Cloud Terminal Access and QoS Enhancement by Content Store and Service Load Classification in Named Data Network

As one of the most popular topics in the Next Generation Network (NGN), Named Data Networking (NDN), a newly proposed network architecture centered on content data, targets on altering the existing communication protocol between Internet hosts. NDN uses data names rather than IP addresses for data transmission and re-designs the packet formats and the protocols between layers in order to substitute the conventional IP architecture. Quality of Service (QoS) in conventional IP network aims at bandwidth optimization in limited bandwidth network environments and bandwidth guarantees for specific applications, or user satisfaction of specific needs. To break away from traditional QoS, the next service-stack network attempts to reduce the total throughput and avoid data retransmissions over the network. Traditional QoS solutions are effective in IP networks but do not fit the needs of the NDN. Therefore, this paper defines the QoS parameters and measurements and also their impact on the NDN network performance.
