In order to stably transmit the service through the network, the design of a loop can be adopted for networking. When the network fails, data transmission traffic can be automatically recovered from other paths in the ring network in a short time.

Typically, networking design and cable laying are independent of each other. When the optical cable is laid in actual construction, the phenomenon that the loop and the channel are laid is easily generated, namely the optical cable sections originally used for looping are far away from each other in physical position, and the optical cable sections actually laid for looping are close to each other in physical position, even are laid at the same position.

However, it is often the case that a cable break causes a network failure, such as a cable being cut, and the network that should form the loop does not provide protection to the loop, thereby preventing the network from being quickly restored.

The method for determining a false loop provided by the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.

Fig. 1 is a schematic diagram of a network topology provided in an embodiment of the present disclosure. As shown in fig. 1 (a), a logical loop of a network includes: the 3 node devices are respectively device 1, device 2 and device 3, the 3 node devices form a logical loop, and when the device 1 sends data to the device 2, the data of the device 1 can be directly sent to the device 2, or sent to the device 2 through the device 3. As shown in fig. 1 (b), this is the case of the optical cable actually laid in the network. When the optical cable between the device 1 and the device 2 is cut, the device 1 and the device 2 cannot perform data transmission, and when the optical cable between the device 1 and the device 3 is cut, the device 1 and the device 3 cannot perform data transmission.

It should be noted that the method for determining a false loop provided in the embodiment of the present disclosure is mainly used for identifying which of the optical cables actually laid constitute a false loop similar to the case shown in (b) in fig. 1.

Fig. 2 is a schematic flowchart of a method for determining a false loop according to an embodiment of the present disclosure, as shown in fig. 2, the method includes the following steps S201 to S204:

s201, determining a logic loop of the communication network based on the logic topological graph of the communication network.

Wherein, the logical topology diagram of a communication network includes the connection relationship of every two devices.

For example, a logical topology may indicate: the node of the first device is connected with the node of the second device, the node of the first device is connected with the node of the third device, and the node of the second device is connected with the node of the third device.

The connection of two nodes in the logical topology graph can indicate that the two connected nodes can perform data transmission without forwarding through other nodes.

Exemplarily, fig. 3 is a logical topology diagram of a communication network provided in an embodiment of the present disclosure, as shown in fig. 3, the communication network includes 5 nodes, which are respectively: node 1, node 2, node 3, node 4, and node 5. Wherein, node 1 is connected with node 2, node 1 is connected with node 3, and node 2 is connected with node 3. The data of the node 1 can be directly sent to the node 2, or can be sent to the node 2 through the node 3. The logical transmission path between node 1 and node 2 may constitute a logical loop.

It should be noted that, in the embodiment of the present disclosure, the logical topology map may be traversed to determine each logical loop in the logical topology map.

S202, according to the unique device identifier and the port identifier of the device group, position information of a light path connected with the first device group in the first logic loop is obtained.

The first logical loop is any one logical loop in a communication network, and one equipment group comprises two end equipment for transmitting data.

It should be noted that, in the embodiment of the present disclosure, one device group is defined to correspond to one logical loop, and one logical loop may include at least two optical paths for transmitting data, one optical path for directly transmitting data between the device groups, and the other optical path for transmitting data from one end device of the device group to another end device through another node device.

In the embodiment of the present disclosure, the position information of the optical path connecting the device group in the logical loop of the device group may be determined according to the preset physical data query model, the unique identifier of the device group, and the port identifier.

Wherein the physical data query model comprises: optical fiber light path table, optical cable fiber core table and optical cable section table.

Illustratively, the fiber optical path table (Phy _ Opt _ Road) may include: the optical path ID, the optical path name, the unique identifier of the A-end port, the unique identifier of the A-end equipment, the unique identifier of the Z-end port and the unique identifier of the Z-end equipment. The optical cable core table (Phy _ Opt _ Pair) can comprise: light path ID, fiber core ID, optical cable section, fiber core group and cable sequence. The cable section table (Phy _ Opt _ Optical _ search) may include a cable section ID, a cable section name, a management area, the cable to which it belongs (foreign key: cable ID), cable a-end geographical coordinates, and cable Z-end geographical coordinates.

S203, judging whether two optical cable segments with the similarity of the position information larger than or equal to a preset threshold exist in different optical paths connected with the first equipment group.

It will be appreciated that the two cable lengths described above are cable lengths in different optical paths of the first device.

Wherein each of the two cable segments may be a cable segment in one or more optical paths.

For example, if it is determined that the positions of two cable segments in different optical paths in one device group are the same, or the distance between the positions of two cable segments in different optical paths in one device group is smaller than or equal to a preset distance, the similarity of the position information of the two cable segments is greater than or equal to a preset threshold. If the distance between the positions of the two optical cable segments in different optical paths in one equipment group is greater than the preset distance, the similarity of the position information of the two optical cable segments is smaller than the preset threshold.

Optionally, the preset threshold is set according to actual needs, and this is not specifically limited in the embodiments of the present disclosure.

And S204, if two optical cable segments with the position information similarity larger than a preset threshold exist, determining that a false loop exists in the physical loop corresponding to the first logic loop.

It can be understood that if the similarity of the position information of every two optical cable segments in different optical paths connecting the first device group is smaller than the preset threshold, the physical loop corresponding to the first logical loop is determined to be a true loop.

In the method for determining a false loop provided by the embodiment of the present disclosure, a logical loop in a network may be obtained based on a logical topology map, and then position information of a light path connecting a first device group in the first logical loop may be obtained according to a device unique identifier and a port identifier of the device group; and then, judging whether two optical cable segments with the position information similarity larger than or equal to a preset threshold exist in different optical paths connected with the first equipment group, and if two optical cable segments with the position information similarity larger than the preset threshold exist, determining that a false loop exists in a physical loop corresponding to the first logic loop. That is, a loop of a logical loop may be determined by logical topology information, and then similarity of location information of a device group in the logical loop is determined, if optical cable segments with the same location exist in different optical paths, or optical cable segments with the same location exist, or optical cable segments with relatively close locations exist, it is determined that a false loop exists in the optical paths, so that it may be determined which devices may not be able to recover a network when an optical cable is damaged and failed, and optimization of the network may be performed on the devices in advance, for example, a network path is re-planned, a new optical cable is laid, and the problem that the network cannot be quickly recovered when an optical cable fails when the network forming the loop does not play a role in protecting the loop can be avoided, so that stability of the network can be improved in a physical layer.

In the embodiment of the present disclosure, if the logical topology of the communication network can be directly obtained, the logical loop in the network can be directly determined based on the logical topology of the communication network. If there is no logical topology map of the communication network, the logical topology map of the network may be generated according to the logical topology connection relationship in the logical topology connection table of the network.

Optionally, in the method for determining a false loop provided in the embodiment of the present disclosure, before the foregoing S201, the following S205 may further be included:

Optionally, the logical topology connection table may include: the system comprises a logical topology unique identifier of each connection, an equipment unique identifier of each connected A-end equipment, an equipment unique identifier of Z-end equipment, a port identifier of the A-end equipment connected with a port of the Z-end equipment, and a port identifier of the Z-end equipment connected with the port of the A-end equipment.

The A-end equipment and the Z-end equipment are two pieces of end equipment of one equipment group.

Illustratively, the data structure of the logical topology connection table may include: the system comprises an A-end equipment unique identifier, an A-end connection port unique identifier, a Z-end equipment connection port unique identifier and a logic topology unique identifier.

Illustratively, table 1 is an exemplary table of a logical topology connection table provided by the embodiment of the present disclosure.

TABLE 1

Unique identifier of A-side equipment<fk>	0001	0001	0002
				A-side equipment port identification<fk>	0001	0002	0003
Unique identifier of Z-terminal equipment<fk>	0002	0003	0003
				Z-terminal equipment port identification<fk>	0003	0001	0002
Logical topology unique identification<pk>	0001	0002	0003

Specifically, it can be determined from table 1 that the device of the device unique identifier 0001 is connected to the device of the device unique identifier 0002, the device of the device unique identifier 0001 is connected to the device of the device unique identifier 0003, and the device of the device unique identifier 0002 is connected to the device of the device unique identifier 0003.

Optionally, the device information of the device group and the port information of the device group connection may be obtained according to a pre-constructed logical query model. Wherein the logical query model comprises: a logical topology connection table, an equipment information table and an equipment port information table.

Illustratively, the device information table may include: the device unique identification, the device name, the device type and the device model; the port information table may include: unique device identification, unique port identification, port type, and port number.

Table 2 is an exemplary table of a device information table provided in the embodiment of the present disclosure, where the example in table 2 is illustrated by including a device unique identifier and a device name.

TABLE 2

Device unique identifier<pk>	0001	0002	0003	0004	0005
						Device name	1	2	3	4	5

Table 3 is an exemplary table of a port information table provided in the embodiment of the present disclosure, where table 3 exemplifies that the port information table includes a device unique identifier, a port identifier, and a port number.

TABLE 3

Device unique identifier<fk>	0001	0001	0001	0001	0002	0002	0002	0002
									Port identification<pk>	0001	0002	0003	0004	0001	0002	0003	0004
Port numbering	1	2	3	4	1	2	3	4

In the embodiment of the present disclosure, the device names of two devices in the connected device group may be searched from the device information table according to the device unique identifiers of the a-side device and the Z-side device corresponding to each logical topology unique identifier in the logical topology table, so as to generate a connection node in the logical topology map. The ports connecting the a-side device and the Z-side device can be searched from the port information table according to the port identifiers of the a-side device and the Z-side device corresponding to each logical topology unique identifier in the logical topology table.

Exemplarily, by combining the device unique identifier of each device in the device group corresponding to one logical topology unique identifier in table 2 and the device unique identifier in table 3, it can be determined that the node corresponding to the device 1 is connected to the node corresponding to the device 2, the node corresponding to the device 2 is connected to the node corresponding to the device 3, and the node corresponding to the device 1 is connected to the node corresponding to the device 3, so that the logical topology shown in (a) in fig. 1 can be obtained.

Based on the scheme, the logic diagram spectrogram of the network can be quickly generated according to the logic topology relation in the logic topology information table of the network, so that the association relation between the logic topology and the physical topology can be constructed according to the logic topology diagram, and accurate reference basis is provided for determining the false loop phenomenon in the physical connection.

It should be noted that, in the embodiment of the present disclosure, before the above-mentioned S203, it may be determined whether the devices in one device group are station devices. For example, it may be determined whether the devices in one device group are station devices according to the position information of each optical cable segment in the optical path.

Exemplarily, if the number of the optical cable sections directly and physically connected with the first device is greater than or equal to a preset number, determining that the first device is a station device; and if the number of the optical cable sections directly and physically connected with the first equipment is less than the preset number, determining that the first equipment is non-site equipment.

Exemplarily, fig. 3 is a schematic diagram of a station provided in the embodiment of the present disclosure, and as shown in fig. 3, the station includes 3 stations, which are station 1, station 2, and station 3, respectively. In the peripheral area of each station, the number of the optical cables connected to the outside of each station is larger and the positions of the optical cables are the same.

It can be understood that, in the embodiment of the present disclosure, if one device is a station device, a circular buffer area is set with the station device as a center of a circle, and when it is determined whether a false loop exists in an actually laid physical loop corresponding to a logical loop, the determination of the optical cable information inside the buffer area is rejected.

Further, in the case of determining whether the cable segment satisfies the cable segment of the pseudo loop, the above-mentioned S203 mind is performed by the following S23:

and S23, determining whether two optical cable segments with the similarity of the position information larger than or equal to a preset threshold exist in the optical cable segments outside the buffer area in different optical paths connecting the first equipment group.

Based on the scheme, whether the optical cable convergence phenomenon exists or not can be determined by combining the spatial position information of the optical cable resources, if the optical cable convergence phenomenon exists, the equipment with the optical cable convergence phenomenon is determined to be station equipment, and when a false loop is judged, the optical cable laying section close to the station is removed, so that the optical cable section without the false loop can be prevented from being judged to be a false loop optical cable section.

Optionally, in the method for determining a false loop provided in the embodiment of the present disclosure, the step S201 may be specifically executed by the following steps S21a and S21 b:

and S21a, acquiring the logic path of each equipment group based on the logic topological graph.

One logical path may indicate a logical data transmission path from one end device of the device group to another end device.

Alternatively, the logical loop table may be generated based on the connection relationship indicated in the logical topology map or the connection relationship indicated in the logical topology connection table. Illustratively, the logical loop table may be generated from the logical topology connection table and the device information table.

Illustratively, the logical loop table may include: path name (logical loop name), sub-path A end equipment, sub-path Z end equipment, logical sub-path serial number, logical sub-path node record and loop code.

In the logical loop table, each logical path is defined as a sub-path of the device group.

For example, assuming that the logical topology of one network is the logical topology shown in (a) in fig. 4, a logical path between each device group may be generated in combination with the connection relationship of the nodes in the logical topology. As shown in table 4, an exemplary table of the logical loop associated with node 1 in (a) of fig. 4 is shown. Table 4 below shows logical paths between nodes connected to node 1, with node 1 as a reference node.

Illustratively, the path name may be generated from the node device identifier of the device group, and the sub-path node record may be generated from the node device identifier included in the sub-path.

TABLE 4

And S21b, if the second device group comprises at least two logic paths, determining that a logic loop is included between the second device group.

The second device group is any one device group in the logic topological graph.

It is understood that if the number of logical paths between one device group is greater than 1, it indicates that a logical loop is included between the device groups, and if the number of logical paths between one device group is equal to 1, it indicates that a logical loop is not included between the device groups.

In connection with table 1, the device groups 1-2 include 3 logic paths, the device groups 1-3 include 3 logic paths, the device groups 1-4 include 4 logic paths, and the device groups 1-5 include 4 logic paths. I.e. device groups 1-2, 1-3, 1-4, 1-5, all comprise logical loops.

Based on the scheme, according to the logical topological graph, the logical paths in each device group are obtained first, then the number of the logical paths in the device group is determined, and in the case that one device group includes at least two logical paths, it can be determined that a logical loop is included between the device groups.

Optionally, in the method for determining a false loop provided in the embodiment of the present disclosure, the step S202 may specifically be implemented by the following steps S22a to S22c:

s22a, obtaining M optical path identifiers of M optical paths of the first device group in the first logical loop according to the optical fiber optical path table and the device unique identifier and the port identifier in the first device group.

Wherein M is an integer greater than or equal to 2.

Illustratively, the fiber optic routing table may include: the optical path identification comprises an optical path ID, an optical path name, an A-end port identification, an A-end equipment unique identification, a Z-end port identification and a Z-end equipment unique identification.

Unique identifier of A-side equipment	0001	0002
			Z-port identification	0002	0004

Based on table 5 and the device unique identifier, two optical paths, namely, optical path 0001 and optical path 0002, may exist between the device of device unique identifier 0001 and the device of device unique identifier 0002 according to the device identifier, where the optical path of optical path identifier 0001 is connected to the port of port identifier 0001 in the device of device unique identifier 0001 through the port of port identifier 0001 in the device of device unique identifier 0001. The optical path with the optical path identifier of 0002 is connected with the port identifier of 0002 in the device with the device unique identifier 0001 and the port with the port identifier of 0004 in the device with the device unique identifier 0001.

S22b, acquiring the optical cable segment identification included in each optical path in the M optical paths according to the optical fiber core table and the M optical path identifications.

Wherein the cable segment table may include: optical cable section ID, optical cable section name, management area, optical cable (external key: optical cable ID), optical cable A end geographic coordinate and optical cable Z end geographic coordinate.

TABLE 7

The cable segments for each optical path may be obtained from the cable segment table shown in fig. 7 in conjunction with the cable segment IDs in table 6.

In the embodiments of the present disclosure, a physical model for determining a physical path may be constructed based on the optical cable segment table, the optical cable core table, and the optical fiber path table. The optical fiber path table is connected with the external key of the optical cable fiber core table to form an optical path ID, and the optical cable fiber core table is connected with the external key of the optical cable section table to form an optical cable section ID. The method comprises the steps of acquiring equipment unique identification of equipment of an equipment group, using the equipment unique identification as an external key for connecting the optical fiber lightroad sign, determining an optical path ID of the equipment group from an optical fiber lightpath table through the equipment unique identification, determining an optical cable section ID from an optical cable fiber core table based on the optical path ID, and acquiring the optical cable section ID and geographic coordinates of the optical cable section from the optical cable section table based on the optical cable section ID.

After obtaining each cable segment, a physical loop path table may be generated based on the obtained information, where one physical loop path table may include: path name, A-side equipment, Z-side equipment, physical sub-path serial number, physical sub-path node record and physical path code.
