Abstract: Caching and multipath forwarding are
essential ingredients of the Information-Centric Networking (ICN)
architecture resulting from ubiquitous content storage and content-based
node-by-node forwarding nature of ICN, much is yet to see how they
jointly act towards improving user's quality of experience. To this end,
we formulate in this paper a unified problem of caching and multipath
forwarding as a network optimization problem to maximize user
satisfaction which is expressed by their utility function. The
formulation allows us to see caching and multipath forwarding in ICN
from a congestion control perspective and to reinforce the advantage of a
class of congestion-aware caching where in-network caches are used to
absorb network congestion and to enhance user's satisfaction. In that
context, multipath forwarding plays the role of directing content
delivery to less congested paths where network capacity is abundant or
where requested content has been stored by in-network caches. We
evaluate such a congestion control-based, coupled caching and multipath
forwarding approach in simulations. The result confirms the advantage of
our approach compared with existing ones.
