技术领域
本公开实施例涉及通信领域，具体而言，涉及一种信息的收集方法、装置、存储介质及电子装置。
背景技术
在高速发展的信息时代，从个人到企业对信息的需求越来越多，依赖性也越来越大，因此通过网络技术收集大量信息时，对于信息传送与接收的通道是否正常且传送与接收的信息是否正确等问题备受社会关注，因此，段路由(Segment Routing，简称为SR)技术得到了快速发展，且嵌入到数据报文中的可编程网络功能也得到越来越广泛的应用。
相关技术中，与段路由技术一样，采用可编程网络功能转发平面主要有两种实现方式，第一种实现方式是在SRv6(Segment Routing over IPv6，IPv6段路由)数据报文中插入包含SRv6网络功能(SRv6Function)的段路由标识(Segment ID，简称为SID)，第二种实现方式是在MPLS(Multiprotocol Label Switching，多协议标签交换)数据报文中插入包含MPLS网络功能的MPLS标签(MPLS Label)，其中，无论采用哪种转发平面的实现方式，网络节点在接收到包含网络功能的数据报文后，都会解析并执行数据报文中包含的网络功能，但该技术中，对网络节点执行网络功能的行为没有实时的监控和分析，因此，不清楚网络节点所执行的网络功能信息是否正确且完整。
针对相关技术中存在的无法实时监控和分析网络节点执行网络功能行为的问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本公开的实施例。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
首先对本公开中涉及的相关技术进行说明：
国际标准组织互联网工程任务组(Internet Engineering Task Force，简称为IETF)发布的标准RFC 8986中定义了一系列SRv6网络功能，包括End.X(三层交叉连接)、End.T(查找特定IPv6表)、End.DX6(解封装及IPv6交叉连接)等等。图1是相关技术中包含SRv6网络功能的SRv6报文封装格式示意图，如图1所示，包含SRv6网络功能的SID被插入到SRv6数据报文中，用于该SID所属网络节点执行该SID包含的SRv6网络功能。
国际标准组织IETF的草案draft-kompella-mpls-mspl4fa-01中定义了一系列MPLS网络功能，包括多路径负荷分担(load balance)、流标识(Flow ID)处理、快速重路由(Fast Reroute)处理等等。图2是相关技术中包含MPLS网络功能的MPLS报文封装格式示意图，如图2所示，包含MPLS网络功能的MPLS标签被插入到MPLS数据报文中，用于MPLS网络节点执行该MPLS标签包含的MPLS网络功能。
无论采用哪种转发平面的实现方式，网络节点在接收到包含网络功能的数据报文后，都会解析并执行数据报文中包含的网络功能。随着大数据时代的发展，信息传输与接收的高效性、稳定性、可靠性备受人们的关注，为了避免信息接收不完整或接收到错误的信息，就需要对网络节点执行网络功能信息的行为进行监控和分析。然而，目前缺乏一种有效的方法，能够收集网络功能的执行信息，以实现对网络节点执行网络功能行为的监控和分析。针对如何实现实时监控和分析网络节点执行网络功能行为，在本公开实施例中提出了一种网络功能执行信息的收集方法，能够实现基于报文的带内操作管理维护IOAM头确定需要收集网络功能的执行信息(包括执行的网络功能的类型以及执行的结果等)，进而收集网络功能的执行信息。下面结合实施例对本公开进行说明：
本申请实施例中所提供的方法实施例可以在移动终端、计算机终端或者类似的运算装置中执行。以运行在移动终端上为例，图3是本公开实施例的一种信息的收集方法的移动终端的硬件结构框图。如图3所示，移动终端可以包括一个或多个(图3中仅示出一个)处理器302(处理器302可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)和设置为存储数据的存储器304，其中，上述移动终端还可以包括设置为通信功能的传输设备306以及输入输出设备308。本领域普通技术人员可以理解，图3所示的结构仅为示意，其并不对上述移动终端的结构造成限定。例如，移动终端还可包括比图3中所示更多或者更少的组件，或者具有与图3所示不同的配置。
存储器304可设置为存储计算机程序，例如，应用软件的软件程序以及模块，如本公开实施例中的信息的收集方法对应的计算机程序，处理器302通过运行存储在存储器304内的计算机程序，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器304可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器304可进一步包括相对于处理器302远程设置的存储器，这些远程存储器可以通过网络连接至移动终端。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置306设置为经由一个网络接收或者发送数据。上述的网络具体实例可包括移动终端的通信供应商提供的无线网络。在一个实例中，传输装置306包括一个网络适配器(Network Interface Controller，简称为NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置306可以为射频(Radio Frequency，简称为RF)模块，其设置为通过无线方式与互联网进行通讯。
在本实施例中提供了一种信息的收集方法，图4是根据本公开实施例的信息的收集方法的流程图，如图4所示，该流程包括如下步骤：
步骤S402，目标网络节点在接收到报文之后，确定所述报文的带内操作管理维护IOAM头；
步骤S404，所述目标网络节点在基于所述IOAM头确定出需要收集网络功能执行信息的 情况下，收集目标网络功能执行信息。
其中，上述步骤的执行主体可以是网络节点，或是网络设备等，例如，网络交换机、路由器等，此外，上述步骤的执行主体还可以是具备接收、收集、执行信息能力的单元或终端等。下面以网络节点执行上述操作为例(仅是一种示例性说明，在实际操作中还可以是其他的设备或模块来执行上述操作)进行说明。
在上述实施例中，目标网络节点可以是网络入口节点，可以是沿路网络节点还可以是网络出口节点，报文传输路径上的任一网络节点均可以执行上述的操作。其中，目标网络节点可以接收数据报文，进而基于数据报文的带内操作管理维护IOAM头确定收集网络功能执行信息，在实际应用中，收集网络功能执行信息的目标网络节点可以有多个，因此，数据报文的带内操作管理维护IOAM头可以指示收集多种网络功能执行信息。
在上述实施例中，网络节点在基于报文的带内操作管理维护IOAM头确定需要收集网络功能的执行信息的情况下，可以收集网络功能的执行信息，继而，可以根据收集到的网络功能及时的执行执行信息监控和分析网络节点，有效解决相关技术中不能实时监控和分析网络节点执行网络功能行为的问题。
在一个可选的实施例中，目标网络节点收集目标网络功能执行信息可以但不限于包括：所述目标网络节点基于接收到的报文中携带的功能指示信息确定出需要由所述目标网络节点所执行的目标网络功能；所述目标网络节点执行所述目标网络功能，并在基于所述IOAM头中携带的目标信息确定需要收集执行所述目标网络功能所产生的所述目标网络功能执行信息的情况下，基于执行结果收集所述目标网络功能执行信息。在本实施例中，所述目标网络节点基于接收到的数据报文中携带的功能指示信息，即，用于指示目标网络节点收集网络功能执行信息，确定出需要执行的目标网络功能，其中，在不同的协议报文中该指示信息可以是不同的，例如，对于IPv6段路由SRv6报文而言，该指示信息可以是基于报文的IPv6目的地址中所包括的信息确定的，即，目的地址中会包含需要当前接收到报文的网络节点所需要执行的功能；对于多协议标签交换MPLS报文而言，该指示信息可以是基于MPLS网络功能指示标签所包括的信息确定的，该MPLS网络功能指示标签中会包括用于指示需要执行哪个功能的指示信息，另外，该MPLS网络功能指示标签中可以不明确指定哪个节点执行哪个功能，网络节点在接收到报文后，会根据自身能力来确定自己所能执行的功能。
在一个可选的实施例中，目标网络节点基于执行结果收集所述目标网络功能执行信息可以但不限于包括：所述目标网络节点基于所述执行结果确定出所述目标网络节点所执行的所述目标网络功能的数量、执行的每一个所述目标网络功能的类型，以及执行的每一个所述目标网络功能的结果；所述目标网络节点将所述目标网络功能的数量、执行的每一个所述目标网络功能的类型，以及执行的每一个所述目标网络功能的结果确定为所述目标网络功能执行信息。在本实施例中，所述IOAM头可以携带多个指示信息用于指示不同网络节点收集网络功能执行信息，由于单个目标网络节点可以执行多个网络功能，因此，所述目标网络节点需要基于所述执行结果确定所述目标网络功能的数量、执行的每一个所述目标网络功能的类型，以及执行的每一个所述目标网络功能的结果，其中，执行每一个所述目标网络功能的结果包括执行成功或执行失败，如果执行的结果是失败，则也可以在收集的目标网络功能执行信息中加入执行失败的原因。
在一个可选的实施例中，所述目标网络节点在基于所述IOAM头中携带的目标信息确定 需要收集执行所述目标网络功能所产生的所述目标网络功能执行信息的情况下，基于执行结果收集所述目标网络功能执行信息包括：所述目标网络节点基于所述IOAM头中携带的比特地图确定出需要收集执行所述目标网络功能所产生的所述目标网络功能执行信息的情况下，基于执行结果收集所述目标网络功能执行信息；其中，所述比特地图中包括一串指示比特，所述一串指示比特中包括有目标指示比特，在所述目标指示比特取值为特定值的情况下，所述目标指示比特用于指示需要收集网络功能执行信息。在本实施例中，上述目标指示比特可以是所述比特地图中特定位置上的比特，具体将哪个位置上的比特作为目标指示比特可以是预先确定好的，此外，还可以在常规的比特地图中额外扩展一部分比特，从该扩展出的比特中确定上述目标指示比特。其中，在所述目标指示比特取值为特定值的情况下，即可确定出当前接收到报文的网络节点需要收集网络功能执行信息，例如，在目标指示比特取值为1的情况下，说明当前接收到报文的网络节点需要收集网络功能执行信息，或者在目标指示比特取值为0的情况下，说明当前接收到报文的网络节点需要收集网络功能执行信息，当然，也可以用其他的取值来指示当前接收到报文的网络节点收集网络功能执行信息。在上述比特地图中，不同位置上的比特位可以用于指示不同的操作，例如，收集其他类型的信息。通过上述比特地图可以确定是否需要由目标网络节点来收集目标网络功能执行信息，实际上本公开在现有技术基础上，只需要扩展比特地图中的1比特表示网络功能执行信息即可实现指示沿路上的各网络节点来收集网络功能执行信息。
在一个可选的实施例中，目标网络节点在收集目标网络功能执行信息之后还包括：所述目标网络节点按照所述IOAM头中携带的指示信息所指示的处理方式对所述目标网络功能执行信息进行处理。在本实施例中，所述目标网络节点可以基于所述IOAM头中携带的指示信息确定所述目标网络功能执行信息的处理方式，其中，该指示信息可以是IOAM头中包括的IOAM数据类型和处理方式字段中所包括的信息，另外，该处理方式可以有多种，例如，可以包括全部网络节点均将收集的网络功能执行信息添加到IOAM头，再由出口节点将IOAM头中包括的全部的网络功能执行信息导出给网络分析器进行分析的处理方式(可以称该方式为方式一)；还可以包括各网络节点均将收集的网络功能执行信息直接导出给网络分析器进行分析的处理方式(可以称该方式为方式二)；当然，还包括其他的处理方式，例如，部分网络节点将收集到的网络功能执行信息添加到IOAM头中，部分网络节点将收集的网络功能执行信息直接导出给网络分析器进行处理等等，在此不再赘述。
在一个可选的实施例中，目标网络节点按照所述IOAM头中携带的指示信息所指示的处理方式对所述目标网络功能执行信息进行处理包括：所述目标网络节点在确定所述指示信息用于指示按照第一处理方式(对应于上述的方式一)处理网络功能执行信息的情况下，将所述目标网络功能执行信息添加到所述IOAM头中；所述目标网络节点在确定所述指示信息用于指示按照第二处理方式(对应于上述的方式二)处理网络功能执行信息的情况下，将所述目标网络功能执行信息导出到网络分析器中，其中，所述网络分析器用于对所述目标网络功能执行信息进行分析。下面对两种处理方式进行具体描述：
在本实施例中，根据IETF(Internet Engineering Task Force，互联网工程任务组)草案draft-ietf-ippm-ioam-data-14和draft-ietf-ippm-ioam-direct-export-06的规定，目前有两种IOAM头的处理方式，其中，第一种处理方式包括：沿路每个网络节点(包括网络入口节点、网络中间节点和网络出口节点等)将收集到的由所述IOAM头所指示的目标网络功能执行信息添 加到所述IOAM头中，并由所述IOAM头携带每个网络节点交付的目标网络功能执行信息到网络出口节点，再由网络出口节点将IOAM头中携带的目标网络功能执行信息导出到网络分析器中进行分析处理；第二种处理方式包括：沿路每个网络节点(包括网络入口节点、网络中间节点和网络出口节点等)将收集到的由所述IOAM头所指示的目标网络功能执行信息先直接导出到网络分析器中进行分析处理，其中，每个网络节点无需将所述目标网络功能执行信息添加到IOAM头中。
在一个可选的实施例中，在所述目标网络节点为网络出口节点的情况下，所述方法还包括：所述目标网络节点在将所述目标网络功能执行信息添加到所述IOAM头中之后，将所述IOAM头中所添加的全部网络功能执行信息导出到所述网络分析器中，以及，剥离所述IOAM头，以恢复出原始数据报文。在本实施例中，在上述第一种处理方式中，所述目标网络节点将所述目标网络功能执行信息添加到所述IOAM头中之后，可以由所述网络出口节点将所述IOAM头中所添加的全部网络功能执行信息导出到所述网络分析器中，再由所述网络出口节点将IOAM头剥离，以恢复出原始数据报文，在实际应用中，所述网络分析器接收到所述网络节点收集的所述目标网络功能执行信息后，可以对所述目标网络节点实际执行的目标网络执行功能与期望执行的目标网络功能进行比较，若出现不匹配的异常情况，则可针对出现异常的目标网络节点做进一步的故障排查，进而针对出现的故障进行对应的处理。
在一个可选的实施例中，在所述目标网络节点为网络出口节点的情况下，所述方法还包括：所述目标网络节点在将所述目标网络功能执行信息导出到网络分析器中之后，剥离所述IOAM头，以恢复出原始数据报文。在本实施例中，在上述第二种处理方式中，所述目标网络节点可以将IOAM头中包括的全部的网络功能执行信息导出到网络分析器中，其中，在执行导出操作时，可以基于特定的导出顺序进行信息导出，例如，按预先配置的网络功能执行信息的导出优先级将所述目标网络功能执行信息依次导出，或者，按照收集网络功能执行信息的网络节点的优先级将各网络节点所收集到的所述目标网络功能执行信息依次导出，或者按照网络功能执行信息的收集时间(包括由先到后，还可以包括由后到先)将所述目标网络功能执行信息依次导出等等，在本实施例中，在导出目标网络功能执行信息之后，可以经由所述网络出口节点剥离所述IOAM头，以恢复出原始数据报文，在实际应用中，所述网络分析器接收到所述网络节点收集的所述目标网络功能执行信息后，可以对所述目标网络节点实际执行的目标网络执行功能与期望执行的目标网络功能进行比较，若出现不匹配的异常情况，则可针对出现异常的目标网络节点做进一步的故障排查，进而针对出现的故障进行对应的处理。
在一个可选的实施例中，上述方法还包括：网络入口节点执行在原始数据报文中添加所述IOAM头的处理，并沿目标传输路径发送处理后的报文，其中，所述目标传输路径上包括所述目标网络节点。在本实施例中，IOAM头可以是在路径的入口处由网络入口节点添加的。
在一个可选的实施例中，上述报文包括以下至少之一：IPv6段路由SRv6报文；多协议标签交换MPLS报文。在本实施例中，上述数据报文类型除了包括有IPv6段路由SRv6报文和多协议标签交换MPLS报文之外，还可以包括其他的具备类似结构或者类似处理方式的报文。
显然，上述所描述的实施例仅仅是本公开一部分的实施例，而不是全部的实施例。
下面结合具体实施例对本公开进行具体说明：
图5是根据本公开具体实施例的信息的收集方法的流程图，如图5所示，该流程包括如下步骤：
S502，网络入口节点给数据报文(IPv6段路由SRv6报文或多协议标签交换MPLS报文)添加带内操作管理维护(In-situ OAM，IOAM)头，用于指示沿路网络节点收集网络功能执行信息。
网络功能执行信息包括执行的网络功能的类型以及执行的结果，由于一个网络节点可能执行多于一个网络功能，因此，单个网络节点收集的网络功能执行信息包括网络节点所执行的目标网络功能的数量、执行的每一个目标网络功能的类型，以及执行的每一个网络功能的结果，其中，执行的每一个网络功能的结果包括执行成功或执行失败，若执行的结果是失败，则也可以包括执行失败的原因。在SRv6网络(针对IPv6段路由SRv6报文的应用)中，根据IETF的标准RFC 8986的定义，SRv6网络功能的类型包括，End.X(三层交叉连接)、End.T(查找特定IPv6表)、End.DX6(解封装及IPv6交叉连接)等，随着技术的发展，新的SRv6网络功能仍在被不断定义出来；MPLS网络(针对多协议标签交换MPLS报文的应用)中，根据IETF草案draft-kompella-mpls-mspl4fa-01的定义，MPLS网络功能的类型包括，多路径负荷分担(load balance)、流标识(FloW ID)处理、快速重路由(Fast Reroute)处理等，随着技术的发展，新的MPLS网络功能仍在被不断定义出来。
图6是根据本公开实施例的携带IOAM头的数据报文封装格式示意图，如图6所示，IOAM头是一种嵌入到数据报文中的用于网络节点信息收集的专用头部，根据IETF草案draft-ietf-ippm-ioam-data-14和draft-ietf-ippm-ioam-direct-export-06的规定，目前有两种IOAM头的处理方式，第一种处理方式是，沿路每个网络节点把IOAM头所指示的网络功能执行信息添加到IOAM头中，由IOAM头一路携带到网络的出口，再由网络出口节点把IOAM头剥离，并把其中携带的网络功能执行信息导出到网络分析器进行分析处理；第二种处理方式是，沿路每个网络节点把IOAM头所指示的网络功能执行信息直接导出到网络分析器进行分析处理，其中，网络节点基于IOAM头中携带的指示信息(对应于上述指示信息)确定出IOAM头的处理方式。
S504，沿路网络节点接收到数据报文后，根据IOAM头的指示信息收集网络功能执行信息，并根据IOAM头的指示对收集到的网络功能执行信息进行处理，其中，沿路网络节点收到数据报文后，会分析数据报文携带的IOAM头，根据IOAM头中的指示信息收集网络功能执行信息，并对收集到的网络功能执行信息进行处理，其中，所述沿路网络节点包括网络入口节点、网络中间节点和网络出口节点。
若IOAM头中的指示信息指示网络节点执行第一种处理方式，网络节点将收集到的网络功能执行信息添加到IOAM头中，再将数据报文往沿路的下一个网络节点转发，下一个接收到数据报文的网络节点也会将收集到的网络功能执行信息添加到IOAM头中，直到网络出口处，图7是根据本公开实施例的执行第一种处理方式的IOAM头封装格式示意图，如图7所示，IOAM数据类型和处理方式指示网络节点基于第一种处理方式确定收集逐跳跟踪类型的信息(一个网络节点一个网络节点的跟踪收集网络功能执行信息)，即沿路每个网络节点将收集到的网络功能执行信息添加到IOAM头中，其中，该IOAM比特地图(对应于上述比特地图)指示每个网络节点具体收集网络功能执行信息。
若IOAM头中的指示信息指示网络节点执行第二种处理方式，网络节点将收集到的网络功 能执行信息直接导出到网络分析器进行分析处理，与第一种处理方式的区别，网络节点收集到的网络功能执行信息不添加到IOAM头中，图8是根据本公开实施例的执行第二种处理方式的IOAM头封装格式示意图，如图8所示，IOAM数据类型和处理方式指示网络节点基于第二种处理方式确定收集逐跳跟踪类型的信息(一个网络节点一个网络节点的跟踪收集网络功能执行信息)，即沿路每个网络节点将收集到的网络功能执行信息直接导出到网络分析器中，而不添加到IOAM头中，其中，是IOAM比特地图(对应于上述IOAM比特地图)指示每个网络节点具体收集网络功能执行信息。
S506，网络出口节点基于IOAM头的指示信息确定收集网络出口节点的网络功能执行信息，并由网络出口节点剥离数据报文携带的IOAM头，恢复原始数据报文，若IOAM头中的指示信息指示网络节点执行第一种处理方式，网络出口节点先将本节点收集到的网络功能执行信息添加到IOAM头中，再将IOAM头中携带的沿路每一个网络节点添加的网络功能执行信息一起导出到网络分析器，并由网络出口节点剥离IOAM头，恢复原始数据报文。
若IOAM头中的指示信息指示网络节点执行第二种处理方式，网络出口节点将本节点收集到的网络功能执行信息直接导出到网络分析器，并剥离IOAM头，恢复原始数据报文，其中，不论执行的哪一种处理方式，网络分析器接收到网络节点收集的网络功能执行信息后，可以对网络节点实际执行的网络功能与期望执行的网络功能进行比较，一旦出现不匹配的异常情况，则可针对出现异常的网络节点做进一步的故障排查。
