Core network mobility : active MPLS

This dissertation covers mobility in packet-switched wireless networks and presents a new mechanism based on Multi-Protocol Label Switching (MPLS). The mechanism is named "Active MPLS".The wireless packet-switched networks existing today (WLANs, WiMAX environments, 2.5G and 3G systems) generally offer a number of different packet-based services. When user mobility is supported, a mobile device may be moved between locations without disrupting the running data sessions. Such a movement is called a handover and is implemented by a mobility mechanism. Any mobility mechanism has the task of updating the location of the mobile device during a handover so that the data packets of the running data sessions are always sent to the correct location.Active MPLS is a mobility mechanism that does not only solve this task but that also provides for a scalable and efficient way for packet redirection during a handover. In contrast to many other mobility mechanisms, in Active MPLS packet redirection is achieved without impairing the forwarding of data packets not involved in a handover. The feasibility of Active MPLS is demonstrated through an implementation on real hardware and through simulation. A performance evaluation of Active MPLS in comparison to other mobility approaches completes the dissertation.
