Comparison of OpenWRT and Ubuntu for Named Data Networking

The Named Data Network (NDN) represents a promising candidate for the future of network architecture, particularly in light of its potential integration with caching and forwarding systems. Comparing Operation System (OS) in NDN which is important because each OS has a different way of managing resources such as CPU, memory, and network. The selection of OpenWRT and Ubuntu for comparison was based on the premise that OpenWRT is optimized for network devices, whereas Ubuntu is more commonly utilized for desktops, servers, and the cloud, thereby representing two distinct purposes. The Banana Pi BPI-R2 was selected as the platform of choice due to its capacity to accommodate more intricate network configurations.The scenario employed for comparison encompasses three variables: content store size, content size, and interest rate. The implementation results demonstrate that Ubuntu outperforms OpenWRT regarding RTT (round-trip time), exhibiting a $0.27 \%$ reduction in this metric. Furthermore, Ubuntu exhibited a $0.83 \%$ improvement in throughput and a $54.43 \%$ reduction in CPU usage compared to OpenWRT. Modifications to the content size resulted in superior performance by Ubuntu, with a reduced RTT by $\mathbf{1 1. 2 0 \%}$, a $\mathbf{4. 7 2 \%}$ higher throughput, and a $54.85 \%$ lower CPU usage compared to OpenWRT. Upon examination of the data, it became evident that when interest rates were altered, Ubuntu exhibited superior performance compared to OpenWRT. This was evidenced by a $\mathbf{1 6. 4 2 \%}$ reduction in RTT, a $\mathbf{1 6. 8 4 \%}$ increase in throughput, and a $\mathbf{6 6. 7 6 \%}$ decrease in CPU usage, all of which favoured Ubuntu.
