本发明提供一种文件分发系统，如图1所示，为本发明实施例提供的一种文件分发系统的结构示意图，本实施例提供的文件分发系统包括：主控节点100和多个文件分发服务器200。
其中，主控节点100，与基站300和多个文件分发服务器200进行通信，该主控节点100设置为：接收基站300发送的下载请求，并响应该下载请求为基站300分配文件分发服务器200，该主控节点100还设置为：对多个文件分发服务器200进行集中控制和管理；
多个文件分发服务器200，分别与主控节点100进行通信，每个文件分发服务器200设置为：向主控节点100分配到本文件分发服务器200的基站300提供下载文件。
需要说明的是，图1所示的文件分发系统仅是一种示意性描述，在实际情况中，文件分发系统中可以有一个主控节点，也可以有多个主控节点，即，可以通过一个主控节点对多个文件分发服务器进行集中控制和管理，也可以通过两个或更多主控节点对多个文件分发服务器进行集中控制和管理。另外，在实际情况下，基站的数量也是不一个，通常具有多个。
可选地，在本发明实施例中，上述的多个文件分发服务器中的每个文件分发服务器可以单独放在一个地方，每个文件分发服务器中都存储有一份完整的下载文件的副本，位于不同地点的任意两个文件分发服务器之间可以通过网络互相连接，共同组成一个完整的、全局的逻辑上集中、物理上分布的系统。
本发明实施例提供的文件分发系统，包括主控节点和多个文件分发服务器，通过在该文件分发系统中加入的主控节点对多个文件分发服务器进行集中控制和管理，并在该主控节点接收到基站发送载请求后，为该基站分配文件分发服务器，从而提高了文件分发系统的扩展方式的便捷性，即可以通过简单的添加硬件设备来实现文件分发服务器的扩容；本发明实施例解决了相关技术中的文件分发系统由于扩容困难，而导致的文件分发系统难以满足海量文件分发的需求的技术问题，达到了有效满足海量文件分发的需求的技术效果。
可选地，在本发明实施例中，对上述多个文件分发服务器200中的每个文件分发服务器200中都可以配置有存储器，每个文件分发服务器200的存储器中存储有相同的下载文件的副本，即，每个文件分发服务器200中都可以存储有一份完整的下载文件的副本，这样，在主控节点100接收到基站300发送的下载更新请求后就可以按照需要随意分配一个文件分发服务器200为该基站提供下载文件。
本发明实施例中的上述主控节点100主要的两个作用，一个是为基站分配文件分发服务器，另一个是对多个文件分发服务器进行集中控制和管理。
基于上述主控节点100的第一个作用，本发明实施例还提供了一种文件分发系统的管理方法，如图2所示，为本发明实施例提供的一种文件分发系统的管理方法的流程图，本实施例提供的方法可以包括以下步骤，即步骤110～步骤120：
步骤110，接收基站发送的下载请求；
步骤120，响应该下载请求，为该基站分配文件分发服务器，所分配的文
件分发服务器用于提供下载文件。
可选地，在本发明实施例的步骤120中，可以采用负载均衡的方式为该基站分配文件分发服务器，即，如果主控节点接收到基站发送的下载请求，那么可以选择当前负荷比较低的文件分发服务器为该基站提供下载文件。
基于上述主控节点100的第二个作用，本发明实施例还提供了一种文件分发系统的管理方法，如图3所示，为本发明实施例提供的另一种文件分发系统的管理方法的流程图，本实施例提供的方法可以包括以下步骤，即步骤210～步骤220：
步骤210，接收文件分发服务器上传的信息；
步骤220，根据文件分发服务器上传的信息对该分发服务器进行集中控制和管理。
可选地，在本发明实施例的步骤220中，当该信息为注册消息时，可以将该文件分发服务器增加到文件分发服务器集群中，并将该文件分发服务器的状态设置为可用状态；即，可以将新的文件分发服务器增加到文件分发服务器集群中，从而在文件分发系统有扩容需求的时候，可以简单地在该文件分发系统中增加新的文件分发服务器，以满足海量文件分发的需求。
可选地，如图4所示，为本发明实施例提供的又一种文件分发系统的管理方法的流程图。在图3所示实施例的基础上，为了保证文件分发服务器上文件的完整性，且可以及时发现存在问题的文件分发服务器，本实施例提供中的步骤210可以包括如下步骤，即步骤211～步骤212：
步骤211，向文件分发服务器周期性地发送轮询请求消息；
步骤212，接收该文件分发服务器返回的轮询反馈消息；从而，可以根据接收到的轮询反馈消息可以对该文件分发服务器进行集中管理和控制。
可选地，在本发明实施例中，上述步骤220可以包括如下步骤，即步骤221～步骤222：
步骤221，根据轮询反馈消息确定文件分发服务器中存储的下载文件的副本是否丢失或损坏；
步骤222，当确定出所述文件分发服务器中存储的下载文件的副本已丢失
或损坏时，为文件分发服务器重新同步该下载文件的副本。
可选地，在本发明实施例的另一种应用场景中，步骤220的实现方式也可以为：在预定时间或者预定次数内未接收到文件分发服务器返回的轮询反馈消息时，将该文件分发服务器从文件分发服务器集群中移除。
根据上述实施例和可选实施方式提供的技术方案，可以根据轮询反馈消息确定文件分发服务器中存储的下载文件的副本是否丢失或损坏，也可以根据轮询反馈消息的接收情况，来确定文件分发服务器是否失效。
本发明实施例还提供了一种文件分发系统的管理装置，该装置用于实现上述实施例及可选实施方式，已经进行过说明的不再赘述。如以下所使用的术语“单元”或者“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。

其中，请求接收模块401，设置为：接收基站发送的下载请求；
分配模块402，设置为：响应于请求接收模块401接收的下载请求，为基站分配文件分发服务器，所分配的文件分发服务器用于提供下载文件。
可选地，在本发明的一个实施方式中，上述分配模块402，是设置为：采用负载均衡的方式为该基站分配该文件分发服务器。

可选地，在本实施例一个实施方式中，上述管理模块502还可以包括：
移除单元5024，设置为：在发送单元5011向文件分发服务器周期性地发送轮询请求消息之后，在预定时间或者预定次数内未接收到该文件分发服务器返回的轮询反馈消息时，将该文件分发服务器从文件分发服务器集群中移除。
上述图5到图7中的文件分发系统的管理装置可以设置于图1所示文件分发系统的主控节点100中，用于对文件分发集群进行集中控制和管理。
以下以一个应用实例对本发明实施例提供的文件分发系统、文件分发系统的管理方法和管理装置进行详细说明。
本应用实例中提供了一种文件分发系统、文件分发系统的管理方法和管理装置，通过将控制流和数据流分开，并提供弹性的、可扩充的文件分发服务器，使用多个文件分发服务器分担负荷，并且可根据需要较便捷的加入或移除文件分发服务器。
该文件分发系统可以包括一个管理(Manager)节点(对应于上述实施例中的主控节点)，多个的代理(Agent)服务器(对应于上述实施例中的文件分发服务器)。Manager节点对文件分发系统的管理方式主要可以包括：Agent服务器的加入、Agent服务器的移除、文件在Agent服务器之间的拷贝、Agent服务器上的下载连接数等。Manager节点可以周期性地向每个Agent服务器发送心跳信息，从而与每个Agent服务器实现通信。
每个Agent服务器可单独放在一个地方，每个Agent服务器中都有文件内容的一份份完整的拷贝副本，位于不同地点的多个Agent服务器可以通过网络互相连接，共同组成一个完整的、全局的逻辑上集中、物理上分布的系统。为了降低系统的瓶颈效应，保证所有Agent服务器与Manager节点之间的操作最小化，可以将数据流和控制流分开。
Manager节点会周期性地向Agent服务器发送信息以轮询每个Agent服务器的状况，可以包括Agent服务器所存放的文件信息，与之建立连接的基站信息，下载进度等。Manager节点上可以保存一份完整的文件列表，该文件列表可以包括：文件名、文件大小以及文件校验值，以及每个Agent服务器上存放的文件信息，其中，上述文件校验值例如为循环冗余校验(Cyclic Redundancy Check，简称为：CRC)或消息摘要算法第五版(Message Digest Algorithm MD5，简称为：MD5)等。在实际应用中，Manager节点可以完成以下几种对Agent服务器的集中控制和管理工作：
1)Agent服务器的加入
当一个Agent服务器加入时，该Agent服务器会向Manager节点发送消息进行注册，该消息的内容可以包括：硬件配置、Agent服务器上运行的软件版本等信息。Manager节点接收到Agent服务器的注册请求后，将该Agent服务器加入到分布式文件分发集群中；随后，通知新注册的Agent服务器从另一个拥有完整文件副本的Agent服务器上同步文件，为了防止同步文件的副本产生的开销太大，Manager节点会按照一定策略限制整个集群中和每个Agent服务器上同时进行同步的数量；在同步完成后，Manager节点会将新加入的Agent服务器的状态设置为可用状态。
2)Agent服务器的失效
当出现以下情况时，可以定义Agent服务器失效：Agent服务的软件关闭；Agent服务器一定时间或一定次数不回应Manager节点的轮询请求消息，当基站向Agent服务器请求下载而失败一定次数的情况下，或者其它Agent服务器主动上报的自身不可用等情况时，可以确定该Agent服务器失效。
在确定Agent服务器失效后，Manager节点会将该Agent服务器从分布式文件分发集群中移除，当有新的基站请求时，Manager节点将该基站请求分配给其它Agent服务器。对于移除前已确认完成文件下载或同步的对象，Manager节点为其重新分配Agent服务器，并通知该Agent服务器重新执行文件下载操作。
3)Agent服务器上的文件丢失或损坏
Agent服务器收到Manager节点的周期性轮询请求消息时，会向Manager节点上报该Agent服务器存储的文件信息，Manager节点对上报信息进行分析，如果发现文件丢失或损坏，Manager节点会重新向该Agent服务器发送文件同步指令。另外，当有基站向Agent服务器发起请求文件，或其它Agent服务器向该Agent服务器发起文件同步请求时，被请求文件版本的Agent服务器会对文件进行校验，如果校验失败，该Agent服务器会向请求者返回一个错误信息，并通知Manager节点。Manager节点收到错误信息后，会重新分配一个空闲的Agent服务器，并通知其它需要下载或同步文件的设备从已分配的空闲Agent服务器开始执行下载。
4)文件下载
当一个基站向Manager节点发起下载请求，Manager节点在收到该请求后，根据当前每个Agent服务器的负载状况，分配一个空闲的Agent服务器，并将连接该Agent服务器所需的信息发送给基站；其中，上述“空闲的”为相对概念，即，可以理解为所有Agent服务器中负载最小或较小的Agent服务器。此后，基站使用该信息与已分配的Agent服务器建立连接并开始下载，在下载文件的过程中，基站不会再与Manager节点通信，除非连接未能建立或下载过程出现异常等原因而导致下载失败。
5)负载均衡
Manager节点周期性地轮询所有Agent服务器，收集每个Agent服务器的负载状况。当有新的基站向该Manager节点发起下载请求时，Manager节点将一个当前负载最小的Agent服务器分配给该基站。
在本应用实例中，设计了一种弹性伸缩、可扩充的技术方案，在需要时可便捷地加入或移除文件分发服务器，以满足各种场景的需求。采用统一的控制入口，简化了外部接口，便于部署；另一方面，通过将控制流和数据流分开，解决了文件分发系统在性能方面的瓶颈问题。
