Centralized Controller Implementation In Named Data Network (NDN)

Named Data Networking (NDN) is a future Internet network architecture design under development, which changes the host-centric to the content-centric network model. Researchers have developed NDN-based networks in recent years in an attempt to overcome the limitations of the TCP/IP architecture. Named data networks using content names involve many things, including routing. Although NDN has a routing protocol, the current problem is that it has high overhead because the routing used by NDN is currently decentralized, where each synchronization and path update process uses broadcast packet delivery. To reduce broadcasts and reduce the overhead of creating a controller where the controller has a separate signaling path from the data path. How to combine NDN with centralized control and design the overall architecture to achieve good performance and overhead has been done by many previous researchers. However, the development process still relies heavily on IP. So in this paper, we propose an NDN Centralized Routing that runs on top of NDN. It only forwards packets of named packets by eliminating the IP of routers to communicate. This paper also compares the Centralized Routing system and the Decentralized Routing system. As a result, the overhead generated by centralized routing is lower when compared to decentralized routing.
