Abstract
In order to overcome the defects of the centralized subscriber data management in the telecommunication network, a highly effective distributed data management system for the communication network is achieved in the present invention through improving and applying the distributed Hash table (DHT) technology to subscriber data management in the communication network, which overcomes the deficiencies of the conventional centralized data management. A method for processing subscriber data in a communication network based on a DHT is provided, which includes the following steps. A first node in a DHT overlay network receives subscriber data to be stored. The subscriber data to be stored is regarded as backup data divided into L/K portions. L is greater than or equal to a ratio of a node working bandwidth of a second node to a node recovering bandwidth for data recovery of the second node in the DHT overlay network. K is a total number of backup data and is an integer greater than zero. The subscriber data to be stored is regarded as master data, and the master data and K×L/K divided backup data are, respectively, stored in 1+K×L/K DHT nodes.
