摘要
As a plethora of various distributed applications emerge, new computing platforms are necessary to support their extra and sometimes evolving requirements. This research derives its motive from deficiencies of real networked applications deployed on platforms unable to fully support their characteristics and proposes a network architecture to address that issue. Hoverlay is a system that enables logical movement of nodes from one network to another aiming to relieve requesting nodes, which experience high workload. Node migration and dynamic server overlay differentiate Hoverlay from Condor-based architectures, which exhibit more static links between managers and nodes. In this paper, we present a number of important extensions to the basic Hoverlay architecture, which collectively enhance the degree of control owners have over their nodes and the overall level of cooperation among servers. Furthermore, we carried out extensive simulations, which proved that Hoverlay outperforms Condor and Flock of Condors in both success rate and average successful query path length at a negligible increase in messages.
