Abstract

Orphan detection methods demonstrate different performance, memory consumption in different scenarios. Dedicated Server Group (DSG) method is one of the most proper one. In this paper, we overviewed DSG method and analyzed its advantages and disadvantages. Based on the analytical results, we improved the DSG method in both process overhead and communication/traffic overhead. The dependability of improved method is evaluated by Markov chain modeling using SHARPE package and the Availability, Reliability, and Mean-Time to Failure are calculated.
