The goal of this thesis is to define a set of changes to the TCP/IP stack that allow connections between legacy applications to be sustained in a contemporary heterogeneous datacom environment embodying multiple granularities of mobility. In particular, the thesis presents a number of solutions for flow mobility, local mobility, network mobility, and address family agility that is mobility between different IP versions. The presented mobility solutions are based on the so-called identifier-locator split approach. Due to the split, the mobile and multi-homed hosts that employ the presented solution are able to simultaneously communicate via multiple access networks, even supporting different IP versions and link layer technologies. In addition to the mobility solutions, the thesis also defines a set of weak and strong security mechanisms. They are used to protect the mobility protocols from redirection, Denial-of-Service (DoS), and privacy related attacks. The defined security mechanisms are tightly bound to the presented mobility architecture, providing alternative ways to optimize mobility management signalling. The focus is on minimizing end-to-end signalling latency, optimizing the amount of signalling and optimizing packet forwarding paths. In addition, the architecture provides identity and location privacy for hosts. The presented work defines one specific kind of engineering balance between the security, privacy, and efficient mobility signalling requirements. This thesis indicates that the added security, indirection, backwards compatibility, and inter-operable mobility solutions can overcome several of the current TCP/IP restrictions. The presented mobility architecture also provides a migration path from the existing Internet architecture to a new cryptographic-identifier-based architecture.
