Zusammenfassung:	The present invention relates to a method for selecting a leader controller in a decentralized software-defined network. The method includes the steps of: calculating a stability value for mobility of each of a plurality of controller nodes; generating a two-layer virtual loop in and out of a plurality of domains based on the calculated stability value; and synchronizing information about each node in and out of the plurality of domains based on the two-layer virtual loop. Accordingly, a load applied to a reader can be reduced. 본 발명은 분산형 소프트웨어 정의 네트워크에서의 리더 컨트롤러 선택 방법에 관한 것으로서, 상기 방법은 복수의 컨트롤러 노드 각각의 이동성에 대한 안정성 값을 산출하는 단계; 상기 산출된 안정성 값을 기반으로 복수의 도메인 내외에서의 2 계층 가상 고리를 생성하는 단계; 및 상기 2 계층 가상 고리에 기반하여 복수의 도메인 내외에서의 각 노드에 대한 정보를 동기화하는 단계를 포함한다.
