Evaluation of link layer mobility in Ethernet networks

Our evaluation shows that while host mobility without any explicit signaling will remain a best-effort service in Ethernet networks, we can significantly improve its efficiency and reliability in certain use cases, while providing improved scalability and safety properties. We also show that while the host mobility support in DBridges suffers from transient forwarding loops, the problem is exceedingly rare in real networks and is mitigated by the base functionality in routing bridges.
