[ detailed description ] embodiments
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, the terms "inner", "outer", "longitudinal", "lateral", "upper", "lower", "top", "bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are for convenience only to describe the present invention without requiring the present invention to be necessarily constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1:
embodiment 1 of the present invention provides an optical fiber misconnection detection method, as shown in fig. 1, including:
in step 201, a station a sends an interconnection port, an IP address, and a subnet mask of a station B, which establishes an optical fiber line connection with itself, to an opposite station by carrying them in a first detection message.
In step 202, the opposite-end site verifies whether the interconnection port, the IP address and the subnet mask of the site B carried in the first detection message are matched with its own attributes, if the matching is performed to verify that the connection of the optical fiber line is correct, otherwise, the misconnection of the optical fiber is verified, and a first detection response is returned to the site a; wherein the first detection response carries a verification result.
According to the embodiment of the invention, the opposite end information of the optical fiber line connection which should be established logically is sent to the opposite end through the optical fiber line connection between the station and the station, whether the actually established optical fiber line connection is consistent with the logic theory is verified based on the matching of the opposite end and the local related information, if so, the optical fiber line connection is verified to be correct, otherwise, the optical fiber misconnection is verified, and thus, the purpose of automatic detection is realized.
With reference to the embodiment of the present invention, when the station a determines that the incoming optical fiber is misconnected, as shown in fig. 2, the method further includes:
in step 301, station a sends a request for interconnection information to the database.
In the embodiment of the present invention, the database may be a database service provided by a third party platform independently from each site; before the database used in the embodiment of the present invention is used specifically, it must be satisfied that once each station relates to the optical fiber line connection of its own included board, the corresponding connection information is synchronously updated to the database, so that it can be ensured that the information included in the corresponding database can be accurately utilized in each association extension scheme of the present invention.
In step 302, an interconnection response message returned by the database is received, where the interconnection response message carries an interconnection port, an IP address, and a subnet mask of a site B that is maintained by the database and is connected to the site a by an optical fiber line.
In practical situations, the connection information of the optical fiber lines between the stations in the database may be pre-imported into the database when the network architecture model is planned, that is, the connection information of the optical fiber lines in the data may be ahead of the connection information of the optical fiber lines already established in the actual scene. However, another preferred implementation exists in which the fiber line connection information between sites in the database is synchronized to the database after the relevant plug-in physical scenario operation is completed. The former has the advantage that once a connection error of a certain station is detected, other associated stations causing chain reaction due to optical fiber misconnection of the station can be found according to the complete optical fiber line connection information stored in the database, wherein the associated stations may include some stations which do not currently physically complete optical fiber line connection, so that the possibility of misconnection of the corresponding station and the complexity of error arrangement of the corresponding station can be saved, that is, after a source station which finds out the optical fiber line connection error is eliminated, the optical fiber line connection operation of the associated station which does not physically establish optical fiber line connection is performed.
With reference to the embodiment of the present invention, one or more groups are obtained in the database by using the same site of the fiber line connection established by the single board as an allocation basis, as shown in fig. 3, the association steps in embodiment 1 are further fused to perform relatively complete logic display:
in step 200, the station a obtains a first group of boards that establish an optical fiber connection with the station B according to the station relationship of the optical fiber connection recorded in the database.
In the embodiments of the present invention, the first, second, etc. restrictive descriptions are not intended to refer to a specific order, but only to allow the correspondingly restricted objects to be separated from the same class, and are used for convenience in describing two or more different objects in the same class, and should not be interpreted in a further restrictive sense.
The site A carries the interconnection port, the IP website and the subnet mask of the site B in a first detection message through a first single board in the first group of single boards and sends the first detection message to an opposite-end site; after receiving a result of verifying that the optical fiber line connection returned by the opposite end is correct, that is, the implementation subject of step 201 to step 202 in embodiment 1 directly appears as a first board in the first group of boards in the station a in this embodiment (the corresponding descriptions of step 201 and step 202 in fig. 3 are also modified appropriately), the method further includes:
in step 203, the station a sends a second detection message carrying the identification codes of the heartbeat messages of the remaining boards in the first group of boards to the opposite end through the first board in the first group of boards, where the identification code of one heartbeat message uniquely corresponds to one board in the first group of boards.
It should be noted that, the second detection message and the first detection message are only for their purpose to complete the detection, but there is a large difference between them. In the embodiment of the invention, the first detection message mainly carries the interconnection port of the opposite terminal, the IP address and the subnet mask, the second detection message mainly carries the heartbeat message of the related single board in the first group of single boards, and at the moment, the second detection message does not need to carry the interconnection port of the opposite terminal, the IP address and the subnet mask, so that the message content can be compressed to the utmost extent.
In the embodiment of the invention, although the heartbeat message is used for expression, the actual meaning of the heartbeat message is different from the heartbeat message described by the conventional method; in the conventional internet category, the understood heartbeat message is sent at preset periodic intervals, and a means for keeping a connection channel between two nodes alive or not is provided.
In step 204, the station a obtains the heartbeat messages carrying the corresponding unique identification codes corresponding to the remaining single boards belonging to the first group of single boards, and sends respective heartbeat messages to the opposite end by using the remaining single boards as main bodies.
In step 205, the station a obtains the second detection response returned by the peer station, where the peer determines that other boards of the peer station have received heartbeat messages with the same identification code carried in the corresponding second detection message and/or receive timeout after the peer obtains the second detection message.
The embodiment of the invention utilizes the single board, the station, the machine room and the working characteristics of the matched plug-in personnel to establish the associated database, and the optical fiber misconnection in the optical network is automatically and rapidly detected under the condition of matching with the optical fiber line connection detection of the station without increasing the labor cost of engineering personnel.
The modes embodied in steps 200 to 205 can further reduce the bandwidth occupation of the links between the sites, because the authentication mechanism of the corresponding heartbeat message is only the identification code, the list of the boards under the matched sites is mapped one by one through the corresponding list of the identification codes, and the transmission of the list of the identification codes is also completed through the pair of boards which completes the correct connection check of the optical fiber line in embodiment 1.
When the opposite end confirms that other single boards of the opposite end receive heartbeat messages with the same identification codes carried in corresponding second detection messages, the second detection response carries information for verifying that the optical fiber circuit connection of all the single boards in the first group of single boards is correct; when the opposite terminal confirms that the heartbeat message received by other single boards of the opposite terminal is overtime, the second detection correspondingly carries information of verifying optical fiber misconnection of the corresponding single board in the opposite terminal.
In a preferred implementation scheme, the database further stores records of the corresponding fiber line connection operators of each board in each site, specifically:
when the plugging operation is performed on each single board, the plugging personnel connected with the single board optical fiber line on each station records the station and/or single board information where the plugging operation executed by the plugging personnel is located into the database by scanning the two-dimensional codes on the corresponding station and/or single board in advance.
When the returned first detection response carries a detection result of the optical fiber misconnection including the interconnection port of the site C, the IP address, and the subnet mask, as shown in fig. 4, the method further includes:
in step 501, the station a obtains the current station with the misconnected optical fibers from the database, and performs the plugging operation on the plug wire operator X in the history.
In step 502, the plug-in personnel X is used as a keyword to search for associated data objects in a database of the station requiring fiber circuit connection verification in this round, so as to locate one or more stations or one or more boards using the plug-in personnel X as a site for performing plug-in operations.
In step 503, the located personnel X for plugging the cable is used as one or more stations for performing the plugging operation, or one or more single boards are used as main bodies, and corresponding detection messages are sent to respective opposite end stations.
This has the advantage that the work careful nature of the patch personnel is further subdivided and associated with the detection of fibre optic line connections; this process is effectively realized through the above steps 501 to 503 in the embodiment of the present invention. The implementation of the method is still based on the application of the embodiment of the invention to the database, and the storage and maintenance of the data relation in the database.
The station which needs to perform the fiber line connection verification in this round is also calibrated according to the machine room as a second division dimension, where the second division dimension is relative to the above-indicated division dimension of the single boards belonging to the same group, and the single boards of the same group have been used as a clear definition above, that is, a plurality of single boards establishing fiber line connection with the same station at the opposite end are logically and theoretically confirmed in one station to form a group. In an embodiment of the present invention, after the second division dimension is further introduced, the method further includes:
and searching a relevant data object of a database of the station needing optical fiber line connection verification in the same machine room area range in the current round by taking the wire plugging person X as a keyword, thereby positioning one or more stations or one or more single boards which are taken as the wire plugging person X to execute wire plugging operation.
When the returned detection result of the optical fiber misconnection including the interconnection port of the site C, the IP address, and the subnet mask, which is carried in the first detection response, is carried, the result of the description herein is that the optical fiber circuit connection of the site a has the optical fiber misconnection (the unit of misconnection may be a single board, or may refer to the entire site a, and the actual situation is applicable to which expression, according to the above extended implementation schemes, the method further includes:
and directly updating the state of the optical fiber line connection corresponding to the site C in the database to be optical fiber misconnection, and skipping the subsequent process of initiating the detection message by taking the site C as a main body. Here, it is to be noted that, once the response message of the first detection message includes the detection result of the optical fiber misconnection of the interconnection port, the IP address and the subnet mask of the other site C, according to the optical fiber line connection between the sites, especially, a one-to-one connection characteristic between the ports, at this time, the site C that can directly and definitely respond must also have the optical fiber misconnection, and the effect of such processing is that, when the detection of the optical fiber misconnection of the interconnection port, the IP address and the subnet mask of the site C is further involved later, the corresponding detection conclusion can be directly obtained from the database, thereby improving the detection efficiency in the entire system.
When the port state is DOWN, the detection of optical fiber misconnection is not carried out, and an optical fiber misconnection alarm is not reported; when the port state is UP, the optical fiber misconnection is detected, and when the optical fiber misconnection is verified, an optical fiber misconnection alarm is reported. The port status of the station is also described in embodiment 3 for different situations.
Example 2:
the embodiment of the invention provides an optical fiber misconnection detection system, which comprises a station A and a station X, wherein the station A is only used for forming description individuality with each station of the same type, and similarly, the station A can also be described as a station B, a station C, a station D and the like, and the character X in the corresponding station X is also only used for indicating that the corresponding station is used as an opposite station which establishes a physical optical fiber line connection with the station A before the optical fiber line connection is verified to be correct by verification, and is not necessarily the station B which establishes an optical fiber line connection with the station A in the following text description, so that the uncertainty existing in the corresponding station A and the characteristic to be confirmed are represented by X, and once the optical fiber line connection is confirmed to be correct, the station X is also the corresponding station B. Specifically, the method comprises the following steps:
and the site A carries the interconnection port, the IP website and the subnet mask of the site B which is connected with the site A by the optical fiber line in a first detection message and sends the first detection message to the opposite site X.
The opposite terminal station X verifies whether the interconnection port, the IP website and the subnet mask of the station B carried in the first detection message are matched with the attributes of the opposite terminal station X, if so, the optical fiber line connection is verified to be correct, otherwise, the optical fiber misconnection is verified, and a first detection response is returned to the station A; wherein the first detection response carries a verification result.

Referring to fig. 9, the Site of Site-a is originally connected to Site-C through an optical fiber, but is misconnected to the port of Site-B, at this time, the port UP can perform optical fiber misconnection detection, and since the Site-B receives Site information and is not matched with the local Site, the optical fiber misconnection can be detected.
