Abstract
Network-enabled mobile devices are quickly becoming ubiquitous in the
lives of ordinary people, but current technologies for providing
ubiquitous global *connectivity* between these devices still require
experts to set up and manage. Users must allocate and maintain global
domain names in order to connect to their devices globally via DNS,
they must allocate a static IP address and run a home server to use
Mobile IP or set up a virtual private network, they must configure
firewalls to permit desired remote access traffic while filtering
potentially malicious traffic from unknown parties, and so on. This
model of "management by experts" works for organizations with
administrative staff, but is infeasible for most consumers who wish to
set up and manage their own personal networks.
The Unmanaged Internet Architecture (UIA) is a suite of design
principles and experimental protocols that provide robust, efficient
global connectivity among mobile devices while relying for
configuration only on simple, intuitive management concepts. UIA uses
"personal names" rather than traditional global names as handles for
accessing personal devices remotely. Users assign these personal
names via an ad hoc device introduction process requiring no central
allocation. Once assigned, personal names bind securely to the global
identities of their target devices independent of network location.
Each user manages one namespace, shared among all the user's devices
and always available on each device. Users can also name other users
to share resources with trusted acquaintances. Devices with naming
relationships automatically arrange connectivity when possible, both
in ad hoc networks and using global infrastructure when available.
We built a prototype implementation of UIA that demonstrates the
utility and feasibility of these design principles. The prototype
includes an overlay routing layer that leverages the user's social
network to provide robust connectivity in spite of network failures
and asymmetries such as NATs, a new transport protocol implementing a
novel stream abstraction that more effectively supports the highly
parallelized and media-oriented applications demanded on mobile
devices, and a flexible security framework based on proof-carrying
authorization (PCA) that provides "plug-in" interoperability with
existing secure naming and authentication systems.
