Overload management is of vital importance in wide-area publish/subscribe systems, yet current solutions are best-effort. In this paper, we present an admission control scheme for overload management in large-scale and scalable content-based publish/subscribe systems. We analyze the stumbling block for implementing admission control in publish/subscribe systems, and point out how it differs from admission control schemes in other research areas. We propose a <i>cover</i> relation based algorithm to compute subscription resource requirements, and an admission control algorithm based on subscription routing. The scheme ensures time, space and flows decoupling without sacrificing scalability of publish/subscribe systems. Finally, we conduct experiments to verify the effectiveness of the scheme.
