Y.1731协议作为以太网的操作、 管理与维护（ Operations, Administration and Maintenance , OAM )协议， 定义了一系列测量丟包、 时延、 时延抖动的 方法， 使得运营商可以实时获取网络的真实性能数据， 快速诊断网络性能问 题， 也是提供给用户业务等级协议（Service Level Agreement, SLA )的有效 保证。  As an operation, administration, and maintenance (OAM) protocol of the Ethernet, the Y.1731 protocol defines a series of methods for measuring packet loss, delay, and delay jitter, so that operators can obtain the real network in real time. Performance data, rapid diagnosis of network performance issues, is also an effective guarantee for providing users with Service Level Agreements (SLAs).
Y.1731协议解决了以太组网点到点 (Point to Point , Ρ2Ρ)的性能测量问题。 对于按照 Y.1731 协议监控的网络， 可能会部署上千甚至上万的监控点。 对 于点到多点 (Point to Multipoint, P2MP)场景， Y.1731协议仅能够在众多点中 选取一个监控点。 为了解决以太网 P2MP组网的多点同时性能监控的问题， 所有的点都可以发起监控， 监控规模将会扩大 200倍以上。 因此， 目前网络 性能测量的配置复杂度、 工作量以及采集规模都比较大， 影响网络性能测量 的效率。 发明内容  The Y.1731 protocol solves the performance measurement problem of Ethernet point-to-point (Point to Point, Ρ2Ρ). For networks monitored according to the Y.1731 protocol, thousands or even tens of thousands of monitoring points may be deployed. For point-to-multipoint (P2MP) scenarios, the Y.1731 protocol can only select one monitoring point among a large number of points. In order to solve the problem of multi-point simultaneous performance monitoring of Ethernet P2MP networking, all points can be monitored and the monitoring scale will be expanded by more than 200 times. Therefore, the configuration complexity, workload, and acquisition scale of network performance measurement are relatively large, which affects the efficiency of network performance measurement.

在本发明实施例中， 源端和宿端为进行网络性能测量的网元， 应理解， 网元也可以表述为网元设备， 源端也可以表述为源端设备， 宿端也可以表述 为宿端设备。  In the embodiment of the present invention, the source end and the sink end are network elements for performing network performance measurement. It should be understood that the network element may also be expressed as a network element device, and the source end may also be expressed as a source end device, and the sink end may also be expressed as The sink device.

In the prior art, the user needs to configure the measurement configuration parameters. Therefore, the user needs to understand the Y.1731 protocol details and configure the user. The operation is complicated, the steps are many, and the error is easy, so the measurement efficiency is low.

For example, the network management device can configure the measurement configuration parameters to the source end and the sink end through a Simple Network Management Protocol (SNMP) or a Network Configuration Protocol (NETCONF). The source and sink perform network performance measurements based on the at least one measurement configuration parameter. The network management device can configure all measurement configuration parameters required for network performance measurement on the source and the sink. You can also configure only some measurement configuration parameters. When the network management device only configures some measurement configuration parameters, other measurement configuration parameters can be used according to the existing technology.

In this way, the configuration parameters are configured by the network management device, and the user does not need to input the measurement configuration parameter to implement performance monitoring.

The same measurement instance is allocated to ensure the MEP ID and RMEP of the source end of a measurement instance. The ID is matched with the MEP ID and the RMEP ID of the sink. That is, the MEP ID of the source is equal to the RMEP ID of the sink, and the RMEP ID of the source is equal to the MEP ID of the sink. Specifically, the network management device selects the MEP ID of the source end according to the port identifier and the VLAN ID of the source end configured by the user, and selects the MEP ID of the source end according to the port identifier and the VLAN ID of the sink configured by the user. Select the sink MEP ID, that is, the source RMEP ID, within the corresponding MEP ID range.

在本实施例中， 网管设备可以确定源端的 RMEP MAC地址或宿端的 In this embodiment, the network management device can determine the RMEP MAC address or the sink end of the source end.

若该源端的 MEP监控 UNI , 则确定该源端的 MEP方向为上；  If the MEP of the source end monitors the UNI, the MEP direction of the source end is determined to be upper;
若该源端的 MEP监控 NNI , 则确定该源端的 MEP方向为下。  If the MEP of the source monitors the NNI, the MEP direction of the source is determined to be lower.
在本实施例中， 网管设备确定源端的 MEP方向。 具体地， 如图 4所示： 对于源端的 MEP方向，  In this embodiment, the network management device determines the MEP direction of the source end. Specifically, as shown in Figure 4: For the MEP direction at the source end,
如果 MEP监控 UNI , 则方向为上（ up );  If the MEP monitors UNI, the direction is up (up);
如果 MEP监控 NNI, 则方向为下 （down )。  If the MEP monitors the NNI, the direction is down.
在本发明实施例中， 可选地， S110包括：  In the embodiment of the present invention, optionally, S110 includes:
若该宿端为 OLT, 该宿端的 MEP监控 UNI, 在该宿端的对端为 ONU 时确定该宿端的 MEP方向为下， 在该宿端的对端为路由器时确定该宿端的 MEP方向为上；  If the sink is an OLT, the MEP of the sink monitors the UNI. When the peer end of the sink is an ONU, the MEP direction of the sink is determined to be lower. When the peer end of the sink is a router, the MEP direction of the sink is determined to be upper;
若该宿端为 OLT, 该宿端的 MEP监控 NNI, 在该宿端的对端为 ONU 时确定该宿端的 MEP方向为上， 在该宿端的对端为路由器时确定该宿端的 MEP方向为下；  If the sink is an OLT, the MEP of the sink monitors the NNI.

若该宿端为路由器， 则确定该宿端的 MEP方向为上。  If the sink is a router, determine that the MEP direction of the sink is up.
在本实施例中， 网管设备确定宿端的 MEP方向。 具体地， 如图 4所示： 对于宿端的 MEP方向，  In this embodiment, the network management device determines the MEP direction of the sink. Specifically, as shown in Figure 4: For the MEP direction of the sink,
宿端为 OLT时， 如果 MEP监控 UNI， 对端是 ONU , 则方向为 down , 对端是路由器（CX_4 ), 则方向为 up; 如果 MEP监控 NNI, 对端是 ONU, 则方向 UP, 对端是路由器 (CX_4), 贝1 J方向 down; When the sink is the OLT, if the MEP monitors the UNI, the peer is the ONU, the direction is down, and the peer is the router (CX_4), the direction is up; If the MEP monitors the NNI, the peer is the ONU, the direction is UP, the peer is the router (CX_4), and the shell 1 J direction is down;
宿端为路由器（CX_4 ) 时， 固定方向为 UP。  When the sink is a router (CX_4), the fixed direction is UP.
在本发明实施例中， 可选地， S110包括：  In the embodiment of the present invention, optionally, S110 includes:
该网管设备确定该源端的主动 /被动参数为被动。  The network management device determines that the active/passive parameter of the source is passive.
在本实施例中，网管设备确定源端的主动 /被动参数。在单端性能测量中， 被动端收到性能测量报文后不把本地计数数据返回给主动端。 即被动端收到 测量报文后直接计算性能数据。在本发明实施例中，网管设备默认源端被动， 宿端主动。  In this embodiment, the network management device determines the active/passive parameters of the source. In single-ended performance measurement, the passive end does not return the local count data to the active end after receiving the performance measurement message. That is, the passive end directly calculates the performance data after receiving the measurement message. In the embodiment of the present invention, the default network source device is passive and the sink terminal is active.
在本发明实施例中， 可选地， 该方法 100还包括：  In the embodiment of the present invention, optionally, the method 100 further includes:
在点到多点场景下， 该网管设备向该源端发送 update-backward-mac命 令，以使该源端根据该 update-backward-mac命令选择用户业务 MAC地址作 为测量配置参数中的该源端的 backward MAC地址。  In a point-to-multipoint scenario, the network management device sends an update-backward-mac command to the source device, so that the source device selects the user service MAC address as the source of the measurement configuration parameter according to the update-backward-mac command. Backward MAC address.
Backward MAC是指定 MEP的背向侧用户业务报文的 MAC, 比如 OLT 与 MxU组成的测量实例中， MxU的 backward MAC为 MxU下挂用户的业 务报文 MAC。  The Backward MAC address is the MAC address of the user service packet of the MEP. For example, in the measurement instance of the OLT and the MxU, the backward MAC address of the MxU is the service packet MAC of the MxU.
由于测量对象是管道中的报文， 点到点场景 （即 1: 1场景） 下性能测量 不需要区分， 因此不输入 backward MAC。 点到多点场景（即 N:l场景)下， 源端 MxU的 backward MAC由 MxU默认选择一个用户业务 MAC即可， 这 个功能就是设备上支持的 update-backward-mac功能。 也就是说， 该网管设 备向源端发送 update-backward-mac命令, 源端才艮据该 update-backward-mac 命令选择用户业务 MAC作为源端 backward MAC。例如，如图 5所示， MxU 在指定用户端口上自动选择一个学习到的业务 MAC地址， 比如个人计算机 ( Personal Computer, PC ) 的 MAC地址， 作为源端 backward MAC。  Since the measurement object is a message in the pipe, the performance measurement under the point-to-point scenario (ie 1: 1 scene) does not need to be distinguished, so the backward MAC is not input. In the point-to-multipoint scenario (that is, the N:l scenario), the backward MAC of the source MxU is selected by the MxU by default. This function is the update-backward-mac function supported by the device. That is, the network management device sends the update-backward-mac command to the source, and the source device selects the user service MAC as the source backward MAC according to the update-backward-mac command. For example, as shown in Figure 5, the MxU automatically selects a learned service MAC address on the designated user port, such as the MAC address of a Personal Computer (PC), as the source backward MAC.
在本发明实施例中， 网管设备自动配置测量配置参数， 因此不需要用户 再输入相应的测量配置参数， 便于快速部署测量实例。  In the embodiment of the present invention, the network management device automatically configures measurement configuration parameters, so the user does not need to input corresponding measurement configuration parameters, which facilitates rapid deployment of measurement instances.
因此， 本发明实施例的网络性能测量的方法， 通过网管设备确定测量配 置参数， 可以减少用户的配置操作， 能够实现网络性能测量的快速部署， 从 而能够提高网络性能测量的效率。  Therefore, the method for measuring the network performance of the embodiment of the present invention can determine the configuration configuration parameters of the network management device, thereby reducing the configuration operation of the user, enabling rapid deployment of network performance measurement, thereby improving the efficiency of network performance measurement.
图 6示出了根据本发明另一实施例的网络性能测量的方法 600的示意性 流程图。 如图 6所示， 该方法 600包括： S610, 网元设备进行网络性能测量， 得到网络性能测量的原始数据；FIG. 6 shows a schematic flow diagram of a method 600 of network performance measurement in accordance with another embodiment of the present invention. As shown in FIG. 6, the method 600 includes: S610, the network element device performs network performance measurement, and obtains original data of network performance measurement;
S620, 该网元设备存储该原始数据， 以便于网管设备从该网元设备实时 获取该原始数据以进行实时监控； 并且， S620, the network element device stores the original data, so that the network management device obtains the original data from the network element device in real time for real-time monitoring;
S630, 该网元设备按照统计周期处理该原始数据， 存储按照统计周期处 理后的数据， 以便于该网管设备按照监控周期从该网元设备获取该按照统计 周期处理后的数据以进行周期监控。  S630, the network element device processes the original data according to a statistical period, and stores the data processed according to the statistical period, so that the network management device obtains the data processed according to the statistical period from the network element device according to the monitoring period for periodic monitoring.
目前网络性能测量的数据采集量比较大， 数据传输和处理的开销比较 高， 影响网络性能监控的效率。 在本发明实施例中， 网元设备在进行网络性 能测量， 获取网络性能测量的原始数据时， 一方面， 存储该原始数据， 另一 方面， 按照统计周期处理该原始数据并存储按照统计周期处理后的数据； 这 样， 网管设备可以按照监控周期从该网元设备获取该按照统计周期处理后的 数据以进行周期监控， 或者， 该网管设备可以从该网元设备实时获取该原始 数据以进行实时监控。 也就是说， 网元设备在进行网络性能测量时， 存储两 份数据， 一份是原始数据， 另一份是网元设备按照统计周期处理后的数据。 网管设备在进行周期监控时，按照监控周期从网元设备获取按照统计周期处 理后的数据， 在进行实时监控时， 从网元设备实时获取原始数据。  At present, the data collection of network performance measurement is relatively large, and the overhead of data transmission and processing is relatively high, which affects the efficiency of network performance monitoring. In the embodiment of the present invention, when the network element device performs network performance measurement to obtain the original data of the network performance measurement, on the one hand, the original data is stored, and on the other hand, the original data is processed according to a statistical period and stored according to a statistical period. After the data is collected, the network management device can obtain the data processed according to the statistical period from the network element device for periodic monitoring according to the monitoring period, or the network management device can obtain the original data from the network element device in real time for real-time monitoring. monitor. That is to say, when the network element device performs network performance measurement, it stores two pieces of data, one is the original data, and the other is the data processed by the network element device according to the statistical period. When the network management device performs periodic monitoring, it obtains data processed according to the statistical period from the network element device according to the monitoring period. When real-time monitoring is performed, the original data is obtained from the network element device in real time.
由于网元设备先按照统计周期对原始数据进行了处理， 网管设备在进行 周期监控时， 获取的数据量降低， 因此数据传输和处理的压力降低。 这样， 可以通过周期监控进行持续不断的业务质量监控， 对网络进行主动监控， 分 析网络业务质量历史趋势， 回顾网络质量故障原因等。  Since the network element device first processes the original data according to the statistical period, when the network management device performs cycle monitoring, the amount of data acquired is reduced, so the pressure of data transmission and processing is reduced. In this way, continuous monitoring of service quality can be performed through periodic monitoring, active monitoring of the network, analysis of historical trends in network service quality, and review of network quality failure causes.
另一方面， 对于已经识别或者怀疑业务管道质量问题， 对于该业务管道 可以发起实时监控， 以便高频度的获取最新的业务测量数据。 这种情况下， 网管设备可以从网元设备实时获取原始数据， 以给客户提供实时的业务质量 数据， 以便进行精确故障点捕捉， 辅助故障定位。  On the other hand, for the problem of the quality of the service pipeline that has been identified or suspected, real-time monitoring can be initiated for the service pipeline to obtain the latest service measurement data at a high frequency. In this case, the network management device can obtain the original data from the network element device in real time to provide real-time service quality data to the customer for accurate fault point capture and auxiliary fault location.
因此， 本发明实施例的网络性能测量的方法， 通过网元设备存储网络性 能测量的原始数据和按照统计周期处理后的数据， 网管设备可以获取按照统 计周期处理后的数据以进行周期监控， 获取原始数据以进行实时监控， 因而 可以降低传输数据量， 降低网管设备集中处理压力， 从而能够提高网络性能 测量的效率。  Therefore, in the network performance measurement method of the embodiment of the present invention, the network element device can store the data processed according to the statistical period to perform periodic monitoring and acquisition by using the network element device to store the original data of the network performance measurement and the data processed according to the statistical period. The raw data is monitored in real time, so that the amount of data transmitted can be reduced, and the centralized processing pressure of the network management equipment can be reduced, thereby improving the efficiency of network performance measurement.
在本发明实施例中， 可选地， 该网元设备存储该原始数据， 包括： 该网元设备将该原始数据存储为 MIB形式。 可选地， 该网元设备存储按照统计周期处理后的数据， 包括： In the embodiment of the present invention, optionally, the network element device stores the original data, including: the network element device stores the original data in an MIB format. Optionally, the network element device stores data processed according to a statistical period, including:
该网元设备将该按照统计周期处理后的数据存储为文本形式。  The network element device stores the data processed according to the statistical period as a text form.
具体而言， 网元设备测得原始数据后， 一方面， 将该原始数据存储为 Specifically, after the network element device measures the original data, on the one hand, the original data is stored as
MIB形式， 即 SNMP MIB形式， 不进行处理。 另一方面， 网元设备按照统 计周期对原始数据进行处理， 将处理后的数据存储为文本形式， 其中， 对原 始数据进行的处理具体可以是对原始数据进行加工，和 /或对原始数据进行计 算，和 /或对原始数据进行统计等。这样网元设备分担了一部分的数据处理工 作量， 可以降低网管设备集中处理的工作量。 The MIB form, that is, the SNMP MIB form, is not processed. On the other hand, the network element device processes the original data according to the statistical period, and stores the processed data in a text form, wherein the processing of the original data may specifically be processing the original data, and/or performing the original data. Calculate, and/or perform statistics on the raw data, and so on. In this way, the network element device shares a part of the data processing workload, which can reduce the workload of centralized processing of the network management device.
下面结合图 7所示的例子详细描述本发明实施例。 应注意， 这只是为了 帮助本领域技术人员更好地理解本发明实施例， 而非限制本发明实施例的范 围。  Embodiments of the present invention will be described in detail below with reference to the example shown in FIG. It should be noted that this is only to assist those skilled in the art to better understand the embodiments of the present invention and not to limit the scope of the embodiments of the present invention.
如图 7所示， 网元设备 710进行网络性能测量获取测量数据 720,例如， 按照 10秒测量周期产生的时延、 丟包、 抖动数据。 一方面， 将测量数据 720 存储为 MIB形式数据 721 , 通过 MIB接口提供给网管设备 730。 MIB形式 数据 721没有进行处理。 可选地， 可以设定 MIB形式数据 721保留的测量 数据 720的记录数目，如最多保留 M个记录 (M可以为大于 2的整数)。 另一 方面， 网元设备 710对测量数据 720按照统计周期进行处理， 将处理后的数 据存储为文本形式数据 722 , 以便于通过文本接口， 例如 FTP ( File Transfer Protocol, 文本传输协议）接口， 提供给网管设备 730。 例如， 按照统计周期 (如 15分钟）对测量数据 720进行处理， 如统计周期内的最大、 最小、 平 均值等， 这样网元设备 710可以分担一部分的数据处理工作量。  As shown in FIG. 7, the network element device 710 performs network performance measurement acquisition measurement data 720, for example, delay, packet loss, and jitter data generated according to a 10-second measurement period. On the one hand, the measurement data 720 is stored as MIB form data 721 and provided to the network management device 730 through the MIB interface. The MIB form data 721 is not processed. Alternatively, the number of records of the measurement data 720 retained by the MIB format data 721 may be set, such as up to M records (M may be an integer greater than 2). On the other hand, the network element device 710 processes the measurement data 720 according to a statistical period, and stores the processed data as text form data 722, so as to be provided through a text interface, such as an FTP (File Transfer Protocol) interface. The network management device 730 is provided. For example, the measurement data 720 is processed according to a statistical period (e.g., 15 minutes), such as the maximum, minimum, and average values in the statistical period, such that the network element device 710 can share a portion of the data processing workload.
网管设备 730在进行周期监控时， 按照监控周期（如 1小时）获取文本 形式数据 722,可以减少网管设备 730从网元设备 710获取测量数据的次数， 同时也减轻了网管设备 730的处理负荷。  The network management device 730 obtains the text form data 722 according to the monitoring period (for example, 1 hour) during the period monitoring, which can reduce the number of times the network management device 730 obtains the measurement data from the network element device 710, and also reduces the processing load of the network management device 730.
在需要进行实时监控时， 网管设备 730实时获取（例如， 以与测量周期 相同的 10秒的周期获取） MIB形式数据 721。 这样， 通过周期监控和实时 监控相互配合， 既可以获取持续的长期的结果， 又可以获取实时的短期的结 果。  When real-time monitoring is required, the network management device 730 acquires (for example, acquired in the same 10-cycle period as the measurement period) MIB-form data 721 in real time. In this way, through cycle monitoring and real-time monitoring, we can achieve continuous long-term results and real-time short-term results.
利用实时监控可以发起按需监控。 也就是说， 在周期监控时， 可以按照 需求， 发起同对象的实时监控， 按需测量。 这种发起是一键式的， 无需额外 配置， 无需创建任务。 在本发明实施例中， 可选地， 该网元设备为上游网元设备， 该上游网元 设备表示连接节点数量少于预定值的网元设备。 也就是说， 性能数据需要在 网络中节点较少的设备（上游设备）上采集。 On-demand monitoring can be initiated with real-time monitoring. That is to say, in the cycle monitoring, real-time monitoring of the same object can be initiated according to the demand, and measured as needed. This kind of initiation is one-click, no additional configuration is required, and no tasks need to be created. In the embodiment of the present invention, optionally, the network element device is an upstream network element device, and the upstream network element device indicates a network element device whose number of connected nodes is less than a predetermined value. That is, performance data needs to be collected on devices (upstream devices) with fewer nodes in the network.
例如， IP回传网络中， 从靠近基站控制器的路由器上采集数据； 光接入 网络中， 从 OLT或路由器上采集数据。  For example, in an IP backhaul network, data is collected from a router close to the base station controller; in an optical access network, data is collected from an OLT or a router.
因为网络末端设备众多， 在网络上游设备（如路由器 )上采集数据， 设 备交互次数少， 网络开销小， 网管设备解析文件次数少， 能够最优化发挥网 管设备的采集能力。  Because there are many devices at the end of the network, data is collected on the upstream devices of the network (such as routers). The number of device interactions is small, the network overhead is small, and the network management device resolves files less frequently, which optimizes the collection capability of the network management device.
在本发明实施例中， 可选地， S610 包括： 该网元设备利用双向时延报 文获取单向时延数据。  In the embodiment of the present invention, optionally, the S610 includes: the network element device uses the two-way delay message to obtain one-way delay data.
在现有技术中， 如监控 MxU (测量接收端， 即宿端） <->CX (测量发起 端， 即源端） 的管道性能质量的时延、 丟包、 抖动。 因 Y.1731 协议限制， 如果用户需要监控单向时延， 那么该信息需要在 MxU (测量接收端）上获 取。 也就是说， CX (测量发起端）发送单向时延报文 1DM, MxU (测量接 收端） 接收该单向时延报文 1DM , 根据等式， 单向时延 = RxTimef - TxTimeStampf, 计算单向时延。 其中， TxTimeStampf 表示该单向时延报文 1DM的发送时间戳， RxTimef表示该 1DM的接收时刻。 但是其他丟包、 抖 动等数据， 都需要在 CX (测量发起端）上获取。 这样导致网管设备需要在 MxU和 CX上同时获取性能数据， 采集工作量大。  In the prior art, for example, monitoring the performance quality delay, packet loss, and jitter of the pipeline performance quality of the MxU (measuring the receiving end, that is, the sinking terminal) <->CX (measurement originating end, that is, the source end). Due to the Y.1731 protocol limitation, if the user needs to monitor the one-way delay, then the information needs to be obtained on the MxU (measurement receiver). That is, the CX (measurement initiator) sends a one-way delay message 1DM, and the MxU (measurement receiver) receives the one-way delay message 1DM according to the equation, one-way delay = RxTimef - TxTimeStampf, calculation list To delay. The TxTimeStampf indicates the transmission timestamp of the 1DM delay message 1DM, and the RxTimef indicates the reception time of the 1DM. However, other data such as packet loss and jitter need to be obtained on the CX (measurement initiator). As a result, the network management device needs to acquire performance data on both the MxU and the CX, and the collection workload is large.
本发明实施例利用双向时延报文， 计算出单向时延的数据， 解决在测量 发起端获取不到单向时延的问题。  The embodiment of the present invention uses the two-way delay packet to calculate the data of the one-way delay, and solves the problem that the one-way delay is not obtained at the measurement initiator.
如果用户需要采集单向时延， 从 CX发起， 那么网管设备自动切换成双 向时延配置在网元设备上。 依据双向时延的报文能力， 将单向时延信息在 If the user needs to collect the one-way delay and initiate the attack from the CX, the network management device automatically switches to the two-way delay configuration on the NE device. According to the packet capability of two-way delay, the one-way delay information is
CX上计算出来。 Calculated on CX.
可选地， 该网元设备利用双向时延报文获取单向时延数据， 包括： 该网元设备根据以下至少一个等式获取单向时延数据，  Optionally, the network element device obtains one-way delay data by using the two-way delay packet, and the method includes: acquiring, by the network element device, one-way delay data according to at least one of the following equations,
正向单向时延 = RxTimeStampf - TxTimeStampf,  Forward one-way delay = RxTimeStampf - TxTimeStampf,
反向单向时延 = RxTimeb - TxTimeStampb,  Reverse one-way delay = RxTimeb - TxTimeStampb,
其中， TxTimeStampf 表示该双向时延报文中的时延测量报文 DMM的 发送时间戳， RxTimeStampf表示该 DMM的接收时间戳， TxTimeStampb表 示该双向时延报文中的时延测量应答 DMR的发送时间戳， RxTimeb表示该 DMR的接收时刻。 The TxTimeStampf indicates the transmission timestamp of the DMM of the delay measurement message in the two-way delay message, RxTimeStampf indicates the reception timestamp of the DMM, and TxTimeStampb indicates the transmission time of the delay measurement response DMR in the two-way delay message. Poke, RxTimeb indicates The receiving moment of the DMR.
具体而言， 在采用单向时延报文测量时， 目的网元进行计算。 单向时延 Specifically, when a one-way delay packet measurement is used, the destination network element performs calculation. One-way delay
= RxTimef - TxTimeStampf 。 = RxTimef - TxTimeStampf .
而采用双向时延 文测量时， 由于是双向的， 源网元进行计算。 双向时 延 = (RxTimeb - TxTimeStampf) - (TxTimeStampb - RxTimeStampf)。  When using two-way delay text measurement, since it is bidirectional, the source network element performs calculation. Bidirectional delay = (RxTimeb - TxTimeStampf) - (TxTimeStampb - RxTimeStampf).
正向单向时延 = RxTimeStampf - TxTimeStampf,  Forward one-way delay = RxTimeStampf - TxTimeStampf,
反向单向时延 = RxTimeb - TxTimeStampb。  Reverse one-way delay = RxTimeb - TxTimeStampb.
本发明实施例的网络性能测量的方法，通过在上游网元设备上采集网络 性能测量数据， 可以降低数据采集工作量， 减少网络开销， 能够最优化发挥 网管设备的采集能力， 从而能够提高网络性能测量的效率。  The network performance measurement method of the embodiment of the present invention can reduce the data collection workload, reduce the network overhead, and optimize the collection capability of the network management device, thereby improving network performance, by collecting network performance measurement data on the upstream network element device. The efficiency of the measurement.
图 8示出了根据本发明又一实施例的网络性能测量的方法 800的示意性 流程图。 如图 8所示， 该方法 800包括：  FIG. 8 shows a schematic flow diagram of a method 800 of network performance measurement in accordance with yet another embodiment of the present invention. As shown in Figure 8, the method 800 includes:
S810, 网管设备从网元设备实时获取该网元设备存储的网络性能测量的 原始数据， 基于该原始数据进行实时监控， 其中， 该原始数据由该网元设备 进行网络性能测量测得； 并且，  S810, the network management device obtains, in real time, the original data of the network performance measurement stored by the network element device from the network element device, and performs real-time monitoring based on the original data, where the original data is measured by the network element device for network performance measurement;
S820,该网管设备按照监控周期从该网元设备获取该网元设备存储的按 照统计周期处理后的数据， 基于该按照统计周期处理后的数据进行周期监 控， 其中， 该按照统计周期处理后的数据由该网元设备按照统计周期处理该 原始数据得到。  S820, the network management device obtains, according to the monitoring period, the data processed by the network element device according to the statistical period, and performs periodic monitoring based on the data processed according to the statistical period, where the network processing is performed according to the statistical period. The data is obtained by the network element device processing the original data according to a statistical period.
在本发明实施例中， 网元设备在进行网络性能测量， 获取网络性能测量 的原始数据时， 一方面， 存储该原始数据， 另一方面， 按照统计周期处理该 原始数据并存储按照统计周期处理后的数据； 网管设备可以从该网元设备实 时获取该原始数据以进行实时监控，按照监控周期从该网元设备获取该按照 统计周期处理后的数据以进行周期监控。 也就是说， 网元设备在进行网络性 能测量时， 存储两份数据， 一份是原始数据， 另一份是网元设备按照统计周 期处理后的数据。 网管设备在进行周期监控时， 按照监控周期从网元设备获 取按照统计周期处理后的数据， 在进行实时监控时， 从网元设备实时获取原 始数据。  In the embodiment of the present invention, when the network element device performs network performance measurement to obtain the original data of the network performance measurement, on the one hand, the original data is stored, and on the other hand, the original data is processed according to a statistical period and stored according to a statistical period. After the network management device obtains the original data from the network element device in real time for real-time monitoring, the data processed according to the statistical period is obtained from the network element device according to the monitoring period for periodic monitoring. That is to say, when the network element device performs network performance measurement, it stores two pieces of data, one is the original data, and the other is the data processed by the network element device according to the statistical period. When the network management device performs periodic monitoring, it obtains data processed by the network element device according to the statistical period according to the monitoring period. When real-time monitoring is performed, the original data is obtained from the network element device in real time.
由于网元设备先按照统计周期对原始数据进行了处理， 网管设备在进行 周期监控时， 获取的数据量降低， 因此数据传输和处理的压力降低。 这样， 可以通过周期监控进行持续不断的业务质量监控， 对网络进行主动监控， 分 析网络业务质量历史趋势， 回顾网络质量故障原因等。 The network element device first processes the original data according to the statistical period. When the network management device performs periodic monitoring, the amount of data acquired is reduced, so the pressure of data transmission and processing is reduced. In this way, continuous monitoring of service quality can be carried out through periodic monitoring, and the network can be actively monitored. Analyze the historical trend of network service quality, and review the causes of network quality failures.
因此， 本发明实施例的网络性能测量的方法， 通过网管设备获取原始数 据以进行实时监控， 获取按照统计周期处理后的数据以进行周期监控， 可以 降低传输数据量， 降低网管设备集中处理压力， 从而能够提高网络性能测量 的效率。  Therefore, the method for measuring the network performance of the embodiment of the present invention obtains the original data through the network management device for real-time monitoring, and obtains the data processed according to the statistical period for periodic monitoring, thereby reducing the amount of data transmitted and reducing the centralized processing pressure of the network management device. Thereby the efficiency of network performance measurement can be improved.
