Effect of the Content Store Size to the Performance of Named Data Networking: Case Study on Palapa Ring Topology Muhammad Najib Dwi Satria 1 , Sigit Haryadi 2 School of Electrical Engineering and Informatics, Institut Teknologi Bandung, Indonesia muhammadnajibds@gmail.com 1 , sigitharyadi59@gmail.com 2 Abstract — in the digital era of information technology today, information technology services are needed by all parties ranging from lay people, educational organizations, government organizations, and companies. The current digital growth has resulted in data information services being used as a distribution network that is essentially more common than communication networks and solving distribution problems of complex point-to-point communication protocols and error-prone. One of them is Named Data Networking (NDN), which is a future network technology that is present in helping the effectiveness of network usage in contemporary Internet architecture such as Internet Protocol (IP). With the development of telecommunication technology in Indonesia, through the Ministry of Communication and Information has issued a project Palapa Ring backbone network which is one of the concerns of the Government of the Republic of Indonesia to build the availability of fiber-optic network as the backbone of the national telecommunication network that connects all regions in Indonesia. In this paper will discuss how the effect of changing the size of the content store in the NDN networks using the topology Palapa ring by measuring some parameters such as the value of the dropped package or the value of a delay package. Keywords—Named Data Networking, IP, Palapa Ring, Content Store I. INTRODUCTION The current growth of digital age have resulted in data information services being used as a distribution network that is essentially more common than communication networks and solving distribution problems of complex point-to- point communication protocols and error-prone. One of them is Named Data Networking (NDN) which is a future network technology that is present at this time in helping the effectiveness of network usage on contemporary internet architecture like Internet Protocol (IP). Named data network is rooted in the previous technology, Content-Centric Networking (CCN), first published by Van Jacobson in 2006. The NDN itself evolves from a host-centric IP network architecture developed into a data-centric network architecture. The belief is that with this simple conceptual shift will have broad implications for how people design, develop, deploy, and also use networks and applications. NDN is a network architecture based on the name of the content that allows the creation of a public distribution network. This technology is one of our basic studies to see the effect of the size of an existing content store on the NDN network [1]. These changes also pose significant new challenges by using names on data delivery and not only bring the great benefits mentioned above, but also bring new design opportunities as well as some new problems. Because Named Data Network (NDN) changes the changes in the request and the process of calling data onto the internet protocol address of a name. And it becomes a question of how applications should choose the content of data names to facilitate both application and network development in data delivery.
