Abstract
In this paper, we present a novel architecture to sup-
port large scale stream processing services in a widely
distributed environment. The proposed system, COSMOS,
distinguishes itself by its loose coupling and communica-
tion efficiency. To exploit the sharing of data transfer in-
curred by different queries and to break the tight coupling
of the distributed nodes, a new communication paradigm,
content-based network, is employed. We discuss the design
and the challenges of this system.
