    • Example methods and apparatus to control synchronization in voice over Internet protocol (VoIP) networks after catastrophes are disclosed. An example border element comprises a network interface to receive a VoIP network registration request message from a VoIP endpoint, a catastrophe detector to determine whether a catastrophe has been detected, a backoff time module to compute a backoff time using a priority assigned to the VoIP endpoint and an expected number of VoIP network registration request messages, a recovery module to determine whether the VoIP endpoint is currently registered with the VoIP network, and to send a response message having a header representing the backoff time to the VoIP endpoint when the catastrophe has been detected and the VoIP endpoint is not currently registered with a VoIP network, and a signaling processor to process the VoIP network registration request message when the VoIP endpoint is currently registered with the VoIP network.
    • 公开了在灾难发生后控制语音互联网协议(VoIP)网络同步的示例方法和装置。 示例性边界元素包括从VoIP端点接收VoIP网络注册请求消息的网络接口,用于确定是否已经检测到灾难的灾难检测器,使用分配给所述VoIP终端的优先级来计算退避时间的退避时间模块 以及VoIP网络注册请求消息的预期数量,用于确定VoIP端点是否正在向VoIP网络注册的恢复模块,并且当灾难已经被发送时,将具有表示退避时间的报头的响应消息发送到VoIP端点 并且VoIP端点当前未注册到VoIP网络,以及当VoIP端点当前已经向VoIP网络注册时处理VoIP网络注册请求消息的信令处理器。
