30; 需要说明的是, 这是所提到的桌面信息不仅仅包括图像界面的桌面信息 (例如, Windows系统的桌面), 也可以包括非图像界面的桌面信息等。
步骤 S204, 接收来自远程设备 30的对被远程设备 20进行的操作信息, 并将操作 信息发送给被远程设备 20。 通过上述步骤, 在远程设备 30和被远程设备 20之间连接服务器 10, 通过该服务 器 10对远程设备 30和被远程设备 20之间的数据进行中转,改变了现有技术中直接地 端对端的架构, 为实现更加有效地远程控制提供了可能。 优选地, 在实施时, 服务器 10可以包括一个或多个数据中转站 102, 数据中转站 102用于执行上述的步骤 S102和步骤 S104, 数据中转站 102是与远程设备 30的类型 相对应的, 不同类型的远程设备 30可以对应不同的数据中转站 102。而为远程设备 30 选择中转站 102的工作可以由服务器 10来进行, 例如, 服务器 10可以选择与远程设 备 30的类型对应的数据中转站 102, 然后由该数据中转站 102进行被远程设备 20和 远程设备 30之间的数据转发。 例如, 当前有三个 PC通过一个数据中转站 102来远程被远程设备 20, 此时, 如 果一个移动终端请求远程该被远程设备 20时,可以为该移动终端分配另一个数据中转 站 102,通过采用与远程设备 30类型对应的中转站,可以实现不同类型的远程设备 30 访问被远程设备 30。 在实施时,还可以根据为同一类型的远程设备 30设置多个数据中转站 102,例如, 服务器 10可以根据实际情况确定数据中转站 102的数目, 此时, 在选择数据中转站 102 时可以更具根据数据中转站的负载情况为已接入的同类型的远程设备分配一个中 转站。 优选地, 为了维护方便, 服务器 10可以对一个或多个远程控制组进行维护(在实 施时,对进行维护和管理的工作可以通过服务器 10中设置的服务中心来进行),其中, 远程控制组中记录的信息包括: 被远程设备 20的信息、 对该被远程设备 20进行控制 的一个或多个远程设备 30的信息以及与一个或多个远程设备 30类型对应的数据中转 站 102的信息。 优选地, 图 1所示的架构中,服务器 10可以对被远程设备 20和远程设备 30之间 交互的数据进行保存, 便于问题的查找。例如, 可以通过对来自被远程设备 20的桌面 信息进行录制, 并接收到回放请求之后, 对录制的桌面信息进行回放来查找问题。 优选地, 由于在远程设备 20和被远程设备 30之间设置了服务器 10, 那么, 在服 务器 10接收来自被远程设备 20的桌面信息之前, 可以由服务器 10对被远程设备 20 和远程设备 30进行认证, 这样可以保证远程控制的安全性。
在本实施例中, 还提供了一种服务器 10, 图 3是本发明实施例的服务器的结构框 图, 下面对该服务器 10涉及到的模块进行说明, 服务器 10包括: 第一数据转发模块 1022和第二数据转发模块 1024, 下面结合附图对该服务器进行说明。 第一数据转发模块 1022, 设置为接收来自被远程设备的桌面信息, 并将桌面信息 发送给远程设备; 第二数据转发模块 1024, 设置为接收来自远程设备的对被远程设备 进行的操作信息, 并将操作信息发送给被远程设备。 图 4是根据本发明实施例的服务器的优选结构框图一, 如图 4所示, 服务器 10 还包括: 一个或多个数据中转站 102和选择模块 104, 其中, 选择模块 104, 设置为选 择与远程设备的类型对应的数据中转站, 选择出的数据中转站 102包括第一数据转发 模块 1022和第二数据转发模块 1024。 图 5是根据本发明实施例的服务器的优选结构框图二, 如图 5所示, 服务器 10 还包括数据备份模块 106, 该模块设置为对来被远程设备 20和远程设备 30之间转发 的数据进行保存。 下面结合优选实施例进行说明 本优选实施例可以解决现有技术中的远程桌面过程存在的不同程度的缺陷,例如, 不能进行有效管理与监控、 不能同时支持多个不同类型的终端同时远程一台主机。 在 本优选实施例中,提供一种安全的、可管理与监控的以及可事后追溯的远程桌面技术, 以至少解决上述问题之一。 在本优选实施例中, 该远程桌面技术由用户端、 服务中心系统 (即服务器 10)和 支持端三部分构成, 其中, 服务中心系统包括服务中心和数据中转站。 服务中心系统 和用户端、支持端不一定处在同一个网络中, 在实际应用中, 服务中心系统和用户端、 支持端之间的所有数据传输均可以加密。 下面对三个部分分别进行说明。 用户端,用户端安装到被远程设备(在本优选实施例中也称为被远程主机) 20中, 用于执行的功能包括: 1、 登陆服务中心; 2、 负责获取被远程主机的桌面并将其编码 压缩后传输到数据中转站; 3、 决定是否接收某个远程主机 (即远程设备 30 ) 对本机 的操作; 4、在接收某个远程主机对本机的操作的前提下, 接收数据中转站发来的键盘 和鼠标消息并将该消息转换成对本机的操作。 支持端, 支持端安装到远程设备 (在本优选实施例中也称为远程主机) 30中, 用 于执行的功能包括: 1、 获取本机的屏幕、 CPU和内存等信息并在登陆时发送到服务
中心; 2、 登陆服务中心; 3、 负责从数据中转站接收被远程主机的桌面; 4、 向被远程 主机发起桌面操作请求; 5、在对被远程主机的操作过程中需要将本地操作发送到被远 程主机。 服务中心系统, 服务中心系统包括服务中心和数据中转站, 该服务中心用于执行 的功能包括: 1、 用户端和支持端的身份验证、 类型识别; 2、 各远程桌面过程的组管 理; 3、 根据支持端的类型分配不同的数据中转站; 4、 数据中转站的管理。 数据中转站, 数据中转站 102执行的功能包括: 1、接收和解码被远程主机的桌面 数据, 并根据支持端的类型进行重新编码、 压缩、 加密和转发; 2、 对接收的远程桌面 数据进行备份和本地回放; 3、 可以随时监控对任何一路远程数据的转发; 4、 统计转 发信息并定时向服务中心汇报转发状态。 在本优选实施例中, 还提供了一种可管理与监控的远程桌面方法, 图 6是本发明 优选实施例的可管理与监控的远程桌面方法的流程图, 如图 6所示, 该方法包括如下 步骤: 步骤 S602, 用户端登陆服务中心并提供一个便于识别的远程主机名; 步骤 S604, 服务中心为该用户分配数据中转站等资源, 并将该远程主机名加入到
"远程主机列表"中, 以便管理; 步骤 S606, 支持端登陆服务中心, 在登陆成功后从服务中心提供的"远程主机列 表"中选择要远程的主机名; 步骤 S608, 服务中心可以根据支持端的类型分配相应的数据中转站, 例如, 为 PC类型的支持端分配一个数据中转站,为手机等移动终端类型的支持端另外分配一个 数据中转站; 步骤 S610, 数据中转站根据服务中心分配的中转任务, 完成用户端和支持端之间 的数据中转, 同时备份所有接收到的数据; 步骤 S612, 支持端通过服务中心系统发送远程控制请求, 在用户端同意之后即可 进行远程桌面操作, 在同一时间只能有一个支持端进行远程桌面操作。 通过本实施例, 可以保证用户端与支持端的所有数据均通过服务中心系统的转发 和监控, 并在一定程度上保障了远程桌面过程中的安全性和可管理性; 另外, 在本实
施例中采用了分模块设计, 可以同时支持多个不同类型的计算机或者手机、 PDA等移 动终端同时远程一个位于异地的主机, 有效地提高了可扩展性。 图 7是根据本发明优选实施例的远程桌面技术的网络结构框图, 下面结合图 7进 行说明。 如图 7所示, 用户端、 支持端、 服务中心和数据中转站之间是相互独立的。 其中, 用户端、支持端和数据中转站都接受服务中心的管理和控制(如图 7中双向箭头所示), 用户端发送给支持端的远程信息也都将通过数据中转站的转发和监控 (如图 7中虚线 箭头所示), 另外, 在同一时间内支持一个支持端对用户端进行操作(如图 7中双点虚 线箭头所示)。 在本优选实施例中, 对不同类型终端的支持是通过为新类型终端增加相应的数据 中转站来实现的, 新类型终端的加入不会对原有远程状态造成影响。 图 8是根据本发 明实施例的连接不同终端时远程桌面技术的网络结构框图, 如图 8所示, 原有的远程 状态中支持端只有 PC支持端一种类型和一个数据中转站 1。 当有手机和 PDA等新类 型的小屏幕终端通过支持端加入时, 服务中心将根据该新类型的特点为其分配专门的 数据中转站 2, 数据中转站 2将从数据中转站 1中接收数据, 并将用户端的桌面重新 解码并编码为适合新类型的小屏幕数据, 因此, 新类型的支持端加入对用户端和原来 的支持端不会造成任何影响。 在本优选实施例中, 用户端主要由登陆模块、 桌面录制和编码模块、 网络传输模 块以及虚拟键盘和鼠标模块四部分构成。 下面对各个模块进行说明。 登陆模块, 主要向服务站中心注册本机信息, 需要向服务中心提供的信息主要包 括本机 IP、 各端口号、 便于识别的主机名 (用于支持端远程时进行选择)。 桌面录制和编码模块, 将对桌面进行录制和编码。 由于桌面的变化频率大大小于 视频, 在本优选实施例中, 优选 TSCC编码作为桌面编码方式, 但是不限于此。 网络传输模块, 主要将录制的桌面数据加密并传输到数据中转站, 同时保障数据 传输中的 QOS。 虚拟键盘和鼠标模块, 在用户端 (即被远程设备) 同意某个支持端进行远程桌面 操作之后才启用的功能, 该模块将接收该用户端的远程键盘和鼠标操作并转换为对本 机的操作, 它的完成过程需要用户端和支持端合作。 图 9是根据本发明优选实施例的 鼠标位置转换的示意图, 如图 9所示, 被远程桌面的长和宽分别为 A和 B, 坐标原点
为 02, 在远程桌面上显示的长和宽为 a和 b, 坐标原点为 01, 当支持端鼠标的点击 位置为 Pl(x,y)时,支持端将该坐标转换为相对 01的相对坐标 (x/a,y/b)并发送给用户端, 用户端接收到相对坐标 (x/a,y/b)后转换为在本机桌面的绝对鼠标位置 (Ax/a,By/b)。 在本优选实施例中, 支持端由登陆模块, 网络传输模块, 解码与显示模块以及虚 拟键盘和鼠标模块四部分构成。 下面对各个模块进行说明。 登陆模块, 主要向服务中心发送本机信息(例如本机 IP、终端类型、各端口号等) 和用户名、 密码等身份信息。 网络传输模块, 完成加解密和数据传输功能, 它主要负责接收远程桌面信息和发 送本机的操作命令, 并负责保证传输过程中的 QOS。 解码和显示模块, 主要负责将接收到的远程桌面流进行解码和显示。 虚拟键盘和鼠标模块, 主要在支持端发送远程桌面操作请求并获得用户端同意之 后才启用的功能, 它主要负责将本机的键盘和鼠标命令转换后发送给数据中转站。 在本优选实施例中, 服务中心主要由身份验证、 组管理、 数据中转站管理三部分 构成。 下面对各个模块进行说明。 身份验证模块, 主要对登陆的用户端和支持端进行身份验证。 组管理模块, 主要是对各远程过程进行管理。 需要说明的是, 一个组包含一个用 户端, 多个支持端和数据中转站, 组名为用户端创建的主机名, 其中, 组的属性中包 括用户端相关信息(例如, IP、各端口号、用户名和密码等)、支持端相关信息(例如, 终端类型、 IP、 各端口号, 用户名和密码, 是否进行远程操作等) 以及数据中转站的 相关信息(例如, 数据中转站的转码类型、 负载状态等), 服务中心对远程过程的管理 主要通过组来完成。 数据中转站的管理, 主要根据支持端类型和负载状态搭建数据中转站树, 为减轻 数据中转站的转码压力一个数据中转站只完成一种类型的转码, 也即同一个数据中转 站只支持同一种类型的支持端, 当有新类型支持端加入时需要为其另外分配数据中转 站, 其中, 服务中心对数据中转站进行负载均衡以保证传输质量, 当一个数据中转站 的转发的数据过多时 (如图 8中的数据中转站 1 ) 需要对其进行负载均衡, 服务中心 可以再分配一个数据中转站 2,将数据中转站 1的部分负载分配给数据中转站 2, 从而 实现负载均衡, 如图 10所示为进行负载均衡后的转发架构图。
在本优选实施例中, 数据中转站主要由转码模块、 数据转发模块、 数据备份和回 放模块、 负载监控模块四部分构成。 下面对各个模块进行说明。 转码模块, 首先按照服务中心的要求将用户端传来的远程桌面数据转码成适合支 持端显示的类型, 此处的转码主要是为了适应不同屏幕大小的支持端 (例如, 将 PC 的桌面直接发送给到手机上时可能导致无法分辨原来桌面上的内容, 因此, 需要采用 缩放算法将 PC机的桌面缩放后才能在手机上清晰显示)。 数据转发模块, 主要根据服务中心提供的信息从用户端的指定端口接收数据或者 向用户端的指定端口发送数据, 同时数据转发模块还完成对接收数据的解密和对发送 数据的加密功能。 数据备份和回放模块, 主要完成将接收的远程桌面数据压缩后存放到指定位置, 同时将某路接收解码后的数据进行本地回放以便接受实时监控。 需要说明的是, 数据 备份和回放模块的启动与否是可选的, 即可以根据实际情况决定是否对某路接收到的 桌面数据进行备份和回放, 但是数据中转站同时只能回放一个组的数据。 负载监控模块, 主要对本机的网络流量、 CPU和内存利用率进行实时监控, 并定 时向服务中心上报本机的负载状态以便服务中心进行负载均衡。 通过上述实施例, 为现有的远程桌面技术中存在的安全隐患或技术上的限制的问 题的解决提供了可能, 进而更有利于远程桌面技术的应用。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所 组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而可以将 它们存储在存储装置中由计算装置来执行,或者将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限 制于任何特定的硬件和软件结合。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
