FIG. 3 is a schematic diagram of a topology networking identification process of a wavelength division device according to an embodiment of the present application, and the process includes:

S301: The network device acquires transmission distances corresponding to multiple radio frequency units.

The transmission distance is the transmission distance from the radio frequency unit to the BBU port connected to the radio frequency unit. The network device can acquire the connection relationship between the radio frequency unit and the BBU port (port) after the radio frequency unit and the BBU are powered on for communication. Referring to the connection relationship between the radio frequency unit and the BBU port shown in Figure 4, Table 1 shows the connection relationship between the radio frequency unit and the BBU port in the network equipment, the radio frequency unit 1 is connected with the BBU port 0, the radio frequency unit 2 is connected with the BBU port 1, ...

Table 1

For determining the transmission distance corresponding to the radio frequency unit, the network device can obtain the one-way delay between the radio frequency unit and the BBU port connected to the radio frequency unit, according to the one-way delay between the radio frequency unit and the BBU port connected to the radio frequency unit and the optical The transmission speed of the signal determines the corresponding transmission distance of the radio frequency unit. Among them, to obtain the one-way delay between the radio frequency unit and the BBU connected to the radio frequency unit, the time stamp delay measurement method, the 1588 delay measurement method, and the high precision in the Internet Protocol Performance Metrics (IPPM) protocol can be used. One-way delay measurement method, etc. to determine.

As an example, the radio frequency unit may add a time stamp t1 for sending the test packet to the test packet sent to the BBU port connected to the radio frequency unit. When the BBU port receives the test packet sent by the radio frequency unit, the test packet The time stamp t2 of the received test packet is marked on it, and according to the time difference recorded between the time stamp t2 and the time stamp t1, the one-way delay between the radio frequency unit and the BBU port connected to the radio frequency unit can be obtained. According to the connection between the radio frequency unit and the radio frequency unit The product of the one-way delay between the BBU ports and the transmission speed of the optical signal in the optical fiber (such as km/5us) can obtain the transmission distance corresponding to the radio frequency unit.

In addition, the wavelength division equipment used in the network equipment will regulate the wavelength of the optical module of the radio frequency unit and the BBU port. Different wavelength division equipment has different specifications for the wavelength of the optical module of the radio frequency unit and the BBU port. The wavelength division equipment is 6 wavelengths. Take the CWDM wavelength division equipment as an example, according to the wavelength specification of the 6-wave CWDM wavelength division equipment for the optical module, the wavelength of the optical module of the radio frequency unit can be 1271 or 1291 or 1311 (unit: nanometer (nm)), and the wavelength of the optical module of the BBU port can be It is 1331 or 1351 or 1371 (unit: nanometer).

If the wavelength of the optical module of the RF unit and/or the wavelength of the optical module of the BBU port connected to the RF unit does not meet the wavelength specification of the optical module of the wavelength division device, it can be determined that the RF unit does not belong to any wavelength division device group, and the wavelength division device is not connected. The network device may exclude the transmission distance corresponding to the radio frequency unit, and not determine the wavelength division device group for the radio frequency unit. For example: Assuming that the wavelength of an optical module of a radio frequency unit is 1330, and the CWDM wavelength division equipment that does not belong to 6 waves has a wavelength specification of 1271 or 1291 or 1311 for the optical module, the transmission distance corresponding to the radio frequency unit will be excluded, and the radio frequency unit will not be waved.

As an example: the network device may also acquire multiple radio frequency units in the network device and multiple radio frequency units connected to multiple radio frequency units before acquiring the transmission distances corresponding to the multiple radio frequency units or after acquiring the transmission distances corresponding to the multiple radio frequency units. The wavelength of the optical module of the BBU port, the specific acquired wavelengths of the optical modules of the multiple radio frequency units and the acquired wavelengths of the optical modules of the multiple BBU ports connected to the multiple radio frequency units can be shown in Table 2 and Table 3 below. After acquiring the transmission distances corresponding to multiple radio frequency units, the network device can determine whether the wavelength of the optical module of the radio frequency unit and/or the wavelength of the optical module of the BBU port connected to the radio frequency unit conforms to the wavelength specification of the optical module. If the wavelength of the module and/or the wavelength of the optical module of the BBU port connected to the radio frequency unit does not conform to the wavelength specification of the optical module, the transmission distance corresponding to the radio frequency unit is excluded, and the radio frequency unit is not grouped for identification.

S302: The network device divides the multiple radio frequency units into one or more wavelength division equipment groups according to the transmission distances corresponding to the multiple radio frequency units.

Wherein, the difference between the transmission distances corresponding to any two radio frequency units in each wavelength division equipment group is not greater than the distance difference threshold.

For RF units that use the same wavelength division device for fiber multiplexing, the connected main fiber (the fiber between the wavelength division device on the RF unit side and the wavelength division device on the BBU side) is the same, the length of the main fiber is the same, only on the RF unit side There may be slight differences in the pigtail lengths between the WDM equipment and each RF unit. Therefore, the transmission distance between each RF unit connected to the same WDM device and the BBU port connected to the RF unit is similar. In this embodiment of the present application, the radio frequency units may be grouped by wavelength division devices according to whether the difference between the transmission distances corresponding to the two radio frequency units is not greater than the set distance difference.

In a possible implementation, the network device may sort the transmission distances corresponding to the multiple radio frequency units from small to large or from large to small to obtain a transmission distance sequence; then traverse the transmission distance sequence, when the traversed current transmission distance is equal to When the difference between the current transmission distance and the next transmission distance is greater than the distance difference threshold, a grouping identifier is added between the current transmission distance and the next transmission distance of the current transmission distance, the transmission distance is grouped, and then the radio frequency unit is grouped according to the transmission distance. Perform WDM device group identification.

Table 4

Taking the transmission distance corresponding to the radio frequency unit in Table 4 as an example, assuming that the distance difference threshold is 0.3 (unit: kilometers (km)), the network device sorts the transmission distances corresponding to radio frequency unit 1 to radio frequency unit 6 in descending order, The transmission distance sequences 10.3, 10.2 (corresponding to radio frequency unit 1), 10.2 (corresponding to radio frequency unit 3), 8.4, 8.2 (corresponding to radio frequency unit 4), and 8.2 (corresponding to radio frequency unit 6) are obtained. The network equipment starts to traverse from 10.3, the difference between 10.3 and 10.2 is not greater than 0.3, the network equipment continues to judge whether the difference between 10.2 and 10.2 is not greater than 0.3; the difference between 10.2 and 10.2 is not greater than 0.3, the network equipment continues to judge whether the difference between 10.2 and 8.4 is not greater than greater than 0.3; the difference between 10.2 and 8.4 is greater than 0.3, and the network device adds a group identifier between 10.2 and 8.4; the network device continues to judge whether the difference between 8.4 and 8.2 is not greater than 0.3; the difference between 8.4 and 8.2 is not greater than 0.3, and the network device continues to judge Whether the difference between 8.2 and 8.2 is not greater than 0.3; the difference between 8.2 and 8.2 is not greater than 0.3, and the traversal ends. The transmission distances in the transmission distance sequence are divided into two groups by the group identifier, namely, transmission distance group 1, including: 10.3, 10.2, and 10.2, and transmission distance group 2, including 8.4, 8.2, and 8.2.

In transmission distance group 1, 10.3, 10.2 and 10.2 correspond to radio frequency unit 2, radio frequency unit 1 and radio frequency unit 3 respectively. In transmission distance group 2, 8.4, 8.2 and 8.2 correspond to radio frequency unit 5, radio frequency unit 4 and radio frequency unit 6 respectively. Network equipment It can be determined that the radio frequency unit 2, the radio frequency unit 1 and the radio frequency unit 3 belong to a wavelength division equipment group, and the radio frequency unit 5, the radio frequency unit 4 and the radio frequency unit 6 belong to a wavelength division equipment group. As shown in FIG. 5 , it is the result of identifying the topology networking of the wavelength division equipment in the network equipment.

In another possible implementation, the network device may also be based on the principle that the wavelengths of the optical modules of any two radio frequency units in the wavelength division equipment group are different, and the difference between the transmission distances corresponding to any two radio frequency units is not greater than the distance difference threshold, Group multiple RF units into one or more WDM equipment groups.

Still take the optical module wavelength of the radio frequency unit in Table 2 and the transmission distance corresponding to the radio frequency unit in Table 4 as an example, assuming that the distance difference threshold is 0.3 (unit: km) as an example: as shown in Table 5 and Table 6, The network device can arrange the transmission distances corresponding to the radio frequency units under the wavelengths of each optical module in descending order, and extract the maximum transmission distances (10.2, 10.3, and 10.2 in the example) under the wavelengths of each optical module. In the transmission distance, select the minimum transmission distance (10.2 in the example) and the transmission distance whose difference from the selected minimum transmission distance is not greater than the distance difference threshold (10.3 and 10.2 in the example), and divide them into a transmission distance group. The transmission distance added to the transmission distance group is deleted from the transmission distance under the wavelength of each optical module.

The network equipment repeatedly extracts the maximum transmission distance under the wavelength of each optical module, selects the minimum transmission distance from the extracted transmission distance and the transmission distance whose difference from the selected minimum transmission distance is not greater than the distance difference threshold, and divides it into a transmission distance. The process of deleting the transmission distance added to the transmission distance group in the transmission distance under each optical module wavelength, until the transmission distance under each optical module wavelength has been added to the transmission distance group. The network device gets another transmission distance group (8.2, 8.4 and 8.2).

The transmission distance groups obtained by the network equipment are shown in Table 6, in which 10.2, 10.3 and 10.2 in transmission distance group 1 correspond to RF unit 1, RF unit 2 and RF unit 3 respectively, and 8.2, 8.4 and 8.2 in transmission distance group 2 correspond respectively Radio frequency unit 4, radio frequency unit 5 and radio frequency unit 6, the network device determines that radio frequency unit 1, radio frequency unit 2 and radio frequency unit 3 belong to a wavelength division equipment group, and radio frequency unit 4, radio frequency unit 5 and radio frequency unit 6 belong to a wavelength division equipment group .

The radio frequency unit 2 and the radio frequency unit 3 are in a wavelength division equipment group, and the radio frequency unit 1, the radio frequency unit 2 and the radio frequency unit 3 share (or multiplex) an optical fiber through the same wavelength division equipment.

In addition, in the case where there are multiple types of wavelength division devices in the network device, the network device can also determine the wavelengths of the multiple radio frequency units according to the wavelength specifications of the optical modules of the multiple types of wavelength division devices and the wavelengths of the optical modules of the multiple radio frequency units.
