Distributed publish/subscribe systems are usually deployed on top of
an overlay network that enables complex routing strategies
implemented in the application layer. Up to now, only little effort
has been spent on the design of the broker overlay network assuming
that it is either static or manually administered. As
publish/subscribe systems are increasingly targeted at dynamic
environments where client behavior and network characteristics vary
over time, static overlay networks lead to suboptimal performance.
In this paper, we present a self-organizing broker overlay
infrastructure that adapts dynamically to achieve a better
efficiency on both, the application and the network layer. This is
obtained by taking network metrics as well as notification traffic
into account.
