Abstract The increasing availability of wireless networks and market penetration by portable computing devices require the need for a mobility solution in IP networks. Although there exists an official standard for host mobility, Mobile IP, its design does not meet the requirements of modern IP networks. Basically three problems prevent it from being widely deployed: triangular routing, greater delay because of longer routing paths and high handover latency. Various improvements have been proposed in recent years, each approach addressing some particular problem. However none of them has been accepted and became an official next-generation standard. In this master thesis, we present a real-world IP Mobility System (IPMS) that suits the needs of today's mobile users and the requirements of today's IPv4-based networks. It overcomes several original Mobile IP limitations and is a hybrid combination of multiple improvements. It allows mobile hosts to perform a (almost) seamless transition to other (sub)nets while preserving its existing sessions. We introduce the features of this system, discuss implementation details and perform the testing of critical parameters, protocols and applications. Due to a simple design of this system, it can be deployed on production basis either on a local or on a global scale. Locally it can be considered a cost-saving technology for intra-building mobility, making use of available (wireless) infrastructure consisting of different subnets. On a larger scale this technology may be valuable for Internet Service Providers (ISP) wishing to offer IP roaming services for clients from other networks. Moreover, because of its fast handovers, the IPMS can also be used in moving vehicles and trains provided there is sufficient wireless coverage.
