在本申请一个典型的配置中，终端或可信方等均包括一个或多个处理器(例如，中央处理器(Central Processing Unit，CPU)、输入/输出接口、网络接口和内存。内存可能包括计算机可读介质中的非永久性存储器，随机存取存储器(Random Access Memory，RAM)和/或非易失性内存等形式，如只读存储器(Read Only Memory，ROM)或闪存(Flash Memory)。内存是计算机可读介质的示例。
计算机可读介质包括永久性和非永久性、可移动和非可移动媒体可以由任何方法或技术来实现信息存储。信息可以是计算机可读指令、数据结构、程序的模块或其他数据。计算机的存储介质的例子包括，但不限于相变内存(Phase-Change Memory，PCM)、可编程随机存取存储器(Programmable Random Access Memory，PRAM)、静态随机存取存储器(Static Random-Access Memory，SRAM)、动态随机存取存储器(Dynamic Random Access Memory，DRAM)、其他类型的随机存取存储器(RAM)、只读存储器(ROM)、电可擦除可编程只读存储器(Electrically-Erasable Programmable Read-Only Memory，EEPROM)、快闪记忆体或其他内存技术、只读光盘只读存储器(Compact Disc Read-Only Memory，CD-ROM)、数字多功能光盘(Digital Versatile Disc,DVD)或其他光学存储、磁盒式磁带，磁带磁盘存储或其他磁性存储设备或任何其他非传输介质，可用于存储可以被计算设备访问的信息。

当然，本领域技术人员应能理解上述设备仅为举例，其他现有的或今后可能出现的设备如可适用于本申请，也应包含在本申请保护范围以内，并在此以引用方式包含于此。
本申请示出了一种确定DPI设备的传输时延信息的方法，该方法应用于网络业务系统，该网络业务系统通常包括用户设备、DPI设备和网络设备，由三端配合完成。非示例性地，图1示出本申请的一个典型场景，一个或多个用户设备的传输数据经由DPI设备发送至网络设备，网络设备将其经由DPI设备转发至用户设备等，在此，DPI设备主要用于根据事先定义的策略对该传输数据进行过滤控制，完成所在链路的业务精细化识别、业务流量流向分析、业务流量占比统计、业务占比整形、以及应用层拒绝服务攻击、对病毒或木马进行过滤和滥用P2P的控制等功能。换言之，DPI设备对链路上的流量进行采集与识别，并将满足其他系统所需的流量或分析统计数据分发至网络设备。所述DPI设备对数据的处理会对数据传输造成传输时延，该对应传输时延信息若处于可允许的时延区间，则当前DPI设备的数据处理比较正常等，若该传输时延信息处于可允许的时延区间之外，则当前DPI设备的数据处理功能可能出现异常。本申请通过确定DPI设备的传输时延信息来确定数据传输过程中是否存在异常 等。
本申请实施例中，该网络设备可以是独立的服务器，也可以是服务器组成的服务器网络或服务器集群，例如，本申请实施例中所描述的计算机设备，其包括但不限于计算机、网络主机、单个网络服务器、多个网络服务器集或多个服务器构成的云服务器。其中，云服务器由基于云计算(Cloud Computing)的大量计算机或网络服务器构成。
本领域技术人员可以理解，图1中示出的应用环境，仅仅是与本申请方案一种应用场景，并不构成对本申请方案应用场景的限定，本领域普通技术人员可知，随着网络业务场景的演变和新网络业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
参考图1示出的系统拓扑，图2示出根据本申请一个方面的一种确定DPI设备的传输时延信息的方法，应用于网络设备，所述网络设备位于网络业务系统，所述网络业务系统中还包括用户设备和DPI设备，所述用户设备经由所述DPI设备与所述网络设备通信，所述方法包括步骤S101、步骤S102、步骤S103以及步骤S104。在步骤S101中，网络设备获取所述用户设备发送的、经由所述DPI设备转发的传输数据信息以及所述传输数据信息对应的起始传输时刻；在步骤S102中，网络设备调节所述传输数据信息在所述网络设备的转发时延信息；在步骤S103中，网络设备将所述传输数据信息经由所述DPI设备返回至所述用户设备，并获取所述DPI设备的结束传输时刻；在步骤S104中，网络设备根据所述起始传输时刻、所述转发时延信息以及所述结束传输时刻确定所述DPI设备的传输时延信息。
具体而言，在步骤S101中，网络设备获取所述用户设备发送的、经由所述DPI设备转发的传输数据信息以及所述传输数据信息对应的起始传输时刻。例如，用户设备中安装有网络设备对应的应用(如第三方应用、小程序或者插件等)，所述用户设备通过该应用向网络设备发送对应传输数据，该传输数据先被发送至DPI设备进行数据处理，经DPI设备进行检测处理后发送至网络设备。用户设备发送该传输数据时，还同时向网络设备发送该传输数据的起始传输时刻，在一些情形下，该起始传输时刻包括在用户设备端该传输数据的第一个字 节被读取的开始传输的时刻，在另一些情形下，所述起始传输时刻包括在用户设备端该传输数据的最后一个字节被读取完毕准备发送的起始传输时刻等。在此，为了方便计算，我们取传输数据最后一个字节被读取完毕准备发送的时刻作为对应起始传输时刻为例阐述以下实施例，本领域技术人员应能理解，将用户设备端传输数据的第一个字节被读取的开始传输的时刻作为对应的起始传输时刻的情形同样适用于以下该等实施例，同样应包含于本申请保护范围以内。
在步骤S102中，网络设备调节所述传输数据信息在所述网络设备的转发时延信息。例如，所述转发时延信息用于指示所述传输数据信息在所述网络设备的转发时长等，如以网络设备开始接收所述传输数据信息的起始时间开始计时至对应网络设备将该传输数据信息转发完毕为止，该计时所得到的转发时长即为对应的转发时延信息。所述转发时延信息可以是网络设备端根据随机数取得，也可以是根据管理人员的设置操作所获取的。通常情形下，该转发时延信息小于对应的转发时长阈值等，该转发时长阈值用于指示用户设备端的数据传输异常对应的时长，若用户设备端发送对应传输数据信息后在转发时长阈值内未接收到对应的转发的数据信息等，则用户设备确定本次数据传输过程异常等。
在步骤S103中，网络设备将所述传输数据信息经由所述DPI设备返回至所述用户设备，并获取所述DPI设备的结束传输时刻。例如，所述网络设备将对应传输数据信息经由DPI设备返回至用户设备，所述用户设备记录该传输数据的结束传输时刻，与起始传输时刻相对应地，在一些情形下，所述结束传输时刻包括所述传输数据信息被所述用户设备完全接收对应的时刻，在另一些情形下，所述结束传输时刻包括所述传输数据信息被所述用户设备开始接收对应的时刻。在此，为了方便计算，我们取所述传输数据信息被所述用户设备开始接收对应的时刻作为对应结束传输时刻为例阐述以下实施例，本领域技术人员应能理解，将所述传输数据信息被所述用户设备完全接收对应的时刻作为对应的结束传输时刻的情形同样适用于以下该等实施例，同样应包含于本申请保护范围以内。
在步骤S104中，网络设备根据所述起始传输时刻、所述转发时延信息以及所述结束传输时刻确定所述DPI设备的传输时延信息。例如，网络设备获取对应到对应的起始传输时刻，所述转发时延信息以及对应结束传输时刻后，可以根据对应信息计算出所述DPI设备的传输时延信息，在此，考虑到数据在链路中的传输过程中时长相较于DPI设备的处理时长较小，我们忽略链路过程中的传输时长，将整个流程过程中除网络设备转发时延之外计算得到的时间差作为DPI设备的传输时延信息等。例如，假设所述起始传输时刻为T1，所述结束传输时刻为T2，所述转发时延信息为t1，则对应传输时延信息为t2＝(T2-T1)-t1，即通过传输过程中的整个时长减去网络设备端的转发时延信息得到DPI设备的传输时延信息。
在一些实施方式中，在步骤S102中，网络设备记录接收所述传输数据信息对应的接收传输时刻，根据所述接收传输时刻及对应的转发时延信息确定所述传输数据信息对应的转发传输时刻；其中，在步骤S103中，包括：在所述转发传输时刻将所述传输数据信息经由所述DPI设备返回至所述用户设备。例如，所述接收传输时刻包括所述网络设备开始接收所述传输数据的时刻，所述转发传输时刻包括所述网络设备结束转发所述传输数据的时刻，在一些情形下，所述传输数据的数据量较小，对应传输速率较快，所述传输数据信息本身被读取或者转发的时长远小于所述转发时延信息，则可以忽略该传输数据信息被接收或者转发时数据读取所耗的时间，直接可以计算得到对应转发传输时刻。如假设接收传输时刻为T3，对应转发传输时刻T4＝T3+t1，换言之，将转发传输时刻加上对应转发时延信息得到对应的转发传输时刻。则网络设备计算得到对应的转发传输时刻后，控制该传输数据信息在网络设备的停留时长，在时间到达对应转发传输时刻T4时，将所述传输数据信息经由DPI设备返回至所述用户设备。本申请能够灵活控制网络设备对传输数据信息的转发时延信息从而更加精确确定各环节的时延信息，有利于网络业务系统运转的稳定和效率等。
在一些实施方式中，所述数据的数据量较大，数据帧较长，且对应的数据传输速率较慢，则对应的数据传输时长会对时延的计算产生影响，我们要将该数据传输时长排除之后计算更加精确的时延信息。在步骤S102中，网络设备获 取所述传输数据信息的数据传输时长；根据所述数据传输时长及所述转发时延信息确定所述传输数据信息对应的数据停留时长；根据所述接收传输时刻、所述数据传输时长以及所述数据停留时长确定对应的转发传输时刻。例如，当传输数据的数据传输时长相对于转发时延信息并不是刻意忽略不计等，如所述传输数据的数据传输时长大于或等于所述转发时延信息的忽略阈值(如二十分之一等)，则网络设备获取所述传输数据信息的数据传输时长，如网络设备可以接收对应用户设备或者DPI设备发送的关于所述传数据信息的数据传输时长，又如网络设备可以根据传输数据信息的传输速率及数据帧长度计算该传输数据信息的数据传输时长等，如在一些实施方式中，所述获取所述传输数据信息的数据传输时长，包括：获取所述传输数据信息的数据帧长度及对应的传输速率，根据所述数据帧长度及所述传输速率确定所述传输数据信息的数据传输时长。例如，网络设备通过数据帧长度除以对应传输速率可以得到该传输数据信息的数据传输时长等，所述网络设备获取该数据传输时长后，通过接收传输时刻、转发时延信息等确定对应的数据停留时长，并基于该数据停留时长等确定对应的转发传输时刻等。在此，所述转发传输时刻包括所述传输数据信息的第一个字节开始被网络设备接收对应的时刻，所述转发传输时刻包括所述传输数据信息第一个字节被所述网络设备转发对应的时刻，假设对应的数据传输时长为t0，则对应的传输输数据信息在网络设备的数据停留时长t3＝t1-2*t0；随后，对应的转发传输时刻T4＝T3+t0+t3，根据该转发传输时刻和数据传输时长可以确定网络设备结束转发数据的结束转发时刻T5＝T4+t0＝T3+t1等。
在一些实施方式中，根据数据传输时长可以确定更加精确的传输时延信息，如在步骤S104中，网络设备根据所述起始传输时刻、所述转发时延信息、所述结束传输时刻以及所述数据传输时长确定所述DPI设备的传输时延信息。例如，去除传输流程中的多个数据传输时长，能够更加精确的确定DPI设备的传输时延信息，如传输流程中所述传输数据信息两次经过所述DPI设备，则需要在前述基础上减去四个数据传输时长对应的时间，换言之，所述DPI设备的传输时延信息t2’＝(T2-T1)-t1-4*t0，该传输时延信息用于表征DPI设备对所述传输数据信息进行处理的时长。当然，在一些情形下，需要排除数据在各链 路传输过程中的异常情形，则需要计算各个环节的时延信息，除了DPI设备端的传输时延之外，还有用户设备-DPI设备、DPI设备-网络设备、网络设备-DPI设备以及DPI设备-网络设备之间的传输链路对应的时延信息等，将该链路中传输时延信息统称为其他时延信息。如在一些实施方式中，所述方法还包括步骤S105(未示出)，在步骤S105中，网络设备获取所述DPI设备对应的接收数据时刻及发送数据时刻；在步骤S104中，根据所述起始传输时刻、所述转发时延信息、所述结束传输时刻、所述数据传输时长以及所述接收数据时刻及所述发送数据时刻确定所述DPI设备的传输时延信息及其他时延信息，其中，所述其他时延信息包括所述传输数据在除所述DPI设备及所述网络设备之外其他传输过程中的时延信息。例如，DPI设备记录对应的接收数据时刻及对应发送数据时刻，对应接收数据时刻包括所述DPI设备开始接收传输数据信息的时刻，如该DPI设备开始接收到传输数据信息的第一个字节对应的时刻，对应从用户设备端或者网络设备端接收数据时刻分别为T6；所述发送数据时刻包括该DPI设备发送传输数据信息完毕对应的时刻，如该DPI设备将传输数据信息的最后一个字节发送完毕的时刻，对应向网络设备或者用户设备端发送数据时刻分别为T7。在此，所述接收数据时刻与所述发送数据时刻为数据在同侧通过该DPI的时刻等。则对应DPI设备的传输时延信息t2”＝T7-T6-2*t0，对应其他时延信息t4＝(T2-T1)-t1-2*t2”。本申请能够更加精确地确定信息传输过程中各个过程中的时延信息，从而达到对网络业务系统中信息传输过程中的精准控制，对于数据传输异常能够快速定位并处理等。
在一些实施方式中，所述方法还包括步骤S106(未示出)。在步骤S106中，网络设备基于所述转发时延信息验证所述用户设备的时延异常处理的可靠性。例如，用户设备设置有数据传输异常对应的转发时长阈值等，若传输数据信息的转发总时长超过该转发时长阈值T0，即T2-T1＞T0，则用户设备确定当前传输数据信息的传输过程异常，可能会发生丢包或者数据拦截等，则用户设备向网络设备再次发送传输数据信息或者向网络设备发送异常提示信息提示所述网络设备本次传输数据存在异常等。通过该转发时长阈值和传输时延信息可以计算得到网络设备端的转发时延信息的正常区间，如小于或等于T0-t2等，若 将网络设备的转发时延信息设置为大于或等于T0-t2，可以验证所述用户设备的时延异常处理功能是否可靠。如将所述转发时延信息设置为T0，若在一定时间内网络设备接收到用户设备重新发送的传输数据信息或者接收用户设备发送的异常提示信息，则网络设备确定用户设备的时延异常处理功能正常；若一定时间内网络设备未接收到用户设备重新发送的传输数据信息且为接收到用户设备发送的异常提示信息，则网络设备确定用户设备的时延异常处理功能出现异常，向用户设备发送对应时延异常处理功能异常的提示信息等，提示用户设备对应的用户对用户设备的相应功能减刑检修等。
