本技术报告的目的是列举应在灾难发生之前、期间和之后立即执行的潜在主动或自动策略驱动的网络流量管理操作。灾难情况会导致网络过载。因此，重要的是，本文件应包括在超载情况下（无论是否由灾难引发）NGN流量管理措施的参考或文件。

The purpose of this technical report is to enumerate potential proactive or automatic policy-driven network traffic management actions that should be performed prior to, during, and immediately following disaster conditions. Disaster conditions cause network overload. Consequently it is important that this document include reference to or documentation of NGN traffic management actions in overload situations whether triggered by disaster or not.
