TARZAN

TARZAN is an open software of Fast Handovers for Mobile IPv6(FMIPv6) which uses a link layer abstraction technique. A delay and packet loss which occur when a movement node changes a connected network have bad effect on communication. FMIPv6 is the most famous solution technique of this problem, and it becomes a foundation of many fast handover studies. However, the effectiveness of FMIPv6 and a study based on FMIPv6 in real environment are not confirmed, because there is not available implementation to the public of FMIPv6 free. Therefore we develop TARZAN, and we published it free. It is possible to run FMIPv6 fast by utilizing a change of link layer information. However, it is unclear how link layer information is used. In addition, it is very complicated to develop an extension on every device driver to obtain link layer information. Therefore we use a link layer abstraction technique and define how abstracted link layer information is used in FMIPv6 operation.
