A reality check for content centric networking

Abstract

Content-Centric Networking (CCN) is a novel networking paradigm centered around content distribution rather than host-to-host connectivity. This change from host-centric to content-centric has several attractive advantages, such as network load reduction, low dissemination latency, and energy efficiency. However, it is unclear whether today's technology is ready for the CCN (r)evolution. The major contribution of this paper is a systematic evaluation of the suitability of existing software and hardware components in today's routers for the support of CCN. Our main conclusion is that a CCN deployment is feasible at a Content Distribution Network (CDN) and ISP scale, whereas today's technology is not yet ready to support an Internet scale deployment.

Understanding the social impact of ICN: between myth and reality

“…In literature several researchers have sorted out the requirements to design a content store for an ICN device [59]- [62]. Hereby the authors report the community's findings and a description of the open-issues to address.…”

“…As regards the second question, research works have so far converted traffic generated by used Internet applications taken out of official traces to generate credible ICN workload [65], [59]. As regards the last question, the most appropriate metric to consider while dimensioning the PIT has been so far the average Internet round-trip time [62].…”

Exploring the Next Generation Network Architecture based on SDN

“…Currently [12], there is a lack of killer applications for SDN and the good SDN solutions can't be offered to deal with the problems raised by the customer, especially the application with the characteristics of the industry is in urgent need. Moreover, SDN is a late-model of network architecture which is characterized by its openness will caused a certain security hidden danger, especially server for operating network system is likely to become the target of an attack.…”

A greedy ant colony forwarding algorithm for Named Data Networking

“…The main conclusion of their work is that a NDN deployment is feasible at a Content Distribution Network (CDN) and ISP scale, whereas today's technology is not yet ready to support an Internet scale deployment [2]. NDN shifts the address space from one billion IPs to at least one trillion content names [6], which causes a n eat increase of the routing state to be stored at content routers.…”
