Building the Mobile Internet

Chapter 7. Application Mobility

The previous chapters have described techniques for solving the mobility problem using solutions for routing packets toward a particular device using IP identities (addresses) as endpoint identifiers. Application mobility looks to solve the mobility problem using non-IP identities as personal identifiers.

Note

There might be a 1-to-1 relationship between a “personal identifier” and a particular user, an N-to-1 relationship where a particular user has multiple personal identifiers, or a 1-to-N relationship where a single personal identifier is shared among multiple users.

Solving mobility using non-IP personal identifiers allows the focus of mobility to switch from the endpoint or device toward the person. This ...
