Abstract: A tunnel protocol implements the encapsulation of one network protocol into another, in which the tunnel MTU is one of the key issues. This paper introduces a special IPv4-IPv6-Tunnel model, and focuses on its tunnel MTU discovery as well as the error reporting and processing mechanism. On the basis of transparency for IPv4 and IPv6 access networks, the paper analyzes and compares their respective tunnel MTU discovery process. A brief implementation of the model and some tunnel MTU experimentations are given. Finally it summarizes the model and its possible purposes.
