[0049] The present application will be described in detail below in conjunction with the specific implementation modes shown in the accompanying drawings, but these implementation modes do not limit the present application. Structural, methodological, or functional changes made by ordinary technicians in the field based on these implementation modes are included in the protection scope of the present application.

[0050] like Figure 1As shown, a fiber optic transceiver management device provided by an embodiment of the present application includes a fiber optic transceiver 11, an optical transmission network device 12, and a network management device 13. The optical transmission network device 12 includes an Ethernet tributary card 121 and a main control card 122. The Ethernet tributary card 121 is connected to the fiber optic transceiver 11 through an optical port / electrical port. The fiber optic transceiver 11 periodically generates a first EFM extended protocol message and sends it to the Ethernet tributary card 121 through the optical port / electrical port, wherein the first EFM extended protocol message carries the first status information of the fiber optic transceiver 11, and the first status information includes the device information of the fiber optic transceiver 11 and the status information of the optical port / electrical port. The Ethernet tributary card 121 receives the first EFM extended protocol message from the fiber optic transceiver 11, and in response to the first EFM extended protocol message, parses the message, obtains the first status information of the fiber optic transceiver 11 in the message, and encapsulates the first status information of the fiber optic transceiver 11 into a first message and sends it to the main control card 122. The main control card 122 receives the first message from the Ethernet branch card 121, and in response to the first message, parses the first message, obtains and stores the first status information of the optical fiber transceiver 11 in the first message, and sends the status information notification of the optical fiber transceiver 11 to the network management device 13. In response to the status information notification, the network management device 13 obtains the first status information of the optical fiber transceiver 11, stores the first status information in the database, and displays the first status information on the front-end interface of the network management device 13. It should be noted that in the embodiment of the present application, the optical fiber transceiver 11 and the optical transmission network device 12 support EFM (Ethernet in the First Mile) function. It can be understood that an optical transmission network device 12 can be connected to dozens of optical fiber transceivers 11. Based on the active reporting of the respective status information by each optical fiber transceiver 11, the optical transmission network device 12 obtains the status information of each optical fiber transceiver 11, and then notifies the status information to the network management device 13. The network management device 13 stores the status information of each optical fiber transceiver 11 and displays it on the interface. In this embodiment, the optical fiber transceiver 11 periodically reports its own status information, for example, the status information of the electrical port / optical port, and the optical transmission network device 12 can obtain the status information in time. The network management device 13 obtains the status information of the optical fiber transceiver 11 through the optical transmission network device 12, thereby realizing the management of the optical fiber transceiver 11 by the optical transmission network device 12 and the network management device 13, and can obtain the status information of the optical fiber transceiver 11 in time. The network management device 13 manages the optical fiber transceiver 11 and obtains the status information through communication with the optical transmission network device 12, and manages the optical fiber transceiver 11 in an out-of-band management manner. Therefore, the network management device 13 does not need to directly connect with multiple optical fiber transceivers 11 through multiple TCP connections, and can manage each optical fiber transceiver 11. The network management device 13 reduces the connection of TCP data, thereby reducing the consumption of system resources.

[0051] like Figure 2 A schematic diagram of a network topology of an embodiment of the present application is shown, in which the fiber optic transceivers 11 periodically report their respective status information to the optical transmission network device 12, the optical transmission network device 12 manages and obtains status information of the downstream fiber optic transceivers 11, and the network management device 13 manages each fiber optic transceiver 11 based on the out-of-band network through each optical transmission network device 12 in the network.

[0052] Before the fiber optic transceiver 11 periodically sends the first EFM extended protocol message, an EFM connection is established between the Ethernet tributary card 121 and the fiber optic transceiver 11. The OAM entity in the handshake stage periodically sends information OAMPDU (Information OAMPDU) messages to detect the connectivity of the link. Exemplarily, the Ethernet tributary card 121 is in active mode, and the fiber optic transceiver 11 is in passive mode. The Ethernet tributary card 121 periodically sends information OAMPDU messages to each fiber optic transceiver 11 hanging under it to establish a dialogue connection with each fiber optic transceiver 11. The EFM intercommunication connection between the Ethernet tributary card 121 and the fiber optic transceiver 11 adopts the standard 802.3ah protocol message, and its protocol message is called OAMPDU (OAM Protocol Data Units). As Figure 3 The schematic diagram of the OAMPDU message structure is described, in which the message mainly includes the destination address (DA), source address (SA), type (Type), subtype (Subtype), flag (Flags), code (Code), data (Data / Pad), redundancy check (CRC) and other fields. In the embodiment of the present application, the code 0x00 represents the information OAMPDU message, and the code OxF1 represents the first EFM extended protocol message. The information OAMPDU message includes the local information type length value field (Localinfo Type Length and Value, Local info TLV) and the remote information type length value field (Remote info TLV). For the specific structure, see Figure 4 The structure diagram of the information OAMPDU message is shown.

[0053] In some embodiments, the Ethernet tributary card 121 generates a first information OAMPDU message and sends it to the optical fiber transceiver 11. The first information OAMPDU message carries the local device information and the VLAN ID. Exemplarily, the Ethernet tributary card 121 is configured to be used for the VLAN for in-band management with the optical fiber transceiver 11, for example, the VLAN ID is set to 4094. The Ethernet tributary card 121 sets the local device information and the VLAN ID in the first information OAMPDU message, such as Figure 4In the message structure shown, the information of the local device, such as the manufacturer name and the corresponding device name, is set in the OUI field and the vendor information field.

[0054] In some embodiments, the optical fiber transceiver 11 receives the first information OAMPDU message sent by the Ethernet tributary card 121, parses the first information OAMPDU message, obtains the VLAN ID of the first information OAMPDU message, and performs VLAN configuration of the device itself based on the VLAN ID. For example, the optical fiber transceiver 11 configures the VLAN ID to 4094 for in-band data transmission with the Ethernet tributary card 121. Figure 4 In the message structure shown, the device serial number and supplier name of the fiber optic transceiver 11 are added to the OUI field and supplier information field in the information OAMPDU message. The source address in the information OAMPDU message is the MAC address of the fiber optic transceiver 11. A second information OAMPDU message is generated and sent to the Ethernet branch card 121.

[0055] In some embodiments, the Ethernet tributary card 121 receives the second information OAMPDU message, parses the second information OAMPDU message, obtains the MAC address, device serial number and vendor name of the optical fiber transceiver 11 in the second information OAMPDU message, and stores them. Based on the second information OAMPDU message, it is determined that the EFM protocol intercommunication with the optical fiber transceiver 11 has been successfully established. Because the EFM function device under the optical transmission network device may not only be a fiber optic transceiver, but also other devices, such as a switch, it is determined whether it is a fiber optic transceiver based on the OUI field in the information OAMPDU message. The Ethernet tributary card 121 encapsulates the obtained MAC address, device serial number and vendor name of the optical fiber transceiver into a second message and sends it to the main control card 122. Exemplarily, a TCP connection is established between the Ethernet tributary card 121 and the main control card 122, and the second message may be a TCP message.

[0056] In some embodiments, the main control card 122 receives and parses the second message, obtains the MAC address, device serial number and supplier name of the optical fiber transceiver 11 in the second message, stores them, and sends an online notification of the optical fiber transceiver 11 to the network management device 13. Exemplarily, the main control card 122 sets a database, in which the MAC address, device serial number and supplier name of the optical fiber transceiver 11 are stored. Based on this embodiment, the main control card 122 obtains the online information of the optical fiber transceiver 11 through the Ethernet tributary card 121, so that the optical transmission network device 11 can manage the optical fiber transceiver 11.

[0057] In some embodiments, the network management device 13 responds to the online notification, queries and obtains the device serial number and supplier name of the optical fiber transceiver 11 from the main control card 122 based on the management channel, stores the device serial number and supplier name of the optical fiber transceiver 11 in the database, and displays it on the front-end interface of the network management device 13. Exemplarily, the main control card 122 establishes communication with the network management device 13 in an in-band or out-of-band manner, and the main control card 122 can then learn the IP address of the network management device 13, so that data communication can be carried out between the two. For example, the management channel between the main control card 122 and the network management device 13 can be based on the GCC channel of the network port or the optical transmission network device port. The network management device 13 subscribes to the notification of the optical transmission network device 12 in advance, and the optical transmission network device 12 can actively send the online notification or status information notification of the optical fiber transceiver 11. Based on this embodiment, the network management device 13 obtains the online notification of the optical fiber transceiver 11 through the main control card 122, so that the management of the optical fiber transceiver 11 can be realized.

[0058] In some embodiments, the structure of the first EFM extended protocol message may be as follows: Figure 5 As shown, the code OxF1 represents the first EFM extended protocol message. The meaning of the other fields of the first EFM extended protocol message except the data field is consistent with the OAMPDU message. In this application, the transmission of the status information of the optical fiber transceiver 11 is mainly realized through the data field in the message. The data field of the first EFM extended protocol message includes a first TLV (type length value) field for indicating device information, a second TLV field for indicating optical port status information, and a third TLV field for indicating electrical port status information. The first TLV field includes the IP address, hardware version, software version, device serial number, vendor name and device type of the optical fiber transceiver 11. The second TLV field includes the link status, temperature, optical port receiving power, optical port transmitting power, optical port port number and EFM port number of the optical port. The EFM port number indicates whether the optical port is a port for EFM protocol communication with the Ethernet tributary card 121. The third TLV field includes the link status, temperature, port number and EFM port number of the electrical port, and the EFM port number indicates whether the electrical port is a port for EFM protocol communication with the Ethernet tributary card 121. Exemplarily, the link status of the electrical port refers to whether the link connection is up or down. Based on the extended data segment of the first EFM extended protocol message, the device information, electrical port status and optical port status of the optical fiber transceiver 11 can be obtained, so that the optical transport network device 12 and the network management device 13 can obtain the status information of the optical fiber transceiver 11 in a timely manner.

[0059] In some embodiments, the Ethernet tributary card 121 updates the layer 2 forwarding table, adds the MAC address of the optical fiber transceiver 11 and the corresponding layer 2 egress port number in the table entry of the layer 2 forwarding table, and carries the MAC address and IP address of the optical fiber transceiver 11 in the third message and sends it to the main control card 122. The Ethernet tributary card 121 learns the MAC address of the optical fiber transceiver 11 through the second information OAMPDU message sent by the optical fiber transceiver 11, and learns the IP address of the optical fiber transceiver 11 through the first EFM extended protocol message. The Ethernet tributary card 121 configures the layer 2 egress port number corresponding to the MAC address and updates the layer 2 forwarding table. The main control card 122 receives the third message, obtains the MAC address and IP address of the optical fiber transceiver 11 in the third message, and generates a routing information based on the MAC address and the IP address, wherein the routing information includes the association between the IP address and the MAC address of the optical fiber transceiver 11, that is, the MAC address corresponding to the IP address of the optical fiber transceiver 11 is the MAC address of the optical fiber transceiver 11, and includes the three-layer egress port number corresponding to the IP address, so that the main control card 122 accesses the optical fiber transceiver 11 through the IP address and obtains the second state information of the optical fiber transceiver 11, wherein the routing information is recorded in the static routing table, and the second state information is at least one of the following: the CPU usage rate of the optical fiber transceiver 11, the electrical port transceiver packet count, and the optical port transceiver packet count. Exemplarily, the second state information can be obtained by logging in to the IP address through telnet, and the communication data processing based on the Linux kernel protocol stack. In this embodiment, the information of the optical fiber transceiver 11 can be queried by logging into the IP address of the optical fiber transceiver 11, and more status information of the optical fiber transceiver 11 can be obtained, such as the CPU usage rate of the optical fiber transceiver 11, the electrical port receiving and sending packet count, the optical port receiving and sending packet count, etc. By automatically configuring the static routing information of the static routing table, the OSPF (Open Shortest Path First) routing protocol intercommunication is avoided, and IP communication can be performed with the optical fiber transceiver 11 without running the OSPF routing protocol on the CPU, thereby reducing the CPU resource consumption of the main control card 122.

[0060] In some embodiments, in response to detecting fault information, the fiber optic transceiver 11 sends a pre-configured second EFM extended protocol message to the Ethernet tributary card 121, the second EFM extended protocol message carries the MAC address, device serial number, supplier name and fault information of the fiber optic transceiver 11, and the fault information is one of the following: optical port missing, power off. In response to the second EFM extended protocol message, the Ethernet tributary card 121 encapsulates the MAC address, device serial number, supplier name and fault information of the fiber optic transceiver 11 into a fourth message and sends it to the main control card 122. In response to the fault information in the fourth message, the main control card 122 deletes the information of the fiber optic transceiver 11 in the database. The main control card 122 sends an offline notification of the fiber optic transceiver 11 to the network management device 13 based on the management channel, so as to promptly notify the network management device 13 of the offline information of the fiber optic transceiver 11. In response to the offline notification of the optical fiber transceiver 11 , the network management device 13 deletes the information of the optical fiber transceiver 11 in the database, and updates the status information of the optical fiber transceiver 11 in a timely manner.

[0061] Exemplarily, the second EFM extended protocol message is an information OAMPDU message, and the fault information of the optical fiber transceiver 11 is transmitted by the Flags field in the information OAMPDU message. When the Flags field is 0, it indicates that the optical port of the optical fiber transceiver 11 is missing, when the Flags field is 1, it indicates that the optical fiber transceiver 11 is powered off, and when the Flags field is 2, it indicates that the electrical port link of the optical fiber transceiver 11 is disconnected. Exemplarily, if the electrical port link of the optical fiber transceiver 11 is disconnected, the main control card 122 updates the electrical port status information of the optical fiber transceiver 11 and notifies the network management device 13, and the network management device 13 then updates the electrical port status information.

[0062] In a specific embodiment, Figure 6As shown, the optical fiber transceiver 11 includes a first CPU 111 and a first Ethernet processing module 112. The first CPU 111 detects and obtains the first state information of the optical fiber transceiver 11, generates and sends a fifth message to the first Ethernet processing module 112, wherein the fifth message carries a first message label field, a first port number field and a first EFM extended protocol message, and the first port number corresponds to the port number of the electrical port or the port number of the optical port. The first message label field is used to indicate whether the message is an EFM message. The first Ethernet processing module 112 parses the first message label field, strips the first message label field and the first port number field, determines the port to which the corresponding message is sent based on the first port number field, and sends the first EFM extended protocol message to the Ethernet tributary board 121. Exemplarily, the first CPU 111 and the first Ethernet processing module 112 are interconnected through a GE port. In this embodiment, the fifth message sent between the first CPU 111 and the first Ethernet processing module 112 is used to identify that the message is an EFM message by adding the first message label field. For example, the first message tag field may be 0x818D. The first port number field in the message determines the outgoing port number to which the message needs to be sent. The port for EFM communication between the fiber optic transceiver 11 and the Ethernet tributary board 121 may be an optical port or an electrical port. Therefore, the port to which the message needs to be sent may be determined by the first port number field.

[0063] In a specific embodiment, Figure 6 As shown, the Ethernet tributary board 121 includes a second Ethernet processing module 1211 and a second CPU 1212. The second Ethernet processing module 1211 receives the first EFM extended protocol message sent by the optical fiber transceiver 11, encapsulates the first EFM extended protocol message, the second message label field, and the second port number field into a sixth message and sends it to the second CPU 1212. The second message label field is used to indicate whether the message is an EFM message. The second CPU 1212 receives the sixth message, determines that the sixth message is an EFM message based on the second message label field and parses it, obtains the first state information of the optical fiber transceiver 11 in the first EFM extended protocol message, and stores the first state information of the optical fiber transceiver 11 in the database. The second CPU 1212 encapsulates the first state information of the optical fiber transceiver 11 into a first message and sends it to the main control card 122. For example, the second message label field can be 0x818D. The second port number field is used to indicate the port for receiving the first EFM extended protocol message. The first Ethernet processing module 1211 is connected to multiple fiber optic transceivers through multiple external ports. A mapping relationship can be established between each fiber optic transceiver based on the port number of each port. Therefore, the port for receiving the message can be determined based on the second port number field.

[0064] In a specific embodiment, Figure 6As shown, the main control card 122 includes a switching module 1221 and a third CPU 1222.
