Background

The cluster router is generally composed of a plurality of machine frames in a cascade connection mode, optical cables used in the cascade connection mode are dozens or even hundreds, the optical cables cannot be connected randomly, and the optical cables need to be connected according to a specified topological relation according to networking conditions. Once the optical cable connection is wrong, the service packet can be lost and even the service can be interrupted. The connection relationship between the optical ports in the cluster router is usually indicated by manufacturers in a specification or an operation manual, and users are relied on to ensure the accuracy of the connection between the optical ports. However, when the number of optical ports is large, not only the complexity of connection increases, but also the accuracy of connection between the optical ports is difficult to ensure. In view of this situation, some methods are used to detect the accuracy of the connection between the optical ports of the cluster router, for example, the cluster router master board receives the optical port information of each optical port reported on each switching board in real time and checks the information to determine whether the connection between the optical ports is correct. However, the above method will increase the complexity of detecting the optical port connection and decrease the reliability.

Detailed Description

The technical scheme of the invention is further elaborated by combining the drawings and the specific embodiments in the specification. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, an optical interface connection detection method provided in the embodiment of the present invention is applied to a switch board, and includes the following steps:

s101: the method comprises the steps that a switching single board where an optical port to be detected is located obtains position information of the optical port to be detected;

it can be understood that the cluster router generally includes a plurality of core routers and a central connection router, and each router includes one or more switch boards (also referred to as switch boards), and each switch board also includes one or more optical ports. The optical cable connection between each optical port can ensure that the cluster router can normally work only if the specified topological relation is met. When optical cable connection detection needs to be performed on an optical port (referred to as an optical port to be detected for short) of a certain switching board in a certain router, the switching board (referred to as the switching board where the optical port to be detected is located for short) acquires position information of the optical port to be detected. The frame number of the optical port to be detected represents a machine frame where the optical port to be detected is located, and the machine frame comprises a service core frame consisting of a core router and a central switching frame consisting of a central connection router; the slot position number of the optical port to be detected represents the exchange single board where the optical port to be detected is located; and the optical port number of the optical port to be detected represents the identifier of the optical port to be detected on the exchange single board where the optical port to be detected is located. Because each optical port has unique address information, that is, the position information of each optical port has a unique corresponding relationship with the optical port, the optical port to be detected can be uniquely determined according to the position information of the optical port to be detected.

Here, the exchange board where the optical port to be detected is located acquires the position information of the optical port to be detected, which may be that the exchange board where the optical port to be detected is located detects that the optical cable is connected to the optical port to be detected, that is, when the exchange board where the optical port to be detected is located detects that the optical port to be detected has a signal, the exchange board triggers a position information collection process of the optical port to be detected, that is, acquires the position information of the optical port to be detected; or the exchange single board where the optical port to be detected is located may trigger the position information collection process of the optical port to be detected at a set time interval. It should be noted that the optical port to be detected may be one optical port or may be multiple optical ports, and in this embodiment, the optical port to be detected is taken as one optical port as an example.

S102: and the exchange single board where the optical port to be detected is located sends out the position information of the optical port to be detected through the optical port to be detected.

Here, the exchange board where the optical port to be detected is located sends the position information of the optical port to be detected through the optical port to be detected, where the exchange board where the optical port to be detected is located may send the position information of the optical port to be detected to the target optical port through the optical port to be detected when detecting that a set sending condition is met, and the set sending condition may be that an optical cable is connected to the optical port to be detected or that a difference between times of sending the position information of the optical port to be detected last time at the current time is equal to a set time interval. When the optical port to be detected is accessed by an optical cable, the exchange veneer where the optical port to be detected is located sends the position information of the optical port to be detected to a target optical port through the optical port to be detected, which can be understood as that the exchange veneer where the optical port to be detected is located sends the position information of the optical port to be detected outwards through the optical cable with one end inserted into the optical port to be detected, and the target optical port is an optical port connected with the other end of the optical cable.

It should be noted that the optical port to be detected and the target optical port may be located on the same switch board of the same router, the optical port to be detected and the target optical port may also be located on different switch boards of the same router, respectively, and the optical port to be detected and the target optical port may also be located on switch boards of different routers, respectively. That is to say, the switch board where the optical port to be detected is located and the switch board where the target optical port is located may be the same switch board or different switch boards in different application scenarios.

In summary, in the optical interface connection detection method provided in the above embodiment, the exchange board where the optical interface to be detected is located sends the position information of the optical interface to be detected to the target optical interface, so that the exchange board where the target optical interface is located or the exchange board where the optical interface to be detected is located can detect whether the connection between the optical interface to be detected and the target optical interface is correct according to the position information of the optical interface to be detected, that is, the exchange board can complete the detection of whether the connection between the optical interface to be detected and the target optical interface is correct, thereby reducing the complexity of detecting the optical interface connection and improving the reliability of detecting the optical interface connection.

In an optional embodiment, the sending out, by the exchange board where the optical port to be detected is located through the optical port to be detected, the position information of the optical port to be detected includes:

Specifically, when the switching board where the optical port to be detected is located determines that the optical cable is connected to the optical port to be detected, that is, when the optical port to be detected is detected to have a signal, the switching board sends out the position information of the optical port to be detected through the optical port to be detected; or, according to a set time interval, the exchange board where the optical port to be detected is located sends out the position information of the optical port to be detected through the optical port to be detected by taking the set time interval as a cycle.

Therefore, when the switching single board where the optical port to be detected is located detects that the optical port to be detected has the optical cable access, the position information of the optical port to be detected is sent out through the optical port to be detected, and timeliness and rapidity of detection of optical port connection are improved. And the exchange single board where the optical port to be detected is located sends out the position information of the optical port to be detected through the optical port to be detected at set time intervals, so that the periodic detection of the optical port connection is realized, and particularly, the detection of the optical port connection can be automatically carried out again after the connection of the optical port is changed. In addition, the diversity of the way of detecting the optical port connection is also enhanced.

Therefore, the exchange single board where the optical port to be detected is located can accelerate the speed of outward transmission of the position information of the optical port to be detected by packaging the position information of the optical port to be detected to the set detection message or encoding the position information of the optical port to be detected and sending the position information of the optical port to be detected in a detection message or code stream mode, so that the transmission time is saved, and the interference of the external environment can be effectively avoided.

In an optional embodiment, after the switch board where the optical port to be detected is located sends out the position information of the optical port to be detected through the optical port to be detected, the method further includes:

the exchange single board where the optical port to be detected is located acquires the position information of the target optical port, wherein the target optical port is the optical port which receives the position information of the optical port to be detected;

Specifically, the switching board where the optical port to be detected is located acquires position information of a target optical port, acquires position information of an expected optical port corresponding to the target optical port according to a set optical port connection topology relationship, and determines that the target optical port and the optical port to be detected are correctly connected when the position information of the optical port to be detected is consistent with the position information of the expected optical port corresponding to the target optical port; and when the position information of the optical port to be detected is inconsistent with the position information of the expected optical port corresponding to the target optical port, determining that the target optical port is connected with the optical port to be detected in a wrong way. Or, the switching board where the optical port to be detected is located acquires the position information of the target optical port, and acquires the position information of the expected optical port corresponding to the optical port to be detected according to the set optical port connection topology relation, and when the position information of the expected optical port corresponding to the optical port to be detected is consistent with the position information of the target optical port, it is determined that the target optical port is correctly connected with the optical port to be detected; and when the position information of the expected optical port corresponding to the optical port to be detected is inconsistent with the position information of the target optical port, determining that the target optical port is connected with the optical port to be detected in a wrong way.

Here, if the position information of the optical port to be detected includes a frame number, a slot number, and an optical port number of the optical port to be detected, the position information of the optical port to be detected and the position information of the desired optical port corresponding to the target optical port are consistent in a one-to-one correspondence that the frame number, the slot number, and the optical port number of the optical port to be detected are the same as the frame number, the slot number, and the optical port number of the desired optical port corresponding to the target optical port, and the position information of the optical port to be detected and the position information of the desired optical port corresponding to the target optical port are inconsistent in a one-to-one correspondence that at least one of the frame number, the slot number, and the optical port number of the desired optical port corresponding to the target optical port is not the same as the frame number, the slot number, and the optical; correspondingly, the position information of the expected optical port corresponding to the optical port to be detected and the position information of the target optical port are consistent, namely, the frame number, the slot number and the optical port number of the expected optical port corresponding to the optical port to be detected are in one-to-one correspondence with the frame number, the slot number and the optical port number of the target optical port, and the position information of the expected optical port corresponding to the optical port to be detected and the position information of the target optical port are inconsistent, namely, at least one of the frame number, the slot number and the optical port number of the expected optical port corresponding to the optical port to be detected is in one-to-one correspondence with the frame number, the slot number and the optical port number of the target optical port.

It should be noted that the connections between the optical ports are in one-to-one correspondence, that is, a desired optical port corresponding to each optical port is specified in the optical port connection topological relation, that is, each optical port should be connected to the desired optical port corresponding to the optical port. In practical application, the optical interface connection topological relation can be described in a table mode. For example, if the optical port a is an expected optical port uniquely corresponding to the optical port B, the frame number, the slot number, and the optical port number of the optical port a may be bound to the frame number, the slot number, and the optical port number of the optical port B to form a connection topology relationship between the optical port a and the optical port B, and the connection topology relationship may be stored in a table manner. The optical port connection topology relation can be preset according to actual conditions and stored in the switch board. For the switching board where the optical port to be detected is located, the connection topology relations corresponding to all the optical ports of the switching board can be stored, and the connection topology relations corresponding to the optical ports of other switching boards can also be stored. When the optical port to be detected and the target optical port are located in the same exchange single board, the exchange single board can actively acquire the position information of the target optical port after acquiring the target optical port receiving the position information of the optical port to be detected. It should be noted that, when the optical port to be detected and the target optical port are located in different switch boards, and the switch board where the target optical port is located determines that the target optical port has an optical cable access, that is, when it is detected that the target optical port has a signal, the switch board where the target optical port is located may send the position information of the target optical port to the optical port to be detected through the target optical port, so that the switch board where the optical port to be detected is located obtains the position information of the target optical port.

Thus, when the optical port to be detected and the target optical port are located on the same switch board, the same switch board can determine whether the connection between the target optical port and the optical port to be detected is correct or not according to the set optical port connection topology relationship, the position information of the target optical port and the position information of the optical port to be detected, and the detection of the connection between the optical ports can be completed on the same switch board; when the optical port to be detected and the target optical port are located in different switch boards, the switch board where the optical port to be detected is located or the switch board where the target optical port is located can also complete detection, and the switch board directly realizes detection of optical port connection, so that the problems of delay and external interference caused by introducing a third party for detection are avoided, and the detection process is simple, the detection speed is high, and the reliability is high.

In an optional embodiment, the method further comprises:

Here, the sending of the alarm message may be that the switch board where the optical port to be detected is located sends a connection error message between the target optical port and the optical port to be detected in a manner of a command line, so that the connection error message between the target optical port and the optical port to be detected is displayed on a display interface of a user telnet cluster router. The sending of the warning message may also be directly sending a warning message to a user to inform that the connection between the target optical port and the optical port to be detected is wrong. The sending of the warning message may also be triggering of a set indicator light to light up so as to inform that the connection between the target optical port and the optical port to be detected is wrong. For example, suppose that a connection status indicator lamp is correspondingly arranged on each optical port on the switch board, and when the optical ports are correctly connected, the connection status indicator lamp corresponding to the optical port is not turned on; and when the connection of the light port is wrong, the connection state indicator lamp corresponding to the light port is lightened. The switching board where the optical port to be detected is located sends a link establishment request through the target optical port, which can be understood as that the switching board where the optical port to be detected is located sends a set high-flow message to the optical port to be detected through the target optical port, so as to inform that the connection between the target optical port and the optical port to be detected is correct. The switch board where the optical port to be detected is located sends out a link establishment request through the target optical port, which may be regarded as controlling the optical cable link establishment between the target optical port and the optical port to be detected. And when the exchange single board where the optical port to be detected is located determines that the target optical port is connected with the optical port to be detected in a wrong way, sending a prompt message carrying the position information of the expected optical port corresponding to the target optical port or the position information of the expected optical port corresponding to the optical port to be detected so as to inform a user of realizing correct connection between the optical ports according to the prompt message. In addition, when the switch board where the optical port to be detected is located determines that the connection between the target optical port and the optical port to be detected is incorrect, a link establishment request is not sent through the target optical port, which may be regarded as controlling the optical cable link between the target optical port and the optical port to be detected to reset, so as to avoid the situation that the optical cable is inserted incorrectly and the optical cable is lost or the service is interrupted after the optical cable link establishment is successful.

Therefore, when the target optical port is connected with the optical port to be detected in a wrong way, namely the optical cable is inserted in a wrong way, the optical cable is prompted to be inserted in a wrong way by sending an alarm, a prompt message and the like, the prompt mode is visual, and the prompt effect is good. When the connection between the target optical port and the optical port to be detected is correct, namely the optical cable is not inserted in a wrong way, the optical cable link is controlled to be established, and when the connection between the target optical port and the optical port to be detected is wrong, namely the optical cable is inserted in a wrong way, the optical cable link is controlled to be reset, so that the situations of packet loss or service interruption after the optical cable link is established successfully due to the optical cable insertion in a wrong way are avoided, and the detection flexibility is improved.

Referring to fig. 2, the method for detecting an optical interface connection provided in the embodiment of the present invention is applied to a switch board, and includes the following steps:

s201: the method comprises the steps that a switching single board where a target optical port is located obtains position information of an optical port to be detected and position information of the target optical port, wherein the target optical port is the optical port which receives the position information of the optical port to be detected;

specifically, when the optical port to be detected and the target optical port are located in different switch boards, that is, the switch board where the optical port to be detected is located and the switch board where the target optical port is located are different switch boards, the switch board where the target optical port is located receives the position information of the optical port to be detected sent by the switch board where the optical port to be detected is located, and obtains the position information of the target optical port.

S202: and the exchange single board where the target optical port is located determines whether the connection between the target optical port and the optical port to be detected is correct or not according to the set optical port connection topological relation, the position information of the target optical port and the position information of the optical port to be detected.

Specifically, the switching board where the target optical port is located acquires position information of an expected optical port corresponding to the target optical port according to a set optical port connection topology relationship, and determines that the target optical port and the to-be-detected optical port are correctly connected when the position information of the to-be-detected optical port is consistent with the position information of the expected optical port corresponding to the target optical port; and when the position information of the optical port to be detected is inconsistent with the position information of the expected optical port corresponding to the target optical port, determining that the target optical port is connected with the optical port to be detected in a wrong way. Or, the exchange board where the target optical port is located acquires the position information of the expected optical port corresponding to the optical port to be detected according to the set optical port connection topology relationship, and when the position information of the expected optical port corresponding to the optical port to be detected is consistent with the position information of the target optical port, it is determined that the target optical port is correctly connected with the optical port to be detected; and when the position information of the expected optical port corresponding to the optical port to be detected is inconsistent with the position information of the target optical port, determining that the target optical port is connected with the optical port to be detected in a wrong way.

It should be noted that the connections between the optical ports are in one-to-one correspondence, that is, a desired optical port uniquely corresponding to each optical port is specified in the optical port connection topological relation, that is, each optical port must be connected to the desired optical port corresponding to the optical port. In practical application, the optical interface connection topological relation can be described in a table mode. For example, if the optical port a is the only expected optical port that can be correspondingly connected to the optical port B, the frame number, the slot number, and the optical port number of the optical port a may be bound to the frame number, the slot number, and the optical port number of the optical port B to form a connection topology relationship between the optical port a and the optical port B, and the connection topology relationship may be stored in a table manner. The optical port connection topology relation can be preset according to actual conditions and stored in the switch board. For the switching board where the target optical port is located, the connection topology relations corresponding to all the optical ports of the switching board can be stored, and the connection topology relations corresponding to the optical ports of other switching boards can also be stored.

Therefore, when the optical port to be detected and the target optical port are located in different switch boards, the switch board where the target optical port is located determines whether the connection between the target optical port and the optical port to be detected is correct according to the set optical port connection topology relation, the position information of the target optical port and the position information of the optical port to be detected, and the switch board directly detects the optical port connection, so that the problems of time delay and external interference caused by introducing a third party for detection are solved, and the switch board is simple in detection process, high in detection speed and high in reliability.

In an optional embodiment, the method further comprises:

Here, the switching board where the target optical port is located sends the position information of the target optical port through the target optical port, which may be understood as that the switching board where the target optical port is located sends the position information of the target optical port to the optical port to be detected through the target optical port. The switching board where the target optical port is located sends the position information of the target optical port to the optical port to be detected through the target optical port, where the switching board where the target optical port is located sends the position information of the target optical port to the optical port to be detected through the target optical port when detecting that a set sending condition is met, and the set sending condition may be that an optical cable is connected to the target optical port or that a difference between times of sending the position information of the target optical port last time at the current time is equal to a set time interval. When the target optical port is accessed by an optical cable, the exchange single board where the target optical port is located sends the position information of the target optical port to the optical port to be detected through the target optical port, which can be understood as that the exchange single board where the target optical port is located sends the position information of the target optical port outwards through the optical cable with one end inserted into the target optical port.

Therefore, the exchange single board where the target optical port is located sends the position information of the target optical port through the target optical port, so that the exchange single board where the target optical port is located or the exchange single board where the optical port to be detected is used for detecting whether the connection between the optical port to be detected and the target optical port is correct or not according to the position information of the target optical port, that is, whether the connection between the optical port to be detected and the target optical port is correct or not can be detected through the exchange single board, the complexity of detecting the optical port connection is reduced, and the reliability of detecting the optical port connection is improved.

In an optional embodiment, the method further comprises:

when the exchange single board where the target optical port is located determines that the target optical port is connected with the optical port to be detected incorrectly, sending a prompt message carrying position information of an expected optical port corresponding to the target optical port or the optical port to be detected; or,

and when the switching single board where the target optical port is located determines that the connection between the target optical port and the optical port to be detected is correct, sending a link establishment request through the target optical port.

Here, the sending of the alarm message may be sending of a connection error message between the target optical port and the optical port to be detected in a command line manner, so as to display the connection error message between the target optical port and the optical port to be detected on a display interface of the user telnet cluster router. The sending of the warning message may also be directly sending a warning message to a user to inform that the connection between the target optical port and the optical port to be detected is wrong. The sending of the warning message may also be triggering of a set indicator light to light up so as to inform that the connection between the target optical port and the optical port to be detected is wrong. For example, suppose that a connection status indicator lamp is correspondingly arranged on each optical port on the switch board, and when the optical ports are correctly connected, the connection status indicator lamp corresponding to the optical port is not turned on; and when the connection of the light port is wrong, the connection state indicator lamp corresponding to the light port is lightened. The switching board where the target optical port is located sends a link establishment request through the target optical port, which can be understood as that the switching board where the target optical port is located sends a set large flow message to the optical port to be detected through the target optical port, so as to inform that the connection between the target optical port and the optical port to be detected is correct. The switch board where the target optical port is located sends a link establishment request through the target optical port, which may be regarded as controlling the optical cable link establishment between the target optical port and the optical port to be detected. And when the switching single board where the target optical port is located determines that the target optical port is connected with the optical port to be detected incorrectly, sending a prompt message carrying the position information of the expected optical port corresponding to the target optical port or the position information of the expected optical port corresponding to the optical port to be detected so as to inform a user of changing the connection between the optical ports according to the prompt message. In addition, when the switch board where the target optical port is located determines that the connection between the target optical port and the optical port to be detected is in error, the switch board does not send a link establishment request through the target optical port, and may be regarded as controlling the optical cable link between the target optical port and the optical port to be detected to reset, so as to avoid the situations of packet loss or service interruption after the optical cable link is successfully established due to the optical cable insertion error.

Therefore, when the target optical port and the optical port to be detected are connected in error, namely the optical cable is inserted in error, the optical cable is prompted to be inserted in error by sending out an alarm, a prompt message and the like, the prompt mode is visual, and the prompt effect is good. When the connection between the target optical port and the optical port to be detected is correct, namely the optical cable is not inserted in a wrong way, the optical cable link is controlled to be established, and when the connection between the target optical port and the optical port to be detected is wrong, namely the optical cable is inserted in a wrong way, the optical cable link is controlled to be reset, so that the situations of packet loss or service interruption after the optical cable link is established successfully due to the optical cable insertion in a wrong way are avoided, and the detection flexibility is improved.

Here, when the switch board where the optical port to be detected is located encapsulates the position information of the optical port to be detected to the set detection message or encodes the position information of the optical port to be detected, and sends the position information of the optical port to be detected to the target optical port through the optical port to be detected in a detection message or code stream manner, the switch board where the target optical port is located correspondingly analyzes the received detection message or decodes the code stream, thereby obtaining the position information of the optical port to be detected. Therefore, the interference of the external environment can be effectively avoided.
