There are cases where a much larger amount of traffic is added to a telecommunications network than the normal communication traffic predicted at the time of design. This is called abnormal traffic. Abnormal traffic occurs for various reasons, such as the occurrence of a social incident, ticket reservations before Golden Week, condolences for natural disasters, and sudden changes in traffic flow associated with communication network failures, and in some places, the traffic can be several to several tens of times the normal traffic. As telephones become more widespread and the number of subscribers with low calling rates, such as residential telephones, increases, these are becoming a growing problem as potential sources of abnormal traffic.

設計時に予測された平常時の通信トラヒックに比べて,はるかに多くのトラヒックが電気通信網に加えられる場合がある。これを異常トラヒックという。異常トラヒックは社会的事件の発生,ゴールデンウィーク前の切符の予約,自然災害時の見舞い,通信網の障害に付随したトラヒックの流れの急変などいろいろな原因で発生し,局部的には平常時トラヒックの数倍から数十倍に及ぶこともある。電話が普及し,住宅電話のように電話をかける率の低い加入者数が増大すればするほど,これらは潜在的な異常トラヒックの発生源として問題を大きくしつつある。
