Summary:
In the near future, undetectable malware programs may infect routers. Even such programs can be removed by initializing routers. However, packet forwarding needs to be suspended during the initialization. To solve this problem, we have been studying a metabolic router. This hardware router comprises multiple virtual routers redundantly. The master virtual router is exchanged periodically with the initialized backup one. Despite that malware is undetectable or not, this exchange removes the infected malware from the hardware router. This paper evaluates this exchanging scheme through experiment. The results are as follows: (1) VRRP can exchange virtual routers within 1 millisecond. (2) This exchange can be repeated semi-permanently by periodically decreasing the priority levels of the exchanged virtual routers. (3) This exchange removes malware from the hardware router. Consequently, it is expected that the router metabolism can mitigate malware infection damage.
