Abstract: | 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. |
