The embodiment of the invention provides a method for determining a topological relation of wavelength division equipment, a control system, the wavelength division equipment and a storage medium. The method for determining the topological relation of the wavelength division equipment can be applied to a mobile terminal or a server, and the mobile terminal can be an electronic device such as a mobile phone, a tablet computer, a notebook computer, a desktop computer, a personal digital assistant and a wearable device.
Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for determining a topological relation of a wavelength division device according to an embodiment of the present invention.
As shown in fig. 1, the method for determining the topological relation of the wavelength division device includes step S101.
Step S101, receiving a first composite message sent by a first wavelength division device and a second composite message sent by a second wavelength division device, and determining a topological relation between the first wavelength division device and the second wavelength division device according to the first composite message and the second composite message.
The first synthesized message is a message obtained by synthesizing a message of the first wavelength division device with a message of the second wavelength division device received through the first optical interface, and the second synthesized message is a message obtained by synthesizing a message of the second wavelength division device with a message of the first wavelength division device received through the second optical interface.
The first wavelength division device sends the first synthesis message to the control system, and the second wavelength division device sends the second synthesis message to the control system, so that the control system can determine the topological relation between the first wavelength division device and the second wavelength division device according to the first synthesis message and the second synthesis message after receiving the first synthesis message and the second synthesis message. In some embodiments, a topological relationship between the first wavelength division device and the second wavelength division device is determined, that is, whether the optical fiber link between the first wavelength division device and the second wavelength division device is a bi-directionally connected link is determined.
Since the first wavelength division device and the second wavelength division device can obtain the first synthesized message and the second synthesized message only by performing message interaction, in some embodiments, the messages of the first wavelength division device and the second wavelength division device are g.metro TOM messages. The method comprises the following steps: and configuring the TOM message based on the top modulation technology, the amplitude modulation technology or the frequency division technology of the optical signal to obtain messages of the first wavelength division equipment and the second wavelength division equipment.
And configuring the TOM message based on a top modulation technology, an amplitude modulation technology or a frequency division technology of the optical signal, so that the first wavelength division equipment and the second wavelength division equipment can perform message interaction in the form of the TOM message at an optical layer.
Taking the frequency division technique as an example, the steps when configuring the TOM message may be specifically as follows:
1. the TEE transmitter is turned off and enters a standby mode.
2. The TEE transmitter is turned off but ready to begin entering the conditioning phase.
3. The TEE transmitter scans the adjustment frequency to transmit at the required adjustment power to transmit the pilot at the modulation depth at the time of adjustment.
4. The TEE transmitter operates in the required channel, transmits the pilot at the modulation depth in the normal operating mode, and adjusts the output optical power and center frequency.
5. The TEE operates at the required optical power and center frequency, transmits the pilot at the modulation depth in the normal operation mode, and transmits the traffic (i.e., normal operation mode).
6. The TEE operates at the required optical power and center frequency, transmits THMC, and transmits traffic (i.e., normal operating mode).
After the above steps are completed, the configuration of the TOM message may be completed, that is, the first wavelength division device and the second wavelength division device may perform message interaction at the optical layer by using the TOM message.
In some embodiments, obtaining the messages of the first wavelength division device and the second wavelength division device includes: and determining the TOM value of the TOM message, and writing the connection information of the first wavelength division equipment and the connection information of the second wavelength division equipment into the TOM message to obtain messages of the first wavelength division equipment and the second wavelength division equipment.
The connection information of the first wavelength division device comprises information such as a local IP address, a local TCP-ID, a proxy network ID and a proxy network address of the first wavelength division device. Similarly, the connection information of the second wavelength division device includes information such as a local IP address, a local TCP-ID, a proxy network ID, and a proxy network address of the second wavelength division device.
Because different TOM values in the TOM message represent different message types and message contents, after the TOM value in the TOM message is determined, the connection information of the first wavelength division device and the connection information of the second wavelength division device can be written into the two TOM messages respectively, so that the message of the first wavelength division device and the message of the second wavelength division device are obtained.
For example, the correspondence of TOM values to message types and message contents may be as shown in the following table:
| TOM value | Message | Message content | |
| 0 | Free up | ||
| 1 | Frequency of | |
|
| 2 | Optical power at the time of adjustment | Optical power setting value upon |
|
| 3 | Pilot frequency | Pilot frequency for TEE to HEE to use as |
|
| 4 | Start-up scanning (Regulation) | ||
| 5 | Close off | ||
| 6 | Stop scan (adjustment) | ||
| 7 | Varying optical power | Novel |
|
| 8 | Varying frequency | |
|
| 9 | Sending traffic flows | ||
| 10 | Transmitting pilot | ||
| 11 | Ceasing transmission of pilots | ||
| 12-1023 | System reservation | ||
| 1024-4027 | Other private messages |
In some embodiments, the interaction of the messages between the first wavelength division device and the second wavelength division device may be performed by changing a TOM value in the TOM message and selecting a different TOM message type. For example, the TOM value may be determined to be 9, that is, the message type of the service traffic is selected to perform the interaction of the message between the first wavelength division device and the second wavelength division device, or the TOM value may be determined to be a value between 1024 and 4027 (including 1024 and 4027), that is, the message type of the private message is selected to perform the interaction of the message between the first wavelength division device and the second wavelength division device.
After the message type of the TOM message is determined, the connection information of the first wavelength division device may be written into the TOM message of which the message type has been determined, so as to obtain the message of the first wavelength division device, and similarly, the connection information of the second wavelength division device may be written into the TOM message of which the message type has been determined, so as to obtain the message of the second wavelength division device.
The formats of the obtained message of the first wavelength division device and the message of the second wavelength division device are shown in fig. 2a and fig. 2b, where fig. 2a is a schematic diagram of the message format, and fig. 2b is a detailed schematic diagram of the message format. The Format ID and the Arabic numbers above the Format specific data represent bit positions, the Format ID represents Format identification codes and is used for representing IDs of different messages, and the Format specific data represents Format specific data and is used for representing detailed contents in the messages.
As shown in FIG. 2b, the Format specific data further includes DA DCN context ID, DA DCN context ID cont'd, DA DCN address cont'd, and Local TCP-ID, respectively. The DA DCN context ID is a Discovery Agent Data Communication Network ID, namely represents a proxy Network ID, takes up 16 bits, and can be reserved to be filled with 0 when being filled, the DA DCN context ID cont'd is a Discovery Agent Data Communication Network ID connected, so that more proxy Network IDs are represented, the DA DCN address represents a proxy Network address and takes up 32 bits, a wavelength division equipment management IPv4 address can be filled in when being filled, the DA DCN address cont'd represents more proxy Network addresses, the Local TCP ID represents a Local TCP-ID and takes up 32 bits, and a sub-frame, a slot position, a sub-card and a port number of the wavelength division equipment can be respectively filled in when being filled, wherein the sub-frame, the slot position, the sub-card and the port number respectively take up 8 bits.
After the message content is filled according to the format to obtain the message of the first wavelength division device and the message of the second wavelength division device, the first wavelength division device and the second wavelength division device can perform message interaction to obtain a first synthesized message and a second synthesized message.
It should be noted that the first synthesized message and the second synthesized message may be written into the TOM message, and the first wavelength division device and the second wavelength division device may directly send the first synthesized message and the second synthesized message to the control system at the optical layer in the form of the TOM message, or may not write the TOM message, and the first wavelength division device and the second wavelength division device send the first synthesized message and the second synthesized message to the control system in other manners.
The second wavelength division equipment sends the message to the first wavelength division equipment, and after receiving the message sent by the second wavelength division equipment, the first wavelength division equipment synthesizes the message with the message of the second wavelength division equipment to obtain a first synthesized message and sends the first synthesized message to the control system; and the first wavelength division device sends the message of the first wavelength division device to the second wavelength division device, and the second wavelength division device synthesizes the message of the first wavelength division device with the message of the second wavelength division device after receiving the message of the first wavelength division device to obtain a second synthesized message and sends the second synthesized message to the control system, so that the control system can determine the topological relation between the first wavelength division device and the second wavelength division device according to the first synthesized message and the second synthesized message.
In some embodiments, determining the topological relationship of the first wavelength division device and the second wavelength division device from the first composite message and the second composite message comprises: determining whether the first composite message and the second composite message are the same; and if the first synthetic message is the same as the second synthetic message, determining that the topological relation of the first wavelength division equipment and the second wavelength division equipment is a bidirectional connection relation.
After receiving a first synthesized message sent by a first wavelength division device and a second synthesized message sent by a second wavelength division device, a control system can judge whether the first synthesized message and the second synthesized message are the same, if the first synthesized message and the second synthesized message are the same, the first wavelength division device and the second wavelength division device are considered to be in bidirectional direct communication, a bidirectional optical fiber link is formed between the first wavelength division device and the second wavelength division device, and the topological relation between the first wavelength division device and the second wavelength division device is determined to be a bidirectional connection relation.
In some embodiments, since the message of the first wavelength division device includes the connection information of the first wavelength division device, the message of the second wavelength division device includes the connection information of the second wavelength division device. Thus, determining whether the first composite message and the second composite message are the same comprises: determining whether the connection information of the first wavelength division device in the first composite message and the connection information of the first wavelength division device in the second composite message are the same, and whether the connection information of the second wavelength division device in the first composite message and the connection information of the second wavelength division device in the second composite message are the same; and if the connection information of the first wavelength division device in the first composite message is the same as the connection information of the first wavelength division device in the second composite message, and the connection information of the second wavelength division device in the first composite message is the same as the connection information of the second wavelength division device in the second composite message, determining that the first composite message is the same as the second composite message.

If the connection information of the first wavelength division device in the first composite message is the same as the connection information of the first wavelength division device in the second composite message, and the connection information of the second wavelength division device in the first composite message is also the same as the connection information of the second wavelength division device in the second composite message, the first composite message and the second composite message are considered to be the same.
If the connection information of the first wavelength division device in the first composite message is different from the connection information of the first wavelength division device in the second composite message, or the connection information of the second wavelength division device in the first composite message is different from the connection information of the second wavelength division device in the second composite message, or the connection information of the first wavelength division device in the first composite message is different from the connection information of the first wavelength division device in the second composite message, and the connection information of the second wavelength division device in the first composite message is different from the connection information of the second wavelength division device in the second composite message, the first composite message is considered to be different from the second composite message.
After the first synthetic message and the second synthetic message are determined to be the same, the topological relation between the first wavelength division device and the second wavelength division device can be determined to be a bidirectional connection relation, and the determination of the topological relation between the first wavelength division device and the second wavelength division device is completed.

After receiving a message of a second wavelength division device sent by a second wavelength division device, the first wavelength division device synthesizes the message of the first wavelength division device with the message of the second wavelength division device to obtain first synthesis information, and sends the first synthesis information to the control system. The localipadd and localTCP-ID represent messages of the first wavelength division device, and the peerpadd and peerTCP-ID represent messages of the second wavelength division device.
Similarly, after receiving the message of the first wavelength division device sent by the first wavelength division device, the second wavelength division device synthesizes the message of the second wavelength division device with the message of the first wavelength division device to obtain second synthesis information, and sends the second synthesis information to the control system. The localipadd and localTCP-ID represent messages of the second wavelength division device, and the peerpadd and peerTCP-ID represent messages of the first wavelength division device.
And the control system compares whether the first synthesis information and the second synthesis information are the same or not after receiving the first synthesis information and the second synthesis information, and forms a bidirectional optical fiber link between the first wavelength division equipment and the second wavelength division equipment when the first synthesis information and the second synthesis information are the same.
