ability to handle the scalability challenges of increasing numbers of content
items (in the form of router entries) and
providers (in the form of router caches).
Whereas this is a significant problem
in fixed infrastructure, it is even more
challenging in mobile environments.
It is important, however, to note that
these are not necessarily weaknesses
in ICN. Instead, they are exciting topics deserving future attention. Such
promising research has already begun
to develop, however, it is evident the diversity of mobile content access means
that any one-size-fits-all approach will
fall short. Consequently, we believe the
key future research challenge is building flexible general-purpose architectures that can handle all the situations
discussed within this article.

Practical challenges. A further challenge that perhaps exceeds all others is
the question of practical deployment.
Clearly, the discussed benefits can only
be gained if a node connects to (and
moves between) domains that support
ICN. Unfortunately, however, in practice, it is likely that any near-future ICN
deployments will be incremental overlay structures, making it impossible
to quantify the effectiveness of mobility support without concrete details of
The existence of islands of ICNs
connected via tunnels, for instance,
could severely damage mobility support if nodes were required to ‘dial-in’
via VPN-like services after every hand-off. Even low-delay access services
within the domain of the node might
create unacceptable delays if complex
authentication were required. Interestingly, this problem becomes even
more challenging when considering
the diversity of ICN proposals, likely
leading to the need for complicated
Despite this, clearly, the long-term
goal of ICN would be to move toward a
native deployment (for example, dual
stack). This would, of course, be an incremental process in which the benefits increase with each new domain’s
uptake (as with IPv6 deployment16).
However, an intelligent deployment
strategy could help mitigate any potential problems. Specifically, using the
lessons learned from previous overlay
technologies, many problems could be
avoided by integrating underlay knowledge (for example, locality awareness24). This still does, however, leave
open practical questions such as how
nodes might discover and connect to
ICN-enabled domains, including various autoconfiguration challenges.
This article has explored the world of
ICN, looking at how a shift from host-
centric to information-centric design
principles could support greater mobil-
ity in the future Internet. Clearly, this is
a hugely important topic, as we observe
more traffic being generated by mobile
hosts. 2 However, despite the clear po-
tential of ICN, a number of challenges
remain. Of particular importance is the
