Method and apparatus for initializing a new node in a network

摘要

A method for initializing a new node in a network. The network has multiple nodes arranged in a virtual tree format. The new node is a node of the tree, and each node of the tree has a set of attributes and a set of rolled up attributes to identify each node. A query is automatically sent to the nodes to determine what contents to download. The contents are then stored as block files in the nodes. The query contains the set of attributes and rolled up attributes for the new node. The query receives replies from a subset of the nodes that have the contents needed for the new node. Each reply identifies what subset of the block files is available and the performance characteristics of that replying node. Then the desired contents from the subset of the block files from nodes that are least congested is downloaded.
