具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
本申请中术语“第一”“第二”“第三”等字样用于对作用和功能基本相同的相同项或相似项进行区分，“第一”、“第二”和“第三”之间不具有逻辑或时序上的依赖关系，也不对数量和执行顺序进行限定。
本申请将围绕可包括多个设备、组件、模块等的系统来呈现各个方面、实施例或特征。应当理解和明白的是，各个系统可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
另外，在本申请实施例中，“示例的”、“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，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。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
本申请中，“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表 达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
本申请实施例中，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。
下面结合图1，对适用于本申请实施例的场景进行详细描述。
图1是适用于本申请实施例的应用场景100的示意图。如图1所述，应用场景100中包括终端设备101、代理网关102、代理服务器103和目的服务器104。终端设备与目的服务器之间可以通过代理网关和代理服务器进行报文的交互。例如，代理网关和代理服务器将终端设备发送的请求报文转发至目的服务器，然后将目的服务器发送的响应报文转发至终端设备。其中，代理网关可以为终端设备中的一个软件模块，或者也可以为独立于终端设备的装置，本申请对此不作限定。应理解，当代理网关为终端设备中的一个软件模块时，代理网关与终端设备之间的报文交互为终端设备中的不同软件模块之间的报文传递。
应理解，代理服务器(proxy server)用于代理网络用户去取得网络信息。可以形象的将代理服务器理解为网络信息的中转站，是个人网络和互联网服务商之间的中间代理机构，负责转发合法的网络信息，对转发进行控制和登记。代理服务器作为一种既是服务器又是客户机的中间程序，主要用于转发客户系统的网络访问请求。但是，代理服务器不只是简单地向真正的因特网服务器转发请求，它还可以控制用户的行为，对接收到的客户请求进行决策，并根据过滤规则对用户的请求进行过滤。
通过代理服务器，网络管理员可以实现比用包过滤路由器更严格的安全策略，不同于使用通用的包过滤路由器来管理通过防火墙的因特网服务流向，代理服务器通过在代理网关上为每项需要的应用安装专用的代码(代理服务)来工作。如果网络管理员没有为某一特殊服务安装代理服务代码，该服务就不会被支持，也不会通过防火墙转发相应的客户请求。并且，这种代理服务代码能被配置称仅支持某项服务的网络管理员认为可以接受的那部分特征，而不支持其他特征。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，第五代(5th Generation，5G)网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
为了便于更好地理解本申请技术方案，下面将对本申请技术方案涉及相关技术进行介绍。
1、网络诊断工具(packet internet groper，ping)：是一种计算机网络工具，用来确定本地主机是否能与另一台主机成功交换(发送与接收)数据包，再根据返回的信息，就可以推断传输控制协议/互联协议(transmission control protocol/internet protocol，TCP/IP)参数是否设置正确，以及运行是否正常、网络是否通畅。其中，交换的数据包可以称为ping 报文，而ping报文又可以包括请求报文(ping request报文)和响应报文(ping reply报文)。即根据ping报文的传输时间和成功响应的次数，可以估算出丢失数据包率(丢包率)和数据包往返时间。
2、互联网控制报文协议(internet control message protocol，ICMP)、用户数据报协议(user datagram protocol，UDP)、TCP等：均是TCP/IP协议簇的子协议，其中，ICMP用来传递控制消息，不用来传输用户数据，而TCP和UDP是用来传输用户数据的。
3、ICMP报文：包括两种类型的报文，为ICMP差错报告报文和ICMP询问报文。ping报文属于ICMP询问报文中的一种，可以用来测量信息经过某个服务器的时延和丢包率。
4、压栈：也可以称为进栈或入栈，是指将新元素插入一个栈。而栈(stack)又名堆栈，是一种运算受限的线性表，限定仅在表尾进行插入和删除操作的线性表，表尾被称为栈顶，相对地，另一端称为栈低。压栈就是把新元素放到栈顶元素的上面，使之成为新的栈顶元素。此外，从一个栈删除元素又称作出栈或退栈，是把栈顶元素删除掉，使其相邻的元素称为新的栈顶元素。
5、NAT转换表：网络地址转换协议(network address translation，NAT)表，可以理解为服务器在对报文进行处理、转发时，将会在NAT转换表中记录报文的处理、转发过程，用于后续相关报文的处理。或者还可以理解，NAT转换表主要用于完成数据报文从一个网络到另一个网络时，报文的IP地址和端口号映射到另外的IP地址和端口号。
本申请提出了一种代理服务器处理ping报文的方法，使得用户在通过代理服务器上网时，也能够通过ping报文来测量信息经过代理服务器的时延和丢包率。
图2示出了本申请提出的一种处理ping报文的方法的示意性流程图，该方法200包括：
S201，代理网关获取第一ping请求报文，第一ping请求报文的源因特网协议(sourceinternet protocol，SIP)地址为终端设备的IP地址，目的因特网协议(destinationinternet protocol，DIP)地址为目的服务器的IP地址。

S203，代理网关向代理服务器发送第二ping请求报文，相应的，代理服务器接收第二ping请求报文。

另一种可能的实现方式中，代理服务器也可以同时在数据库中查询或匹配第二ping请求报文的元数据以及代理网关的IP地址，在确定数据库中包括第二ping请求报文的元数据以及代理网关的IP地址后，根据第二ping请求报文，生成上述第三ping请求报文。
应理解，上述第二ping请求报文的元数据可以为终端设备的标识信息，该终端设备的标识信息包括于ping报文中，例如，第一ping请求报文至第三ping请求报文以及第一ping响应报文至第三ping响应报文的净荷中均包括该终端设备的标识信息。可选的，终端设备的标识信息可以称为用户标识。

可选的，在本申请实施例中，在代理服务器根据第三ping响应报文，生成第一ping 响应报文之前，代理服务器可以查询代理网关的认证信息，或者也可以查询NAT转换表，来确定是否可以转发该ping报文。
应理解，代理服务器查询代理网关的认证信息可以是，代理服务器在数据库中查询代理网关的认证信息，例如，当第三ping响应报文的净荷包括代理网关的认证信息和代理网关的IP地址时，代理服务器查询数据库中是否包括代理网关的认证信息。
还应理解，代理服务器查询NAT转换表可以是，代理服务器根据第三ping响应报文的SIP地址和DIP地址，确定NAT转换表中包括该SIP地址和DIP地址的转换信息。

因此，通过上述代理服务器对ping报文进行转发，从而能够通过ping报文来测量信息经过代理服务器的时延和丢包率。
可选的，在本申请实施例中，代理服务器可以为替换为网络服务提供(point of presence，POP)点，POP点可以称为入网点。
应理解，在本申请的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
