Description

一种报文处理方法及装置
本申请要求于2020年12月29日提交中国专利局、申请号为202011602762.0、申请名称为“一种报文处理方法及装置”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
本申请涉及网络技术领域，尤其涉及一种报文处理方法及装置。
背景技术
深度报文解析(deep packet inspection，DPI)系统通常部署在网元侧，来收集网络协议(internet protocol，IP)报文并生成终端上网记录详单(x detail record，xDR)单据，该xDR单据可以用于度量网络质量，帮助客户优化网络。对于用户面DPI，长期演进(long term evolution，LTE)网络通常部署在服务网关(serving gateway，SGW)侧采集IP报文，第五代移动通信技术(5-Generation，5G)通常在用户面功能(user plane function，UPF)侧采集IP报文。对于大型的DPI系统，由于采集IP报文的数量较大，可能由很多服务器构成的一个服务器集群采集IP报文。
DPI系统通过物理链路分光后接入汇聚交换机，汇聚交换机将收集的IP报文进行汇聚分流。当DPI系统包括多台服务器时，需要将接收到的IP报文分流到不同的DPI服务器。但是，由于同一终端设备在不同的网元之间移动或者使用IPv4/IPv6双栈等原因，可能导致一个终端设备的同一业务的IP报文被分发到不同的DPI服务器，影响基于IP报文生成的xDR单据的准确性。
发明内容
本申请实施例提供一种报文处理方法及装置。使得同一个终端设备的报文分发给同一个服务器处理，不仅减少了报文转发的数量，节省网络流量，而且提高了生成xDR单据的准确性。
第一方面，本申请实施例提供了一种报文处理方法，可以应用于第一服务器，或者第一服务器中的部件，例如，芯片、处理器等，该方法包括：接收来自终端设备的第一报文，基于第一报文确定终端设备的IP地址；基于终端设备的IP地址和第一锚点信息，确定是否由第一服务器处理第一报文，第一锚点信息包括终端设备的IP地址与第二服务器的IP地址的对应关系；当第一服务器的IP地址与第二服务器的IP地址不相同时，第一服务器根据第二服务器的IP地址向第二服务器转发第一报文。在第一服务器为非锚点服务器的情况下，第一服务器通过第一锚点信息将终端设备的第一报文转发给锚点服务器处理，使得同一个终端设备的报文分发给同一个服务器处理，不仅减少了报文转发的数量，节省网络流量，而且提高了生成xDR单据的准确性。
在一种可能的设计中，当第一服务器的IP地址与第二服务器的IP地址相同时，第一服务器对第一报文进行处理。保障终端设备的报文是同一个服务器处理，从而提高了生成xDR单据的准确性。
在另一种可能的设计中，第一服务器从预设的IP地址与MAC地址的对应关系中查找与第二服务器的IP地址对应的第二服务器的MAC地址；根据第二服务器的MAC地址，向第二服务器发送第一报文。通过第二服务器的MAC地址，实现将第一报文转发给第二服务器处理，使得终端设备的报文分发给同一个服务器处理，从而提高了生成xDR单据的准确性。
在一种可能的设计中，该方法还可以应用于第二服务器，或者第二服务器中的部件，例如，芯片、处理器等，该方法包括：接收来自终端设备的第二报文，基于第二报文确定终端设备的IP地址；向控制服务器发送终端设备的IP地址和第二服务器的IP地址，其中，终端设备的IP地址和第二服务器的IP地址用于生成第一锚点信息。在第二服务器为锚点服务器的情况下，控制服务器通过收集第二服务器的IP地址和终端设备的IP地址生成第一锚点信息，以便通过第一锚点信息使得同一个终端设备的报文分发给同一个服务器处理，不仅减少了报文转发的数量，节省网络流量，而且提高了生成xDR单据的准确性。
在另一种可能的设计中，第二服务器与第一服务器可以是同一个服务器，也可以是不同的服务器。
在另一种可能的设计中，第一锚点信息包括第二锚点信息，第二服务器确定从第二锚点信息中是否查找到终端设备的IP地址；当从第二锚点信息中未查找到终端设备的IP地址时，向控制服务器发送终端设备的IP地址和第二服务器的IP地址。通过确定从第二锚点信息中是否查找到终端设备的IP地址，保障终端设备对应的锚点服务器的唯一性，从而提高报文转发的准确性。
在另一种可能的设计中，终端设备的IP地址为第一IP地址或第二IP地址，第二服务器向控制服务器发送控制面信息，控制面信息包括终端设备的第一IP地址和第二IP地址，第一锚点信息包括第一IP地址、第二IP地址与第二服务器的IP地址的对应关系。在双栈情况下，通过建立终端设备的双IP地址与第二服务器的对应关系，这样终端设备无论使用哪一个IP地址来发送报文，均可以从第一锚点信息中查找到终端设备的IP地址，保障报文转发的准确性。
在另一种可能的设计中，第二服务器接收来自控制服务器的第一锚点信息。第二服务器通过接收第一锚点信息，可以根据第一锚点信息处理终端设备发送的所有报文，使得终端设备的报文分发给同一个服务器处理，从而提高了生成xDR单据的准确性。
第二方面，本申请实施例提供了一种报文处理方法，可以应用于控制服务器，或者控制服务器中的部件，例如，芯片、处理器等，该方法包括：生成第一锚点信息，第一锚点信息包括终端设备的IP地址与第二服务器的IP地址的对应关系，第二服务器用于处理终端设备的报文；然后广播第一锚点信息。控制服务器通过广播第一锚点信息，使得服务器集群中所有服务器可以根据第一锚点信息将终端设备的报文分发给同一个服务器处理，不仅减少了报文转发的数量，节省网络流量，而且提高了生成xDR单据的准确性。
在一种可能的设计中，控制服务器接收来自第二服务器的终端设备的IP地址和第二服务器的IP地址；根据终端设备的IP地址与第二服务器的IP地址的对应关系，生成第一锚点信息，通过生成第一锚点信息使得终端设备的IP报文分发给第二服务器处理，提高生成xDR单据的准确性。
在另一种可能的设计中，第一锚点信息包括第二锚点信息，控制服务器确定从第二锚点信息中是否查找到终端设备的IP地址；当从第二锚点信息中未查找到终端设备的IP地址时，向第二锚点信息中添加终端设备的IP地址与第二服务器的IP地址的对应关系得到第一锚点信息。通过确定从第二锚点信息中是否查找到终端设备的IP地址，保障终端设备所对应的锚 点服务器的唯一性，从而提高报文转发的准确性。
在另一种可能的设计中，终端设备的IP地址为第一IP地址或第二IP地址。控制服务器接收来自第二服务器的控制面信息，控制面信息包括终端设备的第一IP地址和第二IP地址，第一锚点信息包括第一IP地址、第二IP地址与第二服务器的IP地址的对应关系。在双栈情况下，通过建立终端设备的双IP地址与第二服务器的对应关系，这样终端设备无论使用哪一个IP地址来发送报文，均可以从第一锚点信息中查找到终端设备的IP地址，保障报文转发的准确性。
在另一种可能的设计中，控制服务器可以记录接收到终端设备的IP地址和第二服务器的IP地址对应的锚点时间，该锚点时间可以为接收到终端设备的IP地址和第二服务器的IP地址的第一时间点，也可以为记录终端设备的IP地址与第二服务器的IP地址的对应关系到第二锚点信息中的第二时间点，也可以为其他时间点。通过记录锚点时间，保障锚点信息的时效性。
在另一种可能的设计中，控制服务器接收第二服务器的IP地址和终端设备的IP地址之后，可以对第一锚点信息中的终端设备的IP地址和第二服务器的IP地址的对应关系进行更新。例如，可以修改终端设备的IP地址和第二服务器的IP地址对应的锚点时间。通过更新终端设备的IP地址和第二服务器的IP地址的对应关系，保障第一锚点信息的有效性。
在另一种可能的设计中，当锚点时间到当前时间点的时间间隔超过预设阈值，也即终端设备的IP地址和第二服务器的IP地址的对应关系未被更新的时长超过预设阈值时，说明在这段时间间隔内第二服务器都没有处理终端设备发送的IP报文，控制服务器可以删除第一锚点信息中终端设备的IP地址与第二服务器的IP地址的对应关系。通过删除一定时间内没有上传报文的终端设备的锚点信息，保障第一锚点信息的时效性，减少信息冗余，提高报文处理效率。
在另一种可能的设计中，在DPI系统处理终端设备的IP报文的过程中，控制服务器可以对终端设备的会话状态进行监控，当检测到终端设备的会话状态为断开状态时，控制服务器删除第一锚点信息中终端设备的IP地址与第二服务器的IP地址的对应关系。在终端设备的会话断开时，通过删除终端设备的IP地址与第二服务器的IP地址的对应关系，减少第一锚点信息中的冗余信息，从而提高报文处理效率。
在另一种可能的设计中，控制服务器接收来自第一服务器的终端设备的IP地址和第一服务器的IP地址；当从第一锚点信息中查找到终端设备的IP地址时，丢弃接收到的终端设备的IP地址和第一服务器的IP地址。保障第一锚点信息中终端设备对应的锚点服务器的唯一性，从而提高报文转发的准确性。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
如图1所示，图1是一种报文采集系统的示意图。该系统可以包括基站101、DPI系统102和网关103。其中，网关103可以为服务网关(serving gateway，SGW)或UPF实体，DPI系统102部署在基站101和网关103之间。本系统不仅可以应用于4G网络的IP报文的采集，也可以应用于5G网络的IP报文的采集。当该系统应用于4G网络的IP报文的采集时，图1中的基站101可以为演进型网络基站(E-UTRAN NodeB，eNodeB)，网关103可以为SGW。当该系统应用于5G网络的IP报文的采集时，图1中的基站101可以为5G基站(NR NodeB，gNodeB)，网关103可以为UPF实体。本方案不仅适用于4G网络的S1-U接口，也适用于4G网络的S5/S8接口，5G网络的N3或N9接口。DPI系统可以收集SGW或UPF实体采集的IP报文生成xDR单据。
如图2所示，图2是一种DPI系统的结构示意图。DPI系统可以包括汇聚交换机和多个DPI服务器。DPI系统通过物理链路分光后接入汇聚交换机，然后汇聚交换机将接收到的IP报文进行汇聚分流。当DPI系统中包括多个DPI服务器时，需要将接入的IP报文分流到不同的DPI服务器，各个DPI服务器基于接收到的IP报文生成xDR单据。DPI服务器将xDR单据发送到业务分析系统，业务分析系统基于xDR话单生成网络的关键质量指标(key quality indicators，KQI)，以对网络质量进行监控。
DPI系统的xDR单据是基于终端设备定义的，即一个终端设备完整的行为生成一张xDR单据，而终端设备在移动的过程中，IP报文可能切换到不同的网元。由于汇聚交换机仅仅具备基于网元的分发能力，而不具备基于终端设备的分发能力，所以一个终端设备无法分发到同一个DPI服务器。
如图3所示，很多终端设备已经支持IPv4/IPv6双栈。同一个终端设备在进行数据业务时，会同时使用IPv4和IPv6两个IP地址。其中，IPv4/IPv6双栈是指一个节点同时使用IPv4和IPv6协议栈，在该场景下，节点是指终端设备或应用服务器。IPv6与IPv4相比，传输层的传输控制协议(transmission control protocol，TCP)、用户数据报协议(user datagram protocol，UDP)、流控制传输协议(stream control transmission protocol，SCTP)等协议完全一致，双栈节点既能与支持IPv4协议的节点通信，又能与支持IPv6协议的节点通信。
因而，在终端设备移动场景下或使用双栈场景下，为了保证xDR单据的准确性，需要保障一个终端设备的IP报文完整分发到服务器集群中同一个DPI服务器中。当前DPI系统一般都是通过汇聚交换机基于网元进行分流，汇聚交换机仅具备基于外层IP地址进行汇聚分流的能力，无法基于隧道内的终端设备的IP地址进行汇聚分流。由于同一终端设备在不同的网元之间移动或者使用IPv4/IPv6双栈等原因，可能导致一个终端设备的同一业务的IP报文被分发到不同的DPI服务器，影响基于IP报文生成的xDR单据的准确性。
如图4所示，图4是本申请实施例提供的一种报文处理系统的架构示意图。该报文处理系统包括汇聚交换机、服务器集群、控制服务器和转发交换机。其中，汇聚交换机可以接收多条链路上的报文，并将报文分发给服务器集群中的DPI服务器。服务器集群包括多个DPI 服务器(DPI服务器1、DPI服务器2、……、DPI服务器N)。每个DPI服务器可以包括状态监控模块、识别解析模块和分发执行模块。其中，状态监控模块用于采集终端设备的IP地址和DPI服务器的IP地址，并向控制服务器上报终端设备的IP地址和DPI服务器的IP地址。分发执行模块可以用于接收汇聚交换机发送的IP报文，或者接收控制服务器下发的锚点信息，根据锚点信息执行转发IP报文或处理IP报文。识别解析模块可以用于根据接收到的IP报文进行识别和协议解析。
控制服务器也可以称为策略控制服务器，控制服务器可以包括策略控制模块，该策略控制模块用于接收DPI服务器上报的终端设备的IP地址和DPI服务器的IP地址，并保存第一次接收到终端设备的报文的DPI服务器的IP地址，建立该DPI服务器的地址与终端设备的IP地址的对应关系，生成锚点信息，然后向服务器集群广播锚点信息，使得服务器集群中每个DPI服务器根据锚点信息转发IP报文或处理IP报文。转发交换机是一个逻辑概念，物理实体可以是单独的交换机，也可以复用汇聚交换机，用于执行服务器集群内DPI服务器之间的报文的二层包转发。
可选的，该报文处理系统还可以包括终端设备，该终端设备可以用户设备(user equipment，UE)、蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、掌上电脑(personal digital assistant，PDA)和/或用于通信的任意其它适合设备等等。终端设备通过多条链路(例如图4中的链路1、链路2、链路3和链路4)、经过汇集交换机向DPI服务器发送IP报文。
以下通过实施例详细介绍各个功能实体或功能模块的作用，此处不再赘述。
如图5所示，图5是本申请实施例提供的一种报文处理方法的流程示意图，本申请实施例中的步骤至少包括：
S501，控制服务器生成第一锚点信息。
其中，第一锚点信息可以包括终端设备的IP地址与第二服务器的IP地址的对应关系。第二服务器可以为接收到所述终端设备第一次发送的IP报文的服务器，也即锚点服务器。其中，终端设备第一次发送的报文可以是针对同一业务的第一个报文，也可以是针对多个业务的第一个报文，也可以是在一个或多个发送周期内的第一个报文，也可以是在一个预设时间段内的第一个报文等等。第一锚点信息可以为锚点信息表或锚点信息映射函数等等。
可选的，第一锚点信息包括第二锚点信息，也即第二锚点信息包含第一锚点信息中的部分或全部信息。控制服务器可以预先保存第二锚点信息，控制服务器接收来自第二服务器的终端设备的IP地址和第二服务器的IP地址之后，如果从第二锚点信息中未查找到所述终端设备的IP地址，表示该终端设备的IP报文第一次被第二服务器采集到，服务器集群中的其他服务器都没有采集到终端设备的IP报文，因此第二服务器为该终端设备对应的锚点服务器，控制服务器根据该终端设备的IP地址和第二服务器的IP地址的对应关系，生成第一锚点信息。例如，控制服务器可以向第二锚点信息中添加终端设备的IP地址和第二服务器的IP地址的对应关系以得到第一锚点信息。
可选的，控制服务器可以记录接收到所述终端设备的IP地址和所述第二服务器的IP地址对应的锚点时间。其中，该锚点时间可以为接收到所述终端设备的IP地址和所述第二服务器的IP地址的第一时间点，也可以为记录终端设备的IP地址与第二服务器的IP地址的对应关系到第二锚点信息中的第二时间点，也可以为其他时间点。
需要说明的是，控制服务器也可以采用相同的方法向第二锚点信息中添加其他终端设备 的IP地址和其他服务器的IP地址的对应关系。随着需要上传报文的终端设备的数量的增多，可以记录更多的终端设备的IP地址以及对应的锚点服务器的IP地址，从而生成第一锚点信息。
S502，控制服务器广播第一锚点信息。
可选的，控制服务器可以向DPI系统中的所有服务器广播第一锚点信息，DPI系统中的第一服务器和第二服务器接收到第一锚点信息之后，保存第一锚点信息。
S503，第一服务器接收来自终端设备的第一报文，基于第一报文确定所述终端设备的IP地址。
其中，第一报文可以为IP报文，所述IP报文可以为数据面报文。
可选的，第一服务器可以通过汇聚交换机接收来自终端设备的第一报文。其中，汇聚交换机负责接入S1-U或者N3接口的IP报文，并配置基于网元IP地址对的分发规则。S1-U接口为4G网络基站(eNodeB)与SGW之间的接口，N3接口为5G网络基站(gNodeB)与UPF实体之间的接口。首先，终端设备向汇集交换机发送第一报文，汇聚交换机接收到终端设备发送的第一报文之后，基于配置的网元IP地址对的分发规则，将接收到的第一报文分发到服务器集群的第一服务器。
可选的，第一服务器接收到第一报文之后，可以根据第一报文确定终端设备的IP地址。其中，第一报文中包含GPRS隧道协议(GPRS tunneling protocol，GTP)隧道两端的网元信息。例如，如图6所示，图6是一种GTP隧道描述的示意图。隧道外层的IP地址为网元的IP地址，而隧道内层的IP地址为终端设备的IP地址或服务器的IP地址。第一服务器可以根据第一报文的发送方向，确定终端设备的IP地址。例如，如果该第一报文是由eNodeB发往SGW，或者gNodeB发往UPF实体，则GTP隧道内层的源IP地址为终端设备的IP地址。如果该第一报文是由SGW发往eNodeB，或者UPF实体发往gNodeB，则GTP隧道内层的目的IP地址为终端设备的IP地址。
S504，第一服务器基于所述终端设备的IP地址和第一锚点信息，确定是否由所述第一服务器处理所述第一报文。其中，所述第一锚点信息包括所述终端设备的IP地址与第二服务器的IP地址的对应关系。
可选的，第一服务器可以从第一锚点信息中查找所述终端设备的IP地址，当从第一锚点信息中查找到所述终端设备的IP地址时，说明终端设备第一次发送的IP报文已经被采集到，确定所述终端设备的IP地址对应的第二服务器的IP地址是否与第一服务器的IP地址相同，若第二服务器的IP地址与第一服务器的IP地址相同，也即第一服务器和第二服务器为同一个服务器，确定由第一服务器处理所述第一报文。如果第二服务器的IP地址是否与第一服务器的IP地址不相同，确定由第二服务器处理所述第一报文。
S505，当所述第一服务器的IP地址与所述第二服务器的IP地址不相同时，第一服务器根据所述第二服务器的IP地址向所述第二服务器转发所述第一报文。
可选的，当所述第一服务器的IP地址与所述第二服务器的IP地址不相同时，表示第一服务器和第二服务器不是同一个服务器，由于第二服务器是终端设备对应的锚点服务器，第一服务器需要将第一报文转发给第二服务器。具体的，第一服务器可以从预设的IP地址与MAC地址的对应关系中查找与所述第二服务器的IP地址对应的所述第二服务器的MAC地址；将所述第二IP报文的目的地址修改为所述第二服务器的MAC地址；根据所述第二服务器的MAC地址，向所述第二服务器发送所述第一IP报文。
可选的，第一服务器转发给第二服务器的第一报文可以携带指示信息，所述指示信息用 于指示该第一报文是由第二服务器处理。第二服务器接收到第一报文之后，根据所述指示信息，确定该第一报文是由第二服务器处理。
可选的，第二服务器接收到第一服务器转发的第一报文之后，首先基于第一报文确定终端设备的IP地址。然后根据终端设备的IP地址和预先保存的第一锚点信息，确定是否由第二服务器处理第一报文，当从第一锚点信息中查找到终端设备的IP与第二服务器的IP地址的对应关系时，第二服务器确定该第一报文是由第二服务器处理。
可选的，第一服务器可以向控制服务器发送终端设备的IP地址和第一服务器的IP地址。控制服务器接收到终端设备的IP地址和第一服务器的IP地址之后，可以从第一锚点信息中查找到终端设备的IP地址，并且该终端设备的IP地址对应第二服务器，说明第二服务器是终端设备对应的锚点服务器。在第一服务器与第二服务器不是同一个服务器情况下，控制服务器可以丢弃接收到的终端设备的IP地址和第一服务器的IP地址。
第二服务器接收到第一服务器转发的第一报文之后，对第一报文进行解析，并基于终端设备发送的第一报文和其他IP报文生成xDR单据，然后向业务分析系统发送xDR单据，业务分析系统接收到xDR单据之后，基于xDR单据生成网络的关键质量指标KQI，以便对网络质量进行监控。
S506，当所述第一服务器的IP地址与所述第二服务器的IP地址相同时，第一服务器对第一报文进行处理。
可选的，当所述第一服务器的IP地址与所述第二服务器的IP地址相同时，表示第一服务器和第二服务器是同一个服务器，第一服务器也是终端设备对应的锚点服务器，终端设备发送的第一报文可以由第一服务器处理。第一服务器可以对第一报文进行解析，并基于所述终端设备发送的第一报文和其他IP报文生成xDR单据，然后向业务分析系统发送xDR单据，业务分析系统接收到xDR单据之后，基于xDR单据生成网络的关键质量指标KQI，以便对网络质量进行监控。
可选的，第一服务器在确定第一报文由第一服务器处理之后，可以向控制服务器发送第一服务器的IP地址和终端设备的IP地址。控制服务器接收第一服务器的IP地址和终端设备的IP地址之后，可以从第一锚点信息中查找到终端设备的IP地址，并且终端设备的IP地址对应第二服务器，说明第二服务器是终端设备对应的锚点服务器。在第一服务器与第二服务器为同一个服务器情况下，可以对第一锚点信息中的终端设备的IP地址和第二服务器的IP地址的对应关系进行更新。例如可以修改终端设备的IP地址和所述第二服务器的IP地址对应的锚点时间。
进一步的，控制服务器可以确定锚点时间到当前时间点的时间间隔是否超过预设阈值，当锚点时间到当前时间点的时间间隔超过预设阈值，也即终端设备的IP地址和第二服务器的IP地址的对应关系未被更新的时长超过预设阈值时，说明在这段时间间隔内第二服务器都没有处理终端设备发送的IP报文，控制服务器可以删除第一锚点信息中所述终端设备的IP地址与第二服务器的IP地址的对应关系。
可选的，控制服务器更新完成第一锚点信息中的终端设备的IP地址和第二服务器的IP地址的对应关系之后，可以向第一服务器或第二服务器广播更新后的终端设备的IP地址和第二服务器的IP地址的对应关系，以便第一服务器或第二服务器对自己保存的第一锚点信息中的终端设备的IP地址和第二服务器的IP地址的对应关系进行更新。或者，控制服务器也可以向第一服务器或第二服务器广播更新后的第一锚点信息，以便第一服务器或第二服务器对第一锚点信息中的全部信息进行更新。
可选的，在DPI系统处理终端设备的IP报文的过程中，控制服务器可以对终端设备的会话状态进行监控，当控制服务器检测到所述终端设备的会话状态为断开状态时，控制服务器可以删除所述第一锚点信息中所述终端设备的IP地址与所述第一服务器的IP地址的对应关系。当检测到所述终端设备的会话状态为连接状态时，可以保持所述第一锚点信息中所述终端设备的IP地址与所述第一服务器的IP地址的对应关系。
在本申请实施例中，第一服务器通过第一锚点信息确定第一报文是由第一服务器处理还是转发给第二服务器，使得终端设备的报文分发给同一个服务器处理，不仅减少了报文转发的数量，节省网络流量，而且提高了生成xDR单据的准确性。
上述实施例主要介绍第一服务器和第二服务器如何根据第一锚点信息转发或处理报文，下面介绍主要介绍控制服务器如何生成第一锚点信息。下述实施例生成的第一锚点信息可以应用于图5所示的实施例中。
如图7所示，图7是本申请实施例提供的一种报文处理方法的流程示意图，本申请实施例中的步骤至少包括：
S701，第二服务器接收来自终端设备的第二报文，基于所述第二报文确定所述终端设备的IP地址。
其中，第二报文可以为IP报文，所述IP报文可以为数据面报文。
本步骤中第二服务器接收来自终端设备的第二报文的具体实现方式与上一实施例中第一服务器接收来自终端设备的第一报文的方法类似，以及本步骤中第二服务器基于第二报文确定终端设备的IP地址的具体实现方式与上一实施例中第一服务器基于第一报文确定终端设备的IP地址的方法也是类似的，具体参见步骤S503，此处不再赘述。
S702，第二服务器向控制服务器发送终端设备的IP地址和第二服务器的IP地址。
可选的，控制服务器预先已保存第二锚点信息，第二锚点信息可以是控制服务器预先广播给第二服务器的。所述第二锚点信息可以为空集，也可以包含第一锚点信息的部分信息。第二服务器在确定所述终端设备的IP地址之后，可以确定从第二锚点信息中是否查找到所述终端设备的IP地址，当从所述第二锚点信息中未查找到所述终端设备的IP地址时，表示该终端设备的IP报文第一次被第二服务器采集到，服务器集群中其他服务器都没有采集到该终端设备的IP报文。其中，第二报文可以是终端设备针对同一业务发送的第一个报文，也可以是终端设备针对多个业务发送的第一个报文，也可以是终端设备在一个或多个发送周期内发送的第一个报文，也可以是终端设备在一个预设时间段内发送的第一个报文等等。接收到第二报文的第二服务器为该终端设备对应的锚点服务器。通过上述判断第二服务器可以向控制服务器发送所述终端设备的IP地址和所述第二服务器的IP地址。
S703，控制服务器生成第一锚点信息。
可选的，控制服务器接收到来自所述第二服务器的所述终端设备的IP地址和所述第二服务器的IP地址之后；根据所述终端设备的IP地址和所述第二服务器的IP地址生成第一锚点信息。
进一步的，控制服务器预先已保存第二锚点信息，控制服务器接收到来自所述第二服务器的所述终端设备的IP地址和所述第二服务器的IP地址之后，确定从第二锚点信息中是否查找到所述终端设备的IP地址，如果从所述第二锚点信息中未查找到所述终端设备的IP地址，控制服务器可以向第二锚点信息中添加所述终端设备的IP地址与所述第二服务器的IP地址的对应关系，得到所述第一锚点信息。
可选的，控制服务器可以记录接收到所述终端设备的IP地址和所述第二服务器的IP地址对应的锚点时间，该锚点时间可以为接收到所述终端设备的IP地址和所述第二服务器的IP地址的第一时间点，也可以为记录终端设备的IP地址与第二服务器的IP地址的对应关系到第二锚点信息中的第二时间点，也可以为其他时间点。
需要说明的是，控制服务器也可以采用相同的方法向第二锚点信息中添加其他终端设备的IP地址和其他服务器的IP地址的对应关系。随着需要上传报文的终端设备的数量的增多，可以记录更多的终端设备的IP地址以及终端设备对应的锚点服务器的IP地址，从而得到第一锚点信息。
其中，第一锚点信息可以包括终端设备的IP地址、所述第二服务器的IP地址与时间点的对应关系。例如，第一锚点信息可以为锚点信息表或锚点信息映射函数。如表1所示，锚点信息表可以包括DPI服务器1的IP1地址、终端设备1的IP2地址与时间1的对应关系，以及DPI服务器2的IP3地址、终端设备2的IP4地址与时间2的对应关系。

表1
可选的，在用户双栈上网场景下，一个终端设备包括两个IP地址(例如IPv4和IPv6)。所述终端设备的IP地址为第一IP地址或第二IP地址，控制服务器可以接收来自第二服务器的控制面信息，所述控制面信息包括所述终端设备的第一IP地址和第二IP地址，所述第一锚点信息包括所述第一IP地址、所述第二IP地址与所述第二服务器的IP地址的对应关系。这样，终端设备无论使用第一IP地址或第二IP地址来发送报文，均可以从第一锚点信息中查找到终端设备的IP地址。
例如，如表2所示，第一锚点信息可以包括DPI服务器1的IP1地址、终端设备1的IP2地址、终端设备1的IP5地址与时间1的对应关系，以及DPI服务器2的IP3地址、终端设备2的IP4地址、终端设备2的IP6地址与时间2的对应关系。
Figure PCTCN2021137102-appb-000002
表2
可选的，在DPI系统处理终端设备的IP报文的过程中，控制服务器可以对终端设备的会话状态进行监控，当检测到所述终端设备的会话状态为断开状态时，控制服务器删除所述第一锚点信息中所述终端设备的IP地址与所述第二服务器的IP地址的对应关系。当检测到所述终端设备的会话状态为连接状态时，维持所述第一锚点信息中所述终端设备的IP地址与所述第二服务器的IP地址的对应关系。
S704，控制服务器广播第一锚点信息。
可选的，控制服务器可以向DPI系统中的所有服务器广播第一锚点信息，DPI系统中的第一服务器和第二服务器接收到第一锚点信息之后，保存第一锚点信息。
S705，第二服务器根据第一锚点信息，对第二报文进行处理。
具体的，第二服务器接收控制服务器广播的第一锚点信息之后，可以根据第一锚点信息以及第二报文对应的终端设备的IP地址，确定第二报文是否由第二服务器处理。由于第一锚点信息中已经存在终端设备的IP地址与第二服务器的IP地址的对应关系，因此可以确定第二报文是由第二服务器处理。并且通过第一锚点信息，可以确定终端设备之后发送的IP报文(包括上述实施例中的第一报文)均可以由第二服务器处理。
其中，第二服务器处理第二报文的方法与前一实施例中第一报文处理的方式相同，此处不再赘述。
在本申请实施例中，控制服务器通过收集第二服务器的IP地址和终端设备的IP地址生成第一锚点信息，使得服务器集群中所有服务器可以根据第一锚点信息将终端设备的IP报文转发给同一个服务器处理，不仅减少了报文转发的数量，节省网络流量，而且提高了生成xDR单据的准确性。
