Abstract

(목적)통신망에서 일단 빠진 폭주상태로 부터의 회복을 위한 제어를 통신정보가 전송되는 하위층 레벨에서 고속으로 그리고 확실하게 행하는 폭주제어방법을 제공하는 것을 목적으로 한다.
(구성)본 발명은 복수의 노드시스템을 갖는 통신망에서 제1노드로 부터 제2노드로 송출되는 통신 정보량을 감시하여 그 양이 소정의 임계치를 넘는 경우에 정보의 제2노드로의 송출을 규제하는 폭주제어방법으로서 제2노드가 폭주상태에 빠졌는가를 검출하여 이 결과에 의거해서 그 임계치를 변경하는 것이다. 또 본 발명은 단말로 부터 통신망으로 유입되는 통신 정보량을 감시하여 그 양이 소정의 임계치를 넘는 경우에 통신정보의 통신망으로서 유입을 규제하는 통신망에서의 폭주제어 방법으로서 통신망이 폭주상태에 빠졌는가를 검출하여 이 결과에 의거해서 그 임계치를 변경하는 것이다.
