STRESS: An IPv6 to IPv4 Converter for Sniffing Software

IPv4 is now being replaced by IPv6 gradually, which means that a lot of software specific to IPv4, such as sniffing software, need to be upgraded to adjust to IPv6. However, due to the big difference between IPv4 and IPv6, it is expensive and time consuming to upgrade an existed stable product. We design and implement STRESS, an IPv6 to IPv4 converter for sniffing software to make these products keep working during the transition time. STRESS handles received IPv6 packets, rewrite them to IPv4 packets, and send them back to IPv4 based software. After such process, the old IPv4 software can now identify contents in IPv6 packets properly.
