Table 1: Comparison TCP/IP and NDN technology. the specific needs and preferences of the user. Consumers indicate interest in data with particular specifications, and the network adjusts its supply to optimize accordingly. In contrast, NDN operates oppositely, as content is stored within the router, continuously eliminating the need to request content from a central server. Within NDN, mobility is categorized into two distinct forms: content consumer and producer mobility. This study emphasizes the advantages of an efficient NDN architecture by examining its uses in conventional and innovative contexts. The novel NDN technology optimizes performance by reducing cache ingestion and enhancing time consumption [4]. Furthermore, the NDN architecture enables the utilization of mechanisms not supported by traditional IP-addressing communication. The NDN architecture facilitates the retrieval of incomplete data, enables translucent failover, and allows for the restoration of consumer node content [5]. NDN has persistently advanced its affiliated protocols and explored several use cases for NDN applications, encompassing video streaming, online gaming, and social networking [6]. Moreover, several organizations and enterprises have also demonstrated interest in NDN and its possible applications. Cisco has expressed the view that NDN has the potential to offer answers to the most challenging networking issues currently being encountered [7]. In a scholarly publication in 2018, scholars affiliated with Huawei Technologies examined the potential of NDN in facilitating edge computing, with the researchers exploring how NDN may enhance the efficacy and security of data transfer within edge networks [8]. Consequently, NDN technology has garnered considerable attention within the computer industry, as it can mitigate some constraints associated with conventional IP-based networking. While still in its early stages and undergoing continuous development, this architectural approach has the potential to fundamentally reshape our understanding and methods of computer network design and implementation.
