Abstract:
(EN) Provided are a node distribution method and a management server for performing same. Here, the node distribution method is a method for node distribution performed by a management server operated by at least one processor, the method comprising the steps of: allocating a plurality of nodes, which transmit an image, to a plurality of streaming servers, which receive the image and transmit the received image to a client terminal, by using a distributed hash table (DHT or DHTs) so that the plurality of nodes and the plurality of streaming servers are distributedly connected; monitoring the states of each of the plurality of streaming servers; releasing connections between a first streaming server, the monitored state of which satisfies a predefined condition, and the plurality of nodes connected to the first streaming server; and reallocating, by using the distributed hash table, the plurality of connection-released nodes to at least one second streaming server among the streaming servers remaining after excluding the first streaming server.
(FR) La présente invention concerne un procédé de distribution de nœuds, et un serveur de gestion exécutant le procédé. Le procédé de distribution de nœuds selon l'invention est un procédé de distribution de nœuds exécuté par un serveur de gestion commandé par au moins un processeur. Le procédé comprend les étapes consistant à : attribuer une pluralité de nœuds, qui transmettent une image, à une pluralité de serveurs de diffusion en continu, qui reçoivent l'image et transmettent l'image reçue à un terminal client, au moyen d'une table de hachage distribuée (DHT ou DHTs) de sorte que la pluralité de nœuds et la pluralité de serveurs de diffusion en continu sont connectés de manière distribuée; surveiller des états de la pluralité de serveurs de diffusion en continu, respectivement; libérer une connexion entre un premier serveur de diffusion en continu, dont l'état surveillé satisfait une condition prédéfinie, et une pluralité de nœuds connectés au premier serveur de diffusion en continu; et réattribuer, au moyen de la table de hachage distribuée, la pluralité de nœuds dont la connexion a été libérée, à au moins un second serveur de diffusion en continu parmi les serveurs de diffusion en continu restants à l'exclusion du premier serveur de diffusion en continu.
(KO) 노드 분산 방법 및 이를 수행하는 관리 서버가 제공된다. 여기서, 노드 분산 방법은 적어도 하나의 프로세서에 의해 동작하는 관리 서버에서 수행되는 노드 분산 방법으로서, 영상을 전송하는 복수의 노드와 상기 영상을 수신하여 클라이언트 단말로 전송하는 복수의 스트리밍 서버가 분산 연결되도록, 분산 해시 테이블(Distributed Hash Tables, DHT 또는 DHTs)을 이용하여 상기 복수의 스트리밍 서버에 상기 복수의 노드를 할당하는 단계, 상기 복수의 스트리밍 서버 각각의 상태를 모니터링하는 단계, 모니터링한 상태가 기 정의된 조건을 충족하는 제1 스트리밍 서버와 연결된 복수의 노드와 상기 제1 스트리밍 서버 간의 연결을 해제시키는 단계, 그리고 연결이 해제된 복수의 노드를 상기 제1 스트리밍 서버를 제외한 나머지 스트리밍 서버들 중 적어도 하나의 제2 스트리밍 서버에 상기 분산 해시 테이블을 이용하여 재할당하는 단계를 포함한다.
