Figure 11: Typical profile for a TCP flow showing the data rate (bytes/sec) at the MN, with WAN to LAN handoff. There was an interruption during the MN handoff for MIPv6, while there was no interruption for ILNPv6. The data rate increased after the handoff due to a lower delay link, except MIPv6 without RO, where the traffic still traversed the high-delay link because of the tunnel to the HA.
