为便于理解，在介绍本公开实施例之前，首先对本公开实施例中涉及到的几个名词进行解释如下：
Telemetry：即网络遥测，是一项远程地从物理设备或虚拟设备上高速采集数据的技术。网络设备通过推模式周期性的主动向采集器上送设备的接口流量统计、CPU或内存数据等信息，相对传统拉模式的一问一答式交互，提供了更实时更高速的数据采集功能。
OAM：英文全称为Operation Administration and Maintenance，译为“操作维护管理”。
下面结合附图及实施例对本示例实施方式进行详细说明。
首先，本公开实施例中提供了一种网络遥测方法，该方法可以由任意具备计算处理能力的电子设备执行，该电子设备可以是网络遥测系统中的源端设备、集中控制器或专门用于对OAM分类信息进行配置的分类器等设备。
图1示出本公开实施例中一种网络遥测方法流程图，如图1所示，本公开实施例中提供的网络遥测方法包括如下步骤：
S102，将OAM分类信息添加到OAM需求信息中，其中，OAM分类信息至少包含：待采集OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值。
需要说明的是，本公开实施例中，为了避免采集到大量重复且不必要的OAM信息，对待采集的OAM信息进行分类，并配置不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值，将这些OAM分类信息添加到下发给被测设备的OAM需求信息中，能够使得被测设备根据实时网络状态对各类OAM信息 进行选择性采集。
S104，将OAM需求信息发送给被测设备，其中，OAM需求信息用于被测设备对各类OAM信息进行选择性采集。
需要说明的是，本公开实施例中被测设备可以是网络上任一个被测的设备，在进行网络遥测时，为了避免采集到大量重复且不必要的OAM信息，对待采集的OAM信息进行分类，并将待采集的OAM分类信息添加到下发给被测设备的OAM需求信息中，能够使得被测设备根据实时网络状态对各类OAM信息选择性采集。
在具体实施时，上述S104可以通过如下两种方式将OAM需求信息发送给被测设备：
在本公开的一种实施方式中，可将OAM需求信息的具体数据内容(OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值等OAM分类信息)发送给被测设备，使得被测设备根据接收到的OAM需求信息中包含的OAM分类信息，对各类OAM信息进行选择性采集。
在本公开的另一种实施方式中，可预先OAM需求信息的具体数据内容(OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值等OAM分类信息)存储于被测设备，在采集OAM信息时，仅将待采集OAM信息的分类名称发送给被测设备，以便被测设备根据待采集OAM信息的分类名称，查询出相应的OAM分类信息，对各类OAM信息进行选择性采集。
在本公开的另一种实施方式中，可预先OAM需求信息的具体数据内容(OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值等OAM分类信息)存储于被测设备，在采集OAM信息时，仅将待采集OAM信息的分类名称、不同分类OAM信息之间的关联关系类型名称以及每类OAM信息对应的网络性能参数阈值等级名称发送给被测设备，以便被测设备根据待采集OAM信息的分类名称、不同分类OAM信息之间的关联关系类型名称以及每类OAM信息对应的网络性能参数阈值等级名称，查询出相应的OAM分类信息，对各类OAM信息进行选择性采集。
需要注意的是，本公开实施例中向被测设备下发OAM需求信息的方式包括但不限于上述三种实施方式，根据实际情况的不同，本领域技术人员还可采用其他的实施方式，例如，仅将部分OAM信息的分类下发给被测设备，将具有关联关系的一些分类预先存储于被测设备，当被测设备对某类OAM信息进行采集时，可触发采集一些未在OAM需求信息中指定的关联类的OAM信息。
由上可知，本公开的实施例中提供的网络遥测方法，将待采集OAM信息的分类、每类OAM信息对应的网络性能阈值以及不同分类OAM信息之间的关联关系添加到OAM需求信息中，下发给被测设备，使得被测设备能够根据采集各类OAM信息的网络性能参数阈值对各分类OAM信息进行选择性采集，实现动态调整网络遥测范围， 当采集某类OAM信息的网络性能参数大于该类OAM信息对应的网络性能参数阈值时，才会采集关联类的OAM信息；当采集某类OAM信息的网络性能参数小于该类OAM信息对应的网络性能参数阈值时，不再触发采集关联类的OAM信息，仅采集该类的OAM信息。
通过本公开实施例中提供的网络遥测方法，能够避免采集大量重复且不必要的OAM信息，极大节省链路资源，同时，也可以分流集中式控制器的工作量，极大节省集中控制器的计算资源。
在一些实施例中，上述S104中，可以将OAM需求信息添加到数据报文中，将携带OAM需求信息的数据报文发送给被测设备。
在具体实施时，可以将OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值等OAM分类信息全部写入到数据报文中，使得被测设备根据数据报文中携带的OAM分类信息直接对各类OAM信息进行采集；也可以将OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值等OAM分类信息预先存放于被测设备中，只需要将OAM分类名称写入数据报文即可让被测设备根据数据报文中携带OAM分类名称查询相应的分类信息，对各类OAM信息进行采集。后者，仅需要占用被测设备很少的存储空间来存储即可，从而减少OAM编程指令中携带的信息量。
在一些实施例中，上述S104中，可以将OAM需求信息添加到OAM编程指令中，将携带OAM需求信息的OAM编程指令发送给被测设备。在本公开的一个实施例中，OAM编程指令可以是添加到数据报文中的。
在具体实施时，可以将OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值等OAM分类信息全部写入到OAM编程指令中，使得被测设备根据OAM编程指令直接对各类OAM信息进行采集；也可以将OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值等OAM分类信息预先存放于被测设备中，只需要将OAM分类名称写入OAM编程指令即可让被测设备根据OAM编程指令中携带OAM分类名称查询相应的分类信息，对各类OAM信息进行采集。后者，仅需要占用被测设备很少的存储空间来存储即可，从而减少OAM编程指令中携带的信息量。
需要说明是的，上述数据报文是指网络上传输的用户数据报文，使用数据报文携带网络内各节点和路径的OAM信息，能够在不对网络造成影响的情况下，根据数据报文携带的OAM信息实时获取网络状态。根据网络状态不同，通常需要数据报文采集不同的OAM信息，上述OAM需求信息是指数据报文所需采集的OAM信息。
在一些实施例中，本公开实施例中提供的上述网络遥测方法还可包括如下步骤：按照预设分类方法对OAM信息进行分类；设置不同分类OAM信息之间的关联关系以及每类OAM信息的网络性能参数阈值。在按照预设分类方法对OAM信息进行分 类后，可指定其中一类或多类为初始类，也即OAM需求信息下发给被测设备后，由被测设备首先采集的OAM信息分类。在本公开的一个实施例中，可通过OAM编程指令或数据报文指定初始类。
需要说明的是，采用的分类方法不同，OAM信息的分类结果也不同，本公开实施例对具体采用的分类方法不作限定。在一些实施例中，可以按照开放式系统互连OSI参考模型将OAM信息划分为IP类OAM信息、传输类OAM信息和应用类OAM信息；在另外一些实施例中，还可以网络虚拟化模型，将OAM信息划分为虚拟化网络功能VNF类OAM信息和虚拟化网络功能实例VNFI类OAM信息。
进一步地，在一些实施例中，还可以结合多种分类方法对OAM信息进行分类，使得分类后的OAM信息之间的关联关系，不仅包括同一分类模型内纵向联动关系，还包括不同分类模型之间的横向联动关系。
图2示出本公开实施例中一种OAM信息分类示意图，如图2所示，处于同一模型内的OAM信息分类自上而下联动，处于不同模型内的OAM信息分类横向联动。
其次，本公开实施例中还提供了一种网络遥测方法，该方法也可以由任意具备计算处理能力的电子设备执行，该电子设备可以是网络遥测系统中的被测设备。
图3示出本公开实施例中又一种网络遥测方法流程图，如图3所示，该方法包括如下步骤：
S302，获取OAM需求信息，其中，OAM需求信息中至少包含：待采集OAM信息的分类、不同分类OAM信息之间的关联关系以及每类OAM信息对应的网络性能参数阈值。
需要说明的是，上述OAM需求信息可以由网络遥测系统中的源端设备或集中控制器或专门用于对OAM分类信息进行配置的分类器等设备下发的；在一些实施例中，可以是通过解析来自这些设备的数据报文获取到OAM需求信息的；在另一些实施例中，还可以是通过解析来自设备的OAM编程指令获取到OAM需求信息的。
S304，根据OAM需求信息，对各类OAM信息进行选择性采集。
在具体实施时，上述S304中，被测设备可根据实时网络状态，对OAM需求信息中的各类OAM信息进行选择性采集。
因而，在一些实施例中，上述S304可通过如下步骤来实现：根据OAM需求信息和采集各类OAM信息的网络性能参数，对各类OAM信息进行选择性采集。
在一些实施例中，根据OAM需求信息和采集各类OAM信息的网络性能参数，对各类OAM信息进行选择性采集包括：当采集第一OAM信息的网络性能参数小于或等于第一OAM信息对应的网络性能参数阈值，采集第一OAM信息；当采集第一OAM信息的网络性能参数大于第一OAM信息对应的网络性能参数阈值时，采集第一OAM信息和第二OAM信息，其中，第二OAM信息为OAM需求信中与第一OAM信息具有关联关系的OAM信息。
需要说明的是，上述第一OAM信息包括：当前采集的一类或多类OAM信息；上述第二OAM信息包括：与第一OAM信息具有关联关系的一类或多类OAM信息。在本公开的一个实施例中，第一OAM信息可以是从OAM需求信息中获取的，也可以是从上一次采集的第二OAM信息中获取的。在本公开的一个实施例中，可以根据OAM需求信息中指定的OAM分类顺序或优先级获取第一OAM信息，还可以根据预定的OAM分类顺序或优先级获取第一OAM信息。对于第一OAM信息(当前采集的类)和第二OAM信息(当前采集类的关联类)均包含一类OAM信息的情况，从数据报文或OAM编程指令或被测设备中预先存储的OAM分类信息中获取到待采集OAM信息的分类及关联关系为：采集A、B、C三类OAM信息，其中，B为A的关联类，C为B的关联类，当从数据报文或OAM编程指令中获取到第一OAM信息为A类时，若采集A类OAM信息的网络性能参数大于A类对应的网络性能参数阈值，则触发采集B类OAM信息；此时，B类作为当前采集的第一OAM信息，当采集B类OAM信息的网络性能参数大于该类对应的网络性能参数阈值时，触发采集C类OAM信息；此时，C类作为当前采集的第一OAM信息，由于已经没有其他待采集的OAM信息，则无论采集C类OAM信息的网络性能参数大于C类对应的网络性能参数阈值，还是小于C类对应的网络性能参数阈值，仅采集C类OAM信息即可。
对于第一OAM信息(当前采集的类)和第二OAM信息(当前采集类的关联类)均包含多类OAM信息的情况，从数据报文或OAM编程指令或被测设备中预先存储的OAM分类信息中获取到待采集OAM信息的分类及关联关系为：采集A、B、C、D、E、F、G、H八类OAM信息，其中，B、D、E为A的关联类，C为B的关联类，F为D的关联类，G为E的关联类，H为G的关联类，当从数据报文或OAM编程指令中获取到第一OAM信息为A类时，B类、D类、E类作为第二OAM信息，若采集A类OAM信息的网络性能参数大于A类对应的网络性能参数阈值，则触发采集B类、D类、E类的OAM信息；此时B类、D类、E类作为第一OAM信息，C类、F类、G类作为第二OAM信息，当采集B类OAM信息的网络性能参数大于B类对应的网络性能参数阈值时，触发采集C类OAM信息；当采集D类OAM信息的网络性能参数大于D类对应的网络性能参数阈值时，触发采集F类OAM信息；当采集E类OAM信息的网络性能参数大于E类对应的网络性能参数阈值时，触发采集G类OAM信息；此时，F类、G类作为第一OAM信息，H类作为第二OAM信息，由于F类没有关联类，则无论采集F类OAM信息的网络性能参数是否大于F类对应的网络性能参数阈值时，仅采集F类OAM信息；当采集G类OAM信息的网络性能参数大于G类对应的网络性能参数阈值时，触发采集H类OAM信息，此时H类作为第一OAM信息。
在另外一些实施例中，可能从数据报文或OAM编程指令获取到待采集OAM信息的分类为：采集A、B、C三类OAM信息，其中，B为A的关联类，C为B的关 联类，但从被测设备中预先存储的OAM分类信息中还获取到D、E为A的关联类，F为D的关联类，G为E的关联类，H为G的关联类，当从数据报文或OAM编程指令中获取到第一OAM信息为A类时，可触发采集B类、D类、E类的OAM信息，此时，B类、D类、E类作为第一OAM信息，当采集B类OAM信息的网络性能参数大于B类对应的网络性能参数阈值时，触发采集C类OAM信息；当采集D类OAM信息的网络性能参数大于D类对应的网络性能参数阈值时，触发采集F类OAM信息；当采集E类OAM信息的网络性能参数大于E类对应的网络性能参数阈值时，触发采集G类OAM信息；此时，C类、F类、G类作为第一OAM信息，H类作为第二OAM信息，其他情况类似，此处不再赘述。
可以看出，本公开实施例中关联触发的OAM信息分类可以是OAM需求信息内的分类，也可以是OAM需求信息以外的分类，通过这种方式，可根据网络状态，采集到更多关联类的OAM信息。
由上可知，本公开的实施例中提供的网络遥测方法，从OAM需求信息中获取待采集OAM信息的分类、每类OAM信息对应的网络性能阈值以及不同分类OAM信息之间的关联关系，能够根据实时网络状态对各分类OAM信息进行选择性采集，实现动态调整网络遥测范围，当采集某类OAM信息的网络性能参数大于该类OAM信息对应的网络性能参数阈值时，才会采集关联类的OAM信息；当采集某类OAM信息的网络性能参数小于该类OAM信息对应的网络性能参数阈值时，不再触发采集关联类的OAM信息，仅采集该类的OAM信息。
通过本公开实施例中提供的网络遥测方法，能够避免采集大量重复且不必要的OAM信息，极大节省链路资源，同时，也可以分流集中式控制器的工作量，极大节省集中控制器的计算资源。
在一些实施例中，在执行上述S304之后，本公开实施例中提供的网络遥测方法还包括如下步骤：当采集第一OAM信息的网络性能参数大于第一OAM信息对应的网络性能参数阈值时，将采集的第一OAM信息和第二OAM信息存储到网络遥测OAM信息存储模块，以便被测设备从网络遥测OAM信息存储模块中提取采集的第一OAM信息和第二OAM信息，将采集的第一OAM信息和第二OAM信息封装到数据报文中。
在一些实施例中，本公开实施例中提供的网络遥测方法还包括如下步骤：当采集第一OAM信息的网络性能参数小于或等于第一OAM信息对应的网络性能参数阈值时，将采集的第一OAM信息存储到网络遥测OAM信息存储模块，以便被测设备从网络遥测OAM信息存储模块中提取采集的第一OAM信息，并将采集的第一OAM信息封装到数据报文中。
本公开实施例中，利用网络遥测OAM信息存储模块存储采集的OAM信息，能够实现OAM信息采集与封装的异步处理。
图4示出相关技术中一种网络遥测方法的具体实现方案示意图，如图4所示，相关技术中提供的网络遥测方案，在读取用户数据报文中携带的OAM需求信息后，无论网络性能是好还是差，都将采集所有的OAM信息，而在网络状况较好时，报文会携带重复的且不必要的OAM信息，造成大量链路资源的浪费，鉴于Telemetry是亚秒级的OAM信息收集方式，对于集中式控制器来说要计算网络性能并给海量的报文下发不同需求的OAM指令的携带需求，是现阶段几乎不可能完成的任务。
图5示出本公开实施例中一种网络遥测方法的实现方案示意图，如图5所示，Telemetry OAM信息需求读取模块用于读取用户数据报文头中携带的Telemetry OAM信息(包括但不限于待采集OAM信息的分类信息)；Telemetry OAM信息采集模块用于对各类Telemetry OAM信息进行选择性采集；Telemetry OAM信息存储模块用于存储采集上来的Telemetry OAM信息。其中，Telemetry OAM信息采集模块包括OAM信息类模块(图4所示的第1～n类OAM信息模块)和OAM类关联关系模块。每类OAM信息模块包含了相应类的OAM信息，预先配置了该类OAM信息对应的网络性能参数阈值；OAM类关联关系模块用于存储各类之间的OAM信息触发关系。
假设待采集OAM信息包括第1～n类，预先配置最先采集的初始类为第1类，且后一类为前一类的关联类(例如，第2类是第1类的关联类，第3类为第2类的关联类，以此类推)，则根据本公开实施例中提供的网络遥测方法，可通过如下流程来对OAM信息进行采集：
当用户数据报文到达网络遥测系统，由Telemetry OAM信息需求读取模块获取该数据报文所需要采集的OAM类信息。首先读取初始类的OAM信息(即第1类OAM信息)，判断采集第1类OAM信息的网络性能参数是否大于该类对应的网络性能参数阈值(即阈值1)；若采集第1类OAM信息的网络性能参数大于阈值1，则触发采集第2类OAM信息；若采集第1类OAM信息的网络性能参数小于阈值1，则将第1类OAM信息发送给telemetry OAM信息存储模块，停止采集第2～n类的OAM信息。
当采集第2类OAM信息时，判断采集第2类OAM信息的网络性能参数是否大于该类对应的网络性能参数阈值(即阈值2)；若采集第2类OAM信息的网络性能参数大于阈值2，则触发采集第3类OAM信息；若采集第2类OAM信息的网络性能参数小于阈值2，则将第2类OAM信息发送给telemetry OAM信息存储模块，停止采集第3～n类的OAM信息；
当采集前面n-1类OAM信息的网络性能参数都大于对应类的网络性能参数阈值(即阈值n-1)时，触发采集第n类OAM信息；由于第n类已经为待采集OAM信息的最后一类，则不管采集该类OAM信息的网络性能参数是否大于该类的网络性能参数阈值，将只将其OAM信息上传给Telemetry OAM信息存储模块。最后，Telemetry OAM信息存储模块将存储的OAM信息重新封装在用户数据报文中。
需要说明的是，对于每类OAM信息，当网络性能参数等于相应类的网络性能参 数阈值，可选择按照小于阈值的方式进行，不采集关联类的OAM信息。
对比图4和图5可以看出，相关技术中提供的网络遥测方案，在网络性能良好时，收集所有OAM信息，绝大部分OAM信息无信息量；在网络性能较差时，收集所有OAM信息，可提供较大信息量；本公开实施例中提供的OAM信息采集方案，在网络性能良好时，只收集第1类OAM信息，无无效信息；在网络性能较差时，可依据网络性能状态，动态收集多类OAM信息，无无效信息。可见，本公开实施例中提供的网络遥测方法，可根据网络状态，在设备本地动态调整OAM信息的收集范围，杜绝收集无效重复的OAM信息。

由上可知，本公开的实施例中提供的上述网络遥测系统，由源端设备61将OAM分类信息添加到OAM需求信息中，并将OAM需求信息发送给被测设备62，使得被测设备62根据实时网络性能参数动态调整网络遥测范围，当采集某类待采集OAM信息的网络性能参数大于该类OAM信息对应的网络性能参数阈值时，才会采集关联类的OAM信息；当采集某类待采集OAM信息的网络性能参数小于该类OAM信息对应的网络性能参数阈值时，不再触发采集关联类的OAM信息，仅采集该类的OAM信息。
