Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The advent of the 5G era and the explosive growth of services such as video, games, and intelligent terminals have led to a rapid rise in traffic flow, with the consequent unavoidable acceleration and expansion of optical network systems. In order to ensure the reliability and stability of the optical network system, daily operation and maintenance management work is required. The operation and maintenance management of the optical network system includes management of resources of the optical network system, such as allocation and dynamic adjustment of the resources of the optical network system.
An optical network system includes a plurality of communication devices. Each communication device comprises optical transmission means. The optical transmission devices in the two communication devices are connected through an optical fiber link so as to realize communication between the two communication devices. The optical transmission device in the current communication equipment can monitor whether the working state of the optical transmission device is abnormal or not, and give an alarm when the working state of the optical transmission device is abnormal. However, if an optical transmission device is connected with a fiber in the process of allocating or adjusting the resources of the optical network system, the current optical transmission device cannot sense which optical transmission device is connected with the other end of the optical fiber link, so that an operator is difficult to locate the error root cause, which causes a higher management difficulty of the optical network system and lower adjustment efficiency of the resources of the optical network system. The optical transmission device is connected with another optical transmission device which should originally establish a communication connection relationship by an optical fiber link, so that communication between the two optical transmission devices is impossible, or the optical transmission device is connected with another optical transmission device which should not originally establish a communication connection relationship by an optical fiber link, so that unreasonable or illegal communication between the two optical transmission devices is caused, or a unidirectional communication connection relationship in a direction from the optical transmission device to the other optical transmission device should be established between the optical transmission device and the other optical transmission device, but a unidirectional communication connection relationship in a direction from the other optical transmission device to the optical transmission device is established due to optical fiber receiving and reversing connection, and the like.
Based on this, the embodiment of the application proposes a technical solution, where the sending side communication device sends a message including the identifier of the optical transmission device through the optical transmission device, and after the optical transmission device in the receiving side communication device receives the message, the receiving side communication device can determine that the optical transmission device that receives the message has a communication connection relationship with the optical transmission device indicated by the identifier carried in the message in the transmission direction of the message. In the embodiment of the application, the communication equipment can clearly determine the communication connection relationship in the specific direction between the optical transmission device of the communication equipment and other optical transmission devices, so that an operation and maintenance person can know the fiber connection relationship between the optical transmission devices in the optical network system, and the distribution and adjustment efficiency of resources of the optical network system can be improved.
On the basis, after the receiving-side communication device receives the message carrying the identifier of the optical transmission device, the receiving-side communication device may further send, in response to the message, another message including the identifier of the optical transmission device that received the message and the identifier of the optical transmission device carried in the message through the optical transmission device that received the message, so as to determine whether the optical transmission device that received the message and the optical transmission device indicated by the identifier carried in the message have a communication connection relationship in a direction opposite to the transmission direction of the message. When the transmitting-side communication device receives the other message, the transmitting-side communication device can determine that two optical transmission devices respectively indicated by two identifiers carried in the other message have a bidirectional communication connection relationship according to the other message.

The transmitter of the second optical transmission apparatus 021 is for transmitting an optical signal to the receiver of the first optical transmission apparatus 011 through the optical fiber 032, and the receiver of the second optical transmission apparatus 021 is for receiving an optical signal transmitted from the transmitter of the first optical transmission apparatus 011 through the optical fiber 031. Alternatively, the transmitter of the first optical transmission device 011 and the receiver of the second optical transmission device 021 and the receiver of the first optical transmission device 011 and the transmitter of the second optical transmission device 021 are connected by the same optical fiber. The embodiments of the present application are not limited in this regard.
With continued reference to fig. 1, the optical transmission apparatus further includes a supplemental channel modulation unit and a supplemental channel demodulation unit. The auxiliary channel modulating unit is used for modulating non-service signals such as management information, control information, physical characteristic parameters and the like except the service signals, and correspondingly, the auxiliary channel demodulating unit is used for demodulating the non-service signals. An auxiliary channel may be implemented based on the auxiliary channel modulation unit in the first optical transmission apparatus 011 and the auxiliary channel demodulation unit in the second optical transmission apparatus 021, for the first optical transmission apparatus 011 to transmit the non-traffic signal to the second optical transmission apparatus 021. Similarly, another auxiliary channel may be implemented based on the auxiliary channel modulation unit in the second optical transmission apparatus 021 and the auxiliary channel demodulation unit in the first optical transmission apparatus 011, for the second optical transmission apparatus 021 to transmit the non-traffic signal to the first optical transmission apparatus 011. The supplemental channel modulation unit and the supplemental channel demodulation unit in one optical transmission apparatus may be the same unit (referred to as a supplemental channel modulation/demodulation unit) or may be different units.
Optionally, the auxiliary channel between the two optical transmission devices is implemented based on an optical fiber link connecting the two optical transmission devices. For example, in the optical network system shown in fig. 1, an auxiliary channel between the first optical transmission device 011 and the second optical transmission device 012 is realized based on the optical fiber link 03. That is, the supplemental channel and the traffic channel may share the same physical link. In this embodiment of the present application, the auxiliary channel between two optical transmission apparatuses may be any communication channel capable of transmitting a non-traffic signal between two communication devices. For example, the message 1, the message 2, the first message, the second message, the third message, and the fourth message mentioned in the following embodiments of the present application are all non-service signals.
Alternatively, the auxiliary channel modulation/demodulation unit may implement the auxiliary channel by using a modulation and demodulation technique, for example, may implement the auxiliary channel by using a Light Sensor (LS) modulation and demodulation technique, where specific modulation modes include amplitude modulation/amplitude demodulation, phase modulation/phase demodulation, and so on. For example, the supplemental channel modulation unit may employ a modulated top technique to modulate the non-traffic signal onto the traffic signal for transmission, i.e., modulate the non-traffic signal into a modulated top signal. Accordingly, the auxiliary channel demodulation unit demodulates the received modulated top signal to obtain a non-service signal. In this implementation, the non-traffic signal and the traffic signal coexist during transmission.
Alternatively, the supplemental channel modulation/demodulation unit may implement the supplemental channel using a frame insertion technique, for example, a forward error correction (forward error correction, FEC) frame insertion method may be used to implement the supplemental channel. For example, the supplemental channel modulation unit may use a frame insertion technique to insert the non-traffic signal into the idle frame bytes of the traffic signal for transmission. Accordingly, the auxiliary channel demodulation unit extracts corresponding bytes in the received signal and demodulates the corresponding bytes to obtain the non-service signal. In this implementation, the non-service signal and the service signal do not interfere with each other in the transmission process. Alternatively, the supplemental channel modulation unit may use a frame insertion technique to insert the non-traffic signal into the reserved field of the training sequence frame for transmission. Accordingly, the auxiliary channel demodulation unit demodulates the reserved field of the received training sequence frame to obtain the non-service signal. Wherein the training sequence frames are typically transmitted prior to traffic signal transmission.
Alternatively, the auxiliary channel modulation/demodulation unit may be a separate modulation/demodulation unit, or may be integrated with a modulation/demodulation unit corresponding to the service signal, which is not limited in the embodiment of the present application.
In the embodiment of the application, besides the auxiliary channels implemented between the optical transmission devices, the auxiliary channels are implemented between the internal units of the optical transmission devices, between the optical transmission devices and the network equipment, and between the network equipment and the management equipment, and other data besides service data can be transferred through the auxiliary channels.
Optionally, the communication device further comprises a processing unit. Alternatively, the processing unit may be deployed in an optical transmission device, see for example fig. 1. Alternatively, the processing unit may be deployed in a network device. The processing unit is configured to perform processing operations such as determining whether the local optical transmission device has a communication connection relationship and a connection direction with an optical transmission device in other communication equipment, and so on. In addition, the processing unit can also control the reporting or issuing of instructions and the like.
Alternatively, the processing unit may be integrated with a digital signal processor (digital signal processor, DSP) or a microcontroller unit (microcontroller unit, MCU) (not shown in fig. 1), or may be a separate unit. The processing unit in the communication device is not necessary. For example, in some application scenarios, the communication device does not need to use a processing unit to process and analyze the acquired message, but directly reports the acquired message to the management device, and in such application scenarios, the processing unit does not need to be deployed in the communication device.
Optionally, referring to fig. 1, the optical network system further includes a management device 04. The management device 04 is used for managing and controlling network devices. Referring to fig. 1 for example, the first network device 012 and the second network device 022 are connected to the management device 04, respectively. Alternatively, the management device 04 is a server, or a server cluster formed by a plurality of servers, or a cloud platform.
The embodiment of the application provides a method for acquiring information of an optical network system, which can be applied to the optical network system shown in fig. 1. Fig. 3 is a flowchart of a method for obtaining information of an optical network system according to an embodiment of the present application. As shown in fig. 3, the method includes:
step 301, the communication device 1 sends a message 1 via the optical transmission apparatus 1, the message 1 comprising an identification of the optical transmission apparatus 1.
The optical transmission device 1 is an optical transmission device in the communication apparatus 1. The identity of the optical transmission device 1 in the message 1 is used to indicate that the message 1 is sent out by the optical transmission device 1.
Optionally, the identification of the optical transmission device comprises location information of the optical transmission device in the optical network system. The communication device 1 includes a network device 1, and after the network device 1 senses the insertion position of the optical transmission apparatus 1, the location information of the optical transmission apparatus 1 may be transmitted to the optical transmission apparatus 1 through the bus to be used as an identification of the optical transmission apparatus 1. The location information includes a location identifier of the optical transmission device on the board, a location identifier of the board on the network device, and an identifier of the network device. The position identifier of the optical transmission device on the single board may be a port number of a port into which the optical transmission device is inserted on the single board. The location identifier of the board on the network device may be a slot number of a slot into which the board is inserted on the network device. The identification of the network device may be information such as a media access control (media access control, MAC) address, an internet protocol (Internet Protocol, IP) address, or a device serial number of the network device that can uniquely identify the network device in the optical network system.
For example, if the communication device 1 is a communication device as shown in fig. 2 and the optical transmission apparatus 1 is an optical module B1, the location information of the optical transmission apparatus 1 in the optical network system may be represented as "network device a, master slot a1, and board port m1". Wherein, the "single board port m1" is the position identification of the optical transmission device on the single board, the "master control board slot a1" is the position identification of the single board where the optical transmission device is located on the network device, and the "network device a" is the identification of the network device where the single board where the optical transmission device is located. The position information indicates that the optical transmission apparatus 1 (optical module B2) is in the port m1 of the board in the slot a1 of the main control board on the network device a.
Step 302, after the communication device 2 receives the message 1 through the optical transmission apparatus 2, it determines, according to the message 1, a communication connection relationship between the optical transmission apparatus 1 and the optical transmission apparatus 2 having a direction 1, where the direction 1 is a direction from the optical transmission apparatus 1 to the optical transmission apparatus 2.
The optical transmission device 2 is an optical transmission device in the communication apparatus 2. After receiving the message 1, the communication device 2 determines that the message 1 is sent by the optical transmission apparatus 1 according to the identifier of the optical transmission apparatus 1 carried in the message 1. Since the optical transmission apparatus 2 in the communication device 2 can receive the message transmitted by the optical transmission apparatus 1 in the communication device 1, the communication device 2 can determine the communication connection relationship having the direction 1 between the optical transmission apparatus 1 and the optical transmission apparatus 2.
In step 302, the communication device can determine that the optical transmission device and other optical transmission devices have a unidirectional communication connection relationship according to the received message from the other optical transmission devices, so that the operation and maintenance personnel can know the connection relationship between the optical transmission devices in the optical network system, which is helpful for improving the allocation and adjustment efficiency of the resources of the optical network system.
Optionally, after receiving message 1, communication device 2 may also perform the following step 303.
Step 303, the communication device 2 sends a message 2 via the optical transmission means 2, the message 2 comprising an identification of the optical transmission means 1 and an identification of the optical transmission means 2.
The message 2 is used to determine whether the optical transmission device 1 and the optical transmission device 2 also have a communication connection relationship of direction 2. The direction 2 is a direction from the optical transmission device 2 to the optical transmission device 1. The identity of the optical transmission device 2 in the message 2 is used to indicate that the message 2 is sent by the optical transmission device 2. The identifier of the optical transmission apparatus 2 in the message 2 is also used to indicate, together with the identifier of the optical transmission apparatus 1 in the message 2, that the optical transmission apparatus 2 has received the message sent by the optical transmission apparatus 1.
The communication device 2 comprises a network device 2, and after the network device 2 senses the insertion position of the optical transmission apparatus 2, the network device 2 may send the position information of the optical transmission apparatus 2 to the optical transmission apparatus 2 through the bus to be used as an identification of the optical transmission apparatus 2.
Step 304, when the communication device 1 receives the message 2 through the optical transmission apparatus 1, it is determined that the optical transmission apparatus 1 and the optical transmission apparatus 2 have a bidirectional communication connection relationship according to the message 2.
Since the optical transmission apparatus 1 in the communication device 1 can receive the message transmitted by the optical transmission apparatus 2 in the communication device 2, the communication device 1 can determine the communication connection relationship having the direction 2 between the optical transmission apparatus 1 and the optical transmission apparatus 2. In addition, since the identifier of the optical transmission apparatus 1 and the identifier of the optical transmission apparatus 2 in the message 2 can collectively indicate that the optical transmission apparatus 2 has received the message sent by the optical transmission apparatus 1, the communication device 1 can also determine that the optical transmission apparatus 1 and the optical transmission apparatus 2 have the communication connection relationship of the direction 1. In summary, the communication apparatus 1 can determine that the optical transmission device 1 and the optical transmission device 2 have a bi-directional communication connection relationship therebetween.
In step 304, the communication device can determine that the optical transmission device and other optical transmission devices have a bi-directional communication connection relationship according to the received message from the other optical transmission devices, so that the operation and maintenance personnel can know the connection relationship between the optical transmission devices in the optical network system, which is helpful for improving the allocation and adjustment efficiency of the resources of the optical network system.
Optionally, when the communication device receives a message from another optical transmission apparatus, where the message includes the identities of the two optical transmission apparatuses, and neither of the two optical transmission apparatuses is an optical transmission apparatus in the communication device, the communication device may determine that a fiber connection error occurs between the two optical transmission apparatuses, and issue an alarm to indicate that a fiber connection error occurs between the two optical transmission apparatuses. The operation staff can intervene manually to perform the fiber re-connection treatment.
In the network upgrading process, the cutting scene needs to cut lines in a large range, and the fiber connection verification function of the optical transmission device is applied in the scene, so that the fiber connection error positioning can be realized, and the cutting difficulty and cost can be reduced.
In the method shown in fig. 3, the communication device 1 is the initiator of the fibre attachment check and, correspondingly, the communication device 2 is the responder of the fibre attachment check.
In this embodiment of the present application, the communication connection relationship between the optical transmission device and the other optical transmission devices may be determined only by the responder of the fiber connection verification, and then the above steps 303 and 304 may not be performed. In the communication connection relationship determined by the responder of the connection verification, the connection direction is always the direction from the initiator of the connection verification to the responder of the connection verification, for example, the communication connection relationship determined by the communication device 2 in step 302. Alternatively, the communication connection relationship between the own optical transmission device and the other optical transmission device may be determined only by the initiator of the fiber connection verification, and the above step 302 may not be performed. The communication connection relationship determined by the initiator of the fiber connection verification is a bi-directional communication connection relationship, for example, the communication connection relationship determined by the communication device 1 in step 304. Alternatively, the communication connection relationship between the own optical transmission device and other optical transmission devices may be determined by the responder of the fiber connection verification and the initiator of the fiber connection verification, respectively.
Alternatively, the communication apparatus may further transmit connection information to the management apparatus to indicate the optical transmission device having the communication connection relationship after determining the communication connection relationship between the own optical transmission device and the other optical transmission device.
For example, the above-described communication apparatus 2 may, after determining that the optical transmission device 1 and the optical transmission device 2 have the communication connection relationship of the direction 1, transmit, to the management apparatus, connection information 1 including the identification of the optical transmission device 1, the identification of the optical transmission device 2, and the connection direction between the optical transmission device 1 and the optical transmission device 2, the connection direction including the direction 1. The connection information 1 is used to indicate a communication connection relationship between the optical transmission device 1 and the optical transmission device 2 having a direction 1.
For another example, after determining that the optical transmission device 1 and the optical transmission device 2 have a bidirectional communication connection relationship, the communication apparatus 1 may send connection information 2 to the management apparatus, where the connection information 2 includes an identification of the optical transmission device 1, an identification of the optical transmission device 2, and a connection direction between the optical transmission device 1 and the optical transmission device 2, and the connection direction indicates bidirectional connection. The connection information 2 is used to indicate that the optical transmission device 1 and the optical transmission device 2 have a bi-directional communication connection relationship.
In the embodiment of the application, the communication equipment reports the connection information about the optical transmission devices to the management equipment, so that the management equipment can generate and display the topology between the optical transmission devices, further the visualization of the fiber connection topology of the optical network system is realized, the operation and maintenance personnel can know the fiber connection relationship between the optical transmission devices in the optical network system, and the distribution and adjustment efficiency of resources of the optical network system are improved. In addition, the management device can also automatically schedule the service according to the fiber connection topology of the optical network system. For example, in the case of failure of one fiber link, the backup link can be identified to distribute the service to the sound backup link to ensure that the service can operate normally. And for example, under the condition that traffic congestion exists on the optical fiber link, the traffic scheduling optimization is realized in combination with traffic and traffic scheduling.

The communication device 1 may send the resource information of the network device 1 to the management device, and/or the communication device 2 may send the resource information of the network device 2 to the management device, so that the management device determines and displays the resource usage of the optical network system according to the resource information of the network device 1 and the connection information 1, and/or the resource information of the network device 2 and the connection information 2.
In the embodiment of the application, the communication device reports the resource information of the network device to the management device, so that the management device can determine and display the resource use condition of the optical network system according to the resource information of the network device and the connection information of the optical transmission device. The operation and maintenance personnel can intuitively check the idle resources of the network equipment so as to adjust the resources of the optical network system and realize the optimization of the networking structure of the optical network system. For example, according to the network equipment requirement, the idle port utilization of the network equipment can be easily realized, and the communication capacity is expanded. For another example, by network analysis, the communication connection between the station and the network device can be identified. For another example, according to the communication speed and capacity requirement, the high-speed module can be selectively used for replacing a plurality of low-speed modules, so that the module upgrading and capacity expansion can be realized.
