Caching Strategies in NDN Networks

Faced with the limitations of traditional Internet architecture, Information Centric Networks (ICN) have emerged as a promising alternative for the future of the Internet. Their main advantage lies in the native integration of network caching, a mechanism whose efficiency is crucial to the overall performance of the architecture.At the heart of this efficiency lies the caching strategy, whose role is to manage content and decide on its optimal placement within the network. The major challenge for these strategies is the strategic selection of cache routers along the delivery path. Solving this problem reduces network congestion, optimizes the distance between consumers and data, improves latency and relieves the load on the original servers.
