A preliminary simulation of the effect of scanning worm activity on multicast

Previous scanning worms have been significant sources of network congestion and have had catastrophic effects on switches, routers and end-systems. In this paper, we focus on the simulation of the secondary resource-exhaustion effects that scanning worms cause on network protocols operating in Internet routers. Specifically, we describe a preliminary simulation study on the effect of the spread of the Ramen and SQL Slammer/Sapphire worms on the multicast infrastructure.
