Abstract
(EN) A node device (1A) receives a second ACK list in communication with an adjacent node (1B) and updates a first ACK list and a first summary vector on the basis of the second ACK list. The first summary vector, which indicates messages stored in a message buffer of the node device (1A), is transmitted to the adjacent node (1B) prior to transmission of the messages in the communication with the adjacent node (1B). The first ACK list indicates ACK messages recognized by the node device (1A). The second ACK list indicates ACK messages recognized by the adjacent node (1B). Each ACK message represents a message of arrival at an ultimate destination node via a DTN (100). In this way, for example, a copy having the same content as a message having arrived at an ultimate destination node can be prevented from being scattered in the Disruption Tolerant Network (DTN).
(FR) Selon l'invention, un dispositif de nœud (1A) reçoit une seconde liste d'accusés de réception (ACK) en communication avec un nœud adjacent (1B) et met à jour une première liste d'ACK et un premier vecteur de résumé sur la base de la seconde liste d'ACK. Le premier vecteur de résumé, qui indique des messages stockés dans une mémoire tampon de messages du dispositif de nœud (1A), est transmis au nœud adjacent (1B) avant la transmission des messages dans la communication avec le nœud adjacent (1B). La première liste d'ACK indique des messages d'ACK reconnus par le dispositif de nœud (1A). La seconde liste d'ACK indique des messages d'ACK reconnus par le nœud adjacent (1B). Chaque message d'ACK représente un message d'arrivée au niveau d'un nœud de destination ultime par l'intermédiaire d'un réseau tolérant aux perturbations (DTN) (100). De cette manière, par exemple, une copie ayant le même contenu qu'un message arrivé au niveau d'un nœud de destination ultime peut être empêchée d'être diffusée dans le réseau tolérant aux perturbations (DTN).
(JA) ノード装置(1A)は、隣接ノード(1B)との交信において第2のACKリストを受信し、第1のACKリスト及び第1のサマリベクタを第2のACKリストに基づいて更新する。第1のサマリベクタは、ノード装置(1A)のメッセージバッファに保存されたメッセージを示し、隣接ノード(1B)との交信においてメッセージの送信に先立って隣接ノード(1B)に送信される。第1のACKリストは、ノード装置(1A)によって認識されているACKメッセージを示す。第2のACKリストは、隣接ノード(1B)によって認識されているACKメッセージを示す。各ACKメッセージは、DTN(100)を経由して最終的な宛先ノードに到達済みのメッセージを示す。これにより、例えば、最終的な宛先ノードに到達したメッセージと同じ内容を持つ複製がDisruption Tolerant Network(DTN)内に拡散されることを抑制する。
