Definitions

  • some nodes may leave the network actively or for some reason, which may easily cause loss of storage resources.
  • the node used to back up a resource is called the backup node of this resource.
  • the use of backup resources increases the availability of resources, but backup resources are also lost due to the failure of backup nodes.
  • the resources stored in the root node also face this problem. Therefore, a method is needed to protect important storage resources from loss when the node fails.
  • Step 502 The root node detects that a backup node is invalid or receives an exit request of a backup node.
  • This step can be done by the backup node that first finds the new root node, or by the backup node selected by the new root node.
  • the root node may further include:

Abstract

L'invention concerne un procédé, un nœud de réseau et un système pour sauvegarder une ressource dans un réseau P2P structuré. Le procédé comporte les étapes suivantes : le nœud de sauvegarde se fonde sur le mécanisme de détection créé ; s'il est détecté que le nœud racine échoue, le nœud de sauvegarde acquiert un nouveau nœud racine dans le réseau P2P structuré selon la valeur de marquage à laquelle correspond la ressource ; le nouveau nœud racine stocke les informations d'indice de chaque nœud de sauvegarde.
