Abstract
Today, the internet requires many additional mechanisms or protocols to support various ever-growing applications. As a future internet architecture candidate, the Named Data Network (NDN) offers a solution that naturally fulfills this need. One of the critical components in NDN is cache. Caching in NDN solves bandwidth usage, server load, and service time. Some research about caching has been conducted, but improvements can be made. In this research, we derived the utility function of multiclass content to obtain the relationship between the class’s weight and cache hit ratio. Then, we formulated it into the Weighted-CAPIC caching algorithm. Our research shows that Weighted-CAPIC provides a higher cache hit ratio for the priority class and the whole system. This performance is supported while the algorithm still provides the same path-stretch value as Dynamic-CAPIC. The Weighted-CAPIC is suitable to used in mobile nodes due to its ability to work individually without having to coordinate with other nodes.

Traffic in Named Data Network.Global internet traffic continues to increase every year
We propose Weighted-Cache based on Popularity and Class (Weighted-CAPIC) as a solution to provide a proper performance for priority class
In this research, we propose a Weighted Cache based on Popularity and Class (WeightedCAPIC) to improve the performance of the main priority class and the whole system in the mobile environment
Summary
The current internet uses TCP/IP, a host-based network In this architecture, consumer requests are addressed to a specific server address. NDN is ready for a consumer character with dynamic demand Another advantage is that we can treat traffic classes differently to give higher performance to the higher-priority classes based on the caching rules. Yovita et al proposed Dynamic-CAPIC, a caching algorithm that distinguishes the cache portion based on the popularity and class of the content in real-time [9] This algorithm increases the network cache hit ratio (CHR) and provides performance that matches a particular class on the system. Named Data Network (NDN) is one of the candidates for future internet architecture because it offers a more efficient communication mechanism than the current internet (TCP/IP). It is essential to regulate the mechanism in the content store to obtain optimal performance
