%X To meet the requirement of Web services' dynamic distribution and maintain the consistency of Web services migration was provided.A Broker-based Web services migration algorithm(WS Broker) was proposed.WS Broker guarantees the migration consistency and improves the migration performance.In addition,by analyzing the dependency relationship among the requests interrupted by the migration,WS Broker could process some of them in advance,which greatly reduces the total latency of request processing caused by the migration.The result of the test showes that WS Broker improves the perfor-mance of Web services migration efficiently.
