BLOCKING COMMUNICATION GRID VIA ILL-INTENTIONED TRAFFIC

摘要

A rectangular communication grid model was constructed in the form of a colored Petri net as a composition of submodes of terminal devices producing and consuming packets and communication devices switching packets for their delivery among terminal devices. The model was supplied with traffic guns simulating ill-intentioned traffic. Via simulation in CPN Tools it was shown that a traffic duel of a pair of guns brings the grid to a full deadlock with less than ten percent of the peak load. Thus, the vulnerability of grids to traffic attacks was revealed. The future work is aimed to resist the attacks.
