This paper discusses the impact of increased signaling traffic fueled by increasing mobile broadband and machine-to-machine (M2M) connectivity on networks, systems and processors. While data offload strategies have received considerable attention in industry, the impact of signaling overload and mitigation strategies have not been widely addressed. A good understanding of the reasons for signaling traffic increases, its impact at the network level, system level and processor level is needed to clear misnomers prevailing in the industry. This paper looks at the issue top-down and also review strategies at the network, system and processor levels to combat the challenges of signaling overload.
