Data Packet Classification for Implementing Cache Replacement Policies Based on Named Data Networks on the IDN Topology

There is an increase in internet users in the world from 3.9 - 5.3 billion in 2018–2023, based on the Cisco Annual Internet Report. However, TCP/IP as an internet protocol standard has shortcomings and will not be able to solve internet challenges in terms of data distribution due to the end-to-end nature of the network. In solving this challenge, a solution is offered using the Named Data Networking architecture with a distributed network paradigm and data communication using content names. The most crucial key in NDN is the caching strategy, such as the cache replacement policy. The goal of this research is to determine the effect of data packet classification on NDN architecture by testing Priority FIFO and LRU Caching Replacement Policy with the novelty of considering four classes of data packets at the producer side and changing their values at the content store. The test uses 26 nodes of the Indonesian Digital Network topology on Mini-NDN. Testing in this study uses 3 scenarios with different content store values, based on the test results, Priority-FIFO has 34% better performance than LRU based on the average RTT parameter, and based on the throughput value, Priority-FIFO performance also has 36% better performance than LRU.
