Transport Control Strategies in Named Data Networking: A Survey

Abstract

Different from traditional IP networks, named data networking (NDN) based on the named content can realize fast content retrieval and delivery. As one of the most important architectures for the future Internet, NDN needs flexible, effective, and efficient transport control strategies, which are crucial for widely development of NDN. In this paper, we present a comprehensive survey and research challenges on transport control of NDN for the first of time. We first provide an introduction of NDN and its data transport process. Then, the essential differences of NDN transport control compared with IP transport control are analyzed and compared from three perspectives: users side, routers, and network provider. Next, an in-depth taxonomy and classification of NDN recent transport control proposals is given. Finally, we present some research challenges and broader perspectives.
