Abstract

Abstract: Named-data networking (NDN) is designed to provide scalable and efficient content delivery, particularly for reducing redundant data transmission. To make the usefulness of NDN more widespread, however, it should support various types of traffic and their quality of Service (QoS) requirements. In this paper, we propose a differentiated services (diffserv) model for NDN. For scalability, the proposed diffserv model is designed to follow the guidelines from the diffserv model in the current Internet. Traffic classification and packet marking are performed at edge routers, and class-based service differentiation is provided by core routers. The proposed model is also considered to take the advantages of NDN unique features such as interest aggregation and in-network caching. We implement our model on the NDN module in ns3, and show the effectiveness of NDN diffserv through extensive simulations.
