A METHOD FOR SEARCHING NODES FOR INFORMATION

摘要

A method by which one node can search for and retrieve information from another node. A message identifying the sought-for information item and an address is created at a first node. The address identifies a repository for the sought-for information. A second node receives the contents of this message and responds with the information item if the item is available. Otherwise, the second node propagates the message to other nodes. The message is propagated from node to node until it reaches a node having the sought-for information item. If this node can connect to the specified address, it sends the information item to the repository. Otherwise, the node adds the information item to the message, which is propagated to other nodes until the message reaches a node that can connect with the address. The information item can then be retrieved from the repository.
