Information Centric Networks

Since its inception, the Internet has evolved from a textualinformation system towards a multimedia information system, inwhich data, services and applications are consumed as content. Today, however, the main problem faced is that applications are nowcontent-oriented but the protocol stack remains the same, based onthe content location. Thus, it is clear that the Internet'scurrent architecture must change. This new architecture should takeinto account aspects to improve content location and deliveryefficiency and also content availability. Fulfilling theserequirements is the main goal of information-centric networks(ICNs).
ICN is a new communication paradigm to increase the efficiency ofcontent delivery and also content availability. In this newconcept, the network infrastructure actively contributes to contentcaching and distribution. This book presents the basic concepts ofICNs, describes the main architecture proposals for these networks, and discusses the main challenges to their development. InformationCentric-Networks looks at the current challenges for this concept, including: naming, routing and caching on the network-coreelements, several aspects of content security, user privacy, andpractical issues in implementing ICNs.
