Zusammenfassung:A block transmission system for a multi-cloud, an effective bandwidth estimation method for transmitting block data, a control message generation method, and a tree information transmission method are disclosed. The effective bandwidth estimation method comprises the steps of: calculating, during a generation cycle of the block according to a Gaussian model block, transmission time for completing transmission of the previous block with a preset success probability before the next block is generated; and estimating an effective bandwidth on the basis of the number of transactions included in the block, the size of the transaction, the size of a block header, and the block transmission time. Sont divulgués un système de transmission de bloc pour un nuage multiple, un procédé d'estimation de bande passante efficace pour transmettre des données de bloc, un procédé de génération de message de commande et un procédé de transmission d'informations d'arbre. Le procédé d'estimation de bande passante efficace comprend les étapes consistant à : calculer, pendant un cycle de génération du bloc selon un bloc de modèle gaussien, un temps de transmission pour achever la transmission du bloc précédent avec une probabilité de réussite prédéfinie avant que le bloc suivant ne soit généré ; et estimer une bande passante efficace sur la base du nombre de transactions incluses dans le bloc, de la taille de la transaction, de la taille d'un en-tête de bloc et du temps de transmission de bloc. 멀티 클라우드의 블록 전송 시스템과 블록 데이터 전송을 위한 유효 대역폭 추정 방법과 제어 메시지 생성 방법 및 트리 정보 전달 방법이 개시된다. 유효 대역폭 추정 방법은, 가우시안 모델을 따르는 블록의 생성 주기에서, 다음 블록의 생성 전에 기설정된 성공 확률로 이전 블록의 전송을 완료하기 위한 블록 전송 시간을 계산하는 단계, 및 블록에 포함되는 트랜잭션 개수와 트랜잭션 크기와 블록 헤더 크기 및 블록 전송 시간에 기초하여 유효 대역폭을 추정하는 단계를 포함한다.
