Description

数据传输方法、装置、系统、电子设备及计算机程序产品 技术领域
本发明涉及互联网技术领域，特别涉及数据传输方法、装置、系统、电子设备及计算机程序产品。
背景技术
在文件传输协议(FTP：File Transfer Protocol)的Passive模式下，客户端与FTP源站服务器21端口建立一条控制连接，用于客户端与FTP源站服务器之间的控制命令传输，控制命令如登录、认证、查看目录等控制命令；客户端与FTP源站服务器非21端口建立一条数据连接，用于客户端与FTP源站服务器之间的数据上传与下载。图1为本发明现有技术的数据传输的方法示意图，如图1所示，当只有单一FTP代理服务器时，通过在FTP源站服务器侧的配置文件中指定FTP代理服务器的IP地址及非21端口，并将指定的FTP代理服务器IP地址及非21端口信息经由控制连接发送给客户端，以使客户端基于指定的FTP代理服务器IP地址及非21端口实现数据传输。
现有技术不足在于：
在以传输控制协议(TCP：Transmission Control Protocol)代理技术为基础的应用分发网络(ADN：Application Delivery Network)环境，以及FTP的Passive模式下，当存在多个入口服务器时，无法通过在配置文件中指定入口服务器的IP地址及端口的方式实现数据传输，而是用域名代替所指定的入口服务器的IP地址，由FTP源站服务器通过DNS解析的方式获取入口服务器的IP地址。但是，当FTP源站服务器与客户端不在同一区域时，DNS服务器解析相同的域名会返回不同的IP地址，如客户端接入FTP源站服务器侧的入口服务器，导致FTP上传/下载的速度较慢。
发明内容
本发明实施例提出了数据传输方法、装置、系统、电子设备及计算机程序产品，主要用以解决FTP上传/下载速度较慢的技术问题。
在一个方面，本发明实施例提供了一种数据传输方法，应用于ADN网络中，用于FTP数据传输，该方法包括：
当接收到FTP源站服务器根据数据传输请求消息发送的数据传输应答消息时，根据所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息建立与FTP源站服务器的数据连接；
将所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息变更为FTP代理服务器自身的IP地址及端口信息，并将变更后的IP地址及端口信息携带在所述数据传输应答消息中发送给客户端。
在另一个方面，本发明实施例提供了一种数据传输装置，其特征在于，应用于ADN网络中，用于FTP数据传输，该装置包括：
数据连接模块，用于当接收到FTP源站服务器根据数据传输请求消息发送的数据传输应答消息时，根据所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息建立与FTP源站服务器的数据连接；
变更模块，用于将所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息变更为FTP代理服务器自身的IP地址及端口信息，并将变更后的IP地址及端口信息携带在所述数据传输应答消息中发送给客户端。
在另一个方面，本发明实施例提供了一种数据传输系统，应用于ADN网络中，用于FTP数据传输，该系统包括：
客户端，用于当接收到来自FTP代理服务器的数据传输应答消息时，根据所述数据传输应答消息中的FTP代理服务器的IP地址及端口信息，建立与所述FTP代理服务器的数据连接；
FTP代理服务器，用于当接收到FTP源站服务器根据数据传输请求消息发送的数据传输应答消息时，根据所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息建立与FTP源站服务器的数据连接，以及
将所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息变更为FTP代理服务器自身的IP地址及端口信息，并将变更后的IP地址及端口信息携带在所述数据传输应答消息中发送给客户端；
FTP源站服务器，用于接收上传文件的数据，或者将下载文件的数据发送给所述FTP代理服务器。
在另一个方面，本发明实施例提供了一种电子设备，应用于ADN网络中，用于FTP数据传输，所述电子设备包括：
存储器，一个或多个处理器；以及
一个或多个模块，所述一个或多个模块被存储在所述存储器中，并被配置成由所述一个或多个处理器执行，所述一个或多个模块包括用于执行上述方法中各个步骤的指令。
在另一个方面，本发明实施例提供了一种与电子设备结合使用的计算机程序产品，所述计算机程序产品包括计算机可读的存储介质和内嵌于其中的计算机程序机制，所述计算机程序机制包括用于执行上述方法中各个步骤的指令。
有益效果如下：
当ADN网络中存在多个FTP代理服务器时，FTP代理服务器接收来自FTP源站服务器的数据传输应答消息，并通过将数据传输应答消息中的FTP源站服务器的IP地址及端口信息变更为FTP代理服务器自身的IP地址及端口信息的方式，准确定位到客户端用于建立数据连接的FTP代理服务器，从而建立客户端、FTP代理服务器及FTP源站服务器三者之间的数据连接，达到加速FTP上传/下载速度的技术效果。
附图说明
下面将参照附图描述本发明的具体实施例，其中：
图1为本发明现有技术的数据传输的方法示意图；
图2为本发明实施例一中数据传输的方法原理图；
图3为本发明实施例二中数据传输的方法流程图；

发明人在发明过程中注意到：
当存在多个入口服务器时，通过在FTP源站服务器侧配置域名的方式，由FTP源站服务器侧的DNS服务器解析该配置域名并将解析得到的入口服务器IP地址及端口信息发送给客户端，使得客户端只能根据该IP地址及端口信息接入FTP源站服务器侧的入口服务器，而非就近接入客户端侧的入口服务器，导致FTP上传/下载的速度较慢。
针对上述不足，本发明实施例提出了在存在多个ADN入口服务器的网络环境下，当ADN入口服务器接收到客户端发送的下载/上传文件的数据传输请求消息时，将接收到的数据传输请求消息发送给FTP源站服务器，以及当接收到FTP源站服务器根据数据传输请求消息发送的数据传输应答消息时，根据所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息建立与FTP源站服务器的数据连接，同时，将所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息变更为FTP代理服务器自身的IP地址及端口信息，并将变更后的IP地址及端口信息携带在所述数据传输应答消息中发送给客户端，以实现FTP数据的加速传输。
为了便于本发明的实施，下面以实例进行说明。

步骤201：当接收到FTP源站服务器根据数据传输请求消息发送的数据传输应答消息时，根据所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息建立与FTP源站服务器的数据连接。
步骤202：将所述数据传输应答消息中的FTP源站服务器的IP地址及端口信息变更为FTP代理服务器自身的IP地址及端口信息，并将变更后的IP地址及端口信息携带在所述数据传输应答消息中发送给客户端。
在步骤201中，在进行FTP数据传输时，客户端通过智能DNS解析出就近的FTP代理服务器(即ADN网络中的ADN入口服务器)的IP地址，建立客户端与FTP代理服务器之间的控制连接，并经由所建立的控制连接，将下载/上传文件的数据传输请求消息发送给该FTP代理服务器。同时，FTP代理服务器建立与FTP源站服务器之间的控制连接，以使FTP代理服务器将数据传输请求消息经由所建立的控制连接，发送给FTP源站服务器，再由FTP源站服务器根据监听到的数据传输请求消息得到数据传输应答消息，并将该数据传输应答消息发送给FTP代理服务器。
其中，数据传输请求消息为经由控制连接传输的控制命令，如上传/下载文件的请求消息等，数据传输应答消息为经由控制连接传输的控制命令，如上传/下载文件的应答消息等。
FTP代理服务器通过对该数据传输应答消息进行解析得到FTP源站服务器的IP地址及非21端口(如1500-1520端口中的任一端口)信息，并根据该FTP源站服务器的IP地址及非21端口信息建立与FTP源站服务器之间的数据连接，同时，监听来自客户端非21端口的上传文件的数据流，以及来自FTP源站服务器非21端口的下载文件的数据流等。
在步骤202中，FTP代理服务器将修改后的IP地址及端口信息携带在所 述数据传输应答消息中发送给客户端之后，客户端根据FTP代理服务器的IP地址及端口信息建立与FTP代理服务器非21端口之间的数据连接，以使FTP代理服务器将来自客户端的上传文件的数据经由所建立的数据连接发送给FTP源站服务器，或者将来自FTP源站服务器的下载文件的数据经由所建立的数据连接发送给客户端。
进一步地，本发明实施例还包括：
当监测到所述FTP代理服务器与客户端，或者与所述FTP源站服务器之间的TCP连接断开时，断开所述FTP代理服务器与所述FTP源站服务器，或者与所述客户端之间的TCP连接。
FTP代理服务器实时监测与客户端之间的TCP连接状态，以及与FTP源站服务器之间的TCP连接状态，以保证FTP代理服务器与客户端之间，以及FTP代理服务器与FTP源站服务器端之间TCP连接状态的同步性。即，当FTP代理服务器智能监测到与客户端之间的TCP连接状态出现故障时，及时断开FTP代理服务器与FTP源站服务器之间的TCP连接，当FTP代理服务器智能监测到与FTP源站服务器之间的TCP连接状态出现故障时，及时断开FTP代理服务器与FTP源站服务器之间的TCP连接。
进一步地，本发明实施例还包括：
当监测到所述FTP源站服务器出现故障时，与所述FTP源站服务器的备份FTP源站服务器建立控制连接和数据连接。
FTP代理服务器智能监测FTP源站服务器的端口状态，当监测到FTP源站服务器的端口出现故障时，将与FTP源站服务器建立的控制连接和数据连接断开，并切换到FTP备份服务器。可见，FTP代理服务器通过实时监测FTP源站服务器端口状态的方式，保证FTP源站服务器出现故障时能够实现及时地切换。
本发明实施例二以基于包含多个入口服务器的ADN网络，实现FTP数据上传/下载的具体应用场景为例，对本发明实施例二进行详细描述。
实施例二、
图3示出了本发明实施例二中数据传输的方法流程图，如图3所示，包括：
步骤301：FTP源站服务器侧预先配置用于与客户端建立数据连接的FTP源站服务器自身的IP地址及端口信息。FTP源站服务器通常被配置为Passive模式，在Passive模式下，在FTP源站服务器侧的配置文件中指定FTP源站服务器自身的IP地址和端口号。图4示出了本发明实施例二中数据传输的流程示意图，如图4所示，FTP源站服务器假定所指定的IP地址为1.0.0.1，端口号为1500-1520，即FTP源站服务器自身的IP地址及端口号。
步骤302：配置入口服务器，用于监听来自客户端，以及FTP源站服务器的数据流。配置ADN网络侧入口服务器的监听端口，每个入口服务器的21端口用于监听来自客户端21端口的下载/上传文件的请求消息，以及来自FTP源站服务器21端口的下载/上传文件的应答消息等；每个入口服务器的1500-1520端口用于监听来自客户端1500-1520端口的上传文件的数据流，以及来自FTP源站服务器1500-1520端口的下载文件的数据流等。
步骤303：客户端2与入口服务器建立控制连接，入口服务器与FTP源站服务器建立控制连接。客户端2获取ADN网络侧智能DNS根据来自客户端2的访问请求消息解析出的就近入口服务器的IP地址，根据该入口服务器IP地址建立与该入口服务器之间的控制连接，即连接该入口服务器的21端口(如1.0.0.1：21)，该入口服务器与FTP源站服务器建立控制连接，即连接FTP源站服务器的21端口。
步骤304：客户端2将下载/上传文件的请求消息经由入口服务器发送给FTP源站服务器，FTP源站服务器将其自身的IP地址及端口信息携带在下载/上传文件的应答消息中发送给入口服务器。客户端2将下载/上传文件的请求消息经由所建立的控制连接发送给入口服务器，入口服务器将该下载/上传文件的请求消息转发给FTP源站服务器。当FTP源站服务器的监听端口监听到 该下载/上传文件的请求消息时，将其自身的IP地址及端口信息携带在下载/上传文件的应答消息中，经由已建立的控制连接发送给入口服务器。
步骤305：入口服务器修改应答消息中的IP地址及端口信息，并将修改后的IP地址及端口信息携带在应答消息中返回给客户端2。当入口服务器监听到来自FTP源站服务器的应答消息时，根据应答消息中FTP源站服务器的IP地址及端口信息(如1.0.0.1：1500)建立与FTP源站服务器之间的数据连接，以使入口服务器将来自客户端2的上传文件的数据流经由所建立的数据连接发送给FTP源站服务器，以及将来自FTP源站服务器的下载文件的数据流发送给客户端2。同时，将应答消息中FTP源站服务器的IP地址及端口信息修改为入口服务器自身的IP地址及端口信息(如1.0.0.2：1500)，并将修改后的IP地址及端口信息携带在应答消息中返回给客户端2。
步骤306：客户端2根据来自入口服务器的IP地址及端口信息建立数据连接，以实现数据的加速传输。客户端2接收经由控制连接返回的应答消息，并根据应答消息中的IP地址及端口信息(如1.0.0.2：1500)建立与入口服务器之间的数据连接，以使客户端2将上传文件的数据流经由入口服务器发送给FTP源站服务器，以及接收来自FTP源站服务器的下载文件的数据流。
步骤307：入口服务器监测与客户端2之间的TCP连接状态，以及与FTP源站服务器之间的TCP连接状态，以保证客户端2与FTP源站服务器端TCP连接状态的同步性。当入口服务器智能监测到与客户端2之间的TCP连接状态出现故障时，及时断开入口服务器与FTP源站服务器之间的TCP连接，当入口服务器智能监测到与FTP源站服务器之间的TCP连接状态出现故障时，及时断开入口服务器与FTP源站服务器之间的TCP连接。
步骤308：入口服务器监测FTP源站服务器的端口状态，以保证FTP源站服务器出现故障时能够实现及时切换。入口服务器智能监测FTP源站服务器的端口状态，当监测到FTP源站服务器的端口出现故障时，将与FTP源站服务器建立的控制连接和数据连接断开，并切换到FTP备份服务器。
