Information-Centric Networks (PDF)

Since its inception, the Internet has evolved from a textual
information system towards a multimedia information system, in
which data, services and applications are consumed as content.
Today, however, the main problem faced is that applications are now
content-oriented but the protocol stack remains the same, based on
the content location. Thus, it is clear that the Internet's
current architecture must change. This new architecture should take
into account aspects to improve content location and delivery
efficiency and also content availability. Fulfilling these
requirements is the main goal of information-centric networks
(ICNs).

ICN is a new communication paradigm to increase the efficiency of
content delivery and also content availability. In this new
concept, the network infrastructure actively contributes to content
caching and distribution. This book presents the basic concepts of
ICNs, describes the main architecture proposals for these networks,
and discusses the main challenges to their development. Information
Centric-Networks looks at the current challenges for this concept,
including: naming, routing and caching on the network-core
elements, several aspects of content security, user privacy, and
practical issues in implementing ICNs.
