The Analysis and Verification of IPv4/ IPv6 Protocol Conversion by Petri Nets

Abstract

IPv6 is designed to address the scalability and service shortcomings of the current IPv4 protocol. Unfortunately, IPv6 is not backward-compatible with the IPv4. It is necessary to consider IPv4-IPv6 protocol conversion. To resolve this problem, in the paper, we use Petri nets to simulate and model the IPv4-Pv6 protocol conversion process. By analyzing the bounded ness, activity and reversibility of the model, we prove that the process can both achieve IPv4-IPv6 conversion and satisfy system security requirements.
