Description

配置性能探测指示信息的方法及相关设备
本申请要求于2020年02月27日提交的申请号为202010125662.7、发明名称为“配置性能探测指示信息的方法及相关设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及路由技术领域，特别涉及一种配置性能探测指示信息的方法及相关设备。
背景技术
随着互联网技术的发展，对网络中各种数据流的性能探测越来越备受关注。对数据流的性能探测包括诸如路径拓扑、丢包率、传输时延等不同模式的性能探测。对数据流的性能探测需要通过采集数据流中的数据报文的转发节点的实时信息来实现。比如，当探测模式为路径拓扑探测模式时，则需收集各个转发节点收发数据报文的接口信息。而在对数据流进行性能探测之前，需在各个转发节点上配置性能探测指示信息，该性能探测指示信息用于指示对何种数据流进行何种探测模式的性能探测，以便后续各个节点基于该性能探测指示信息对接收到的数据报文进行探测数据的采集。
相关技术中，为了便于管理大型的网络，将网络划分为不同的自治系统(autonomous system，AS)。每个AS包括一组节点，这些节点可以为路由器等设备，同一AS内的各个节点由同一个控制器管理。当需要对在多个AS之间传输的数据流进行性能探测时，对于任一AS内的各个节点，技术人员通过控制器采用命令行或者NetConf(一种管理网络设备的机制)方式在各个节点配置性能探测指示信息。由于需要先通过人工方式在各个AS内的各个节点上配置性能探测指示信息，导致配置性能探测指示信息的效率较低。
发明内容
本申请提供了一种配置性能探测指示信息的方法及相关设备，可以提高配置性能探测指示信息的效率。所述技术方案如下：
第一方面，提供了一种配置性能探测指示信息的方法，该方法应用于通信网络中的控制节点，该通信网络还包括多个转发节点，这多个转发节点处于不同的AS内。在该方法中，控制节点确定性能探测指示信息，该性能探测指示信息用于指示待进行性能探测的数据流和对该数据流进行性能探测的一个或多个目标探测模式。基于边界网关协议(border gateway protocol，BGP)在该通信网络中发布第一通告报文，第一通告报文携带该性能探测指示信息，以使该多个转发节点在本端配置该性能探测指示信息。
在本申请实施例中，对BGP进行扩展，以使通信网络中的控制节点能够基于扩展后的BGP发布携带性能探测指示信息的第一通告报文。如此，当待进行性能探测的数据流是在多个不同的AS之间进行传输时，处于不同AS内的转发节点均可通过第一通告报文获取性能探测指示信息，以便于在本端配置该性能探测指示信息。也即是，通过第一通告报文可以实 现基于数据流的完整传输链对各个AS内的转发节点统一配置性能探测指示信息。这样就无需对于数据流的传输链中的每个AS单独通过AS内的控制节点基于人工方式来配置性能探测指示信息，从而提高配置性能探测指示信息的效率。并且由于可以实现基于数据流的完整传输链对各个AS内的转发节点统一配置性能探测指示信息，因此本申请相当于是从业务域的层次来直接配置性能探测指示信息，而不是从各个AS的管理域的层次来配置性能探测指示信息，如此在业务域大于管理域的情况下，通过本申请实施例提供的方法可以一次性配置全部管理域的性能探测指示信息，从而提高配置性能探测指示信息的效率。
基于第一方面提供的方法，在一种可能的实现方式中，第一通告报文可以为BGP FS路由报文，该BGP FS路由报文包括网络层可达性消息和执行动作指示消息。其中，该网络层可达性消息携带有第一指示信息，第一指示信息用于指示该数据流，该执行动作指示消息携带有第二指示信息，该第二指示信息用于指示这一个或多个目标探测模式。
在本申请实施例中，可以对BGP中已有的BGP FS路由报文进行扩展，以使BGP FS路由报文能够携带上述性能探测指示信息，无需扩展新的类型的报文，提高了配置性能探测指示信息的效率，同时也有利于推广本申请提供的配置性能探测指示信息方法。
基于第一方面提供的方法，在一种可能的实现方式中，上述执行动作指示消息还携带有第三指示信息，第三指示信息用于指示与一个或多个目标探测模式中每个目标探测模式关联的探测数据类型。其中，每个目标探测模式关联的探测数据类型用于指示在相应目标探测模式下需要收集的探测数据。
进一步地，为了便于各个转发节点在性能探测过程中采集信息，性能探测指示信息中还可以携带与目标探测模式关联的探测数据类型。如此，各个转发节点本端不仅配置有待进行的目标探测模式，还有与目标探测模式关联的探测数据类型，以便于后续转发节点在确定数据流与性能探测指示信息中指示的数据流匹配时，可以直接根据目标探测模式关联的探测数据类型收集探测数据，从而提高了后续收集探测数据的效率。
基于第一方面提供的方法，在一种可能的实现方式中，上述第二指示信息包括位图字段，该位图字段包括与多个探测模式一一对应的多个比特位，该多个比特位中与每个目标探测模式对应的比特位上的比特值为第一比特值，第一比特值用于指示使能相应的探测模式。
在本申请实施例中，可以通过上述位图字段中各个探测模式对应的比特位上的比特值来指示哪些探测模式为目标探测模式，提高了控制节点生成第一通告报文的效率，也提高了后续各个转发节点基于位图字段确定目标探测模式的效率。
基于第一方面提供的方法，在一种可能的实现方式中，可以在第一通告报文的第三指示信息设置参数字段，该参数字段用于指示每个目标探测模式关联的探测数据类型。也即是，通过在第一通告报文中设置参数字段来实现第一通告报文中携带目标探测模式关联的探测数据类型。
基于第一方面提供的方法，在一种可能的实现方式中，上述第一指示信息包括该数据流的源地址、源端口、目的地址、目的端口以及协议，该协议用于指示转发数据流中的数据报文所使用的协议。也即是，通过数据流的五元组特性来指示待探测的数据流为哪个数据流，提高了后续各个转发节点过滤待探测的数据流的效率。
基于第一方面提供的方法，在一种可能的实现方式中，在上述确定性能探测指示信息之前，在该方法中，还可以接收多个转发节点中的至少两个转发节点发送的第二通告报文。其 中，第二通告报文包括用于指示第二通告报文的发送方所支持的探测模式的指示信息。这种场景下，前述确定性能探测指示信息的实现方式可以为：获取需要对该数据流进行性能检测的一个或多个备选探测模式；根据第二通告报文从所述一个或多个备选探测模式中筛选出有效的探测模式作为这一个或多个目标探测模式；根据这一个或多个目标探测模式生成待配置的性能探测指示信息。
在本申请实施例中，支持各个转发节点的性能探测能力的发现，以便于控制节点能够筛选有效的探测模式，提高了后续各个转发节点收集探测数据的成功率。
第二方面、提供了一种配置性能探测指示信息的方法，应用于通信网络中的任一转发节点，该通信网络还包括多个转发节点和控制节点，这多个转发节点处于不同的AS内。在该方法中，转发节点接收控制节点基于BGP在该通信网络中发布的第一通告报文，该第一通告报文携带性能探测指示信息，该性能探测指示信息用于指示待进行性能探测的数据流和对该数据流进行性能探测的一个或多个目标探测模式。该转发节点在本端配置该性能探测指示信息。
在本申请实施例中，对BGP进行扩展，以使通信网络中的控制节点能够基于扩展后的BGP发布携带性能探测指示信息的第一通告报文。如此，当待进行性能探测的数据流是在多个不同的AS之间进行传输时，处于不同AS内的转发节点均可通过第一通告报文获取性能探测指示信息，以便于在本端配置该性能探测指示信息。也即是，通过第一通告报文可以实现基于数据流的完整传输链对各个AS内的转发节点统一配置性能探测指示信息。这样就无需对于数据流的传输链中的每个AS单独通过AS内的控制节点基于人工方式来配置性能探测指示信息，从而提高配置性能探测指示信息的效率。并且由于可以实现基于数据流的完整传输链对各个AS内的转发节点统一配置性能探测指示信息，因此本申请相当于是从业务域的层次来直接配置性能探测指示信息，而不是从各个AS的管理域的层次来配置性能探测指示信息，如此在业务域大于管理域的情况下，通过本申请实施例提供的方法可以一次性配置全部管理域的性能探测指示信息。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在对本申请实施例提供的配置性能探测指示信息的方法进行解释说明之前，先对本申请实施例涉及的应用场景进行解释说明。
目前，网络的智能运维也越来越备受关注。对网络的智能运维包括对网络中的各种数据 流的性能探测。在对数据流进行性能探测时，需要通过采集大量转发设备层的实时信息实现转发面可视，进行实现对数据流的性能探测。目前可以通过采集telemetry(远程测量)信息可以实现采集大量转发设备层的实时信息。其中，telemetry信息可以包括基于简单网络管理协议(simple network management protocol，SNMP)/NetConf等协议采集的设备存量信息和链路状态信息，还可以包括基于控制协议扩展的网络管理协议(network management protocol，NMP)采集的协议路由状态信息，还可以包括基于Netstream(网络流)协议采集流量特性，还可以包括基于随流操作、管理和维护(in-site operation administration and maintenance，iOAM)协议的五元组流的逐包的服务等级协议(service-level agreement，SLA)信息和路径信息。
随流流信息远程监测(in-site flow info telemetry，iFIT)或者iOAM技术是目前业界有关指定流的逐包带内性能监测技术。这两个技术中，在进行性能检测之前，均需先通过命令行或者Netconf方式来在各个AS内的各个节点上配置性能检测指示信息。例如，在头结点上配置数据流的五元组特征以及需要封装的监测数据的指令，在尾节点上配置数据流的五元组特征以及解封装指令。其中，数据流的五元组特征用于指示对何种数据流进行性能检测。
在各个节点上配置性能探测指示信息之后，头节点便可在数据报文中插入远程测量指导报文头(telemetry instruction header，TIH)以指导各跳中间节点基于该TIH采集探测数据(Metadata)，并上报采集的探测数据。
但在上述配置性能探测指示信息的过程中，都是通过命令行或者通过NetConf/YANG方式在各个转发设备上配置性能探测指示信息，也即是使能各个转发设备。如此，当数据流所在的域跨越多个AS时，便需针对各个AS配置性能探测指示信息，导致使能各个转发设备的效率极低。
目前在端到端(end to end，E2E)的性能探测中通常都是跨AS的性能检测。比如，企业专线场景中，数据流通过基于网络协议的无线接入网(internet protocol radio access network，IPRAN)接入、汇聚、跨越骨干后上云专线业务，通常可能要跨多个分层控制器，目前SDN底层控制器只负责每个AS内业务的自动发放和配置，所以针对E2E的性能探测，很容易出现控制器的控制域和数据流所在的域可能并非完全一致重合。这种情况下，通过命令行或者NetConf的方式配置性能探测指示的效率很低。因此，本申请实施例提供了一种配置性能探测指示信息的方法，通过控制协议的扩展来统一自动配置各个AS内的节点上的性能探测指示信息，以实现对数据流的性能检测自动化。
图1是本申请实施例提供的一种通信网络的架构示意图。如图1所示，该通信网络100包括控制节点101和多个转发节点102。任一转发节点102可与控制节点101通过有线或无线方式连接以进行通信。
各个转发节点102可以位于不同的AS内。图1是仅仅是以两个AS内的转发节点为例进行说明，并不构成对各个转发节点102所在的AS的限制。
控制节点101用于通过本申请实施例提供的方法向各个转发节点102下发性能探测指示信息，以实现无需通过命令行或者NetConf的方式即可配置性能探测指示信息。如此，当需要进行性能探测的数据流跨越多个AS时，只需控制节点一次性操作即可使能不同AS内的转发节点，从而提高使能各个转发节点的效率。
图1中的转发节点还可以称为网元、或者转发设备等，在此不做具体限定。
此外，图1中的控制节点可以为通信网络中的控制器、或者、网络性能集中分析器等设备，转发节点可以为路由器、或者、三层交换机等设备，同样在此不做具体限定。此外，需要说明的是，控制节点是可以实现基于BGP向多个不同的AS下发通告报文的控制节点，也即是，本申请实施例中的控制节点是AS层之上的控制节点，并不是某个AS内部的控制节点。
下面对本申请实施例提供的配置性能探测指示信息的方法进行详细解释说明。
图2是本申请实施例提供的一种配置性能探测指示信息的方法流程图。如图2所示，该方法包括如下几个步骤：
步骤201：控制节点确定性能探测指示信息，该性能探测指示信息用于指示待进行性能探测的数据流和对该数据流进行性能探测的一个或多个目标探测模式。
为了后续便于说明，将待进行性能探测的数据流称为目标数据流。在一种可能的实现方式中，当需要对目标数据流进行性能探测时，控制节点可以直接确定性能探测指示信息，以通过下述步骤202和步骤203在各个转发节点上配置性能探测指示信息。这种场景下，控制节点可以无需考虑各个转发节点的性能探测能力，只需通过下述步骤202和步骤203下发性能探测指示信息即可。
可选地，在向各个转发节点下发性能探测指示信息之后，如果各个转发节点自身不具备性能探测指示信息中指示的探测模式的能力，那么各个转发节点将无法成功对目标数据流进行性能探测。因此，在另一种可能的实现方式中，本申请实施例还支持各个转发节点性能探测能力的发现。
具体地，通信网络中的多个转发节点中的至少两个转发节点可以发送第二通告报文，第二通告报文包括用于指示第二通告报文的发送方所支持的探测模式的指示信息。如此，控制节点便可接收这至少两个转发节点发送的第二通告报文。在这种场景下，控制节点可以预先获知到各个转发节点所支持的探测模式。
此时，在步骤201中，控制节点确定性能探测指示信息的实现方式可以为：获取需要对目标数据流进行性能检测的一个或多个备选探测模式；根据第二通告报文从一个或多个备选探测模式中筛选出有效的探测模式作为一个或多个目标探测模式；根据这一个或多个目标探测模式生成性能探测指示信息。也即是，性能探测指示信息中指示的探测模式是控制节点确定的有效的探测模式。
上述根据第二通告报文从一个或多个备选探测模式中筛选出有效的探测模式的实现方式可以为：确定目标数据流的转发路径上的各个节点的上报的第二转发报文，对于任一备选探测模式，如果目标数据流的转发路径上的各个节点上报的第二通告报文中均支持该备选探测模式，则将该备选探测模式确定为有效的探测模式。或者，如果目标数据流的转发路径上的各个节点上报的第二通告报文中支持该备选探测模式的节点数量大于一定比例，则将该备选探测模式确定为有效的探测模式。本申请实施例中并不限定确定有效探测模式的具体实现方式，也即是，确定有效的探测模式和目标数据流的转发路径上的各个节点上报的第二通告报文中支持该备选探测模式的节点数量之间并没有强耦合关系。
此外，上述第二通告报文可以通过扩展IGP中的报文来实现，本申请实施例对此不作详细说明。比如，可以通过扩展IGP报文来实现转发节点随流信息远程监测(in-situ Flow Info  Telemetry，iFIT)能力的发现。
步骤202：控制节点基于BGP在通信网络中发布第一通告报文，第一通告报文携带该性能探测指示信息。
在本申请实施例中，为了能够实现统一对不同AS内的转发节点配置性能探测指示信息，可以对BGP协议进行扩展，得到第一通告报文，以通过第一通告报文来发布性能探测指示信息。
在一种可能的实现方式中，可以对目前BGP协议中的BGP流策略(flow specification，FS)FS路由报文进行扩展，以得到本申请实施例中的第一通告报文。也即是，第一通告报文可以为BGP FS路由报文。
为了后续便于说明，在此先对BGP FS路由报文进行简单介绍。BGP FS路由报文是BGP标准协议中定义的一种路由报文。BGP FS路由报文包含BGP网络层可达性消息(network layer reachability information，NLRI)和扩展团体属性。通过网络层可达性消息和扩展团体属性，BGP FS路由报文可以携带流量的过滤条件和流量过滤后执行的动作。也即是，通过BGP FS路由报文中的网络层可达性消息来指示流量的过滤条件，通过BGP FS路由报文中的扩展团体属性来指示流量过滤后执行的动作。
表1和表2分别是本申请实施例提供的一种BGP FS路由报文中的网络层可达性消息和扩展团体属性的示意表。表1中指示了流量的过滤条件。如表1所示，不同类型的网络层可达性消息可以指示不同的过滤条件，这些过滤条件可以包括目的地址为IPv4/IPv6类型的地址、源地址为IPv4/IPv6类型的地址等等。表2中指示了流量满足过滤条件后执行的动作。如表2所示，流量满足表1所示的过滤条件之后，可执行的动作包括不同类型的动作，如控制流量速度等动作。
表1
Figure PCTCN2020118670-appb-000001
表2
动作类型 动作
0X8006 控制流量速度
…… ……
因此，在本申请实施例中，可以利用BGP FS路由报文的原有功能来实现上述性能探测指示信息。此时，可以定义一种新的类型的网络层可达性消息来指示待性能检测的目标数据流，并定义一种新的类型的动作来指示对目标数据流进行性能检测的探测模式。
也即是，扩展后的BGP FS路由报文包括网络层可达性消息和执行动作指示消息。该网络层可达性消息携带有第一指示信息，第一指示信息用于指示目标数据流。该执行动作指示消息携带有第二指示信息，第二指示信息用于指示对目标数据流进行性能探测的一个或多个目标探测模式。通过第一指示信息和第二指示信息即可实现上述性能探测指示信息。
此外，为了便于指示对目标数据流进行性能探测的目标探测模式，上述第二指示信息可以包括位图字段，该位图字段包括与多个探测模式一一对应的多个比特位，这多个比特位中与每个目标探测模式对应的比特位上的比特值为第一比特值，第一比特值用于指示使能相应的探测模式。示例地，第一比特值可以为1。
比如，图3是本申请实施例提供的一种位图字段示意图。如图3所示，该位图字段包括n个比特位，每个比特位对应一个探测模式。比特位1对应探测模式1、比特位2对应探测模式2、比特位n对应探测模式n。这n个探测模式可以为随流信息探测逐跳追踪(Inband-Flow info telemetry postcard trace，iFIT PT trace)、随流操作管理维护追踪(insite-operation administration and maintenance trace，iOAM trace)、端对端(End 2 End，E2E)等探测模式。假设位图字段中的比特位1、比特位3以及比特位n上的比特值为1，其他比特位上的比特值为0，此时，则表明需要对目标数据流基于探测模式1、探测模式3以及探测模式n进行性能探测。
在配置了目标探测模式之后，如果各个转发节点预先能够通过其他途径(比如人工配置)获知每个探测模式下需要探测的数据的类型，此时，性能探测指示信息中则无需携带各个探测模式下需要探测的数据的类型。
可选地，如果各个转发节点预先无法获知每个探测模式下需要探测的数据的类型，此时，该执行动作指示消息还可以携带有第三指示信息，第三指示信息用于指示与一个或多个目标探测模式中每个目标探测模式关联的探测数据类型，每个目标探测模式关联的探测数据类型用于指示在相应目标探测模式下需要收集的探测数据。以便于后续各个转发节点在确定了目标探测模式后，基于目标探测模式关联的探测数据类型收集探测数据。
在一种可能的实现方式中，如图3所示，上述第三指示信息中包括参数字段，该参数字段用于指示每个目标探测模式关联的探测数据类型。也即是，在第三指示信息中设置参数字段，来指示每个目标探测模式关联的探测数据类型。
需要说明的是，上述第三指示信息中可以只携带各个目标探测模式关联的探测数据类型，如此，可以减少发布第一通告报文所占用的网络资源。可选地，为了避免在每次进行性能探测时都需要更新该第三指示信息，可以在第三指示信息中携带全部的探测模式关联的探测数 据类型，此时，通过第二指示信息可以确定哪些探测模式为目标探测模式，进而基于第三指示信息确定待收集的数据的类型。
此外，上述第一指示信息可以沿用目前BGP FS路由报文中过滤条件，此时第一指示信息可以包括目标数据流的五元组特性，也即是包括目标数据流的源地址、源端口、目的地址、目的端口以及协议。该协议用于指示转发目标数据流中的数据报文所使用的协议。当然，在本申请实施例中，第一指示信息还可以采用其他方式来指示目标数据流，在此就不再一一举例说明。
上述是以BGP FS路由报文为例来说明本申请实施例提供的第一通告报文。可选地，也可以采用BGP协议中的其他报文来实现第一通告报文，或者在用BGP协议中定义新的报文来实现第一通过报文，在此不做具体限定。
步骤203：通信网络中的第一转发节点接收第一通告报文，并在本端部署该性能探测指示信息。
控制节点在通过步骤202发布第一通告报文之后，通信网络中的各个转发节点便可基于步骤203在本端配置第一通告报文中携带的性能探测指示信息。上述第一转发节点可以是通信网络的任一转发节点，在此不再详细说明。
第一转发节点在本端配置了性能探测指示消息之后，后续对于任一数据流，便可基于性能探测指示信息对该数据流进行性能探测。后续对于任一数据流基于性能探测指示信息对数据流进行性能探测的具体实现方式可以参考相关技术，在此不再详细说明。比如，某个AS内的头节点在接收到该数据流的报文时，便可根据预先配置的探测指示信息在该报文中封装用于指示性能探测的报文头，以使该AS内的各跳中间节点根据该报文头进行信息收集。
在本申请实施例中，对BGP进行扩展，以使通信网络中的控制节点能够基于扩展后的BGP发布携带性能探测指示信息的第一通告报文。如此，当待进行性能探测的数据流是在多个不同的AS之间进行传输时，处于不同AS内的转发节点均可通过第一通告报文获取性能探测指示信息，以便于在本端配置该性能探测指示信息。也即是，通过第一通告报文可以实现基于数据流的完整传输链对各个AS内的转发节点统一配置性能探测指示信息。这样就无需对于数据流的传输链中的每个AS单独通过AS内的控制节点基于人工方式来配置性能探测指示信息，从而提高配置性能探测指示信息的效率。
