Description

Signal loss alarm message processing method and device, electronic equipment and readable medium
Technical Field
The present disclosure relates to the field of optical communication technologies, and in particular, to a method and an apparatus for processing a signal loss warning message, an electronic device, and a readable medium.
Background
The most popular Optical access Network technology at home and abroad at present is PON (Passive Optical Network), in the whole PON system, an OLT (Optical Line Terminal) is provided with a plurality of PON ports, each ONU (Optical Network Unit) accesses to the PON access system through the PON port of the OLT, and since each PON port can access a large number of ONUs, the workload of manually managing fault work orders is huge, so most of the existing NetWorks adopt a work order system to dispatch orders.
When LOSi (Loss Of Signal) alarm information Of more than two ONUs is detected under a certain PON interface, the LOSi alarm information is reported to a work order system, and the work order system can automatically dispatch a fault work order. The OLT reports DG alarm messages only when it detects that ONU signals are lost and receives a dyenggasp message from the ONU, but the current network has a certain number of defective ONUs and cannot report the dyenggasp message when power is off due to various reasons (for example, the ONU power adapters are not matched, or the commercial power is in an undervoltage state before power is off). If the ONU cannot report the DyingGasp message, when the ONU is powered off, the OLT can only detect the loss of the ONU signal but does not know the power failure of the ONU, and then an LOSi alarm message is reported to the work order system. Therefore, when a power failure occurs in a certain area, which causes a large number of ONUs to intensively power down but no PON interface signal is lost, if a plurality of defective ONUs exist in the power failure area, an OLT generates a lot alarm message of the plurality of ONUs, and a work order system may mistakenly dispatch a faulty work order, which causes a lot of waste of human resources when the situation is frequent.

The embodiment of the present disclosure provides a method for processing a signal loss warning message, as shown in fig. 1, the method for processing a signal loss warning message includes the following steps:
and 11, recording the generation time of the LOSi alarm message after the signal loss LOSi alarm message of the ONU corresponding to the PON interface is generated.
If the OLT detects that a signal of a certain ONU (e.g., the ith ONU) corresponding to a certain PON interface is lost, it generates an loi alarm message for the PON interface. In this embodiment of the present disclosure, i represents an identifier of an ONU corresponding to the PON interface. In this step, after the lois alarm message of the PON interface is generated, when the LOS escape function of the PON interface is turned on, the generation time of the lois alarm message is recorded. It should be noted that the LOS escape function is set for each PON interface of the OLT, and the escape function of each PON interface may be manually turned on or off.
And step 12, under the condition that the generation time of the LOSi alarm message falls into the currently opened escape time window, escaping the LOSi alarm message into a first DGi alarm message.
The escape described in the embodiment of the present disclosure means that the first DGi warning message is generated according to the LOSi warning message. It should be noted that the LOSi alarm message is still retained, but the LOSi alarm message is not reported, but the generated first DGi alarm message is reported.
The escape time window is a time period in which escape operation can be performed, and is defined by a start time and an end time, and the escape time window is a time period between the start time and the end time. And within the duration of the preset first threshold value X, when the number m of second DGi alarm messages in the DGi alarm record of the PON interface reaches a preset second threshold value N, opening an escape time window. The first threshold value X is smaller than the opening duration of the escape time window, that is, the start time of the escape time window is before the generation time of the first second DGi alarm message in the DGi alarm record of the PON interface, and the end time of the escape time window is after the generation time of the current second DGi alarm message in the DGi alarm record of the PON interface. When the end time is reached, the escape time window is closed. It should be noted that, the time for determining that the escape time window is opened is usually after the start time of the escape time window, and when it is determined that the escape time window is opened, the start time of the escape time window is traced back to the beginning, and the escape time window is opened.
The first second DGi warning message is the first second DGi warning message of the m second DGi warning messages in the DGi warning record. The second DGi warning message is a DGi warning message generated after the PON interface receives the power-down message sent by the ith ONU. That is, when the OLT detects that a signal of a certain ONU (e.g., the ith ONU) corresponding to a certain PON interface is lost and the PON interface receives a dyenggasp message sent by the ith ONU, the OLT generates a second DGi alarm message for the PON interface.
In this step, once the generation time of the LOSi alarm message is found to fall within the currently opened escape time window, the LOSi alarm message is escaped to the first DGi alarm message. The first DGi warning message and the second DGi warning message are both DGi warning messages, except that the first DGi warning message is an escape-generated DGi warning message, and the second DGi warning message is a DGi warning message generated based on a dyenggasp message sent by the ONU.
And step 13, reporting the first DGi alarm message.
In this step, the first DGi warning message is reported to the work order system, and the work order system is a functional module of the network management equipment. It should be noted that, the second DGi warning message is also reported to the work order system after being generated.
If the OLT generates a second DGi warning message for multiple times within the duration of the first threshold value X, which indicates that the ONU in a certain area may be powered down, in the escape time window, if other ONUs (failed ONUs) in the area are powered down and cannot send DyingGasp messages to the OLT, the OLT only detects that the ONU signals are lost, and the generated LOSi warning message (actually, the failed ONU is powered down at the moment) is possibly misinformed, so that the part of the LOSi warning message is escaped to the first DGi warning message and reported to a work order system, the condition of misassigning a fault work order can be avoided, and the accuracy of ONU power down judgment is improved.
According to the method for processing the signal loss alarm message, after the signal loss LOSi alarm message of the ONU corresponding to the PON interface is generated, the generation time of the LOSi alarm message is recorded; and under the condition that the generation time of the LOSi alarm message falls into a currently opened escape time window, escaping the LOSi alarm message into a first DGi alarm message, and reporting the first DGi alarm message, wherein when the number m of second DGi alarm messages in a DGi alarm record of the PON interface reaches a preset second threshold value N within the duration of a preset first threshold value X, the escape time window is opened, the starting time of the escape time window is before the generation time of a first second DGi alarm message in the DGi alarm record of the PON interface, and the ending time of the escape time window is after the generation time of the current second DGi alarm message in the DGi alarm record of the PON interface. Under the condition of centralized power failure in the area, the condition of misassignment fault work orders caused by reporting LOSi alarm messages when the defective ONU has power failure can be avoided, and the accuracy of ONU power failure judgment is improved.
In some embodiments, after recording the generation time of the LOSi alarm message, the loss of signal alarm message processing method further comprises the steps of: caching LOSi alarm information in a buffer area; and scanning the LOSi alarm message in the buffer area when the escape time window changes or a preset scanning period arrives.
The escape time window is changed by one or any combination of the following: the end time of the escape time window varies, and the start time and the end time of the escape time window vary.
In some embodiments, after recording the generation time of the LOSi alarm message (i.e., step 11), the loss of signal alarm message processing method may further include the steps of: and reporting the LOSi alarm message under the condition that the generation time of the LOSi alarm message does not fall into the currently opened escape time window and the generation time of the LOSi alarm message is longer than p times of a first threshold value X, wherein p is an integer larger than 1. That is to say, the lois alarm message that is not in the escape time window and whose generation duration is longer than pX is an overtime lois alarm message, and these overtime lois alarm messages are reported to the worksheet system, it should be noted that when reporting the overtime lois alarm message, the current time needs to be reported, instead of the generation time of the lois alarm message. In some embodiments, p may be 2.
In order to prevent the alarm after escape from remaining, the embodiment of the present disclosure further performs alarm recovery. Accordingly, in some embodiments, after the escaping of the LOSi alert message to the first DGi alert message (i.e., step 12), the method further comprises the steps of: and in response to receiving the LOSi recovery message, clearing the LOSi alarm message and the first DGi alarm message, and reporting the LOSi alarm recovery message and the first DGi alarm recovery message.
In the embodiment of the present disclosure, a DGi alarm record is maintained for each PON interface, and the DGi alarm record is used to record second DGi alarm messages and information thereof (including generation time), and in the DGi alarm record, the second DGi alarm messages are arranged in a positive order according to the generation time.
In some embodiments, the escape time window has a start time TN-X', the end time of the escape time window being Tstar+ X ', wherein X' = X + (T)N+Tstar)/X，TNFor the generation time, T, of the last second DGi alarm message in the DGi alarm record of the PON interfacestarAnd generating the generation time of the first second DGi alarm message in the DGi alarm record of the PON interface.
In the disclosed embodiment, the escape time window includes two types: the first type is a fixed escape time window, the second type is a sliding escape time window, the fixed escape time window means that the starting time and the ending time of the escape time window are not changed, and once the ending time is reached, the fixed escape time window is closed. Sliding the escape time window means that the end time of the escape time window can be varied, e.g. the end time can be adjusted backwards, i.e. the duration of the sliding escape time window is increased.
For different types of escape time windows, the opening conditions and the update process of the DGi alarm records are different, and the processing flows under the fixed escape time window and the sliding escape time window are described below.
When the type of the escape time window is pre-configured, and when the type of the escape time window is the first type (i.e. the fixed escape time window), in some embodiments, as shown in fig. 2, the method for processing a signal loss alarm message may further include the following steps:
step 21, after generating the second DGi alarm message of the ONU corresponding to the PON interface, responding to the escape time window that is not currently opened, and the generation time Tn of the second DGi alarm message and the generation time T of the first second DGi alarm message in the DGi alarm record of the PON interfacestarAnd if the difference is less than or equal to a first threshold value X, adding 1 to the number m of second DGi alarm messages in the DGi alarm records of the PON interface, and writing the second DGi alarm messages and the generation time Tn thereof into the DGi alarm records of the PON interface.
n is the number of the second DGi alarm message. In this step, once the second DGi notification is generatedThe alert message triggers a decision whether to update the escape time window and whether to update the DGi alert record. Under the condition that the escape time window is not opened currently, if the generation time Tn of the current second DGi alarm message and the generation time T of the first second DGi alarm message in the DGi alarm record are the same, the generation time of the current second DGi alarm message is not started, and the generation time T of the first second DGi alarm message in the DGi alarm record is not startedstarThe difference is smaller than or equal to the first threshold value X, which indicates that the interval between the current second DGi alarm message and the first second DGi alarm message in the DGi alarm record is small, and that more frequent power failure alarms occur within a current period of time, so that the second DGi alarm message and the number (i.e., m) of the frequently occurring power failure alarms need to be recorded, the number m of the second DGi alarm messages in the DGi alarm record of the PON interface is added by 1, and the second DGi alarm message and the generation time Tn thereof are written into the DGi alarm record of the PON interface.
Step 22, in response to m being equal to the second threshold N, generating a time T according to the first second DGi warning messagestarAnd the generation time Tn of the second DGi alarm message, calculating the starting time and the ending time of an escape time window, and opening the escape time window.
In this step, if m = N, it indicates that at least N second DGi alarms are generated within the duration X, and it may be considered that an ONU in an area corresponding to the PON interface has a power failure condition, for example, the ONU power adapter is not matched or the commercial power is in an under-voltage state before power failure, and in this case, an escape time window is determined and opened, so as to escape the LOSi alarm message falling into the escape time window, and avoid false alarm to the work order system.
In some embodiments, after generating the second DGi alarm message of the ONU corresponding to the PON interface, the method for processing a signal loss alarm message may further include the steps of: responding to the current escape time window without opening, and the generation time Tn of the second DGi alarm message and the generation time T of the first second DGi alarm message in the DGi alarm record of the PON interfacestarAnd if the difference is larger than the first threshold value X, clearing the DGi alarm record of the PON interface. That is, under the condition that no escape time window is opened currently, if the generation time Tn of the current second DGi alarm message and the first second DG in the DGi alarm record are the same, the first second DG in the DGi alarm record is updatedi generation time T of alarm messagestarIf the difference is greater than the first threshold value X, it means that the interval between the second DGi alarm message and the first second DGi alarm message in the DGi alarm record is large, and no more frequent power-down alarm occurs in the current period of time, so that the DGi alarm record of the PON interface is cleared without recording the second DGi alarm message and the number of power-down alarms that frequently occur, so as to make a new determination when generating the next second DGi alarm message.
In some embodiments, the method for processing a signal loss warning message may further include the steps of: after the second DGi alarm message of the ONU corresponding to the PON interface is generated, in response to the currently opened escape time window, the DGi alarm record of the PON interface is no longer updated, that is, the current second DGi alarm message and the generation time Tn are no longer written into the DGi alarm record of the PON interface. That is to say, when the second DGi alarm message is generated, once the escape time window is opened, the loi alarm message may be monitored according to the escape time window, and it is meaningless to record the current second DGi alarm message, so that the DGi alarm record of the PON interface is not updated any more, thereby saving storage resources and reducing data processing.
In some embodiments, the method for processing a signal loss warning message may further include the steps of: and responding to the arrival of the end time of the escape time window, closing the escape time window, and emptying the DGi alarm record of the PON interface.
For clarity of explaining the solution of the embodiment of the present invention, the following describes in detail the updating process of the fixed escape time window by a specific example with reference to fig. 3 and fig. 4. It should be noted that fig. 3 is a flow of updating the fixed escape time window when the escape time window is not opened. As shown in fig. 3, the update process of the fixed escape time window includes the following steps:
and 301, generating a second DGi alarm message of the ONU corresponding to the PON interface.
Step 302, judging whether a DGi alarm record of the PON interface has a second DGi alarm message, if so, executing step 304, otherwise, executing step 303.
In this step, if there is a second DGi alarm message in the DGi alarm record of the PON interface, further determining whether an escape time window is currently open (i.e., step 304 is executed); if there is no second DGi alarm message in the DGi alarm record of the PON interface, the second DGi alarm message generated in step 301 (i.e., the current second DGi alarm message) and the generation time of the second DGi alarm message are written into the DGi alarm record of the PON interface (i.e., step 303 is executed).
Step 303, writing the current second DGi alarm message and the generation time Tn into the DGi alarm record of the PON interface.
Because there is no second DGi alarm message in the DGi alarm record of the current PON interface, after the second DGi alarm message and the generation time Tn generated in step 301 are written into the DGi alarm record of the PON interface, tn is the generation time of the first second DGi alarm message in the DGi alarm record of the PON interface, so T is the generation time of the first second DGi alarm message in the DGi alarm record of the PON interfacestar＝Tn。
Step 304, determining whether there is an escape time window opened currently, if so, executing step 305, otherwise, executing step 306.
Step 305, the DGi alarm record of the PON interface is not updated any more.
And the second DGi alarm message generated in the process of opening the escape time window is not written into the DGi alarm record any more.
Step 306, determining the generation time Tn of the current second DGi alarm message and the generation time T of the first second DGi alarm message in the DGi alarm record of the PON interfacestarIf the difference is less than or equal to the first threshold value X, if yes, go to step 308, otherwise, go to step 307.
And 307, clearing the first second DGi alarm message and the generation time thereof in the DGi alarm record of the PON interface.
In this step, if Tn-Tstar>And X, if the explanation does not meet the opening condition of the escape time window, clearing the first second DGi alarm message and the generation time thereof in the DGi alarm record of the PON interface.
Step 308, adding 1 to the number m of the second DGi alarm messages in the DGi alarm record of the PON interface, and writing the second DGi alarm messages and the generation time Tn thereof into the DGi alarm record of the PON interface.
In this step, if Tn-TstarX, which indicates that the first opening condition of the escape time window is met, the DGi alarm record (including the number m of the second DGi alarm messages and the second DGi alarm messages) of the PON interface is updated, and it is further determined whether the second opening condition of the escape time window is met (i.e., step 309 is executed).
Step 309, determining whether the number m of the second DGi alarm messages in the DGi alarm record of the PON interface is equal to the second threshold N, if so, executing step 310, otherwise, ending the process.
In this step, if m = N, it indicates that the second opening condition of the escape time window is satisfied, and at this time, 2 conditions for opening the escape time window are satisfied, the escape time window is opened (i.e., step 310 is executed); if m is not equal to N, that is, m is less than N, it indicates that the second opening condition of the escape time window is not satisfied, the escape time window is not opened, and the updating process of the current fixed escape time window triggered by the second DGi alarm message generated this time is ended (the escape time window is not opened).
Step 310, generating time T according to the first second DGi alarm messagestarAnd the generation time Tn of the current second DGi alarm message, calculating the starting time and the ending time of the escape time window, and opening the escape time window.
And 311, when the end time of the escape time window is reached, closing the escape time window and clearing the DGi alarm record of the PON interface.
Referring to fig. 4, if the generation time of the current second DGi alarm message is Tn, the generation time T of the first second DGi alarm message in the DGi alarm record of the PON interface is TstarThe current second DGi alarm message is the last second DGi alarm message in the DGi alarm record of the PON interface, and the starting time of the escape time window is calculated to be T1 under the condition that two conditions of opening the escape time window are metN-X', the end time of the escape time window being Tstar+ X ', wherein X' = X + (T)N+Tstar)/X。
When the type of the escape time window is the second type (i.e. sliding escape time window), in some embodiments, as shown in fig. 5, the method for processing a loss of signal warning message may further include the following steps:
step 51, after generating the second DGi warning message of the ONU corresponding to the PON interface, responding to the currently opened escape time window, and the generation time Tn of the second DGi warning message and the generation time T of the (N-N + 1) th second DGi warning message in the DGi warning record of the PON interface(n-N+1)And writing the second DGi alarm message and the generation time Tn thereof into a DGi alarm record of the PON interface, and determining the (N-N + 1) th second DGi alarm message as a first second DGi alarm message.
In this step, once the second DGi alarm message is generated, the determination of whether to update the escape time window and whether to update the DGi alarm record is triggered. Under the condition that an escape time window is opened currently, if the generation time Tn of the current second DGi alarm message and the generation time T of the (N-N + 1) th second DGi alarm message in the DGi alarm record are the same, the generation time of the current second DGi alarm message is equal to the generation time Tn of the (N-N + 1) th second DGi alarm message in the DGi alarm record(n-N+1)The difference is smaller than or equal to the first threshold value X, which indicates that the interval between the second DGi alarm message and the (N-N + 1) th second DGi alarm message in the DGi alarm record is smaller, so that the current second DGi alarm message and the generation time Tn thereof are written into the DGi alarm record of the PON interface. Deleting the first second DGi alarm message and the generation time thereof in the DGi alarm record of the PON interface to use the TstarIs adjusted to T(n-N+1)。
And step 52, adjusting the end time of the escape time window according to the updated generation time of the first second DGi alarm message and the generation time Tn of the second DGi alarm message.
In this step, since T is already set in step 51starIs adjusted to T(n-N+1)And the generation time Tn of the second DGi alarm message has been written into the DGi alarm record, so in this step, according to the updated TstarAnd the current generation time Tn of the second DGi alarm message, and the end time of the escape time window is adjusted to be T(n-N+1)+ X', i.e. adjusting the end time of the escape time window backwards, thereby enabling a sliding adjustment of the escape time window.
In some embodiments, the method for processing a signal loss alarm message further comprises the following steps: and closing the escape time window in response to the arrival of the end time of the escape time window, and deleting the first second DGi alarm message and the generation time thereof in the DGi alarm record of the PON interface so as to reserve the latest (N-1) second DGi alarm messages in the DGi alarm record of the PON interface, so that whether the power failure phenomenon occurs or not can be judged for each subsequently generated second DGi alarm message, and the escape time window determined by the method is more accurate.
In some embodiments, the method for processing a signal loss warning message may further include the steps of: after generating the DGi alarm message of the ONU corresponding to the PON interface, responding to the condition that no escape time window is opened currently and the DGi alarm record of the PON interface is empty, writing the current second DGi alarm message and the generation time Tn thereof into the DGi alarm record of the PON interface, namely using the generation time Tn of the current second DGi alarm message as the generation time T of the first second DGi alarm message in the DGi alarm record of the PON interfacestar。
In some embodiments, the method for processing a signal loss warning message may further include the steps of: step 61, after generating the second DGi alarm message of the ONU corresponding to the PON interface, responding to the escape time window that is not currently opened, and the generation time Tn of the second DGi alarm message and the generation time T of the first second DGi alarm message in the DGi alarm record of the PON interfacestarThe difference is less than or equal to a first threshold value X, adding 1 to the number m of second DGi alarm messages in the DGi alarm records of the PON interface, and writing the second DGi alarm messages and the generation time Tn thereof into the DGi alarm records of the PON interface; step 62, in response to m being equal to the second threshold N, generating a time T according to the first second DGi warning messagestarAnd the generation time Tn of the current second DGi alarm message, calculating the starting time and the ending time of the escape time window, and opening the escape time window. That is, when the type of escape time window is the secondWhen the second DGi warning message is generated, the update process of the escape time window (i.e. steps 61-62) is the same as the update process of the escape time window of the first type (i.e. steps 21-22) in the case that there is no open escape time window, and is not described herein again.
For clarity of explaining the solution of the embodiment of the present invention, the following describes in detail the update process of the sliding escape time window by a specific example with reference to fig. 6a, fig. 6b and fig. 7. As shown in fig. 6a, the updating process of the sliding escape time window includes the following steps:
step 601, generating a second DGi warning message of the ONU corresponding to the PON interface.
Step 602, determining whether there is an escape time window opened currently, if yes, executing step 603, otherwise, executing step 606.
Step 603, determining the generation time Tn of the second DGi alarm message and the generation time T of the (N-N + 1) th second DGi alarm message in the DGi alarm record of the PON interface(n-N+1)If the difference is smaller than or equal to the first threshold value X, if yes, go to step 604, otherwise, end the process.
Step 604, writing the second DGi alarm message and the generation time Tn into the DGi alarm record of the PON interface, and writing the T into the alarm record of the PON interfacestarAdjusted to T(n-N+1)And adjusting the end time of the escape time window according to the updated generation time of the first second DGi alarm message and the generation time Tn of the second DGi alarm message.
n is the number of the second DGi warning message. In this step, the first second DGi alarm message and its generation time in the DGi alarm record of the PON interface are deleted to use TstarIs adjusted to T(n-N+1)And, adjusting the end time of the escape time window to T(n-N+1)+X’。
As shown in fig. 7, the generation time of the current second DGi alarm message is Tn, and after the second DGi alarm message is generated, it is determined that the escape time window a is opened, where Tn = TNThe escape time window A has a starting time TN-X', the end time of escape time window A being T1+ X', wherein，X’＝X+(TN+T1) and/X. If Tn-T(n-N+1)Less than or equal to X, writing the current second DGi alarm message and the generation time Tn thereof into the DGi alarm record of the PON interface, and deleting the first second DGi alarm message and the generation time thereof in the DGi alarm record of the PON interface so as to facilitate the TstarIs adjusted from T1 to T(n-N+1)Correspondingly, the end time of the escape time window A is adjusted to Tstar+ X' (i.e. T)(n-N+1)+ X ') to obtain an escape time window A ', i.e. the opening escape time window A ', the start time of which is unchanged and remains TN-X ', i.e. the escape time window a' is extended backwards with respect to the escape time window a.
Step 605, when the ending time of the escape time window is reached, closing the escape time window, and deleting the first second DGi alarm message and the generation time thereof in the DGi alarm record of the PON interface, so as to keep the latest (N-1) second DGi alarm messages in the DGi alarm record of the PON interface.
Steps 601-605 are the update procedure of the sliding escape time window when the current escape time window is opened. The following describes the process of opening the sliding escape time window when the current escape time window is not opened with reference to fig. 6 b. As shown in fig. 6b, the process includes the following steps:
step 606, determine whether the DGi alarm record of the PON interface is empty, if yes, execute step 608, otherwise, execute step 607.
Step 607, writing the current second DGi alarm message and the generation time Tn into the DGi alarm record of the PON interface.
Because there is no second DGi alarm message in the DGi alarm record of the current PON interface, after the second DGi alarm message generated in step 601 and the generation time Tn thereof are written into the DGi alarm record of the PON interface, tn is the first second DGi alarm message in the DGi alarm record of the PON interface, at this time, T is the first second DGi alarm message in the DGi alarm record of the PON interfacestar＝Tn。
Step 608, determining the generation time Tn of the current second DGi alarm message and the generation time T of the first second DGi alarm message in the DGi alarm record of the PON interfacestarWhether the difference isIf the value is less than or equal to the first threshold value X, step 610 is performed, otherwise, step 609 is performed.
Step 609, clear the first second DGi alarm message and the generation time thereof in the DGi alarm record of the PON interface.
In this step, if Tn-Tstar>And X, if the explanation does not meet the opening condition of the escape time window, clearing the first second DGi alarm message and the generation time thereof in the DGi alarm record of the PON interface.
Step 610, adding 1 to the number m of the second DGi alarm messages in the DGi alarm record of the PON interface, and writing the current second DGi alarm message and the generation time Tn thereof into the DGi alarm record of the PON interface.
In this step, if Tn-TstarX, which indicates that the first opening condition of the escape time window is met, the DGi alarm record of the PON interface is updated (including updating the number m of the second DGi alarm messages and the second DGi alarm messages), and it is further determined whether the second opening condition of the escape time window is met (i.e., step 611 is performed).
Step 611, whether the number m of the second DGi alarm messages in the DGi alarm record of the pon interface is equal to the second threshold N, if yes, step 612 is executed, otherwise, the process is ended.
In this step, if m = N, it indicates that the second opening condition of the escape time window is satisfied, and at this time, 2 conditions for opening the escape time window are all satisfied, the escape time window is opened (i.e., step 612 is executed); if m is not equal to N, namely m is less than N, the second opening condition of the escape time window is not met, the escape time window is not opened, and the updating process of the sliding escape time window triggered by the current second DGi alarm message is finished.
Step 612, generating time T according to the first second DGi alarm messagestarAnd the generation time Tn of the current second DGi alarm message, calculating the starting time and the ending time of the escape time window, opening the escape time window, and executing the step 605.
It should be noted that after the escape time window is opened, the opening time of the escape time window is monitored, and when the escape time window is openedEnd time T(n-N+1)And when + X' arrives, closing the escape time window, and deleting the first second DGi alarm message in the DGi alarm record of the PON interface and the generation time thereof so as to reserve the latest (N-1) second DGi alarm messages in the DGi alarm record of the PON interface.
For clearly explaining the scheme of the embodiment of the present disclosure, the following describes in detail the process of processing the loss of signal warning message according to the embodiment of the present disclosure by taking an example of a fixed escape time window and an example of a sliding escape time window as examples, respectively, with reference to fig. 8 and fig. 9.
FIG. 8 is an example of a fixed escape time window, as shown in FIG. 8, configured by the user: x is 3 seconds, N is 5, p =2. The OLT generates second DGi alarm messages each for 3 seconds, 3.2 seconds, 4.2 seconds, 4.5 seconds, 5.3 seconds, 5.6 seconds, and 7.2 seconds, and the DGi numbers n of the second DGi alarm messages are 1 to 7, respectively. If there is no escape time window initially, generate the first and the second DGi alarm information in 3 seconds, record T in the DGi alarm recordstarI.e. T1=3, subsequently when generating the 2 nd to 5 th second DGi warning messages, respectively, T2=3.2, T3=4.2, T4=4.5, and T5=5.3 are recorded. The generation time and T of the several second DGi alarm messagesstarThe difference is less than the first user-defined threshold X =3 seconds, and when the 5 th second DGi warning message DGi5 is generated, the number N of second DGi warning messages has reached the second user-defined threshold N =5, which satisfies the condition of opening the escape time window. The start time of the escape time window is calculated as T5-X ', the end time of the escape time window is calculated as T1+ X ', X ' =3+ (T5-T1)/3 =3.76, and thus the escape time window is 1.54 seconds to 6.76 seconds. At this time, the escape time window is opened, all the LOSi alarm messages stored in the buffer are scanned, and LOSi1 and LOSi2 with the generation time of the LOSi alarm message falling between 1.54 seconds and 6.76 seconds are escaped to be the first DGi alarm message. DGi6 is not recorded in the DGi alarm record because it is ignored within the escape time window. DGi7 is generated after the escape time window is closed and is therefore recorded in the DGi alarm record. LOSi3 generated outside the escape time window can not be escaped to be the first DGi alarm message, if the storage time of the LOSi3 in the buffer area reaches 6 seconds, the LOSi alarm is given according to the LOSiAnd reporting the disappearance timeout.
FIG. 9 is an example of a sliding escape time window, as shown in FIG. 9, user configured: x is 3 seconds, and N is 5. The OLT generates second DGi alarms for 3 seconds, 3.2 seconds, 4.2 seconds, 4.5 seconds, 5.3 seconds, 5.6 seconds, and 7.2 seconds, respectively, and the DGi numbers n of the second DGi alarm messages are 1 to 7, respectively. If there is no escape time window initially, generate the first and the second DGi alarm information in 3 seconds, record T in the DGi alarm recordstarI.e. T1=3, subsequently when generating the 2 nd-5 th second DGi warning message, T2=3.2, T3=4.2, T4=4.5, T5=5.3 are recorded, respectively. And starting an escape time window 1, scanning all the LOSi alarm messages stored in the buffer area, and escaping the LOSi1 and the LOSi2 into a first DGi alarm message in the same way as the starting judgment processing of the fixed escape window. When the 6 th second DGi warning message DGi6 is generated, because it is detected that the escape time window 1 is opened at this time, it is determined whether the difference between T6 and T2 is less than or equal to the first threshold X (X = 3) configured by the user, and it is found that T6 (5.6 s) -T2 (3.2 s) =2.4s is less than 3 seconds, therefore, the 6 th second DGi warning message and the generation time T6 thereof are written into the DGi warning record, and T6 is written into the DGi warning recordstartAdjusted to T2. The end time of the currently opened escape time window 1 is adjusted to T2+ (3 + (T6-T2)/3) =7 seconds, and at this time, the escape time window 1 becomes an escape time window 1', and the escape time window 1' is still in an open state. All the stored LOSi alarm messages in the buffer are scanned, and no new allowable LOSi alarm exists in the escape time window 1'. When the end time (7 s) of the escape time window 1 'is reached, the escape time window 1' is closed, then the DGi alarm records are updated again, the latest 4 times of second DGi alarm messages are reserved, namely the DGi2 corresponding to the T2 is deleted, DGi3, DGi4, DGi5 and DGi6 are reserved in the DGi alarm records, and at the moment, T is startedstartT3. When the 7 th second DGi alarm message DGi7 is generated, since the escape time window 1' is closed at this time, DGi3, DGi4, DGi5, DGi6, T are reserved in the DGi alarm recordsstartAt this time, T3 is present, and then T3 and T7 are compared, and T7 (7.2 s) -T3 (4.2 s) =3, which is not greater than the first threshold value of 3 seconds, so that a new escape time window 2 is opened, the start time of escape time window 2 is T7- (3 + (T7-T3)/3) =3.2 seconds, and the end time is T3 (4.2 s) + (3 + (T7 (7.2 s))-T3 (4.2 s))/3) =8.2 seconds. And scanning all the stored LOSi alarm messages in the buffer area, and transferring LOSi3 and LOSi4 into a first DGi alarm message.
In the embodiment of the disclosure, a DGi alarm record is maintained for each PON interface, where the DGi alarm record is used to record the latest m times (m is less than or equal to N) of second DGi alarm messages generated by the PON interface and the generation time of the second DGi alarm messages, and a time window (i.e., escape time window) is determined according to the generation time of the m times of second DGi alarm messages, and is used as a standard for intelligently determining whether an ONU has a power failure. And generating a second DGi alarm message and triggering the update of the DGi alarm record according to the opening state of the current escape time window, wherein the DGi alarm record can be maintained by adopting two strategies of a fixed time window and a sliding time window.
In the implementation of the disclosure, the LOS escape function can be set to be turned on or turned off, and a time period parameter (namely, a first threshold value X) before and after the LOSs of the LOSi and a standard (namely, a second threshold value N) for judging the frequent DGi alarm in the time period can be adjusted according to the actual situation, so that the accuracy of the OMU power-down judgment is improved. The scheme of the embodiment of the disclosure is flexible, the LOS escape function switch and related parameters can be configured according to the requirements of different users, whether the defective ONU has power failure or not can be accurately judged when the LOS escape function is started, the condition that a fault work order is wrongly dispatched is avoided, the requirements of different users are met, and the product competitiveness is improved.
