A major role of today's Internet is to provide efficient content dissemination among users, such as distributing multimedia content and sharing user generated data. To meet the ever increasing demands, the Internet has been rapidly growing, and it now includes a web of tens of millions of networked devices ranging from content servers to core and edge(More)
Content-Centric Networking (CCN) and Service-Centric Networking(SCN) are two novel paradigms that seek to change the way content and services are perceived. CCN is centered around content distribution, while SCN focuses on dynamic customization of in-network services. We present SoCCeR--Services over Content-Centric Routing. SoCCeR extends CCN with(More)
Content-centric networking is a novel paradigm for the Future Internet that treats content as a first class citizen. This paper argues that content-centric networking should be generalized towards a service-centric networking scheme. We propose a service-centric networking design based on an object-oriented approach, in which content and services are(More)
Our energy efficiency analysis of various content dissemination strategies reveals that a change in network architecture from host-oriented to content-centric networking (CCN) can open new possibilities for energy-efficient content dissemination. In this paper, we consider energy-efficient CCN architecture and validate its energy efficiency via trace-based(More)
Host mobility has been a long standing challenge in the current Internet architecture. Huge proportions of traffic are now attributed to mobile devices [1]; however, despite this prominence, mobility often remains a badly handled concept. Some have recently argued that the main reason for this lies in its choice of what to name [2]. The Internet Protocol(More)
HTTP adaptive streaming (HAS) is quickly becoming a popular mechanism for delivering on-demand video content over the Internet. The chunked transmission and application-layer adaptation create a very different traffic pattern than traditional progressive video downloads where the entire video is downloaded with a single request. In this paper, we(More)
Swarm-based peer-to-peer streaming (SPS) mechanisms tend to generate a significant amount of costly inter-ISP traffic. Localization of overlay connectivity reduces inter-ISP traffic. However, it can adversely affect the delivered quality. In this paper, we systematically examine the performance of SPS for live video over localized overlays. We identify and(More)
One of the key questions in dimensioning a hybrid P2P content distribution system is that of the required infrastructure support in terms of server bandwidth. In this paper, we develop and propose simple mathematical models for analyzing and dimensioning hybrid peer-to-peer content distribution networks. We first use a deterministic fluid model to capture(More)
The proliferation of pictures and videos in the Internet is imposing heavy demands on mobile data networks. Though emerging wireless technologies will provide more bandwidth, the increase in demand will easily consume the additional capacity. To alleviate this problem, we explore the possibility of serving user requests from other mobile devices located(More)
Content-centric networking focuses on data delivery rather than end-to-end reachability by decoupling resources from the hosts they reside on. We consider content-centric networking as a fundamental driver for mobile ad hoc network (MANET) protocol design. We systematically evaluate the suitability and effectiveness of existing approaches toward designing a(More)
