SYSTEM AND APPARATUS FOR OPTIMALLY TRADING OFF THE REPLICATION OVERHEAD AND CONSISTENCY LEVEL IN DISTRIBUTED APPLICATIONS

摘要

It is another object to provide a method and system to trade off the optimum consistency level replication overhead in distributed data replication SOLVED node are organized in a hierarchy. Has the original data that needs to be replicated to all other nodes A1 A root node has a freshness threshold duplicate copies must satisfy. Data is propagated by regular updates in the hierarchy. Each node transmits data periodically in the child node. In view of the freshness threshold, due to the distributed algorithms and protocols, freshness threshold is met for all nodes, replicating the overall overhead to be minimized, the optimal update period for each link in the hierarchy can be determined. The system and method can be replicated and overlay resource discovery support system, a replicated data integrity requirements, to be used in any scenario. [Selection] Figure Figure 1
