What is it about?
The direct and flexible use of any network connectivity that is available within an urban scenario is essential for the suc- cessful operation of ubiquitous systems. We demonstrate seamless communication across different networks without the use of middleware, proxies, tunnels, or address translation, with minimal (near-zero) packet loss to communication flows as handoff occurs between networks.

Why is it important?
Our solution does not require any new functions in existing net- works, will work on existing infrastructure, and does not re- quire applications to be re-designed or re-engineered. Our solution requires only modifications to the end-systems in- volved in communication, so can be deployed incrementally only for those end-systems that require the functionality.
Perspectives
Our solution uses the Identifier-Locator Network Protocol (ILNP), implemented as a superset of IPv6. We used a testbed consisting of commercial equipment to demonstrate that the approach is deployable on today's network equipment without upgrades -- only those end-systems that want to be mobile or communicate with mobile nodes need to be updated.
