This book examines the different techniques for building mobility into the Internet. The breadth of approaches currently in operation should cause us all to pose the question as to whether, in the future, a single utopian mobility solution can be defined that accommodates all scenarios, or whether solving “mobility” requires a decomposition of the “mobility problem space” into a number of distinct use cases.

The tremendous success of mobile broadband–based services based on cellular architectures where mobility has been effectively performed at the data link layer has shown how that approach is perfectly acceptable for providing wide-area mobility to use cases involving a single device with a single interface.

Should such data link ...
