Atsra: An Accelerated Transmission Strategy Based On Request Aggregation In Ndn

Named Data Networking (NDN) is a novel network architecture which advocates data-centric paradigm for content distribution. Request aggregation is one of the key designs in NDN which can reduce overall traffic and speed up data delivery. However, request aggregation brings challenges for transport protocol design which affects the quality of experience (QoE) of users, as one request message(1) may correspond to multiple consumers'(2) requests. We propose an accelerated transmission strategy called ATSRA, which exploits the collaboration of the consumer and the access router(3) to adjust the request sending rate, to accelerate the content retrieval. ATSRA is a lightweight and flexible design. Simulation results show that ATSRA can achieve more efficient content retrieval and good users' QoE.
