When should i make preservation copies of myself?

摘要

We investigate how different replication policies ranging from least aggressive to most aggressive affect the level of preservation achieved by autonomic processes used by web objects (WOs). Based on simulations of small-world graphs of WOs created using the Unsupervised Small-World algorithm, we report quantitative and qualitative results for graphs ranging in order from 10 to 5000 WOs. Our results show that a moderately aggressive replication policy makes the best use of distributed host resources by not causing spikes in CPU resources nor spikes in LAN activity while meeting preservation goals.
