Description
Summary:Named Data Networking (NDN) architecture promises significant advantages over current Internet architecture by replacing its host-centric design with a content-centric one. In NDN, the mode that one Interest packet gets one Data packet can quite easily lead to Interest flooding and a huge number of the related entries. Moreover, the absence of predefined connections is a challenge for NDN to efficiently manage the successive requests from consumers or the innetwork concurrent requests. In this paper, we argue that it is necessary for NDN to support flow transmission mechanism aimed at improving transmission performance, and based on it we design flow-based NDN (f-NDN) architecture which can not only achieve overload decreasing by packing successive Interest packets but also performance improvement and load-balance by multi-path. Simulation of our architecture is carried out in different network scenarios to evaluate the performance of our architecture. Evaluation results show that the proposed architecture operates better than NDN architecture in many aspects such as transmission efficiency and system load including reducing the number of Interest packets and lookup operations performed on the related tables in routers.
