一种数据处理方法及装置
交叉引用
本申请引用于2019年02月20日递交的名称为“一种数据处理方法及装置”的第201910126092.0号中国专利申请，其通过引用被全部并入本申请。
技术领域
本申请涉及数据处理技术领域，尤其涉及一种数据处理方法及装置。
背景技术
在数据信息的传递过程中，为了缓解源站的压力，通常可以在客户端设备和源站之间设置边缘设备，边缘设备可以接收客户端设备发送的数据信息，并对数据信息进行处理(比如，加速处理、过滤处理、压缩处理等)，将处理后的数据信息发送给目标源站，该过程即为对数据信息进行调度的过程。域名调度***(Domain Name System，DNS)为对数据信息进行调度的一个常用的应用场景，具体地说，边缘设备可以在获取到目标源站的域名信息后，根据目标源站的域名信息确定目标源站的IP地址和目的端口，从而将处理后的数据信息发送给目标源站。若确定得到的目标源站的IP地址和目的端口中任一个信息有误，则客户端设备发送的数据信息即无法被成功转发至目标源站上，从而会使得用户的体验感较差。
为了确定目标源站的IP地址和目的端口，现有技术通常采用如下方式：预先通过人工获取与边缘设备连接的源站的信息，比如源站的数量、源站的IP地址、源站的端口等，进而在边缘设备上设置与源站的信息对应的虚拟IP地址和端口。如此，在实施过程中，边缘设备可以通过客户端设备发送的数据信 息到达的虚拟IP地址和端口，确定目标源站的IP地址和目的端口。然而，采用上述方式，由于虚拟IP地址和端口是根据人工获取到的源站的信息进行设置的，若源站的信息发生变化，则需要人工重新获取变化后的源站的信息，并重新设置虚拟IP地址和端口，操作较为复杂；且，客户端设备发送的数据信息中目的端口可以是通过实时协商确定的，通过预先设置好的端口对数据信息进行调度时，预先设置好的端口中可能不包括目的端口，从而使得调度出错。因此，采用现有技术的方式可能会使得对数据信息进行调度的灵活性较差。
综上，目前亟需一种数据处理方法及装置，用以提高对数据信息调度的灵活性。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作详细描述，显然，所描述的实施例仅仅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做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
图1a为本申请实施例适用的一种***架构示意图，使用该***架构可以实现对客户端设备发送的数据信息进行调度，图1a所示意的***架构可以有多种可能，比如可以为DNS***，或者可以为内容分发网络(Content Delivery Network，CDN)***，具体不作限定。
如图1a所示，该***架构中可以包括至少一个客户端设备(比如图1a所示意出的客户端设备101、客户端设备102、客户端设备103和客户端设备104)、边缘设备200和多个源站(比如图1a所示意出的源站301、源站302和源站303)。其中，客户端设备101～客户端设备104可以位于同一个区域，边缘设备200可以负责管理位于该区域内的客户端设备101～客户端设备104。具体地说，边缘设备200可以通过接入网络而与该区域的每一个客户端设备通信，比如，边缘设备200可以通过有线方式(网线、光纤等)与客户端设备101～客户端设备104通信，或者也可以通过无线方式(蓝牙、无线网络通信技术(Wireless Fidelity，WIFI等)与客户端设备101～客户端设备104通信。
具体实施中，客户端设备可以为终端设备，比如手机、笔记本电脑、台式机等。客户端设备可以具有多种功能，比如，路由功能、记录功能和共识功能等。具体地说，客户端设备可以向边缘设备传输数据信息或请求消息，且可以接收边缘设备反馈的信息；或者，客户端设备可以记录历史上所有的数据信息的传输过程，比如传输数据信息的时间、传输数据信息的数据量等；或者，客户端设备可以与同区域或不同区域的客户端设备通信，以共享数据信息。实际应用中，路由功能是至少一个客户端设备中的每个客户端设备必须具有的功能，而其它功能可由本领域技术人员根据实际需要进行设置。
以客户端设备101向源站301发送数据信息为例，边缘设备200接收到客户端设备101发送的数据信息后，可以对数据信息进行处理，并将处理后的数据信息发送给源站301，从而实现对数据信息的调度过程。其中，对数据信息进行处理的方式可以有多种，比如，若边缘设备200检测到数据信息的数据量较大，则可以对数据信息进行压缩，通过将压缩后的数据信息发送给源站301，可以提升数据信息发送的速度；或者，若边缘设备200检测到数据信息中包含敏感信息，则可以对数据信息进行加密，通过将加密后的数据信息发送给源站301，可以提高数据信息的安全。此处仅为示例性描述边缘设备对数据信息进行处理的方式，并非限定采用该种方式，在具体实施中，也可以根据实际需要对数据信息进行处理，具体不作限定。
需要说明的是，图1a仅为本申请实施例适用的一种***架构的示例，可以理解的，在其它可能的示例中，适用于本申请实施例中提供的数据处理方法的***均可以为本申请实施例中的方案。在一个示例中，***架构中还可以包括多个边缘设备，多个边缘设备中的任一边缘设备可以管理多个客户端设备。举例来说，***架构中可以包括第一边缘设备～第三边缘设备，第一边缘设备可以负责管理位于区域A1内的第一客户端设备～第四客户端设备，第二边缘设备可以负责管理位于区域A2内的第五客户端设备～第六客户端设备，第三边缘设备可以负责管理位于区域A3内的第七客户端设备～第十客户端设备。
图1b为本申请实施例适用的又一种***架构示意图，与图1a中的***架构相比，图1b所示意出的***架构中还可以包括至少一个回源设备，比如图1b所示意的回源设备401、回源设备402和回源设备403。其中，至少一个回源设备可以设置在边缘设备和多个源站之间，边缘设备、回源设备和源站之间可以通过有线方式或者无线方式实现通信连接。比如，边缘设备与回源设备之间通过网线(或光纤)连接，而回源设备与源站之间通过WIFI(或蓝牙)连接；或者边缘设备与回源设备之间通过WIFI(或蓝牙)连接，而回源设备与源站之间通过网线(或光纤)连接；或者边缘设备、回源设备与源站之间均通过网线(或光纤、WIFI、蓝牙)连接，具体不作限定。
具体实施中，至少一个回源设备的设置方式可以有多种可能，在一个示例中，至少一个回源设备中的每个回源设备可以与多个源站中的每个源站一一对应设置；比如图1b所示，回源设备401可以与源站301对应设置，回源设备402可以与源站302对应设置，回源设备403可以与源站303对应设置。在又一个示例中，至少一个回源设备中的每个回源设备可以管理位于同一区域的多个源站，举例来说，***架构中可以包括第一回源设备～第三回源设备，第一回源设备可以管理位于区域B1内的第一源站～第三源站，第二回源设备可以管理位于区域B2内的第四源站，第三回源设备可以管理位于区域B3内的第五源站～第七源站。
以图1b所示意的回源设备的设置方式为例，客户端设备101向源站301发送数据信息的实现过程可以为：边缘设备200在接收到客户端设备101发送的数据信息后，可以对数据信息进行处理，并将处理后的数据信息发送给与源站301对应设置的回源设备401；相应地，回源设备401在接收到处理后的数据信息后，可以对处理后的数据信息进行逆处理，进而将逆处理得到的数据信息发送给源站301。举例来说明，若边缘设备200对数据信息进行压缩，则回源设备401可以对压缩后的数据信息进行解压缩；若边缘设备200对数据信息进行加密，则回源设备401可以对加密后的数据信息进行解密。本申请实施例 中，与源站对应的回源设备可以设置在距离源站较近的位置，通过回源设备对处理后的数据信息进行逆处理，可以使得源站接收到数据信息后直接进行后续处理，而无需进行解压缩或解密等额外的工作，从而可以减轻源站的压力。
在实际业务场景中，客户端设备发送的数据信息可以包括两种类型(为了便于描述，称为第一类型和第二类型)，第一类型的数据信息中可以封装有目标源站的域名信息，比如基于超文本传输协议(HyperText Transfer Protocol，HTTP)的数据信息；第二类型的数据信息中无法封装目标源站的域名信息，比如基于传输控制协议(Transmission Control Protocol，TCP)的数据信息、基于用户数据报协议(User Datagram Protocol，UDP)的数据信息等。针对于第一类型的数据信息，客户端设备可以在接收到数据信息后，解析数据信息得到源站的域名信息，从而通过源站的域名信息确定源站的IP地址和目的端口。然而，针对于第二类型的数据信息，由于其未封装源站的域名信息，在实际操作中，若客户端设备仅向边缘设备发送数据信息，则边缘设备无法根据数据信息获取目标源站的IP地址和目的端口，从而导致数据信息的调度过程出错。
为了解决上述问题，现有技术预先通过人工在边缘设备中设置多个虚拟IP地址和多个端口，其中，多个虚拟IP地址可以与多个源站一一对应，多个端口可以与多个源站的端口相同。在具体实施中，边缘设备可以向客户端设备同步多个虚拟IP地址与多个源站的对应关系，因此，客户端设备可以根据边缘设备同步的信息确定目标源站对应的虚拟IP地址，从而将数据信息发送至目标源站对应的虚拟IP地址上；例如，边缘设备在接收到客户端设备发送的数据信息后，可以确定数据信息中封装的目的端口(比如端口5)，并将数据信息引流至边缘设备上设置的端口5。由此可知，现有技术中边缘设备可以根据数据信息到达的虚拟IP地址和端口确定目标源站的IP地址和目的端口，从而可以将数据信息转发至目标源站上。
采用现有技术的方式，可能会存在一些问题，比如，边缘设备上需要设置和多个源站的端口相同的端口，若源站的某一个端口与边缘设备原有的端口 相同，则将边缘设备原有的端口所执行的功能弃用，从而使得边缘设备的功能受到限制；或者，边缘设备上设置的虚拟IP地址和端口均是根据人工获取到的源站的IP地址和端口进行设置的，若某一时刻源站的IP地址或端口发生变化，则边缘设备上设置的虚拟IP地址和端口可能无法进行实时更新，从而导致数据信息的调度过程出错。由此可知，采用现有技术的方案会使得对数据信息进行调度时的灵活性较差。
综上，目前亟需一种数据处理方法及装置，用以提高对数据信息调度的灵活性。
下面具体描述本申请实施例中的数据处理方法，该数据处理方法可以实现客户端设备与目标源站之间的数据信息的调度过程。
本申请实施例中，客户端设备确定与目标源站之间进行数据调度时，客户端设备可以向边缘设备发送第一数据包，第一数据包中可以包括虚拟IP地址，或者可以包括目标端口，或者还可以包括虚拟IP地址和目的端口。相应地，边缘设备在接收到客户端设备发送的第一数据包后，若第一数据包中包括虚拟IP地址，则边缘设备可以解析第一数据包，得到第一数据包对应的虚拟IP地址，并根据虚拟IP地址进行数据处理；若第一数据包中包括目的端口，则边缘设备可以解析第一数据包，得到第一数据包对应的目的端口，并根据目的端口进行数据处理；若第一数据包中包括虚拟IP地址和目的端口，则边缘设备可以解析第一数据包，得到第一数据包对应的虚拟IP地址和目的端口，并根据虚拟IP地址和目的端口进行数据处理。
下面针对于这三种可能出现的方面分别进行描述，示例一对应第一数据包中包括虚拟IP地址的方面，示例二对应第一数据包中包括目的端口的方面，示例三对应第一数据包中包括虚拟IP地址和目的端口的方面。
在示例一中，若边缘设备解析第一数据包，得到第一数据包对应的虚拟IP地址，则边缘设备可以根据第一数据包对应的虚拟IP地址，查询IP地址映射表，得到虚拟IP地址对应的目的IP地址；例如，边缘设备可以根据目的IP 地址，发送所述第一数据包。采用示例一所述的方式，边缘设备中可以设置有IP地址映射表，通过采用查询IP地址映射表的方式获取目的IP地址，边缘设备可以无需向客户端设备同步源站的信息，从而使得确定目的IP地址的过程更加灵活，进而提高对数据信息调度的灵活性。
需要说明的是，在示例一中，边缘设备在发送第一数据包时，第一数据包对应的目的端口可以为通过现有技术确定的。举一个现有技术的例子进行说明：在边缘设备接收第一数据包之前，可以通过人为的方式在边缘设备上设置与多个端口，且多个端口分别与多个源站的端口相同；在边缘设备接收到第一数据包后，可以采用现有技术的方式将第一数据包引流到边缘设备上设置的与目的源站的端口相同的端口；此时，边缘设备通过检测第一数据包到达的端口，确定第一数据包对应的目的端口(比如，第一数据包被引流至端口5，则目的端口即为端口5)。由此可知，在示例一中，边缘设备可以在解析第一数据包得到的虚拟IP地址后，查询IP地址映射表，得到目的IP地址，并可以将第一数据包到达的端口确定为目的端口，从而边缘设备可以根据目的IP地址和目的端口发送第一数据包。
在示例二中，若边缘设备解析第一数据包，得到第一数据包对应的目的端口，则边缘设备可以根据目的端口，发送第一数据包。其中，解析第一数据包得到的目的端口即为源站的目的端口，采用示例二中的方式，相比于现有技术通过静态指定目的端口的方式来说，可以无需在边缘设备上设置目的端口，从而可以支持端口需要动态协商的协议，提高对数据信息调度的灵活性。
需要说明的是，在示例二中，边缘设备在发送第一数据包时，第一数据包对应的虚拟IP地址可以为通过现有技术确定的。举一个现有技术的例子进行说明：在边缘设备接收第一数据包之前，可以通过人为的方式获取多个源站的IP地址，并在设备边缘设备中设置多个虚拟IP地址，多个虚拟IP地址与多个源站的IP地址一一对应；且边缘设备可以将该对应关系发送给客户端设备，以使客户端设备在发送第一数据包之前，可以根据目标源站确定与目标源站的 IP地址对应的虚拟IP地址，此时，客户端设备可以将虚拟IP地址封装在第一数据包后，将第一数据包发送给边缘设备。例如，边缘设备可以根据人为设定的虚拟IP地址和源站的IP地址的对应关系，确定目的IP地址。
在示例三中，若边缘设备解析第一数据包，得到第一数据包对应的虚拟IP地址和目的端口，则边缘设备可以根据第一数据包对应的虚拟IP地址和目的端口，发送第一数据包。示例三采用边缘设备解析第一数据包的方式获取虚拟IP地址和目的端口，一方面，解析第一数据包得到的目的端口即为源站的目的端口，相比于现有技术通过静态指定目的端口的方式来说，可以无需在边缘设备上设置目的端口，从而可以支持端口需要动态协商的协议，提高对数据信息调度的灵活性；另一方面，通过采用查询IP地址映射表获取目的IP地址的方式，边缘设备无需向客户端设备同步源站的信息，从而使得确定目的IP地址的过程更加灵活。
下面以示例三为例描述本申请实施例中数据处理方法的实现过程，示例一中确定目的IP地址的过程以及示例二中确定目的端口的过程可以参照示例三中的方法进行实施，不再赘述。
图2为本申请实施例提供的一种数据处理方法对应的流程示意图，如图2所示，该方法包括：
步骤201，边缘设备确定接收到客户端设备发送的第一数据包后，解析第一数据包，得到第一数据包对应的虚拟IP地址和目的端口。
此处，客户端设备发送的第一数据包中可以包括虚拟IP地址和目的端口，其中，虚拟IP地址可以为目标源站对应的虚拟IP地址。具体地说，边缘设备上可以设置有多个虚拟IP地址，多个虚拟IP地址与多个源站的IP地址一一对应，在客户端设备向边缘设备发送第一数据包之前，客户端设备可以预先确定出目标源站对应的虚拟IP地址(比如虚拟IP地址a)，从而可以将第一数据包发送至边缘设备的虚拟IP地址a上。
具体实施中，虚拟IP地址的获取方式可以有多种，在一种可能的实施例 (为便于描述，简称为实施例一)中，虚拟IP地址可以为客户端设备通过人为确定的，或者为客户端设备根据边缘设备同步的源站和虚拟IP地址的对应关系确定的。具体地说，用户可以在获取到多个源站的标识信息(即目标源站的域名信息)后，在边缘设备中设置多个虚拟IP地址，并构建多个虚拟IP地址和多个源站的域名信息的对应关系表，在该对应关系表中，每个虚拟IP地址可以对应一个源站的域名信息。同时，边缘设备可以将多个虚拟IP地址和多个源站的域名信息的对应关系表同步给客户端设备，客户端设备在确定目标源站后，可以通过人为或者自动方式，从对应关系表中确定出目标源站的域名信息对应的虚拟IP地址。
在又一种可能的实施例(为便于描述，简称为实施例二)中，虚拟IP地址可以为客户端设备根据边缘设备发送的虚拟IP地址确定的。具体地说，客户端设备在向边缘设备发送第一数据包之前，可以预先向边缘设备发送请求消息，请求消息中可以包括目标源站的域名信息；相应地，边缘设备在接收到客户端设备发送的请求消息后，可以解析该请求消息得到目标源站的域名信息，并可以根据目标源站的域名信息查询IP地址映射表，从而得到目标源站的域名信息对应的虚拟IP地址。例如，边缘设备可以向客户端设备发送响应消息，响应消息中可以包括目标源站的域名信息对应的虚拟IP地址；客户端设备在接收到边缘设备发送的响应消息后，可以解析响应消息得到虚拟IP地址，并将包含有虚拟IP地址的第一数据包发送给边缘设备。
在实施例二中，客户端设备发送的第一数据包中可以包括目标源站的IP地址对应的虚拟IP地址，而目标源站的IP地址对应的虚拟IP地址可以为客户端设备从边缘设备中预先获取的；也就是说，本申请实施例中采用客户端设备和边缘设备通信的方式来获取目标源站的IP地址对应的虚拟IP地址，相比于现有技术通过人为确定目标源站的IP地址对应的虚拟IP地址的方式来说，边缘设备可以无需向客户端设备同步多个源站的IP地址和多个虚拟IP地址的对应关系，且可以无需通过人为交互确定目标源站的IP地址对应的虚拟IP地址，从而可以 提高数据处理的灵活性，提高用户的体验。
本申请实施例中，边缘设备中可以存储有IP地址映射表，其中，IP地址映射表可以为边缘设备根据多个源站的信息自动生成的。具体地说，边缘设备在接收到多个源站的信息后，可以根据多个源站的数量，生成多个虚拟IP地址，其中，多个虚拟IP地址与多个源站一一对应。其中，多个源站的信息可以为多个源站发送的，或者也可以为回源设备发送的，每个源站的信息中可以包括源站的IP地址，或者还可以包括源站的域名信息和/或回源设备的IP地址，具体不作限定。例如，边缘设备可以根据多个源站的信息和多个虚拟IP地址，生成IP地址映射表。
基于图1a所示意的***架构，在一个示例中，IP地址映射表可以为边缘设备根据多个源站发送的信息自动生成的，每个源站发送的信息可以包括每个源站的域名信息和每个源站的IP地址。具体地说，边缘设备可以在接收到多个源站发送的多个源站的域名信息和多个源站的IP地址后，根据多个源站的IP地址生成与多个源站的IP地址一一对应的多个虚拟IP地址，进而根据多个源站的域名信息、多个源站的IP地址和多个虚拟IP地址，生成IP地址映射表。
在图1a所示意的***架构中，源站301～源站303可以分别向边缘设备200发送源站301～源站303的信息，以源站301为例，源站301可以按照预设周期或者实时检测源站301的信息(源站301的域名信息和源站301的IP地址)，若检测到源站301的信息发生变化，则可以将变化后的源站301的信息发送给边缘设备200。相应地，边缘设备200中可以设置有第一预设表格，第一预设表格中存储有多个源站的信息，若接收到源站301发送的变化后的源站301的信息，则可以对第一预设表格进行更新，比如将第一预设表格中存储的源站301的信息替换为变化后的源站301的信息。表1为一种边缘设备中第一预设表格的内容示意。
表1：一种边缘设备中第一预设表格的内容示意
源站标识 源站的域名信息 源站的IP地址
源站301 fileserver1.com 192.168.10.100
源站302 fileserver2.com 192.168.20.100
源站303 fileserver3.com 192.168.30.100
如表1所示，源站301的域名信息为fileserver1.com，IP地址为192.168.10.100；源站302的域名信息为fileserver2.com，IP地址为192.168.20.100；源站303的域名信息为fileserver3.com，IP地址为192.168.30.100。此时，边缘设备200可以根据解析第一预设表格得到的多个源站的信息，确定多个源站的数量为3，因此，边缘设备200可以在边缘设备200中设置与3个源站的IP地址一一对应的3个虚拟IP地址，比如，与源站301的IP地址对应的虚拟IP地址设置为192.168.10.1，与源站302的IP地址对应的虚拟IP地址设置为192.168.20.1，与源站303的IP地址对应的虚拟IP地址设置为192.168.30.1。例如，边缘设备200可以根据3个源站的域名信息、3个源站的IP地址和3个虚拟IP地址，生成IP地址映射表。基于表1所示意的多个源站的信息，边缘设备200生成的IP地址映射表可以为表2所示。

fileserver3.com 192.168.30.100 192.168.30.1
基于图1b所示意的***架构，在另一个示例中，IP地址映射表可以为边缘设备根据多个回源设备发送的信息自动生成的，每个回源设备发送的信息可以包括每个回源设备的IP地址、每个回源设备对应的源站的域名信息和每个回源设备对应的源站的IP地址。具体地说，边缘设备可以在接收到多个回源设备发送的信息后，根据多个回源设备对应的源站的IP地址生成与多个回源设备对 应的源站的IP地址一一对应的多个虚拟IP地址，进而根据多个回源设备的IP地址、多个回源设备对应的源站的域名信息、多个回源设备对应的源站的IP地址和多个虚拟IP地址，生成IP地址映射表。
在图1b所示意的***架构中，回源设备401～回源设备403可以按照预设周期或实时监测源站301～源站303的状态，并可以向边缘设备200发送源站301～源站303的信息，以回源设备401为例，回源设备401若检测到源站301的信息发生变化，则可以将变化后的源站301的信息发送给边缘设备200。此处描述的是回源设备401的IP地址未发生变化的情况，若回源设备401的IP地址也发生变化，则回源设备401可以将变化后的回源设备401的IP地址和变化后的源站301的信息共同发送给边缘设备200。相应地，边缘设备200中可以设置有第二预设表格，第二预设表格中存储有多个源站的信息和多个回源设备的IP地址，若接收到回源设备401发送的变化后的源站301的信息和/或回源设备401的IP地址，则边缘设备200可以对第二预设表格进行更新，比如将第二预设表格中存储的源站301的信息替换为变化后的源站301的信息，和/或，将第二预设表格中存储的回源设备401的信息替换为变化后的回源设备401的信息。表3为一种边缘设备中第二预设表格的内容示意。

源站302 fileserver2.com 192.168.20.100 回源设备402 192.168.20.10
源站303 fileserver3.com 192.168.30.100 回源设别403 192.168.30.10
如表3所示，回源设备401的IP地址为192.168.10.10，回源设备401对应的源站为源站301，源站301的域名信息为fileserver1.com，IP地址为192.168.10.100；回源设备402的IP地址为192.168.20.10，回源设备402对应的源站为源站302，源站302的域名信息为fileserver2.com，IP地址为192.168.20.100；回源设备403的IP 地址为192.168.30.10，回源设备403对应的源站为源站303，源站303的域名信息为fileserver3.com，IP地址为192.168.30.100。此时，边缘设备200可以根据解析预设表格得到的多个源站的信息，确定多个源站的数量为3，因此，边缘设备200可以在边缘设备200中设置与3个源站的IP地址一一对应的3个虚拟IP地址。例如，边缘设备200可以根据3个回源设备的IP地址、3个源站的域名信息、3个源站的IP地址和3个虚拟IP地址，生成IP地址映射表。基于表3所示意的多个源站的信息和多个回源设备的IP地址，边缘设备200生成的IP地址映射表可以为表4所示。

fileserver2.com 192.168.20.100 192.168.20.10 192.168.20.1
fileserver3.com 192.168.30.100 192.168.30.10 192.168.30.1
本申请实施例中，边缘设备可以实时接收多个源站的信息，从而可以自动设置多个虚拟IP地址和IP地址映射表，相比于现有技术通过人工方式设置虚拟IP地址的方式来说，实时性更好，且节省人力和物力。
以表2所示的IP地址映射表为例，边缘设备接收到客户端设备发送的请求消息后，若解析请求消息得到的源站的域名信息为fileserver2.com，则边缘设备可以根据表2中源站的域名信息与虚拟IP地址的对应关系，确定fileserver2.com对应的虚拟IP地址为192.168.20.1。此时，边缘设备可以向客户端设备发送响应消息，响应消息中包括虚拟IP地址(即192.168.20.1)。相应地，客户端设备在接收到响应消息后，可以将第一数据包发送给边缘设备，第一数据包中包括数据信息、虚拟IP地址192.168.20.1和目的端口。其中，数据信息可以为具体的业务信息，比如数据流、信息流等。
本申请实施例中，边缘设备可以在确定第一数据包到达边缘设备后，对 第一数据包进行解析，得到第一数据包中包括的数据信息、虚拟IP地址和目的端口。其中，解析第一数据包的方式可以有多种，例如，可以在边缘设备中编写记忆程序，该记忆程序可以驱动边缘设备存储第一数据包、第一数据包对应的目的端口和第一数据包对应的虚拟IP地址的对应关系。具体地说，边缘设备在解析第一数据包得到第一数据包中包括的数据信息、虚拟IP地址和目的端口后，边缘设备可以将第一数据包对应的虚拟IP地址和目的端口作为一条历史消息，记录在边缘设备的预设存储空间中。比如，边缘设备的预设存储空间中存储有一条历史消息“第一数据包-192.168.20.1-端口5”，则可以确定边缘设备对第一数据包进行解析，得到的第一数据包对应的虚拟IP地址为192.168.20.1，目的端口为端口5。此处，端口5即为目的端口。
例如，边缘设备可以将第一数据包中的数据信息引流到第一端口，其中，第一端口为预先从一个或多个端口中确定出的用于接收边缘设备引流的数据信息的端口。第一端口可以为固定端口，比如FTP协议对应的固定端口12，或者也可以为其它端口，比如边缘设备的原有端口中的任一个端口，具体不作限定；也就是说，边缘设备可以将第一数据包中的数据信息引流到边缘设备上的任一端口(目的端口或其它端口)。举例来说明，边缘设备中设置有端口1～端口10，已确定端口5为目的端口，若采用现有技术中的方案，则边缘设备需要将数据信息引流至端口5，而根据本申请实施例中的方案，边缘设备可以将数据信息引流至端口1～端口10中的任一端口。
以FTP协议为例，当客户端设备发送的第一数据包到达边缘设备时，客户端设备和边缘设备是通过实时协商确定目的端口的；若采用现有技术中的方案，在边缘设备上预先设置的多个端口中可能并不包括目的端口，因此，边缘设备无法将数据信息引流至目的端口上，从而使得数据信息调度的过程出错。而采用本申请实施例中的方案，在客户端设备和边缘设备实时协商确定目的端口后，边缘设备解析第一数据包得到的端口即为目的端口，此时，边缘设备可以将数据信息引流至任一端口上，即数据信息可以正常调度。
本申请实施例中，边缘设备可以将数据信息引流到边缘设备原有的一个或多个端口中的第一端口，而无需在边缘设备中设置与多个源站的端口相同的端口，从而可以避免人工获取服务器的信息，节省人力成本，提高对数据调度的灵活性。也就是说，相比于现有技术通过静态指定目的端口的方式来说，本申请实施例中的方案可以无需在边缘设备上设置目的端口，从而可以支持端口需要动态协商的协议，提高数据信息调度的灵活性。
步骤202，边缘设备根据虚拟IP地址，查询IP地址映射表，得到虚拟IP地址对应的目的IP地址。
本申请实施例中，边缘设备在确定第一数据包对应的数据信息到达第一端口后，可以查询边缘设备的预设存储空间中存储的历史消息，得到第一数据包对应的虚拟IP地址。例如，边缘设备可以根据虚拟IP地址，查询IP地址映射表，得到虚拟IP地址对应的目的IP地址，若为图1a所示意的***架构，则该目的IP地址可以为目的源站的IP地址；若为图1b所示意的***架构，则该目的IP地址可以为目的源站对应的回源设备的IP地址。
在一种可能的实施例中，边缘设备中可以设置有至少一个代理模块，至少一个代理模块中的每个代理模块均可以监控一个端口的状态，若监测某一端口的代理模块检测到该端口上有数据信息到达，则监测该端口的代理模块可以执行步骤202所示的内容。具体地说，边缘设备上可以设置有端口1～端口10，若第一端口为端口1，则边缘设备中可以仅设置有监控端口1的第一代理模块，或者也可以设置有监控端口1的第一代理模块和监控端口2～端口10的第二代理模块～第十代理模块，具体不作限定。
以监控第一端口的第一代理模块为例，若第一代理模块检测到第一数据包对应的数据信息到达第一端口，则可以从边缘设备的预设存储空间中获取第一数据包对应的历史记录。若获取到的历史记录为“第一数据包-192.168.20.1-端口5”，则第一代理模块可以确定第一数据包对应的虚拟IP地址为192.168.20.1，目的端口为端口5。例如，第一代理模块在确定第一数据包对应的虚拟IP地址 192.168.20.1后，可以查询IP地址映射表，得到虚拟IP地址192.168.20.1对应的目的IP地址。若为图1a所示意的***架构，则第一代理模块可以查询表2所示意的IP地址映射表，此时，第一代理模块可以确定虚拟IP地址192.168.20.1对应的目的IP地址为源站的IP地址192.168.20.100。若为图1b所示意的***架构，则第一代理模块可以查询表4所示意的IP地址映射表，此时，第一代理模块可以确定虚拟IP地址192.168.20.1对应的目的IP地址为回源设备的IP地址192.168.20.10。
步骤203，边缘设备根据目的IP地址和目的端口，发送第一数据包。
在一种可能的实施例中，边缘设备解析第一数据包还可以得到第一数据包对应的数据信息，相应地，边缘设备可以根据第一数据包对应的数据信息、目的IP地址和目的端口，得到第二数据包，并发送第二数据包。具体地说，边缘设备可以在得到第二数据包之前，对第一数据包对应的数据信息进行处理，得到处理后的数据信息；例如，边缘设备可以根据处理后的数据信息、目的IP地址和目的端口，封装得到第二数据包。其中，对数据信息进行处理的方式可以有多种，比如压缩处理、加速处理、加密处理等，具体不作限定。
在一个示例中，若为图1a所示意的***架构，则可以确定得到的目的IP地址为源站的IP地址，此时，边缘设备可以将第二数据包发送给目的源站。在又一个示例中，若为图1b所示意的***架构，则可以确定得到的目的IP地址为回源设备的IP地址，此时，边缘设备可以将第二数据包发送给回源设备；相应地，回源设备可以在接收到第二数据包后，根据第二数据信息、回源设备对应的源站的IP地址和目的端口，得到第三数据包，并发送第三数据包。举例来说，若边缘设备将第二数据包发送给回源设备402，则回源设备402在接收到第二数据包后，若确定第二数据包中的数据信息为边缘设备处理后的数据信息，则可以对第二数据包中的数据信息进行二次处理。为便于描述，将第一数据包中的数据信息简称为第一数据信息，将第二数据包中的数据信息简称为第二数据信息，若第二数据信息为边缘设备对第一数据信息进行压缩和/或加密得到的，则回源设备402可以对第二数据信息进行解压缩和/或解密，得到第三数据信息。 例如，回源设备402可以根据第三数据信息、回源设备402对应的源站302的IP地址和目的端口，得到第三数据包，并将第三数据包发送给源站。
本申请的上述实施例中，边缘设备确定接收到客户端设备发送的第一数据包后，对第一数据包进行解析，得到第一数据包对应的虚拟IP地址和目的端口；边缘设备可以根据虚拟IP地址，查询IP地址映射表，得到虚拟IP地址对应的目的IP地址，例如，边缘设备根据目的IP地址和目的端口，发送第一数据包。本申请实施例采用边缘设备解析第一数据包的方式获取虚拟IP地址和目的端口，一方面，解析第一数据包得到的目的端口即为源站的目的端口，相比于现有技术通过静态指定目的端口的方式来说，可以无需在边缘设备上设置目的端口，从而可以支持端口需要动态协商的协议，提高对数据信息调度的灵活性；另一方面，通过采用查询IP地址映射表获取目的IP地址的方式，边缘设备无需向客户端设备同步源站的信息，从而使得确定目的IP地址的过程更加灵活。
下面从***交互的角度描述本申请实施例中的数据处理方法，其与图2所示意的方法流程相对应。

此处，目的IP地址为目的源站的IP地址。
步骤360，边缘设备根据第一数据包对应的数据信息、目的IP地址和目标端口，生成第二数据包，并将第二数据包发送给目的源站。
其中，步骤310～步骤360中确定目的IP地址和目标端口的过程可以参照图2所示的执行过程进行实现，具体不作赘述。

步骤460，边缘设备根据第一数据包对应的数据信息、目的IP地址和目标端口，生成第二数据包，并将第二数据包发送给目的源站对应的回源设备。
步骤470，目的源站对应的回源设备根据第二数据包对应的第一目的IP地址，确定第二目的IP地址。
此处，第二目的IP地址可以为目的源站的IP地址。
步骤480，目的源站对应的回源设备根据第二数据包对应的数据信息、 第二目的IP地址和目标端口，生成第三数据包，并将第三数据包发送给目的源站。
其中，步骤410～步骤480可以参照图2所示的执行过程进行实现，具体不作赘述。
本申请实施例中，客户端设备与边缘设备之间可以存在两次通信过程，第一次通信时，客户端设备可以获取到边缘设备反馈的虚拟IP地址，第二次通信时，客户端设备可以将第一数据包通过边缘设备发送给目标源站。本申请实施例中，通过采用边缘设备解析第一数据包的方式获取虚拟IP地址和目的端口，一方面，解析第一数据包得到的目的端口即为源站的目的端口，相比于现有技术通过静态指定目的端口的方式来说，可以无需在边缘设备上设置目的端口，从而可以支持端口需要动态协商的协议，提高对数据信息调度的灵活性；另一方面，通过采用查询IP地址映射表获取目的IP地址的方式，边缘设备无需向客户端设备同步源站的信息，从而使得确定目的IP地址的过程更加灵活。
