具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的时延的确定方法、装置、电子设备及存储介质进行详细地说明。
图1示出本申请实施例提供的一种时延的确定方法，该方法可以由电子设备执行，该电子设备可以包括：服务器和/或终端设备，其中终端设备可以是具有跨领域能力的设备等。换言之，该方法可以由安装在电子设备的软件或硬件来执行，该方法包括如下步骤。
步骤102：在目标传输过程中确定至少三个节点。
本申请实施例中，目标传输过程可以是垂直行业端到端的传输过程，例如网络包探索(Packet Internet Groper，ping)连接过程、传输控制协议(Transmission Control Protocol，TCP)二次握手、TCP三次握手、或TCP往返过程等。通常应用层的应用设备进行通信的过程中，会采集发送端应用设备与接收端应用设备之间的时延，例如在ping请求过程中，会采集发送ping连接请求的服务器设备和接收ping连接请求的挂接设备之间的时延，而不会考虑通信过程中所涉及的网络设备。在实际通信过程中，可能包含多个网络设备，例如核心网设备或接入网的网络设备等，相关技术中无法确定应用设备与网络设备之间、多个网络设备之间的时延。本发明实施例所述的至少三 个节点中至少包括一个网络设备节点。
步骤104：根据所述至少三个节点，将所述目标传输过程划分为至少两个子过程。
具体的，在目标传输过程中，可以根据确定的至少三个节点，将目标传输过程划分为至少两个子过程，由于通信过程通过会通过传输数据包实现信息的传输，因此子过程可以是一个节点发送数据包到另一个节点接收数据包之间的过程，或者是一个节点接收数据包到该节点发送数据包之间的过程，或者是一个节点接收数据包到另一个节点发送数据包之间的过程等。
作为一个示例，在目标传输过程中，存在O、M、N三个节点，其中，节点O表示发送端应用设备，节点N表示接收端应用设备，节点M表示网络设备节点，目标传输过程可以为节点O传输数据包至节点M、节点M再将数据包传输至节点N的过程，可以将节点O发送数据包到节点M接收数据包之间的过程确定为子过程m、将节点M发送数据包到节点N接收数据包之间的过程确定为子过程n,则节点O到节点M再到节点N的传输过程总共划分为m、n两个个子过程。
作为另外一个示例，在目标传输过程中，存在三个节点A、B、C，其中，节点A表示发送端应用设备，节点C表示接收端应用设备，节点B表示网络设备节点，目标传输过程可以为节点A传输数据包至节点B、节点B再将数据包传输至节点C的过程，可以将节点A发送数据包到节点B接收数据包之间的过程确定为子过程a，将节点B接收数据包到节点B发送数据包之间的过程确定为子过程b，将节点B发送数据包到节点C接收数据包之间的过程确定为子过程c，则节点A到节点B再到节点C的传输过程总共划分为a、b、c三个子过程，具体的目标传输过程划分方式可以根据需求进行设置，在此不做具体限定。
步骤106：在至少一个所述子过程中，确定数据包的发送时间信息和接收时间信息。
具体的，在将目标传输过程划分为至少两个子过程后，针对至少一个子过程，可以获取该子过程对应的数据包的发送时间信息和接收时间信息，发送时间信息可以包括发送数据包的时间戳，接收时间信息可以包括接收数据包的时间戳，接续步骤104中的示例，子过程m对应的数据包的发送时间信息即为节点O对应的数据包的发送时间信息，对应的数据包的接收时间信息即为节点M对应的数据包的接收时间信息，同理，子过程n对应的数据包的发送时间信息即为节点M对应的数据包的发送时间信息，对应的数据包的接收时间信息即为节点N对应的数据包的接收时间信息。
对于步骤104中的另外一个示例，子过程a对应的数据包的发送时间信息即为节点A对应的数据包的发送时间信息，对应的数据包的接收时间信息即为节点B对应的数据包的接收时间信息，同理，子过程b对应的数据包的发送时间信息即为节点B对应的数据包的发送时间信息，对应的数据包的接收时间信息即为节点B对应的数据包的接收时间信息，子过程c对应的数据包的发送时间信息即为节点B对应的数据包的发送时间信息，对应的数据包的接收时间信息即为节点C对应的数据包的接收时间信息。
步骤108：根据所述发送时间信息和所述接收时间信息，确定至少一个所述子过程的传输时延。
具体的，数据包的发送时间信息可以包括发送数据包的时间戳，接收时间信息可以包括接收数据包的时间戳，这样，在获取子过程的对应的数据包的发送时间信息和接收时间信息之后，可以根据发送时间信息和接收时间信息的差值，确定子过程对应的传输时延，接续步骤106中的示例，子过程m的传输时延即为节点O对应的数据包的发送时间信息与节点M对应的数据包的接收时间信息的差值，子过程n的传输时延即为子节点M对应的数据包的发送时间信息与节点N对应的数据包的接收时间信息的差值。
对于步骤106中的另外一个示例，子过程a的传输时延即为节点A对应的数据包的发送时间信息与节点B对应的数据包的接收时间信息的差值，子 过程b的传输时延即为子节点B对应的数据包的发送时间信息与节点B对应的数据包的接收时间信息的差值，子过程c的传输时延即为子节点B对应的数据包的发送时间信息与节点C对应的数据包的接收时间信息的差值。
在本申请实施例中，通过在目标传输过程中确定至少三个节点根据所述至少三个节点，将所述目标传输过程划分为至少两个子过程；在至少一个所述子过程中，确定数据包的发送时间信息和接收时间信息；根据所述发送时间信息和所述接收时间信息，确定至少一个所述子过程，根据子过程对应的发送时间信息和接收时间信息即可以确定端到端的目标传输过程中子过程对应的传输时延，实现了目标传输过程时延的分段，能够在目标传输过程出现问题的情况下，根据子过程的时延，可以准确地定位到问题所归属的子过程，进而实现能够对目标传输过程中出现的问题进行定位和分析，提高了目标传输过程中的问题的定位准确度和处理效率。
在本申请实施例中，通过在目标传输过程中确定至少三个节点；根据所述至少三个节点，将所述目标传输过程划分为至少两个子过程；在至少一个所述子过程中，确定数据包的发送时间信息和接收时间信息；根据所述发送时间信息和所述接收时间信息，确定至少一个所述子过程的传输时延，根据子过程对应的发送时间信息和接收时间信息即可以确定端到端的目标传输过程中子过程对应的传输，实现了目标传输过程时延的分段确定。
在一种实现方式中，所述至少三个节点包括第一节点和第二节点，根据所述发送时间信息和所述接收时间信息，确定至少一个所述子过程的传输时延，包括：确定所述第一节点发送所述数据包的第一发送时间信息；确定所述第二节点接收所述数据包的第二接收时间信息；根据所述第一发送时间信息和所述第二接收时间信息，确定从所述第一节点发送所述数据包到所述第二节点接收所述数据包之间的第一子过程的第一时延。
具体的，目标传输过程的至少三个节点中包括第一节点和第二节点，则可以将第一节点发送数据包到第二节点接收数据包之间过程确定为第一子过 程，因此，在目标传输过程中，可以获取第一子过程对应的发送数据包的第一发送时间信息，即第一节点发送数据包的第一发送时间信息，获取第一子过程对应的接收数据包的第二接收时间信息，即第二节点接收数据包的第二接收时间信息，那么第一子过程的传输时延即为第一发送时间信息和第二接收时间信息的差值，例如步骤106中的示例，其中，第一子过程可以为子过程m，第一节点可以为节点O，第二节点可以为节点M，那么节点O对应的数据包的发送时间信息即为第一发送时间信息，节点M对应的数据包的接收时间信息即为第二接收时间信息，则第一子过程m的时延即为第一发送时间信息和第二接收时间信息的差值。
这样，通过确定第一节点发送数据包的第一发送时间信息；确定第二节点接收数据包的第二接收时间信息；根据第一发送时间信息和第二接收时间信息，确定从第一节点发送数据包到第二节点接收数据包之间的第一子过程的第一时延，能够确定第一节点发送数据包到第二节点接收数据包之间的传输时延，进而能够在目标传输过程中出现问题的情况下，根据第一子过程的传输时延，能够快速准确地确定问题归属的子过程，提高问题的定位准确度和处理效率。
在一种实现方式中，所述至少三个传输节点包括第三节点，根据所述发送时间信息和所述接收时间信息，确定至少一个所述子过程的传输时延，包括：确定所述第三节点接收所述数据包的第三接收时间信息；确定所述第三节点发送所述数据包的第三发送时间信息；根据所述第三发送时间信息和所述第三接收时间信息，确定所述第三节点内部的第二子过程发送所述数据包的第二时延。
具体的，在目标传输过程中，包括第三节点，则可以将第三节点接收数据包到第三节点发送数据包之间的过程确定为第二子过程，该第二子过程即为第三节点内部传输数据包的过程，因此，在目标传输过程中可以获取第三节点接收数据包的第三接收时间信息和第三节点发送数据包的第三发送时间 信息，那么，第二子过程对应的传输时延即为第三发送时间信息与第三接收时间信息的差值，例如步骤106中的示例，其中，第二子过程可以是子过程b，第三节点可以是节点B，第三发送时间信息即为节点B对应的发送数据包时间信息，第三接收时间信息即为节点B对应的接收数据包时间信息，则第二子过程b的传输时延即为第三接收时间信息与第三发送时间信息的差值。
这样，通过确定第三节点接收数据包的第三接收时间信息；确定第三节点发送数据包的第三发送时间信息；根据第三发送时间信息和第三接收时间信息，确定第三节点内部的第二子过程发送数据包的第二时延，能够确定节点内部子过程的传输时延，根据节点内部子过程的传输时延，能够快速准确地确定问题归属的子过程，提高问题的定位准确度和处理效率。
在一种实现方式中，所述至少三个传输节点包括第四节点和第五节点，根据所述发送时间信息和所述接收时间信息，确定至少一个所述子过程的传输时延，包括：根据所述第四节点对应的第四时间信息和所述第五节点对应的第五时间信息，确定所述第四节点和所述第五节点之间的第三子过程对应的第三时延；其中，所述第四时间信息包括以下至少一种：从发送所述数据包到接收到所述数据包对应的反馈数据包之间的时间信息；从发送所述数据包到发送所述反馈数据包之间的时间信息；从接收所述数据包到接收到所述反馈数据包之间的时间信息；从接收所述数据包到发送所述反馈数据包之间的时间信息；所述第五时间信息包括以下至少一种：从接收所述数据包到接收到所述反馈数据包之间的时间信息；从发送所述数据包到接收到所述反馈数据包之间的时间信息；从接收所述数据包到发送所述反馈数据包之间的时间信息；从发送所述数据包到发送所述反馈数据包之间的时间信息。
具体的，发送端应用设备将数据包发送至接收端应用设备之后，接收端应用设备可能会返回反馈数据包，该反馈数据包由接收端应用设备响应于接收到的数据包产生，接收端应用设备发送的反馈数据包会延数据包的发送链路原路返回至发送端应用设备，因此，在至少三个节点包括第四节点和第五 节点的情况下，可以将第四节点和第五节点之间的传输过程确定为第三子过程，该第三子过程可以包括第四节点和第五节点之间传输数据包的过程和传输反馈数据包的过程，根据第四节点对应的第四时间信息和第五节点对应的第五时间信息可以确定第三子过程的传输时延。
第四节点可以发送数据包、接收数据包、发送反馈数据包或者接收反馈数据包，第五节点也可以发送数据包、接收数据包、发送反馈数据包或者接收反馈数据包，因此，第四时间信息可以包括从第四节点发送数据包到接收到反馈数据包之间的时间信息、从发送数据包到发送反馈数据包之间的时间信息、从接收数据包到接收到反馈数据包之间的时间信息、从接收数据包到发送反馈数据包之间的时间信息中的至少一者，第五时间信息可以包括第五节点从接收数据包到接收到反馈数据包之间的时间信息、从发送数据包到接收到反馈数据包之间的时间信息、从接收数据包到发送反馈数据包之间的时间信息、从发送数据包到发送反馈数据包之间的时间信息中的至少一者，这样，可以根据时间需求确定第三子过程的范围，并确定第四时间信息和第五时间信息，进而根据第四时间信息和第五时间信息的差值，可以直接确定第三子过程的时延，其中，第三子过程包括数据包传输子过程和反馈数据包传输子过程。
作为一个示例，第三子过程包括第五节点发送数据包到第四节点接收数据包的子过程和第四数据包发送反馈数据包到第五节点接收反馈数据包的子过程，则第四时间信息可以包括第四节点从接收数据包到发送反馈数据包之间的时间信息，该第四时间信息可以包括第四节点发送反馈数据包的时间戳与接收数据包的时间戳的差值，第五时间信息可以包括第五节点从发送数据包到接收反馈数据包之间的时间信息，该第五时间信息可以包括第五节点接收到反馈数据包的时间戳与发送数据包的时间戳的差值，则可以根据第五时间信息和第四时间信息的差值，确定第三子过程的传输时延。
这样，通过根据第四节点对应的第四时间信息和第五节点对应的第五时 间信息，确定第四节点和第五节点之间的第三子过程对应的第三时延；其中，第四时间信息包括以下至少一种：从发送数据包到接收到数据包对应的反馈数据包之间的时间信息；从发送数据包到发送反馈数据包之间的时间信息；从接收数据包到接收到反馈数据包之间的时间信息；从接收数据包到发送反馈数据包之间的时间信息；第五时间信息包括以下至少一种：从接收数据包到接收到反馈数据包之间的时间信息；从发送数据包到接收到反馈数据包之间的时间信息；从接收数据包到发送反馈数据包之间的时间信息；从发送数据包到发送反馈数据包之间的时间信息，可以根据需求确定第三子过程的范围，确定第四时间信息和第五时间信息，进而根据第四时间信息和第五时间信息的差值，可以直接确定包括数据包传输过程和反馈数据包传输过程的第三子过程的时延，避免了传输流传过程过长导致时延计算冗杂，提升了时延的确定效率。
在一种实现方式中，所述节点的数量小于或等于所述目标传输过程中包括的总节点数量。
具体的，在目标传输过程中确定节点进行子过程划分时，节点的数量可以小于或者等于目标传输过程中包括的总节点的数量，即，可以按照时间需求确定需要进行划分子过程的节点，避免了对所有节点进行划分导致资源浪费、时延确定过程冗杂的问题。
在一种实现方式中，所述目标传输过程包括网络包探索ping过程，所述数据包包括ping请求数据包。
具体的，目标传输过程可以包括网络包探索ping过程，则数据包包括ping请求数据包，在接收端应用设备接收到ping请求数据包的情况下，接收端应用设备还可以发送反馈数据包至发送端应用设备，应理解，本申请实施例中的目标传输过程除了可以包括ping过程以外，还可以包括TCP二次握手、TCP三次握手、TCP往返过程等端到端通信过程。
这样，通过对网络包探索ping过程等端到端通信过程进行子过程的划分， 然后确定子过程的传输时延，实现了目标传输过程时延的分段，能够在目标传输过程出现问题的情况下，根据子过程的传输时延，可以准确地定位到问题所归属的子过程，进而实现能够对目标传输过程中出现的问题进行定位和分析，提高了目标传输过程中的问题的定位准确度和效率。
图2示出的是本申请实施例提供的一种网络包探索ping过程的示意图，下面将图2作为一个示例，对本申请实施例提供的一种时延的确定方法进行详细的说明。
如图2所示，在服务器ping挂接设备的过程涉及服务器201、用户平面功能网元(User Plane Function，UPF)节点202、5G基站(gNB)节点203、终端设备204、挂接设备205，挂接设备205是终端设备204的下挂设备，服务器201可以将ping请求数据包通过UPF节点202、gNB节点203发送至终端设备204，通过终端设备204再转发至挂接设备205，挂接设备205可以通过终端设备204、gNB节点203、UPF节点202将反馈数据包发送至服务器201。
如图2所示，可以将节点之间的传输过程确定为子过程，还可以将节点内部的传输过程确定为子过程，例如在服务器201将ping请求数据包传输至挂接设备205的过程或者挂接设备205将反馈数据包输送至服务器201的过程中，可以将服务器201与UPF节点202之间传输过程、UPF节点202与gNB节点203之间的传输过程、gNB节点203与终端设备204之间的传输过程、终端设备204与挂接设备205之间的传输过程各确定为子传输过程，还可以将UPF节点202内部的传输过程、gNB节点203内部的传输过程等内部传输过程确定为子传输过程，当然，对于同一个节点，从发送ping请求数据包到接收到反馈数据包之间的过程也可以确定为子过程，子过程可以根据实际需求进行设定，在此，不对子过程做具体限定，在确定子过程之后可以根据各个子过程对应的发送数据包的时间和对应的数据包的接收时间信息，确定各个子过程的传输时延。
作为一个示例，在服务器201ping挂接设备205的过程中，可以获取服务器201发送ping请求数据包的时间信息TA1、服务器201接收反馈数据包的时间信息TA2，还可以获取UPF节点202通过N3口发送ping请求数据包的时间信息TB1、UPF节点202接收反馈数据包的时间信息TB2，还可以通过gNB节点203的分组数据汇聚层(Packet Data Convergence Protocol，PDCP)获取gNB节点203接收ping请求数据包的时间信息TC1、发送反馈数据包的时间信息TC4，还可以通过gNB节点203的PDCP层识别ping请求数据包或者反馈数据包，之后将ping请求数据包或者反馈数据包附带识别标签给将媒体接入控制层(media access control，MAC)或者无线链路控制协议层(Radio link Control，RLC)，然后由MAC或RLC提取出ping请求数据包或者反馈数据包的帧号或时隙(slot)号，即空口时刻，以获取gNB节点203发送ping请求数据包的时间信息TC2或者gNB节点203接收反馈数据包的时间信息TC3，其中，由预设触发器触发获取ping请求数据包或者反馈数据包的帧号或时隙(slot)号，获取周期也在触发器中预先设定，还可以获取终端设备204接收ping请求数据包的时间信息TD1、发送反馈数据包的时间信息TD2，还可以获取挂接设备205接收ping请求数据包的时间信息TE1、发送反馈数据包的时间信息TE2。
在预先根据传输过程中的节点确定的各个子过程中，可以根据TA1与TA2的差值，确定整个服务器201ping终端设备204过程的时延，根据TB1和TB2之间的差值，确定从UPF节点202发送ping请求数据包到接收到反馈数据包的时延，根据TC1与TC4之间的差值，确定从gNB节点203接收到ping请求数据包到发送反馈数据包的时延，根据TC2与TC3之间的差值，确定从gNB节点203发送ping请求数据包到gNB节点203接收到反馈数据包的时延，还可以通过TD1与TD2之间的差值，确定从终端设备204接收到ping请求数据包到发送反馈数据包之间的时延，还可以通过TE1和TE2之间的差值，确定挂接设备205内部的时延。
还可以根据服务器201ping终端设备204过程的时延与从UPF节点202发送ping请求数据包到接收到反馈数据包的时延的差值，确定服务器201与UPF节点202之间的时延；还可以根据从UPF节点202发送ping请求数据包到接收到反馈数据包的时延与从gNB节点203接收到ping请求数据包到发送反馈数据包的时延的差值，确定UPF节点202与gNB节点203之间的时延，还可以根据从gNB节点203接收到ping请求数据包到发送反馈数据包的时延与gNB节点203发送ping请求数据包到接收反馈数据包的时延的差值。
同样的，挂接设备205ping服务器201的过程，时延分段确定的方式与上述服务器201ping挂接设备205的过程中时延分段确定方式的原理相似，在挂接设备205ping服务器201的过程中，可以获取各节点发送ping请求数据包/反馈数据包以及接收ping请求数据包/反馈数据包的时间信息，根据时间信息，确定挂接设备205ping服务器201过程中各个预先确定的子过程的传输时延，上述示例仅仅是示意性的，而不是限制性的，本申请可以根据实际需求进行调整，并不局限于上述的具体实施方式。
这样，通过对网络包探索ping过程等端到端通信过程进行子过程的划分，然后确定子过程的传输时延，实现了目标传输过程时延的分段，能够在目标传输过程出现问题的情况下，根据子过程的传输时延，可以准确地定位到问题所归属的子过程，进而实现对目标传输过程中出现的问题进行定位和分析，提高了目标传输过程中的问题的定位准确度和处理效率。
