Description

域名解析方法及装置
本申请要求于2016年03月31日提交中国专利局、申请号为201610202667.9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
本专利申请涉及互联网技术，尤其涉及一种域名解析方法及装置。
背景技术
域名系统(Domain Name System，DNS)是Internet的基础协议，用以完成域名到网络之间互联的协议(Internet Protocol，IP)地址的翻译工作。DNS服务器具有以下两种功能：一是保存有该网络中所有主机的域名和对应IP地址；二是将域名转换为IP地址。其中，将域名映射为IP地址的过程就称为“域名解析”。一个域名可对应一个或多个IP地址。
通常，用户在浏览器的地址栏输入某网站的域名时，浏览器就将该域名发送给预设的DNS服务器。DNS服务器解析该域名得到IP地址。对于一些大型网站的域名(如www.le.com)大多对应多个IP地址，可从这多个IP地址中任意选取一个IP地址返回给用户，以使用户通过该IP地址访问相应的服务器。然而，如果返回给用户的IP地址对应的服务器当前负载较重，势必会使得服务器响应缓慢，相应地，终端设备访问网络的速度也较慢，降低了用户的网络体验。
发明内容
本发明部分实施例的目的在于，提供一种域名解析方法及装置，以实现在终端设备发送域名解析请求时，将负载最少的服务器的IP地址反馈给终端设备，从而提高终端设备访问网络的速度，提升用户的网络体验。

在一个实施例中，所述选取所述多个服务器当中负载最少的服务器的处理包括：从预定的监控服务器分别获取所述多个服务器的负载量；选取负载最少的服务器。
在一个实施例中，所述负载量通过下载速度、终端的连接数量以及下载响应时长中的至少一个获得。
根据本发明的另一方面，还提供一种域名解析装置，包括：请求接收模块，用于接收终端设备发送的域名解析请求；域名及地址获取模块，用于从所述域名解析请求中获取域名信息，并获取所述域名信息对应的多个服务器的IP地址；服务器选取模块，用于选取所述多个服务器当中负载最少的服务器；地址发送模块，用于将所述负载最少的服务器的IP地址发送至所述终端设备，以使所述终端设备访问所述负载最少的服务器。

服务器选取单元，用于选取负载最少的服务器。
在一个实施例中，所述负载量通过下载速度、终端的连接数量以及下载响应时长中的至少一个获得。
根据本发明部分实施例提供的域名解析方法及装置，通过接收终端设备发送的域名解析请求，进一步从域名解析请求中获取域名信息，并获取域名信息对应的多个服务器的IP地址，选取这多个服务器中负载最少的服务器，实现了将负载最少的服务器的IP地址反馈给终端设备，从而提高了终端设备访问网络的速度，提升了用户的网络体验。

具体实施方式
本发明部分实施例的基本构思是，提供一种域名解析的技术方案。具体来说，首先，接收终端设备发送的域名解析请求；其次，从域名解析请求中获取域名信息，并获取域名信息对应的多个服务器的IP地址，进一步从获取的多个服务器中选取负载最少的服务器，从而实现了将负载最少的服务器的IP地址反馈给终端设备，进而为终端设备提供了一个快速且顺畅的网络环境，提升了用户的网络体验。
下面结合附图详细描述本发明部分的示例性实施例域名解析方法及装置。
实施例一
图1是示出根据本发明实施例一的域名解析方法的流程图。可在例如DNS服务器上执行该方法。
参照图1，在步骤S110，接收终端设备发送的域名解析请求。
当用户通过终端设备访问网络时，需要输入待访问的网站的域名，例如www.le.com，才能够访问该网站的服务器。用户首先通过终端设备向DNS服务器发送域名解析请求，域名解析请求用于通过DNS服务器对域名进行解析。
在步骤S120，从所述域名解析请求中获取域名信息，并获取所述域名信息对应的多个服务器的IP地址。
在具体的实现方式中，接收到域名解析请求之后，可以先检测DNS缓存中是否存在域名解析请求的域名的记录，即执行DNS缓存查找，从缓存中查找该域名的记录。如果在DNS缓存中不存在该域名解析请求的域名的记录，则通过DNS服务器对域名解析请求的域名进行解析。当然，在接受到域名解析请求之后，也可以直接通过DNS服务器对域名解析请求的域名进行解析，从而得到多个服务器的IP地址。如果在DNS缓存中存在该域名解析请求的域名的记录，则在DNS缓存中存有该域名对应的IP地址。这里，该IP地址可以是多个。那么可直接从DNS缓存中获取多个服务器的IP地址。
在步骤S130，选取所述多个服务器当中负载最少的服务器。
举例来说，前述多个服务器的IP地址包括有1.1.1.1和1.1.1.2两个IP地址，其中，IP地址是1.1.1.1的服务器当前负载最少，那么，1.1.1.1就是DNS服务器选取的最优结果，即负载最少的服务器。
在步骤S140，将所述负载最少的服务器的IP地址发送至所述终端设备，以使所述终端设备访问所述负载最少的服务器。
本发明实施例提供的域名解析方法，通过接收终端设备发送的域名解析请求，进一步从域名解析请求中获取域名信息，并获取域名信息对应的多个服务器的IP地址，选取这多个服务器中负载最少的服务器，实现了将负载最少的服务器的IP地址反馈给终端设备，从而提高了终端设备访问网络的速度，提升了用户的网络体验。
实施例二
图2是示出根据本发明实施例二的域名解析方法的流程图，所述实施例可视为图1的又一种具体的实现方案。可在如图4所示的域名解析装置上执行该方法。
参照图2，在步骤S210，接收终端设备发送的域名解析请求。
在步骤S220，从所述域名解析请求中获取域名信息，并获取所述域名信息对应的多个服务器的IP地址。
这里，步骤S210和步骤S220分别与上述实施例一中步骤S110和步骤S120处理方式相同，具体可参见上述S110和S120的步骤内容，在此不再赘述。
其中，步骤S230和S240可以为上述实施例一中步骤130的细化，具体如下：
在步骤S230，从预定的监控服务器分别获取所述多个服务器的负载量。
在具体的实现方式中，可预先设定专门的监控服务器，由预设的监控服务器周期性地向各个服务器发送负载状态请求消息，各个服务器将各自当前的负载量的信息返回给监控服务器。上述处理还可由DNS服务器本身完成。如果是预设的监控服务器，则需要DNS服务器从监控服务器处获取各个服务器的负载量的信息。依据各个服务器的负载量的信息选择负载最少的服务器为用户提供网络服务。此外，还可存储上述各个 服务器的负载量，并根据各个服务器在每个周期的反馈更新存储的负载量。
需要说明的是，上述负载量可通过下载速度、终端的连接数量以及下载响应时长中的至少一个获得，但不限于此。举例来说，假设“下载响应时长(1.1.1.1)”＝20s，“下载响应时长(1.1.1.2)＝10s”，这里，下载响应时长越长，表明服务器的负担越重。再比如，“终端的连接数量(1.1.1.1)”＝1000个，“终端的连接数量(1.1.1.2)＝500个”，终端的连接数量越多，表明服务器的负担越重。因此，可依据如终端的连接数量、下载响应时长、下载速度等能够反映服务器的负载状态的数据，来确定各个服务器的负载量。
在步骤S240，选取负载最少的服务器。
在获得上述各个服务器的负载量之后，可根据负载量对各个服务器进行排序，从中选取负载最少的服务器。
在步骤S250：将所述负载最少的服务器的IP地址发送至所述终端设备，以使所述终端设备访问所述负载最少的服务器。
这里，步骤S250与上述实施例一中步骤S140处理方式相同，具体可参见上述S140的步骤内容，在此不再赘述。
本发明部分实施例提供的域名解析方法，具有如下技术效果：
一方面，通过预定的监控服务器获取多个服务器的负载量，从而为选取负载最少的服务器提供判断依据，更加方便、快捷地将负载最少的服务器的IP地址发送给终端设备。从而终端设备通过负载最少的服务器访问网络，极大地提高了访问网络的速度，提升了用户的网络体验；
另一方面，基于下载速度、终端的连接数量以及下载响应时长等，多维度的反映服务器的负载状态的数据获得服务器的负载量，从而准确地选取负载最少的服务器。

服务器选取单元3302用于选取负载最少的服务器。
