Abstract Since FMIPv6 establishes extended tunnel just after the link down trigger, there may not be enough time to extend the tunnel to the next access point, especially when the mobile node moves fast; and packet drop will occur until the tunnel is re-established from the home agent to the mobile node through the next access router. In this paper, we propose a new approach called Early Binding Fast Handover (EBFH) that reserves several extended tunnels with expected next access routers (NARs) beforehand, activates one of the extended tunnels when the link going down trigger is generated. The proposed scheme minimizes the packet drop during overall handover procedure, and can provide QoS guaranteed real-time services to mobile nodes which move fast. Keywords: MIPv6, L2 Trigger, Fast handover, Real-Time Traffic, QoS-guarantee
