Les +nœuds connectés à un même réseau peuvent envoyés et recevoir en multicast des +messages. Il existe quatre types de messages : + +* LookUp qui permet de demander à tous les noeuds, étant donné un chemin, + si un fichier existe ; +* LookUpResponse qui est envoyé si un nœud suite à la réception d'un LookUp, + constate qu'il est en possession du fichier demandé. Avant la réponse, on + calcule à partir du fichier un descripteur (FileDescription) comprenant + diverses informations nécessaire à l'échange du fichier (taille totale, + somme de contrôle, nombre de parties) ; +* FileRequest est éventuellement envoyé après réception d'un LookUpResponse, + il vise à demander l'envoi des données d'un fichier ; +* La réception d'un FileRequest, génère l'envoi, en réponse, de message de types + FileTransfer. Chacun d'eux contient une partie du fichier. + +Ainsi, ce protocole permet : + +* la recherche d'un fichier pour un chemin donné dans une arborescence ; +* si besoin, son téléchargement ; +* la réplication. + +Ce protocole ne permet pas : + +* Lister le contenu d'un répertoire ; +* Utiliser des liens symboliques. + +Cela n'est pas rendu possible par l'absence d'informations communes et +synchronisées entre les nœuds. Pour remédier à ce problème, il semble qu'une +voie possible serait de répliquer entre tous les nœuds l'intégralité de +l'arbre décrivant l'arborescence[1]_ et de ne pratiquer l'échange des données +des fichiers qu'au moment opportun[2]_. + +Ce premier prototype a été implémenté grâce à JGroups. +Il est fonctionnel s'il s'agit d'avoir un système de +fichier partagé et si on lit et écrit dans l'arborescence à des chemins connus +à l'avance. C'est trop limité pour un système de fichier. + +.. [1] voir le building block `ReplicatedTree <http://www.jgroups.org/javadoc/org/jgroups/blocks/ReplicatedTree.html>`_. +..
