Implementation of an IPv6 stack for NS-3

This paper presents the implementation of an IPv6 stack within the network simulator NS-3. IPv6 is currently being deployed in the world, and will be the Internet Protocol for at least the next fifty years. On another hand, NS-3 aims at being the reference for simulation of the Internet based communication and thus it is important that NS-3 proposes a framework for IPv6. In this paper, we present the main components of our implementation and how we tackle the new mechanisms introduced by IPv6. Finally, we provide some simulation scenarios and results to show that most IPv6 features are already working in our framework, such as the Neighbor Discovery protocol.
