Definitions
- the present invention relates to the field of communications, and in particular, to a cloud terminal upgrade method, system, network management server, and proxy server.
- Cloud terminal products can be used not only in the desktop cloud, but also in the basic office of the communications industry, government and enterprise industries, and financial industry. Cloud terminal systems are diverse, and version changes are fast. Enterprises need to centrally upgrade and maintain large numbers of cloud terminals. How to make large-scale cloud terminal systems perform remote and rapid upgrades will be a primary problem to be solved. At present, there are two main types of upgrade methods for similar products of cloud terminals:
- the terminal uses the hypertext transfer protocol (http) to download the image upgrade or mount to the NFS server upgrade.
- http hypertext transfer protocol
- each terminal establishes a connection, which requires high bandwidth for the server. If too many terminals are upgraded at the same time, the redundant data traffic on the network will be greatly increased, and the upgrade speed will be reduced. In this way, thousands of cloud terminals can be upgraded for 2-3 days. Obviously, it is not advisable to perform image upgrades on large-scale terminals.
- the second method is to adopt the multicast upgrade mode: the network management server sets the proxy server and multicast upgrade information, and the terminal downloads the image file from the proxy server to complete the upgrade.
- the proxy server will only send one data, and its destination address is the multicast group address. All terminals in the multicast group can receive the same data copy.
- Multicast upgrade effectively solves the problem of centralized upgrade of multiple cloud terminals, and achieves efficient data transmission from point to point in the network, which can effectively save network bandwidth and reduce the load on servers and networks.
- the experimental data shows that under the same network bandwidth resource, the 10 cloud terminal multicast upgrade mode saves twice the time than the NFS upgrade (unicast mode). If the number of terminals is more, the time saved is more.
- the main technical problem to be solved by the present invention is to provide a cloud terminal upgrade method, a system, a network management server, and a proxy server, and to solve the problem that the existing multicast upgrade mode needs to change the original routing configuration information when the cloud terminal is upgraded across the network segment, resulting in security.

Description
本发明涉及通信领域，具体涉及一种云终端升级方法、系统、网管服务器及代理服务器。
随着云计算及相关技术的快速发展，满足不同应用场景的云终端产品相继出现。云终端产品不仅可以配套桌面云使用，也可单独使用，可广泛应用到通讯行业、政企行业、金融行业等领域的基本办公。云终端系统多种多样，版本变更速度快，企业需要对大批量的云终端进行集中升级维护，如何使得大规模的云终端系统系进行远程快速升级，将是一个首要需要解决的问题。目前，针对云终端类似产品采用的升级方式主要有两类：
一类是采用服务器对云终端单播通信方式：终端使用超文本传输协议(http)下载镜像升级或者挂载到NFS服务器升级。升级时，每个终端都会建立一个连接，对服务器的带宽要求很高。若同时升级的终端太多，将大大增加网络上的冗余数据流量，降低升级的速度。使用这样的方式对上千规模的云终端进行升级，时间大概要2-3天。很明显的，对大规模终端进行镜像升级，这种方法不可取。
第二类方法就是采用组播升级的方式：网管设置代理服务器与组播升级信息，终端到代理服务器下载镜像文件完成升级。代理服务器只会发一份数据，其目的地址为组播组地址，组播组中的所有终端都可收到同样的数据拷贝。组播升级有效地解决了多个云终端集中升级的问题，实现了网络中点到多点的高效数据传送，能够有效地节约网络带宽、减轻服务器及网络的负载。实验数据显示，在相同网络带宽资源下，10台云终端组播升级方式比NFS升级(单播方式)节约2倍的时间，若终端数目越多，节约的时间便更多。
组播升级的效果是毋庸置疑的，但在大规模云终端分布在不同网段的应用场景中，有个缺点：当代理服务器与被升级终端不在同一网段时，需要在路由器上设置组播包路由信息，组播包才能到达目标终端。在一个大型企业中，可能有成千上万台终端分布在很多不同的网段，为了升级管理这些终端，改变企业原本路由的配置信息(有些路由甚至是企业的核心路由)是个很糟糕的做法。因为路由配置改变会给企业带来很多安全性的问题和不必要的麻烦。

本实施例中，为了进一步所选择的代理服务器3可可用性，选择模块22还包括启动子模块，设置为在匹配子模块将在云终端列表中的云终端作为代理服务器3之前，启动该云终端的组播服务，如启动成功，将其作为代理服务器3；否则，通知选择子模块在该组内选择下一个云终端进行匹配。
请参见图4所示，本实施例中的网管服务器2还包括配置模块24，设置为从各组的云终端中分别选择一个云终端作为各组的代理服务器3后，向代理服务器3下发组播升级配置参数，具体可通过TR069模块发送给代理服务器3；该组播升级配置参数包括组播地址(例如组播端口)、传输速率(例如支持的最大传输速率)以及传输方式(例如单工还是双工方式)中的至少一种。代理服务器3接收到该组播升级配置参数后，进行相应的组播配置。
请参见图5所示，本实施例中的代理服务器3包括接信息收模块31和信息发送模块32；
信息接收模块31设置为接收网管服务器2以单播方式发送的待升级文件；
信息发送模块32设置为将接收到的待升级文件发给代理服务器3所在组内的其他云终端进行升级。本实施例中的信息发送模块32为组播发送模块，通过组播的方式将所待升级文件发给其所在组内的其他云终端进行升级，以提升升级效率和资源利用率。
请参见图6所示，本实施例中的代理服务器3还包括升级模块33，设置为在代理服务器3所在组内的其他云终端根据待升级文件完成升级后，根据该待升级文件完成
代理服务器3自身的升级。当然，在一些具体应用场景中，代理服务器3也可在该组内第一个完成升级。
实施例二：
本实施例提供了云终端升级方法，请参见图7所示，包括：
步骤701：网管服务器将不同网段的云终端按网段进行分组，一个组包含一个网段中的云终端；
步骤702：网管服务器从各组的云终端中分别选择一个云终端作为各组的代理服务器；
步骤703：网管服务器将待升级文件以单播方式发给各代理服务器；例如通过NFS方式将待升级文件上传至各代理服务器；
步骤704：代理服务器将接收到的待升级文件发给其所在组内的其他云终端进行升级。
上述步骤702中，网管服务器从各组的云终端中分别选择一个云终端作为各组的代理服务器包括：
网管服务器从组内的云终端中选择一个云终端，并将其与预设的具有组播功能的云终端列表进行匹配，如该云终端在云终端列表中，表明其具备组播功能，则将其作为代理服务器；否则，在该组内选择下一个云终端进行匹配，直到匹配成功。
本实施例中，为了保证选择的代理服务器的可靠性，在网管服务器判定当前选择的云终端在所述云终端列表中，将其作为代理服务器之前，还包括：
启动该云终端的组播服务，如启动成功，才将其作为代理服务器；否则，在该组内选择下一个云终端进行匹配。
在上述步骤702之后，网管服务器从各组的云终端中分别选择一个云终端作为各组的代理服务器后，还包括向代理服务器下发组播升级配置参数，具体可通过TR069模块发送给代理服务器；该组播升级配置参数包括组播地址(例如组播端口)、传输速率(例如支持的最大传输速率)以及传输方式(例如单工还是双工方式)中的至少一种。代理服务器接收到该组播升级配置参数后，进行相应的组播配置。
上述步骤704中，代理服务器通过组播的方式将待升级文件发给其所在组内的其他云终端进行升级；以提升升级效率和资源利用率；当然，在组内云终端个数较少的情况下，可以采用单播的放置将待升级文件发给组内自他终端。本实施例中组播可以采用轮询组播的方式。
在上述步骤704之后，也即代理服务器在其组内的其他云终端根据待升级文件完成升级后，还包括根据待升级文件完成自身的升级步骤。
本实施例中，云终端从代理服务器获取待升级文件之前，还包括从代理服务器获取待升级文件的分区信息(包括待升级文件所需的空间大小等)，并与自身的分区信息(例如自身剩余空间的大小等)进行匹配，如匹配成功，才加入组播组接收代理服务器通过组播方式发送的待升级文件，否则，等待下一轮匹配成功后再加入组播组。上述过程具体请参见图8所示，包括：
步骤801：网管服务器将跨网段的各云终端按网段分组，每个组内的云终端都在同一网段内；
步骤802：网管服务器从每个组内选择一个云终端作为该组的代理服务器；选择时刻根据其本地存储的具备组播功能的终端列表进行匹配选择；
步骤803：网管服务器启动该代理服务器的组播服务功能；
步骤804：判断启动是否成功，如是，转至步骤805；否则，转至步骤802；
步骤805：为该代理服务器配置组播升级配置参数，使用NFS方式将待升级文件上传至各代理服务器；
步骤806：网管服务器启动各代理服务器开始组播升级；
步骤807：各组内的其他云终端从指定代理服务器获取到待升级文件完成升级；具体包括：组内待升级的其他云终端到指定的代理服务器获取待升级文件(可以是镜像文件)的分区信息，并与自身的分区信息进行匹配，如成功，云终端重启进入升级的系统，加入到组播组；
代理服务器将待升级文件发送给组播组内的云终端，数据发送完毕后组播组内的云终端重启进入正常的系统完成升级；
代理服务器程序重启，等待上一轮未加入的待升级的云终端加入，再次发送组播数据；
该组内的所有云终端完成升级；
步骤808：代理服务器在其所在组内的其他云终端升级完毕后，根据接收到的待升级文件完成自身的升级。
本实施例中，网管服务器可以逐个组的启动各组的组播升级，也可以同时启动多个组的组播升级。
应当理解的是，本发明提供的方案并不局限于跨网段云终端的升级，对于只有一个网段的组网中的云终端也适用。
可见，本发明提供的云终端升级的方法，网管服务器在不同网段内设置云终端作为代理服务器，通过NFS方式上传终端镜像文件(也即待升级文件)至该网段的代理服务器，通过TR069协议设置终端组播升级配置参数。该网段的其他云终端通过代理服务器完成组播升级。这种方法有效的规避了跨网段组播升级中路由设置带来的安全问题，提高了升级云终端效率，节省了网络带宽。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
基于本发明的实施例提供的上述技术方案，通过网管服务器以网段为单位对各云终端进行分组，然后网管服务器从各组的云终端中分别选择一个云终端作为各组的代理服务器，进而先通过单播的方式将待升级文件发送各代理服务器，由于通过单播的方式发送，因此并不需要改变原本路由配置信息，本发明的实施例在升级时并不需要改变原本路由配置信息，可以提升升级过程中的安全性，进而提升用户体验的满意度。
