具体实施方式
以下为更进一步阐述本申请为达成预定目的所采取的技术手段及功效，以下结合附图及较佳实施例，对本申请进行详细说明如后。
如图1所示，机顶盒(数字视频变换盒)在数据通讯网络交互过程中，至少存在两次不同环境中的地址通讯过程，包括：
步骤S101，机顶盒发送第一报文至宽带接入路由器，宽带接入路由器将第一报文发送至管理服务器，管理服务器返回管理通信地址给宽带接入路由器，宽带接入路由器返回管理通信地址给机顶盒。
在实际应用中，第一报文可以为DHCP Discover报文，机顶盒管理地址分配过程，即机顶盒首次加电后，携带厂商初始化信息发送DHCP Discover报文至宽带接入路由器(DHCP Relay中继服务器)，宽带接入路由 器根据DHCP Discover报文携带的信息内容，判定该机顶盒为初始状态，并将DHCP Discover报文发送至管理服务器(DHCP Server#1)；管理服务器(DHCP Server#1)下发通讯用机顶盒地址(即管理通信地址)，版本机地址，及相关配置服务器简单文件传输协议(Trivial File Transfer Protocol,TFTP)地址，通知机顶盒下载，机顶盒获取管理通信地址IP#1。
步骤S102，机顶盒发送第二报文给宽带接入路由器，宽带接入路由器发送第二报文给管理服务器。
在实际应用中，第二报文可以为DHCP Release报文。机顶盒下载新版本及业务数据后，进行机顶盒重启操作。机顶盒重启操作需要发送DHCP Release报文至宽带接入路由器，通知宽带接入路由器、管理服务器释放管理通信地址IP#1资源。
步骤S103，机顶盒发送第一报文至宽带接入路由器，宽带接入路由器将第一报文发送至管理服务器，管理服务器返回业务通讯地址给宽带接入路由器，宽带接入路由器返回业务通讯地址给机顶盒。
在实际应用中，第一报文可以为DHCP Discover报文，机顶盒业务地址分配过程，即机顶盒将携带用户业务信息的DHCP Discover报文发送至宽带接入路由器，宽带接入路由器根据DHCP Discover携带的信息内容，判定机顶盒已经完成数据初始化，已经获取本次请求业务通讯地址；宽带接入路由器将数据发往业务管理服务器(DHCP Server#2)；业务管理服务器(DHCP Server#2)下发业务通讯地址，机顶盒获取业务通讯地址IP#2；机顶盒完成业务通讯地址分配，开始进行正常业务互访。
如图2所示，机顶盒(数字视频变换盒)在数据通讯网络交互过程中，在两次不同环境中管理通信地址与业务通信地址切换过程中出现挂死，包括：
步骤S201，机顶盒发送第一报文至宽带接入路由器，宽带接入路由器将第一报文发送至管理服务器，管理服务器返回管理通信地址IP#1给宽带 接入路由器，宽带接入路由器返回管理通信地址IP#1给机顶盒。
机顶盒管理地址分配过程，即机顶盒首次加电后，携带厂商初始化信息发送DHCP Discover报文至宽带接入路由器(DHCP Relay中继服务器)，宽带接入路由器根据DHCP Discover报文携带的信息内容，判定该机顶盒为初始状态，并将DHCP Discover报文发送至管理服务器(DHCP Server#1)；管理服务器(DHCP Server#1)下发通讯用机顶盒地址，版本机地址，及相关配置服务器TFTP(Trivial File Transfer Protocol,简单文件传输协议)地址，通知机顶盒下载，机顶盒获取管理通信地址IP#1。
步骤S202，机顶盒发送第二报文失败，宽带接入路由器发送第二报文失败。
在实际应用中，第二报文可以为DHCP Release报文。机顶盒设备在重新启动加载新数据前，需要发送DHCP Release报文，通知宽带接入路由器及管理服务器释放在步骤S201过程中占用的会话管理资源；由于机顶盒实现或者链路稳定性因素等原因，会出现DHCP Release报文没有发送、发送内容错误或者发送过程中丢失情况，导致宽带接入路由器及管理服务器没有如期收到会话管理资源释放请求，会话管理资源继续被占用。
步骤S203，机顶盒发送第一报文至宽带接入路由器，宽带接入路由器将第一报文发送至管理服务器，管理服务器返回管理通信地址给宽带接入路由器，宽带接入路由器返回管理通信地址给机顶盒。
机顶盒设备重启后发送DHCP Discover报文,请求业务通讯地址，宽带接入路由器收到DHCP Discover报文后，发现机顶盒与管理服务器通讯连接仍然存在，数据报文会投递到管理服务器进行地址重新申请；管理服务器收到请求报文后，发现给机顶盒分配的管理通信地址IP#1仍然在正常使用，管理服务器使用管理通信地址IP#1进行回复，将机顶盒分配到管理通信地址IP#1；机顶盒当前获取地址为IP#1，IP#1为管理网络使用的管理通信地址，在业务通讯网络中无法识别管理地址IP#1，机顶盒出现挂死现 象。此时，需等待宽带接入路由器和管理服务器上DHCP协议老化，机顶盒才能分配正常地址，过程中机顶盒重启不能解决挂死问题。
如图3所示，机顶盒(数字视频变换盒)在快速上线过程中，在两次不同环境中管理通信地址与业务通信地址切换过程中出现挂死，包括：
步骤S301，机顶盒发送第一报文至宽带接入路由器，宽带接入路由器将第一报文发送至管理服务器，管理服务器返回管理通信地址IP#1给宽带接入路由器，宽带接入路由器返回管理通信地址IP#1给机顶盒。
以第一报文为DHCP Discover报文为例，机顶盒管理地址分配过程，即机顶盒首次加电后，携带厂商初始化信息发送DHCP Discover报文至宽带接入路由器(DHCP Relay中继服务器)，宽带接入路由器根据DHCP Discover报文携带的信息内容，判定该机顶盒为初始状态，并将DHCP Discover报文发送至管理服务器(DHCP Server#1)；管理服务器(DHCP Server#1)下发通讯用机顶盒地址，版本机地址，及相关配置服务器TFTP(Trivial File Transfer Protocol,简单文件传输协议)地址，通知机顶盒下载，机顶盒获取管理通信地址IP#1。
步骤S302，机顶盒发送第二报文失败，宽带接入路由器发送第二报文失败。
以第二报文为DHCP Release报文为例，机顶盒在重新启动加载新数据前，需要发送DHCP Release报文，通知宽带接入路由器及管理服务器释放在步骤S301过程中占用的会话管理资源；由于机顶盒实现或者链路稳定性因素，会出现DHCP Release报文没有发送、发送内容错误或者发送过程中丢失情况，导致宽带接入路由器及管理服务器没有如期收到会话管理资源释放请求，会话管理资源继续被占用。
步骤S303，机顶盒发送第三报文至宽带接入路由器，宽带接入路由器将第三报文发送至管理服务器，管理服务器返回管理通信地址IP#1给宽带接入路由器，宽带接入路由器返回管理通信地址IP#1给机顶盒。
这里，第三报文可以为DHCP Request报文，机顶盒重启后，会进入快速上线过程。快速上线为DHCP协议定义的一种快速拨号方式，快速上线过程不会发送DHCP Discover报文，直接发送DHCP Request报文，报文采用广播方式发送，宽带接入路由器收到DHCP Request报文后，发现机顶盒与管理服务器通讯联接仍然存在，DHCP Request报文会向管理服务器进行投递；管理服务器收到DHCP Request报文后，发现给机顶盒分配的管理通信地址IP#1仍然在正常使用，管理服务器使用管理通信地址IP#1进行回复，机顶盒将分配到管理通信地址IP#1。
机顶盒当前获取地址为管理通信地址IP#1，管理通信地址IP#1为管理网络使用地址，在业务通讯网络中无法识别管理通信地址IP#1，机顶盒在快速上线过程中出现挂死现象；此时，需等待宽带接入路由器和管理服务器上DHCP协议老化，机顶盒才能分配正常地址，过程中机顶盒重启不能解决挂死问题。
