Abstract

The application provides a method for constructing a data source address distribution tree. The method comprises the following steps: receiving a request of inquiring kinship node information of a requester in a specified data source address distribution tree sent by the requester, wherein the requester is determined by an identifier of the requester, and the specified data source address distribution tree is determined by a data source address distribution tree identifier; adding the requester into the data source address distribution tree as a new node; and transmitting information of a parent node and a child node of a node corresponding to the requester to the requester. Through adoption of the method, the effects of saving data source address storage space, simplifying a data source address storage structure and dynamically adapting to the changes of the nodes in a network are achieved; the running and maintenance cost is lowered; and the adaptability to node changes becomes more flexible.

Description

technical field

[0001] This application relates to a tree construction method, in particular to a data source address distribution tree construction method and device; this application also relates to a method and device for copying data, and this application also relates to a method for updating the node storage The method and device for distributing the parent node information of the current node in the specified data source address tree; the present application also relates to a method and device for data transmission; the present application also relates to a data source address distribution system. Background technique

[0002] For large-scale computer networks with many nodes, deploying software or copying data files on multiple nodes in the network is an essential operation for business systems running on computing networks. When running business systems based on large-scale distributed computer systems, It is often necessary to copy the same large-scale software or t...
