In this paper, we propose a practical approach to address how micro-mobility can be provided in an efficient way with continuous Quality of Service (QoS) support. Our proposal is based on multiprotocol label switching (MPLS) and Mobile IP and relies on two-level hierarchy architecture. It supports two protocol variants. First, the fast handoff process, which anticipates the LSPs procedure setup with the neighboring locations where a mobile node (MN) may move to, is provided to reduce the service disruption. Second, a new mechanismbased on the forwarding chain concept is proposed to track efficiently the host mobility whithin a domain. This concept can significantly reduce the registration updates cost and provide low handoff latency. Analytical models are developed and simulations are conducted to justify the benefits of our proposed mechanisms.
