Description

远程终端运行环境的加载方法及系统
技术领域
本发明涉及云计算领域， 特别是涉及一种云计算模式下远程终端运行环境 的加载方法及系统。 背景技术
随着计算机技术和网络技术的飞速发展与应用， 计算机的硬件和软件的更 新换代日益频繁， 为了能够使现有的设备发挥最大作用， 以便减低成本， 并且 能够便于管理和维护， 无盘网络技术得以发展。
无盘工作站是计算机网络的一种特殊应用。 总的来说， 无盘工作站是由网 卡的启动芯片 （Boot ROM) 以不同的形式向服务器发出启动请求， 服务器收到 后， 根据启动机制， 向工作站发送启动数据， 工作站下载完启动数据后， 系统 控制权由 Boot ROM转到内存中的某些特定区域， 并引导操作系统。
目前国内最常用的无盘工作站的组建方式有以下两种：
一种是远程启动服务（RPL， Remote Initial Program Load)技术。 RPL技 术用于在 Windows NT 下实现引导 Windows95。 由于 Windows NT 具有远程启动 服务， 因此可以使用服务器硬盘上的软件来代替工作站硬盘引导一台网络上的 工作站。 工作站的网卡上必须装有一个 RPLR0M 芯片， 每一种 RPL R0M 芯片都 是为一类特定的网络适配卡而制作的， 它们之间不能互换。 带有 RPL的网络适 配卡发出引导记录请求的广播 （broadcasts ) , 服务器自动的建立一个连接来 响应它， 并加载相关启动文件到工作站的内存中。
另一禾中是远程预启动执行环境 (PXE, Preboot Execution Environment) 技术。是由 Intel设计的协议，它可以使计算机通过网络启动。协议分为 Cl ient 和 Server两端， PXE cl ient在网卡的 ROM中， 当计算机引导时， BIOS把 PXE Cl ient调入内存执行， 并显示出命令菜单， 经用户选择后， PXE Cl ient 将放 置在远程的操作系统通过网络下载到本地运行， 是 RPL的升级产品。 RPL技术和 PXE技术的不同之处在于： RPL是静态路由， PXE是动态路由。 RPL是根据网卡上的 ID 号加上其它的记录组成的一个帧向服务器发出请求， 而服务器那里早已经有了这个 ID数据， 匹配成功则进行远程启动； PXE则是根 据服务器端收到的工作站 MAC地址， 使用 DHCP服务给这个 MAC地址指定一个 IP地址， 每次重启动可能同一台工作站与上次启动有不同的 IP, 即动态分配 地址。利用 PXE 技术，可实现操作系统、应用软件的安装，并能实现远程启动， 它还可以进行远程紧急引导， 如果客户机在系统启动时失败， 可以在服务器端 下载系统影像文件， 帮助诊断和恢复客户机的故障。 因此目前 PXE技术的应用 比 RPL技术要广泛。
但是， 无盘工作站技术主要适用于局域网中， 并不适用于通过互联网来进 行远程终端与服务器的交互， 尤其不适用于在三网融合模式、 或者云计算模式 下加载远程终端运行环境。
目前， 在互联网技术中， 出现了一种客户端通过与服务器交互来获得操作 系统的概念， 叫做透明计算。 公开号为 CN1670698A的中国专利申请公开了如 下技术内容： 透明计算系统是一种由终端设备、 服务器和连接终端设备与服务 器的网络组成的一种用户无需感知计算机操作系统、 中间件、 应用程序和通信 网络的具体所在，只需根据自己的需求，通过网络从所使用的各种终端设备（包 括固定、 移动、 以及家庭中的各类终端设备） 中选择并使用相应服务（例如计 算、 电话、 电视、 上网和娱乐等） 的计算模式。
理想的透明计算包括三个部分， 一个是整合了当前 PC、 PDA, 智能手机、 数字家电等轻权设备的透明客户端； 一个是整合当前各种网络设备与互联设备 的透明网络； 最后一个是整合了大量计算能力较强或者很强的普通个人微机、 服务器、 大型机等的透明服务器。 从总体上看， 透明计算构建在一个更加广泛 的物理设备之上， 运行环境更加灵活。 透明客户机可以是没有安装任何软件的 裸机， 也可以是装有部分核心软件平台的轻巧性终端。
透明服务器是带有外部存储器的计算装置， 例如 PC机、 PC级服务器、 高 档服务器、 小型机等。 透明服务器存储用户需要的各种软件和信息资源， 同时 还要完成透明计算系统的管理与协调， 例如各种不同操作系统核心代码的调 度、 分配与传输， 各种不同软件服务往透明客户机上的调度、 分配与传输等过 程的管理。透明客户端与服务器之间的连接由透明网络完成， 透明网络是指一 种在目前常用的局域网或广域网基础上增加了特定通信协议的网络系统， 这种 网络系统可以基于以太网、 CATV、 802. 11、 IEEE 1394等传输系统， 甚至是基 于 3G、 4G的通信网络。
但是， 发明人在实现本发明的过程中， 发现现有技术的缺陷在于： 透明计 算需要客户端用户手动选择操作系统， 并向服务器发送下载所选的操作系统镜 像的请求， 用户操作复杂且容易出错； 并且， 服务器根据客户端用户的选择发 送相应的操作系统或操作系统镜像， 需要在客户端启动操作系统， 设备加载服 务的效率低， 速度慢。 发明内容
本发明的目的在于提供一种远程终端运行环境的加载方法及系统，在加载 运行环境的过程中不需人工干预， 并且设备加载服务的效率高， 启动速度快。
为实现上述目的， 本发明实施例提供一种远程终端运行环境的加载方法， 应用于云计算模式下的远程终端， 所述方法包括：
远程终端加电自检后， 进行网络初始化连接至服务器， 并向所述服务器发 送包含设备识别信息的下载请求；
接收所述服务器根据所述下载请求发送的所述远程终端对应的内存镜像； 根据所述内存镜像还原所述远程远程终端的内存信息， 使所述远程终端完 成运行环境的加载。

服务器接收远程终端发送的包含设备识别信息的下载请求； 根据所述设备识别信息选择对应于所述远程终端的内存镜像； 将所述远程终端对应的内存镜像发送至所述远程终端， 以使所述远程终端 完成运行环境的加载。

为使本发明的目的、 技术方案和优点更加清楚明白， 下面结合实施方式和 附图， 对本发明做进一歩详细说明。 在此， 本发明的示意性实施方式及其说明 用于解释本发明， 但并不作为对本发明的限定。
本发明实施例提供一种远程终端运行环境的加载方法和系统。 以下参考附 图对本发明进行详细说明。
实施例 1
本发明实施例提供一种远程终端运行环境的加载方法， 应用于云计算模式 下的远程终端。
如图 1所示， 所述方法包括：
歩骤 101， 远程终端加电自检后， 进行网络初始化连接至服务器， 并向服 务器发送包含设备识别信息的下载请求；
歩骤 102， 远程终端接收服务器根据下载请求发送的该远程终端对应的内 存镜像；
歩骤 103， 远程终端根据获得的内存镜像还原内存信息， 使该远程终端完 成运行环境的加载。
在本实施例中，远程终端可为网络电视机、手机、个人计算机（PC, Personal
Computer ), 个人数字助理 （PDA, Personal Digital Assistant ), 数字家电 等等， 但不限于此， 可根据实际情况确定具体的设备。
在本实施例中， 远程终端与服务器的通信可建立在 TCP/IP协议上， 在内 存镜像调入内存之前， IP网络是连通的， 即需要独立于操作系统的 IP协议栈 或者其他网络通讯模块完成网络连接和通讯功能。
在歩骤 101实施时， 远程终端可加电自检， 初始化网络模块， 连接到服务 器， 该网络模块可以由 BIOS或者网络芯片实现。
在歩骤 101实施时， 远程终端在加电自检后， 还可进行自我检测， 获取该 远程终端的设备识别信息。 但不限于此， 还可在出厂时预存该远程终端的设备 识别信息， 可根据实际情况确定具体的实施方式。
在歩骤 101 实施时， 设备识别信息可包括远程终端的类型、 和 /或远程终 端的型号。 例如， 设备识别信息可为两个字符串： "3 " " 1. 2 "， 其中， "3 "表 示远程终端为网络电视， " 1. 2 "表示该网络电视的型号为 1. 2。 以上仅为示意 性说明， 但不限于此， 可根据实际情况确定具体的实施方式。
在歩骤 102实施时，服务器可根据设备识别信息选择对应于远程终端的内 存镜像， 该内存镜像可采用文件的记录形式。
内存镜像与操作系统的镜像区别在于： 操作系统镜像是一种静态的存储的 形式； 而内存镜像是操作系统在内存中的快照， 是一种动态的概念。 在一个特 定的瞬间， 内存镜像反映了一个特定时间内存的状态。
远程终端可通过独立的下载模块和服务器进行有效的交互， 完成指定内存 镜像的下载， 该下载模块独立于操作系统， 即不是操作系统的一部分， 可以是 固件上的功能， 可以由 BIOS或者芯片实现。
在歩骤 103实施时， 远程终端可根据获得的内存镜像还原内存信息， 将控 制权交给操作系统， 使该远程终端完成运行环境的加载。 可通过 BIOS或者芯 片实现上述功能。
在本实施例中， 对于远程终端， 例如一款特定型号的电视机或者手机， 它 的硬件或者功能在不发生变化的情况下， 启动的基本服务和软件将不发生变 化， 换句话说， 内存和进程的分配可以不发生变化。
在启动远程终端时， 可从服务器调入该远程终端的内存镜像， 还原设备内 存中操作系统 （包括内存分配、 进程 /线程、 设备等， 但不限于此） 的信息， 然后交给操作系统完成启动过程。
例如， 假设设备出厂状态需要运行 1-10号进程。 生产厂家可在远程终端 出厂前， 设定操作系统运行 1-10号进程。 首先， 系统引导 0号进程， 0号进程 从 1号开始逐个引导， 直到 10号进程完成； 此刻内存的内存快照是操作系统 完成初始化和 1-10号进程安装完成的状态； 然后， 获取该时刻内存快照， 并 在服务器端保存内存镜像； 出厂之后， 在终端用户开启远程终端后， 从服务器 获取内存镜像， 直接恢复到出厂之前内存的状态。
这样， 可将内存还原到某一时刻的状态， 省掉了 0号进程逐个初始化系统 进程、 以及重新分配内存和地址空间的过程。 内存还原以后， 系统回到了系统 引导完成以后的一个状态。
在现有技术中， 远程终端通过局域网或者互联网下载操作系统或者操作系 统镜像后， 还需要启动操作系统， 初始化内存和进程； 加载服务、 初始化内存 和启动进程是整个操作系统启动过程中最消耗时间的。 而在本发明中， 该过程 免除了内存初始化、 进程初始化的过程， 很大程度上提高了系统执行的效率。 特别是针对大批量生产的相同型号设备， 比如电视机嵌入式操作系统， 可以提 高系统的执行效率， 减少系统维护成本。
由上述实施例可知， 通过设备识别信息选择相应的内存镜像， 可不需要人 工干预， 可靠性好且有较好的用户体验； 并且， 服务器根据请求向远程终端传 送内存镜像， 不需要在远程终端启动操作系统， 设备加载服务的效率高， 启动 速度快。
实施例 2
本发明实施例提供一种远程终端运行环境的加载方法， 应用于云计算模式 下的服务器。 如图 2所示， 所述方法包括：
歩骤 201， 服务器接收远程终端发送的包含设备识别信息的下载请求； 歩骤 202， 服务器根据设备识别信息选择对应于远程终端的内存镜像； 歩骤 203， 服务器将远程终端对应的内存镜像发送至远程终端， 以使远程 终端完成运行环境的加载。
在歩骤 201 实施时， 设备识别信息可包括远程终端的类型和 /或远程终端 的型号。
在歩骤 202实施时， 服务器可根据远程终端的类型和 /或远程终端的型号 选择对应的内存镜像。
在现有技术中， 用户需要首先获得服务器中操作系统的列表， 根据操作系 统的列表手动选择远程终端的操作系统， 因此， 需要人工干预， 如果不熟悉硬 件设备的类型和型号很容易选择错误的操作系统， 可靠性低且用户体验度差。 而在本发明中，远程终端自动将设备识别信息发送给服务器，不需要人工干预， 效率高且有较好的用户体验。
由上述实施例可知， 通过设备识别信息选择相应的内存镜像， 可不需要人 工干预， 效率高且有较好的用户体验； 并且， 服务器根据请求向远程终端传送 内存镜像， 不需要在远程终端启动操作系统， 设备加载服务的效率高， 启动速 度快。
