9601D SoC chip, thereby improving the user data transmission rate.

[0038] Furthermore, in an embodiment of the present invention, the optical fiber network unit 10 also includes a physical layer driver module 19 that is communicatively connected to the processing module 12; the physical layer driver module 19 can be used to obtain management and maintenance data of the physical layer transmission module, and send the management and maintenance data to a WEB server application 17 preset in the processing module 12; the processing module 12 receives the management and maintenance data, converts and processes the management and maintenance data to obtain target data, and sends the target data to the user through the WEB browser 20.

[0039] Specifically, the RTL9601D SoC chip runs a WEB server application 17 in the Linux operating system, and the WEB server application 17 communicates with the kernel driver module of the RTL8821B chip, namely, the physical layer driver module 19, to complete the acquisition of management and maintenance data. The physical layer driver module 19 first acquires the hexadecimal management and maintenance data, and then converts the hexadecimal data into data that can be displayed by the browser and displays it to the user through the WEB browser 20.

[0040] Specifically, the register of the physical layer transmission module 11 stores management and maintenance data, and the management and maintenance data includes at least one of working mode data, rate data, LED control data and performance commissioning data.

[0041] The RTL9601D SoC chip obtains the working mode data, rate data, LED control data and performance test data stored in the register of the RTL8821B chip through the kernel driver module of the RTL8821B chip. The user completes the setting of the RTL8821B chip by modifying one or more of the working mode data, rate data, LED control data and performance monitoring data on the WEB browser.

[0042] Based on the above embodiments, the present invention proposes a configuration method for an optical network unit, which is applied to the processing module 12 in the optical network unit 10 in any of the above embodiments. Figure 2 The flowchart of the configuration method of the optical fiber network unit provided in this embodiment is shown in FIG. Figure 2 The specific implementation process of the configuration method of the optical fiber network unit may include:

[0043] S10, in response to a user configuration request, creating a separate kernel thread;

[0044] S20, creating a PROC virtual file system node 18 based on the kernel thread;

[0045] S30. In response to the user configuration request, a WEB server application 17 is created. Based on the WEB server application 17, the management and maintenance data in the PROC virtual file system node 18 is read. The management and maintenance data is sent to the user through the WEB browser 20. In response to the user's configuration information, the physical layer transmission module 11 is configured through the PROC virtual file system node 18.

[0046] Specifically, the processing module 12 performs data interaction with the physical layer transmission module 11 through the PROC virtual file system node 18 created by the kernel thread by executing steps S10 to S30. Exemplarily, the WEB browser 20 can call the Linux commands cat and echo to operate the PROC virtual file system node 18 corresponding to the RTL8821 chip through the WEB server application 17, thereby realizing the reading and setting of the management and maintenance data in the register of the RTL8821 chip. Thereafter, the WEB server application 17 can convert the management and maintenance data into HTTP message format to interact with the host computer of the user end.

[0047] Furthermore, before step S10, the configuration method of the optical network unit 10 may further include the following specific execution steps:

[0048] S41, loading the driver modules of the physical layer transmission module 11, the optical transceiver module 14 and the optical forwarding module 16 respectively;

[0049] S42, establishing a management channel between the physical layer transmission module 11 and the processing module 12, wherein the management channel includes a bidirectional data line and a clock line respectively connected to two general input and output interfaces of the processing module 12, and initializing the management channel.

[0050] Specifically, when initializing the Linux system on the RTL9601D SoC chip, the optical network unit 10 needs to load the driver modules of the physical layer transmission module 11, the optical transceiver module 14, and the optical forwarding module 16 in advance, and the optical network unit 10 also needs to initialize the MDC and MDIO interfaces. In this way, the optical network unit 10 can establish a management channel between the RTL9601D SoC chip and the RTL8821B chip. After the above initialization work is completed, the RTL9601D SoC chip can start to send and receive PON data.

[0051] Furthermore, after creating the PROC virtual file system node 18 based on the kernel thread, the configuration method of the optical network unit 10 may further include the following specific implementation steps:

[0052] S51, creating a function node based on the PROC virtual file system node 18;

[0053] S52, adding query and setting functions to the function node;

[0054] S53, reading the management and maintenance data in the functional node based on the WEB server application 17, sending the management and maintenance data to the user through the WEB browser 20, and configuring the physical layer transmission module 11 through the functional node in response to the user's configuration information.

[0055] Exemplarily, after creating the PROC virtual file system node 18 based on the kernel thread, the processing module 12 of the optical network unit 10 also needs to create each functional node and set the transmission mode (tx_mode), receiving mode (rx_mode), low power mode (pwr_save) and / or LED configuration (led) information of each functional node. The PROC virtual file system node 18 corresponding to each functional node can be exemplarily: proc / rtl8221b / tx_mode, proc / rtl8221b / rx_mode, proc / rtl8221b / pwr_save and / proc / rtl8221b / led, etc. After creating each functional node, the WEB server application 17 needs to register with each node and add set and get functions. The WEB browser 20 in the upper computer of the user end can operate each node corresponding to the PROC virtual file system / proc / rtl8221b / through the cat and echo commands in the WEB server application 17 to complete the query and configuration of the management and maintenance data of the registers in the RTL8821B chip.

[0056] It should be noted that after configuring the physical layer transmission module 11 through the PROC virtual file system node 18, the configuration method of the optical network unit 10 may further include the following specific implementation steps:

[0057] S60, in response to the user test request, the network performance of the physical layer transmission module 11 is tested through the PROC virtual file system node 18. The WEB browser 20 in the upper computer of the user end completes the test and debugging of the RTL8821B chip through the WEB server application 17. Specifically, the main target of the test and debugging can be the network performance of the RTL8821B chip.

[0058] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
