Home as You Go: An Engineering Approach to Mobility-Capable Extended Home Networking
Thanks to rapid technology advances, the Internet is penetrating into more homes as well as becoming increasingly mobile. In this paper, the authors describe and discuss the design choices of Apple Inc.'s Back To My Mac (BTMM) service. BTMM provides an integrated solution to host mobility support, NAT traversal, and secure end-to-end data delivery through a combination of several existing protocols and software tools. They discuss BTMM's design tradeoffs and examine its applicability as a general solution to mobility-capable extended home networks.
