The embodiment provides a network design. For the backup clock/time detection method, see Figure 1, including the following steps:

S101: Read at least one set of detection indicators for detecting clock/time of the network device, and the detection indicators include the following five groups: no clock/time synchronization indicator, no clock/time synchronization hop exceeding indicator, lack of active or standby clock Source configuration indicators, clock synchronization configured as ring indicators, and time synchronization indicators not enabled.

That is, the following at least one set of detection indicators for detecting the clock/time of the network device is read: the clock/time synchronization indicator, the clock/time synchronization hop count exceeding indicator, the lack of the active or standby clock source configuration indicator, The clock synchronization is configured as a ring indicator and the time synchronization indicator is not turned on.

Before the S101, the method further includes: setting the five sets of detection indicators mentioned above. The method of setting the detection indicator can be set as the default setting and/or according to the user operation. On the basis of the default setting, the user can also change the detection index according to actual needs, and the user can input the clock/time synchronization indicator and the clock. The time/synchronous hop count is exceeded, the primary or backup clock source configuration indicator is omitted, the clock synchronization is configured as a ring indicator, and the time synchronization indicator is not enabled. The clock/time detection indicators of the network devices of the entire network are pre-configured to ensure the detection index. The correctness.

Each group of detection indicators corresponds to detecting the clock/time configuration of different types of network devices. The clock/time synchronization indicator is not supported to detect whether the network device does not support clock/time synchronization. The clock/time synchronization hop count exceeds the standard indicator to detect the network device clock. Whether the time synchronization hop count is exceeded or not, the lack of the active or standby clock source configuration indicator corresponds to whether the network device is configured to detect whether the network device is missing the primary or backup clock source. The clock synchronization is configured as a ring indicator corresponding to detecting whether the network device clock synchronization is configured as a ring, not enabled. The time synchronization indicator corresponds to detecting whether the network device does not turn on time synchronization.

S102: Acquire detection parameters corresponding to each detection index, and detect detection parameters and corresponding detection indicators to generate detection results.

Each group of detection indicators corresponds to detecting the clock/time configuration of different types of network devices, and the detection of each group is independent and does not interfere with each other. When at least two sets of detection indicators are read, the detection parameters corresponding to the detection indexes are obtained, and the detection parameters and the corresponding detection indicators may be detected by any one of the following two methods:

Method 1: Obtain all the detection parameters, and test the detection parameters and the corresponding detection indicators by the group;

Manner 2: Obtain a set of detection parameters, and detect the detection parameters and the corresponding detection indicators; then acquire the next set of detection parameters, and detect the detection parameters and the corresponding detection indicators until all the detection indicators are detected and corresponding Detection parameters.

If the clock/time synchronization indicator is not supported and there is an optical connection, it is determined that the network device does not support clock/time synchronization.

Referring to FIG. 2, the specific judging process includes: determining whether the version of the network device belongs to a network device version that does not support clock/time synchronization; if yes, directly determining that the network device does not support clock/time synchronization, and is an abnormal state; if not, then If the board or port of the network device is not a board or port that does not support clock/time synchronization, the board or port of the network device is a board or port that does not support clock/time synchronization. If the board or port of the network device belongs to a network device or port that does not support clock/time synchronization, in order to judge the result more accurately, further determine whether the corresponding port has an optical connection configuration. If yes, determine the network. The device does not support clock/time synchronization and is in an abnormal state. If it does not exist, it is determined to be in a normal state.

It should be understood that when checking whether the network device does not support clock/time synchronization, it is checked that the network device does not support the detection indicators of the clock synchronization and the time synchronization, and the determination mechanism is the same, and in order to implement the clock/time configuration of the network device. Comprehensive inspection to ensure the stability of network services. In actual operation, it is necessary and necessary to check that network devices do not support clock synchronization and time synchronization. Clock synchronization is consistent in frequency, and time synchronization is frequency and phase preservation. Consistent, the specific judgment process is as follows:

When checking whether the network device does not support clock synchronization, the detection indicators include that the clock synchronization indicator is not supported, and the version, board, and port of the network device that does not support clock synchronization are obtained, and whether the version of the network device belongs to a network device that does not support clock synchronization is determined. Version; if yes, directly determine that the network device does not support clock synchronization, which is an abnormal state; if not, further determine the network device Whether the board or the port is a network device board or port that does not support clock synchronization; if the board or port of the network device does not belong to a network device board or port that does not support clock/time synchronization, it is determined to be in a normal state; The board or port of the device belongs to the network device board or port that does not support clock synchronization. To determine the result is more accurate, further determine whether the corresponding port has an optical connection configuration. If it exists, determine that the network device does not support clock synchronization. If it does not exist, it is judged to be in a normal state.

When checking whether the network device does not support time synchronization, the detection indicator includes not supporting the time synchronization indicator, obtaining the version, board, and port of the network device that does not support time synchronization, and determining whether the version of the network device belongs to a network device that does not support time synchronization. If yes, it is determined that the network device does not support time synchronization and is in an abnormal state; if not, it is further determined whether the board or port of the network device belongs to a network device board or port that does not support time synchronization; If the board or port is not a network device or a port that does not support time synchronization, it is determined to be in a normal state. If the board or port of the network device belongs to a network device board or port that does not support time synchronization, the result is more accurate. Further, it is determined whether the optical port has an optical connection configuration. If yes, it is determined that the network device does not support time synchronization, and is an abnormal state; if not, it is determined to be a normal state.

With the above solution, the clock/time configuration of the network device can be detected automatically, efficiently, and accurately: the network device does not support the clock/time synchronization function. Thereby saving manpower, improving the efficiency of network device clock/time detection, ensuring the accuracy of detection results and the stability of network services.

In an embodiment, when checking whether the clock/time synchronization hop count of the network device exceeds the standard, the detection indicator includes: a clock/time synchronization hop count exceeding the standard indicator; and the clock/time synchronization hop count exceeding the indicator may be set to clock/time synchronization. Hop count threshold. Obtaining detection parameters corresponding to each detection index, and detecting the detection parameter and the corresponding detection index, and generating the detection result includes at least one of the following methods:

Manner 1: Obtain the hop count of the local clock of the network device from the grandfather clock. When the hop count is greater than the clock/time synchronization hop exceeds the standard, determine that the time synchronization hop count of the network device exceeds the standard;

Manner 2: When the current synchronization timing source of the network device is the extracted Ethernet clock, obtain the hop count of the distance between the network device and the other network device; the current synchronization timing source of the other network device is the external clock, the internal clock, and the global positioning. System (GPS, Global Positioning System) clock or 1588 hours The current synchronous timing source of the clock or another network device is the extracted Ethernet clock, and the network device is farthest from the other network device; when the hop count is greater than the clock/time synchronization hop count exceeding the standard, the clock synchronization of the network device is determined. The number of hops exceeded the standard.

The specific judgment process of the above two methods includes:

Method 1: Refer to FIG. 3, determine whether the hop count of the local clock of the network device is greater than the time synchronization hop threshold, and if yes, determine that the time synchronization hop count of the network device exceeds the standard, and the abnormal state; if not, determine normal status. The distance from the local clock to the grandfather clock can be queried through the 1588 state.

Manner 2: Refer to Figure 4 to determine whether the current synchronization timing source of the network device is the extracted Ethernet clock. If not, it does not participate in the evaluation; if yes, it determines whether the network device can find the root node, and the root node includes the current synchronization timing source. Network device with clock, internal clock, GPS clock or 1588 clock;

If the root node is found, it is determined whether the hop count of the network device from the root node is greater than the threshold of the clock synchronization hop count. If yes, it is determined that the number of clock synchronization hops of the network device exceeds the standard, and is an abnormal state; if not, it is determined to be a normal state. ;

If the root node cannot be found, it is determined whether the hop count of the network device from the other network device is greater than the clock synchronization hop threshold, and the current synchronization timing source of the other network device is also the extracted Ethernet clock, and the network device is the most distant from the other network device. Far; if yes, it is determined that the number of clock synchronization hops of the network device exceeds the standard, and is an abnormal state; if not, it is determined to be a normal state.

It should be understood that the first method is to determine whether the time synchronization hop count of the network device exceeds the standard, and the second method is to determine whether the clock synchronization hop count of the network device exceeds the standard, in order to implement a comprehensive check of the network device clock/time configuration to ensure the network service. Stability, in actual operation, it is necessary and indispensable to check whether the number of clock synchronization hops of the network device exceeds the standard and whether the time synchronization hop count exceeds the standard.

With the above solution, the clock/time configuration of the network device can be detected automatically, efficiently, and accurately: the clock/time synchronization hop count exceeds the standard. Thereby saving manpower, improving the efficiency of network device clock/time detection, ensuring the accuracy of detection results and the stability of network services.

In one embodiment, when checking if the network device lacks an active or standby clock source configuration, The detection indicators include the lack of the active or standby clock source configuration indicators, and the lack of the active or standby clock source configuration indicators may include: the number of optical connections of the network device and the threshold number of clock sources configured for the corresponding optical connection port.

The threshold of the number of optical connections of the network device and the number of clock sources configured by the corresponding optical port includes the following two situations:

1. When the number of optical connections of the network device is less than or equal to 1, the threshold of the number of clock sources configured for the corresponding optical port is 1. The clock source here includes the Ethernet clock, the line pumping clock, or the branch clock. If the number of clock sources configured on the optical connection port of the network device is less than the threshold, it may be determined that the network device lacks an active or standby clock source configuration;

2. When the number of optical connections of the network device is greater than 1, the threshold of the number of clock sources configured for the corresponding optical port is 2, and the clock source here includes the extracted Ethernet clock, the line pumping clock, the branch clock, the external clock, and the GPS clock. Or 1588 clock, excluding the internal clock; in addition, if the number of clock sources configured by the optical connection port of the network device is less than the threshold, it may be determined that the network device lacks the active or standby clock source configuration.

Here, the extracted Ethernet clock (SyncE) means that the clock signal is extracted from the Ethernet line as the clock synchronization from the Ethernet line.

The Sync From E1 Line Clock refers to: extracting a clock signal from the E1 line as the system clock of the entire device (clock synchronization from E1 line).

The Sync From E1 branch clock means that the clock signal is extracted from the E1 signal input from the E1 port as the clock synchronization from the E1 branch.

Obtaining detection parameters corresponding to each detection index, and detecting the detection parameter and the corresponding detection index, and generating the detection result includes:

Obtaining the number of optical connections of the network device and the number of clock sources configured for the optical connection port of the network device;

When the number of optical connections is less than or equal to 1, the number of clock sources is less than 1, and the clock source includes the extracted Ethernet clock, the line pumping clock, or the tributary clock, or when the number of optical connections is greater than 1, the number of clock sources is less than 2, and the clock When the source does not include the internal clock, it is determined that the network device lacks the primary or backup clock source. Configuration.

Referring to FIG. 5, the specific judging process includes: determining whether the number of optical connections of the network device is greater than 1. If the number of optical connections of the network device is less than or equal to 1, determining whether the number of clock sources configured by the optical connection port of the network device is less than 1, The clock source includes an extracted Ethernet clock, a line pumping clock, or a branching clock; if yes, it is determined that the network device lacks an active or standby clock source configuration, and is in an abnormal state; if not, it is determined to be a normal state, and the normal state is The specific situation is as follows: if the number of optical connections of the network device is equal to 1, it is determined whether the number of clock sources configured by the optical connection port of the network device is 1, and the clock source includes an extracted Ethernet clock, a line pumping clock, or a branching clock; if yes, Then it is determined to be in a normal state.

If the number of optical connections of the network device is greater than 1, it is determined whether the number of clock sources configured by the optical connection port of the network device is less than 2. The clock source here includes the extracted Ethernet clock, the line drawing clock, the branch pumping clock, the external clock, and the GPS. The clock or 1588 clock does not include the internal clock; if so, it determines that the network device lacks the active or standby clock source configuration and is in an abnormal state; if not, it is determined to be in a normal state.

With the above solution, the clock/time configuration of the network device can be detected automatically, efficiently, and accurately: the primary or backup clock source configuration is missing. Thereby saving manpower, improving the efficiency of network device clock/time detection, ensuring the accuracy of detection results and the stability of network services.

In an embodiment, when detecting whether the network device clock synchronization configuration is looped, the detection indicator includes clock synchronization configured as a ring indicator, acquiring detection parameters corresponding to each detection indicator, and detecting the detection parameter and the corresponding detection indicator, The detection result includes: acquiring the version of the network device, the board, and the port. When the number of optical connections between the network device and the other network device is greater than 1, the network device and the other network device are configured to extract an Ethernet clock, and When it is determined that the clock source along the optical connection link forms a closed loop in the direction according to the version, the board, and the port of the network device, it is determined that the network device clock is synchronously configured into a ring.

Referring to FIG. 6, the specific judging process includes: judging whether the configuration of the network device is an extracted Ethernet clock, and if not, not participating in the evaluation, for example, if the network device is configured with a line drawing clock or a branch clock, it does not participate in the evaluation. . If the network device is configured with an Ethernet clock, determine whether the number of optical connections between the two network devices is greater than 1. If yes, determine the clock source along the optical connection link according to the version, board, and port of the network device. Whether a closed loop is formed in the direction, and if so, The clock of the network device is synchronously configured as a ring, which is an abnormal state; if not, it is determined to be a normal state. If the number of optical connections between the two network devices is not greater than 1, it is determined whether the number of optical connections between the two network devices is 1. If the number of optical connections between the two network devices is 1, according to the network device The version, the board, and the port determine whether the clock source along the optical link link forms a closed loop in the direction. If yes, it determines that it is in a normal state.

When the network device is in the optical connection state, it can determine which direction the clock source is drawn according to the version, board, and port of the network device. It should be noted that if there is only one optical connection between two network devices, if the clock source is configured to be mutually pumped, this case does not determine that the clock synchronization is configured as a ring, which is a normal state.

The mutual extraction refers to: the two devices are each other's system clock.

It should be understood that, for a network device configured with an extracted Ethernet clock, a directional tree is formed, and the corresponding clock configuration along the current tree structure is extracted back to the source network device, and then the clock of the corresponding network device is determined to be configured as a ring.

If the number of optical connections between the network device A and the network device B is greater than 1, the number of optical connections between the network device A and the network device B is greater than one; if the network device A and the network After the above rules check is applied between the devices B to configure clock synchronization for the ring, it is determined that the clock synchronization is configured as a ring. If the optical connection between the network device A and the network device B is directly performed, and the network device A and the network device B are also optically connected through the network device C, this situation also belongs to between the network device A and the network device B. The number of optical connections is greater than one. If the above rules are applied between the network device A and the network device B to check that the clock synchronization is configured as a ring, it is determined that the clock synchronization is configured as a ring. It should be understood that the number of optical connections between the network device A and the network device B is greater than one, and is not limited to the above two types. For example, the following is one of the modes: the network device A and the network device B pass through the network device. C is optically connected to form an optical connection link 1. The network device A and the network device B are also optically connected through the network device D to form an optical connection link 2.

With the above solution, the clock/time configuration of the network device can be detected automatically, efficiently, and accurately. Thereby saving manpower, improving the efficiency of network device clock/time detection, ensuring the accuracy of detection results and the stability of network services.

In an embodiment, when checking whether the network device does not enable the time synchronization function, the detection indicator includes an un-on time synchronization indicator, acquires detection parameters corresponding to each detection indicator, and detects the detection parameter and the corresponding detection indicator, The detection result includes: obtaining a time-period (PTP) time port configuration item of the network device. When the network device does not have a PTP time port configuration item, determining that the network device is not enabled for time synchronization.

Referring to FIG. 7 , the specific judging process includes: determining whether a network device has a PTP time port configuration item, and if not, determining that the network device does not turn on time synchronization, and is an abnormal state; if yes, determining that the device is in a normal state.

With the above solution, the clock/time configuration of the network device can be detected automatically, efficiently, and accurately: time synchronization is not enabled. Thereby saving manpower, improving the efficiency of network device clock/time detection, ensuring the accuracy of detection results and the stability of network services.

S103: Output the detection result.
