The Base Mobile-IP, the Mobile-IP with Route Optimization extension and Local Registration Mobile-IP are different approaches to supporting the mobility of IP hosts. Each one of those schemes has its own advantages and drawbacks. The route optimization solves the triangular route problem and the corresponding larger delay associated with the Base Mobile-IP with the expense of larger overhead for location management purposes. The Local Registration Mobile-IP scheme was introduced to enhance the performance by processing the MN's registration requests at a local agent. The local registration approach may effect other aspects of the Mobile-IP systems as the fault tolerance. The Base Mobile-IP and Mobile-IP with the Route Optimization schemes can be implemented on top of Hierarchical Local Registration Mobile-IP, thus it is important to tackle the issues affecting the performance in those environments. We present a mechanism to enhance the performance of the Route Optimization Mobile-IP systems and a platform to support foreign agents fault tolerance in systems supporting local registration
