This paper proposes a new approach for handling overload
in Publish/Subscribe systems. We focus on the fact that every service has
to cope with the limitations imposed by the external environment (e.g.,
network congestion) and the limitations resulting directly from within
the service itself – e.g., the maximum available computational power.
This work seeks to aid Publish/Subscribe mechanisms with the ability to
handle both aforementioned constraints in a graceful way, simultaneously
ensuring for the most valuable information to be given the highest chance
of a successful delivery.
