Global traffic data are proliferating, including in Indonesia. The number of internet users in Indonesia reached 205 million in January 2022. This data means that 73.7% of Indonesia’s population has used the internet. The median internet speed for mobile phones in Indonesia is 15.82 Mbps, while the median internet connection speed for Wi-Fi in Indonesia is 20.13 Mbps. As predicted by many, real-time traffic such as multimedia streaming dominates more than 79% of traffic on the internet network. This condition will be a severe challenge for the internet network, which is required to improve the Quality of Experience (QoE) for user mobility, such as reducing delay, data loss, and network costs. However, IP-based networks are no longer efficient at managing traffic. Named Data Network (NDN) is a promising technology for building an agile communication model that reduces delays through a distributed and adaptive name-based data delivery approach. NDN replaces the ‘where’ paradigm with the concept of ‘what’. User requests are no longer directed to a specific IP address but to specific content. This paradigm causes responses to content requests to be served by a specific server and can also be served by the closest device to the requested data. NDN router has CS to cache the data, significantly reducing delays and improving the internet network’s quality of Service (QoS). Motivated by this, in 2019, we began intensive research to achieve a national flagship product, an NDN router with different functions from ordinary IP routers. NDN routers have cache, forwarding, and routing functions that affect data security on name-based networks. Designing scalable NDN routers is a new challenge as NDN requires fast hierarchical name-based lookups, perpackage data field state updates, and large-scale forward tables. We have a research team that has conducted NDN research through simulation, emulation, and testbed approaches using virtual machines to get the best NDN router design before building a prototype. Research results from 2019 show that the performance of NDN-based networks is better than existing IP-based networks. The tests were carried out based on various scenarios on the Indonesian network topology using NDNsimulator, MATLAB, Mininet-NDN, and testbed using virtual machines. Various network performance parameters, such as delay, throughput, packet loss, resource utilization, header overhead, packet transmission, round trip time, and cache hit ratio, showed the best results compared to IP-based networks. In addition, NDN Testbed based on open source is free, and the flexibility of creating topology has also been successfully carried out. This testbed includes all the functions needed to run an NDN network. The resource capacity on the server used for this testbed is sufficient to run a reasonably complex topology. However, bugs are still found on the testbed, and some features still need improvement. The following exploration of the NDN testbed will run with more new strategy algorithms and add Artificial Intelligence (AI) to the NDN function. Using AI in cache and forwarding strategies can make the system more intelligent and precise in making decisions according to network conditions. It will be a step toward developing NDN router products by the Bandung Institute of Technology (ITB) Indonesia.
