Controlling registration floods in VoIP networks via DNS

Abstract:

A mechanism controls global synchronization, or registration floods, that may result when a large number of endpoints in a Voice over Internet Protocol (VoIP) network such as an Internet Protocol Multimedia Subsystem (IMS) come online simultaneously after a catastrophic failure. The mechanism allows the Domain Name System (DNS) infrastructure to efficiently control the overload condition by registering user end points with backup border elements, and by staggering and by randomizing the time-to-live (TTL) parameter in registrations with backup border elements.

Abstract(Chinese):

一种机制控制全球同步或注册洪水，当互联网协议多媒体子系统（IMS）上的互联网协议语音（VoIP）网络中的大量端点在灾难性故障之后同时上线时可能导致。该机制允许域名系统（DNS）基础设施通过注册具有备份边界元素的用户终点以及通过在备份边界元素的注册中随机分配生存时间（TTL）参数来有效地控制过载状况。
