In CCN (Content-Centric Networking), one request retrieves at most one data packet. Although the design intent of such rule is to maintain flow balance across the network, it may cause significant underutilization of Data downlink, especially in networks with asymmetric up/down link speed such as cellular networks. This paper describes an adaptive flow control mechanism where multiple Data messages per Interest are allowed in an adaptive manner without violating the operational principle of original CCN protocol. The performance of proposed scheme is demonstrated in an experimental testbed implementation built with CCNx open source code and its extension.
While the majority of Internet traffic is becoming of high quality multimedia variety, also mostly generated by consumers themselves, efficient content sharing with intuitive useability and security measure in a mobile environment remains an elusive goal. In this paper, we present a Content-Centric Networking (CCN) based Virtual Private Community (VPC) service which aims at supporting intuitive content sharing experience in a secure and distributed manner. VPC is a hierarchical and closed user group which consumers themselves can easily create and manage on their own devices. In VPC architecture, consumer content is shared by VPC-based content forwarding policy which is also based on hierarchical content naming. We prototyped the VPC architecture on the consumer devices to demonstrate the potential of user-oriented and distributed consumer network platform.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
