无源光网络告警检测方法及装置Passive optical network alarm detection method and device 技术领域Technical field
本发明涉及通信领域,具体而言,涉及一种无源光网络告警检测方法及装置。The present invention relates to the field of communications, and in particular to a passive optical network alarm detection method and apparatus.
背景技术Background technique
无源光网络(PON,简称为Passive Optical Network)技术目前已经是光接入网领域首选和主流技术,其在接入速率、带宽效率和分光比、全业务承载能力以及安全性方面都具有明显优势。PON技术还分为以太无源光网络(Ethernet Passive Optical Network,简称为EPON)和千兆无源光网络(Gigabit Passive Optical Network,简称为GPON),EPON技术由电气和电子工程师协会(Institute for Electrical and Electronic Engineers,简称为IEEE)的IEEE802.3 的第一英里以太网(Ethernet for the First Mile,简称为EFM)工作组进行标准化;GPON技术是由国际电信联盟-电信标准部(International Telecommunications Union-Telecommunications standardization sector,简称为ITU-T)提出并标准化。Passive Optical Network (PON) technology is currently the preferred and mainstream technology in the field of optical access networks. It has obvious access rate, bandwidth efficiency and split ratio, full service carrying capacity and security. Advantage. The PON technology is also divided into an Ethernet Passive Optical Network (EPON) and a Gigabit Passive Optical Network (GPON). The EPON technology is provided by the Institute of Electrical and Electronics Engineers (Institute for Electrical). And Electronic Engineers (referred to as IEEE) IEEE 802.3's Ethernet for the First Mile (EFM) working group standardization; GPON technology is the International Telecommunications Union-International Telecommunications Union- The Telecommunications standardization sector (referred to as ITU-T) is proposed and standardized.
典型的PON系统由局侧光纤线路终端(Optical Line Terminal,简称为OLT)、用户侧光纤网络单元(Optical Network Unit,简称为ONU)以及光分配网络(Optical Distribution Network,简称为ODN)组成,最常用的业务场景为光纤到户(Fiber To The Home,简称为FTTH)和光纤到楼(Fiber To The Building,简称为FTTB)。FTTH场景下,每个家庭部署一个ONU,为单个家庭提供数据、语音等业务;FTTB场景下,ONU部署在楼道里,然后通过线缆和用户的用户家庭网络(Home Network,简称为HN)相连接。运营商在无源PON网络的运维管理中,通常会有专门的网络监控中心,用于实时监控网络中设备的运行状态,如果设备有告警上报,通常会下发工单,安排相关的维护工程师排障。在FTTB的场景下ONU是部署在楼道里,用户是接触不到的。通常是由于ONU的电源模块等器件出故障而导致ONU断电的。而在FTTB场景下,一旦ONU断电,整栋楼的用户业务均会中断,会导致多用户的报障和投诉。因此在FTTB场景下,对于ONU掉电告警网络,网络监控中心会重点关注,一旦接到此类告警,会立即下发工单,安排相关的维护工程师处理的。A typical PON system is composed of an optical line terminal (OLT), an optical network unit (ONU), and an optical distribution network (ODN). Commonly used business scenarios are Fiber To The Home (FTTH) and Fiber To The Building (FTTB). In the FTTH scenario, each home deploys an ONU to provide data and voice services for a single home. In the FTTB scenario, the ONU is deployed in the corridor and then through the cable and the user's home network (Home Network, HN for short). connection. In the operation and maintenance management of the passive PON network, the operator usually has a dedicated network monitoring center to monitor the running status of the devices in the network in real time. If the device reports alarms, it usually sends out work orders and arranges related maintenance. The engineer is troubleshooting. In the FTTB scenario, the ONU is deployed in the corridor and is not accessible to users. Usually, the ONU is powered off due to a failure of the ONU's power module. In the FTTB scenario, once the ONU is powered off, the user service of the entire building will be interrupted, which will lead to multi-user reporting and complaints. Therefore, in the FTTB scenario, the network monitoring center will focus on the ONU power failure alarm network. Once such an alarm is received, the work order will be issued immediately and the relevant maintenance engineers will be arranged.
但在实际的运营维护中常常出现这样一个问题,在运营商的网络监控中心收到多个ONU断电的告警,在下发工单安排处理时,经常出现等维护工程师赶到现场时,发现是由于电力系统发生故障、整个小区停电而导致ONU断电。更有甚者,经常碰到电力系统调试,导致小区短时间,因此,对于FTTB场景下大量因小区断电而导致的ONU断电的告警的处理越来越成为运营商运维管理过程中的痛点。However, in actual operation and maintenance, such a problem often occurs. In the network monitoring center of the operator, multiple ONU power failure alarms are received. When the work order is scheduled, the maintenance engineers often arrive at the scene and find that The ONU is powered off due to a power system failure and a power outage in the entire cell. What's more, the power system is often debugged, resulting in a short time in the cell. Therefore, the handling of alarms for the ONU outage caused by the power outage of the cell in the FTTB scenario is becoming more and more important in the operation and maintenance management process of the operator. Pain points.
针对相关技术中,ONU断电的告警的处理不方便的问题,目前尚未提出有效的解决方案。In view of the inconvenience of handling the alarm of the ONU power failure in the related art, an effective solution has not been proposed yet.

下面结合优选实施例和实施方式对本发明进行详细说明。The invention will now be described in detail in conjunction with the preferred embodiments and embodiments.
本优选实施例提高了一种无源光网络系统(PON),应用于EPON或GPON网元设备(包括光线路终端OLT和光网络单元ONU)管理领域。它提供了一种无源光网络中因小区断电导致PON口业务中断的告警检测方法。The preferred embodiment improves a passive optical network system (PON) for use in the management of EPON or GPON network element devices, including optical line terminals OLT and optical network unit ONUs. It provides an alarm detection method for a PON port service interruption caused by a cell power failure in a passive optical network.
本优选实施例解决了运营商在无源光网络系统运维过程中的痛点,在发生小区断电的情况下,判断故障的原因,在上报告警给网络监控中心时,不在上报大量的ONU的断电告警,而是上报PON口级别的小区断电告警,使网络监控中心的运维人员一眼就能识别出小区断电。The preferred embodiment solves the pain point of the operator in the operation and maintenance process of the passive optical network system. When the cell is powered off, the cause of the fault is determined. When the alarm is reported to the network monitoring center, a large number of ONUs are not reported. The power-off alarm is reported to the cell power-off alarm at the PON port level, so that the operation and maintenance personnel of the network monitoring center can recognize the cell power-off at a glance.
本优选实施例是依据同一个PON口下接收到的不同ONU的断电告警,通过比较这些ONU断电告警的上报时间,再根据运营商部署ONU的特征总结出一套发现PON口小区断电告警的方法。The preferred embodiment is based on the power failure alarms of different ONUs received under the same PON port, and compares the reporting time of the ONU power failure alarms, and then finds a set of PON port community power failures according to the characteristics of the deployed ONUs of the operators. The method of alarming.
由于无源光网络的组网特征,其组网的结构是PON口下接分光器,分光器将主干光纤分离为多根分支光纤,每个分支光纤再接入ONU。而由于光信号强度等原因,一根主干光纤可分离的分支光纤数是有限的。在实际使用中通常一个PON口下可以接32到64个ONU,最大情况也不会超过256个ONU。因此处于成本考虑,同一个PON口下的ONU的物理位置不会太远,通常都在一个小区。即使是人口密集较低的小区,运营商也会将PON口下空闲的分支光纤预留给扩容用,而不是将光纤拉远到其它小区使用。Due to the networking characteristics of the passive optical network, the networking structure is that the PON port is connected to the optical splitter, and the optical splitter separates the trunk optical fiber into multiple branch optical fibers, and each branch optical fiber is connected to the ONU. The number of branch fibers that can be separated by one backbone fiber is limited due to optical signal strength and the like. In actual use, usually 32 to 64 ONUs can be connected under one PON port, and the maximum case is no more than 256 ONUs. Therefore, in terms of cost, the physical location of the ONU under the same PON port is not too far, usually in a cell. Even in a densely populated cell, the operator will reserve the idle branch fiber under the PON port for expansion, instead of pulling the fiber to other cells.
小区掉电告警的另外一个特征,发生小区掉电后,受影响的ONU都是在很短的时间内同时上报断电告警,因此如果OLT网元在很短的实际内(经验数据为01.秒)接收到同一个PON口下多个ONU的掉电告警,那么基本可以判断为该PON口下挂的ONU所在的小区发生了小区停电。Another feature of the cell power-down alarm is that after the cell is powered off, the affected ONUs report the power-off alarms in a short period of time. Therefore, if the OLT network element is in a short period of real (experience data is 01. Seconds) When receiving a power failure alarm for multiple ONUs under the same PON port, it is basically determined that a cell power failure occurs in the cell where the ONU connected to the PON port is located.
基于上述两个特征,可以根据这些信息来判断是否发生了小区断电告警。Based on the above two characteristics, it can be determined based on the information whether a cell power failure alarm has occurred.
在本优选实施例中,还提供了一种无源光网络中PON口小区断电告警的检测方法,该方法包括以下步骤:In the preferred embodiment, a method for detecting a power failure alarm of a PON port in a passive optical network is provided, and the method includes the following steps:
步骤1,网络的中ONU需要支持“掉电(Dying Gasp)”告警功能,即ONU在断电前的瞬间能给OLT网元上报断电告警信息。Step 1: The ONU of the network needs to support the "Dying Gasp" alarm function, that is, the ONU can report the power failure alarm information to the OLT network element immediately before the power failure.
步骤2,OLT网元接受到ONU上报的告警后,对于ONU断电不立即上报给网管,而是进入本地缓存队列。其它告警立即转发给网管。Step 2: After receiving the alarm reported by the ONU, the OLT does not immediately report the power to the NMS but enters the local cache queue. Other alarms are immediately forwarded to the NMS.
步骤3,取队列首部告警的发生时间,和当前检测时间比较,看时间差值是否达到设定时间片值,如果未达到设置的阈值,则休眠设定的休眠时间后,再次检测队列的首部和当前检测时间的差值是否达到设定的时间片值。如此循环,直到检测到时间差达到或超过设定的延时时间片值。Step 3: Take the time when the first alarm of the queue is taken, and compare with the current detection time to see if the time difference reaches the set time slice value. If the set threshold is not reached, the sleep time of the sleep is set again, and the first part of the queue is detected again. Whether the difference from the current detection time reaches the set time slice value. This cycle until it is detected that the time difference reaches or exceeds the set delay time slice value.
步骤4,标记当前队列首部告警的发生时间为T,标记步骤3中设定的时间片值为S。从 队列首部依次移除ONU断电告警记录并放入处理队列中,直到列首部的告警发生时间晚于T+S。在处理队列中对所有的ONU断电告警按照PON口的位置分组,同一个PON口下的ONU断电告警放在一个集合中,每个集合用PON口位置来标识。In step 4, the time when the current queue header alarm is marked is T, and the time slice value set in step 3 is marked as S. From The queue header first removes the ONU power failure alarm record and puts it into the processing queue until the alarm at the head of the column occurs later than T+S. In the processing queue, all ONU power-off alarms are grouped according to the location of the PON port, and the ONU power-off alarms under the same PON port are placed in a set, and each set is identified by the PON port position.
步骤5,对于步骤4中产生的每一个集合,计算该PON口下上报ONU断电告警的ONU数A,然后根据系统中保存的该处理时间片前此PON口下活动ONU数B,如果A=B,则上报PON口小区中断告警,不再上报每个ONU的断电告警;反之则和以前一样上报每个ONU的断电告警。Step 5: For each set generated in step 4, calculate the ONU number A of the ONU power failure alarm reported by the PON port, and then according to the processing time slice saved in the system, the number of active ONUs under the PON port is B, if A =B, the PON port community interrupt alarm is reported, and the power-off alarm of each ONU is not reported. Otherwise, the power-off alarm of each ONU is reported as before.
其中所述步骤1,还可扩展出如下步骤:In the step 1, the following steps can be extended:
步骤1所述的ONU上报“Dying Gasp”告警功能”,包括但不仅限于使用电容方式来在ONU断电前瞬间给OLT上报断电告警信息。The ONU reports the "Dying Gasp" alarm function, including but not limited to the use of a capacitor to report the power failure alarm to the OLT immediately before the ONU is powered off.
其中所述步骤2,还可扩展出如下步骤:In the step 2, the following steps can be extended:
步骤5所述的处理逻辑还包括一种特殊情况,PON口下只有这个在线ONU的情况,这种情况下因为告警误报的概率太高,不再采用前面的算法处理,而是继续上报ONU断电告警。The processing logic described in step 5 also includes a special case where only the online ONU is available under the PON port. In this case, because the probability of false alarms is too high, the previous algorithm is no longer used, but the ONU is continuously reported. Power failure alarm.
本优选实施例通过PON口下ONU的物理分布特征和发生小区断电情况下PON口下各个ONU上报断电的时序特征来检测小区断电。该方案创新性明显,目前现有技术和方案中未发现和本技术方案有雷同的。本优选实施例解决了其他技术无法解决的难题,可以发现那些通过其他技术手段很难检测出的PON口小区断电告警,进而解决了运营商在运维过程中的痛点。In the preferred embodiment, the cell power failure is detected by the physical distribution characteristics of the ONU under the PON port and the timing characteristics of the power failures reported by the ONUs under the PON port. The program is innovative, and it is not found in the prior art and the solution. The preferred embodiment solves the problem that cannot be solved by other technologies, and can find the PON port community power failure alarm that is difficult to detect by other technical means, thereby solving the pain point of the operator in the operation and maintenance process.
本发明还提供了另外一个实施例,该优选实施例是是通过PON口下ONU的物理位置分布特征和发生小区断电情况下,PON口下各个ONU上报断电的时序特征来检测小区断电。The present invention further provides another embodiment. The preferred embodiment detects the cell power failure by using the physical location distribution feature of the ONU under the PON port and the timing characteristics of the power failure of each ONU under the PON port when the cell is powered off. .
图3是根据本发明实施例的检测无源光网络中PON口小区断电告警的流程图,如图3所示,说明检了测PON口小区断电告警的过程。FIG. 3 is a flowchart of detecting a power failure alarm of a PON port cell in a passive optical network according to an embodiment of the present invention. As shown in FIG. 3, a process of detecting a power failure alarm of a PON port cell is illustrated.
步骤101:OLT网元监听ONU上报的告警;Step 101: The OLT network element monitors the alarm reported by the ONU.
OLT网元监听所有ONU上报的告警。其中需要保证ONU具备上报ONU断电告警的能力,即在ONU断电前的瞬间,ONU依靠电容或其它技术,保证可以给OLT网元上报断电告警。The OLT NE listens to alarms reported by all ONUs. The ONU needs to ensure that the ONU has the ability to report the ONU power failure alarm. That is, the ONU relies on the capacitor or other technology to ensure that the OLT network element can report the power failure alarm.
步骤102:OLT接受到告警后判断告警的类别;Step 102: After the OLT receives the alarm, determine the type of the alarm.
OLT网元接受到ONU上报的告警后,判断是否是ONU断电告警,如果是普通的非ONU断电的告警,则转到步骤110处理;如果是ONU断电告警,则转到步骤103。After receiving the alarm reported by the ONU, the OLT determines whether it is an ONU power failure alarm. If it is an ordinary non-ONU power failure alarm, go to step 110; if it is an ONU power failure alarm, go to step 103.
步骤103:将ONU断电告警加入缓存队列;Step 103: Add an ONU power failure alarm to the cache queue.
创建一个先进先出(First Input First Output,简称为FIFO)队列,将ONU断电告警根据告警的上报时间依次加入到队列中。因为是先进先出队列,队列首部的告警发生时间最早,队列尾部的告警发生时间最晚。 A first-in first-out (FIFO) queue is created, and the ONU power-off alarms are added to the queue according to the alarm reporting time. Because it is a FIFO queue, the alarm at the head of the queue is the earliest, and the alarm at the end of the queue occurs at the latest.
步骤104:循环检查队列首告警的发生时间和当前检测时间的差值是否达到设置的阈值;Step 104: cyclically check whether the difference between the occurrence time of the first alarm of the queue and the current detection time reaches a set threshold;
获取缓存队列首部告警的发生时间,计算和当前检测时间差是否达到设置的处理时间片阈值。如果时间差没有达到阈值,则转到步骤105;如果时间差达到或超过阈值,则转到步骤106。Obtain the time when the buffer queue header alarm occurs, and calculate whether the current detection time difference reaches the set processing time slice threshold. If the time difference does not reach the threshold, then go to step 105; if the time difference reaches or exceeds the threshold, go to step 106.
根据大量实验室数据,处理时间片阈值设置为0.1秒比较合适。进一步的为了保证在实际工程使用中本检测方法的准确性,此阈值保存在配置文件中,在实际工程中,可以根据现场的实际情况来调节。Based on a large amount of laboratory data, it is appropriate to set the processing time slice threshold to 0.1 second. Further, in order to ensure the accuracy of the detection method in actual engineering use, the threshold value is saved in the configuration file, and in actual engineering, it can be adjusted according to the actual situation on site.
步骤105:检测进程休眠给定时间;Step 105: Detect that the process sleeps for a given time;
在步骤104中,如果检查到队列首尾的时间差小于设定的阈值,则休眠给定的时间。In step 104, if it is checked that the time difference between the beginning and the end of the queue is less than the set threshold, then the given time is hibernated.
根据大量实验室数据,检测进程休眠时间为处理时间片阈值的三分之一到一半之间比较合适。进一步的为了保证在实际工程使用中本检测方法的准确性,此休眠时间保存在配置文件中,在实际工程中,可以根据现场的实际情况来调节。Based on a large amount of laboratory data, it is appropriate to detect that the process sleep time is between one-third and one-half of the processing time slice threshold. Further, in order to ensure the accuracy of the detection method in actual engineering use, the sleep time is saved in the configuration file, and in actual engineering, it can be adjusted according to the actual situation on site.
步骤106:将ONU断电告警移入处理队列;Step 106: Move the ONU power failure alarm into the processing queue;
将步骤104中缓存队列首部的ONU断电告警的发生时间记为A,处理时间片阈值记为B,则依次查询缓存队列首部的ONU断电告警记录,并标记此记录的告警发生时间为T。如果A+B>=T,则将此告警缓存队列首部移除,并加入到处理队列中。依次处理缓存队列的当前首部记录,直到不满足上述判断条件。The time when the ONU power-off alarm of the buffer queue header in step 104 is recorded as A, and the processing time slice threshold is recorded as B, then the ONU power-off alarm record of the cache queue header is sequentially queried, and the alarm occurrence time of this record is marked as T. . If A+B>=T, the alarm cache queue header is removed and added to the processing queue. The current header record of the cache queue is processed in sequence until the above judgment condition is not satisfied.
步骤107:将处理队列内的告警按照ONU所在的PON分组;Step 107: The alarms in the processing queue are grouped according to the PON where the ONU is located;
将处理队列内的ONU按照ONU所属的PON口进行分组,每一个PON口为一个分组。对处理队列内的PON口分组依次处理,直到所有的PON口都被处理完。每个PON的处理逻辑,如步骤108所示。The ONUs in the processing queue are grouped according to the PON port to which the ONU belongs, and each PON port is a packet. The PON port grouping in the processing queue is processed sequentially until all PON ports are processed. The processing logic for each PON is as shown in step 108.
步骤108:判断分组中是否只有一个ONU;Step 108: Determine whether there is only one ONU in the packet;
对于每一个PON口分组,首先判断是否为特殊情况,即PON口下只有一个ONU。如果PON口分组内只有一个ONU,则转到步骤110;如果PON口内ONU的数目大于1,则转到步骤109。For each PON port grouping, first determine whether it is a special case, that is, there is only one ONU under the PON port. If there is only one ONU in the PON port packet, go to step 110; if the number of ONUs in the PON port is greater than 1, go to step 109.
步骤109:判断是否为PON口小区断电告警;Step 109: Determine whether it is a PON port cell power failure alarm;
将PON口分组内的ONU总数,记为A,然后从系统中查询该处理时间片前该PON口下在线ONU数,记为B,如果A=B,则说明PON口下在线ONU在一个处理时间片内同时断电,则判断为PON口小区断电,转入步骤110;否则转入步骤110。The total number of ONUs in the PON port group is recorded as A, and then the number of online ONUs under the PON port before the processing time slice is queried from the system, which is recorded as B. If A=B, the online ONU under the PON port is processed in one process. If the power is off during the time slice, it is determined that the PON port cell is powered off, and the process proceeds to step 110; otherwise, the process proceeds to step 110.
步骤110:非PON口小区断电告警,直接将原告警转发给网管;Step 110: The non-PON port power failure alarm directly forwards the original alarm to the network management.
对于非PON口小区断电的普通情况,直接将原来ONU上报的告警原样转发给网管即可。 For the normal situation that the non-PON port is powered off, the alarm reported by the original ONU can be directly forwarded to the NMS.
步骤111:丢弃ONU断电告警;Step 111: Discard the ONU power failure alarm;
对于发生PON口小区断电告警的情况,需要进行告警抑制处理。需要将此PON口下各个ONU上报的ONU断电告警丢弃。In the case of a PON port cell power failure alarm, alarm suppression processing is required. You need to discard the ONU power failure alarm reported by each ONU under the PON port.
步骤112:上报PON口小区断电告警给网管;Step 112: Reporting a power failure alarm of the PON port to the network management system;
由OLT网元生成新的PON口小区断电告警,并将此告警上报给网管。A new PON port cell power failure alarm is generated by the OLT network element, and the alarm is reported to the network management system.
