Named Data Networking (NDN) has been recently proposed as a promising architecture for the Internet of the future where communications are centered around content rather than hosts. Despite its benefits, NDN brings several challenges like the design of novel data caching policies and efficient interest forwarding schemes (i.e., content look-up). In this paper, we survey the main NDN forwarding schemes proposed in the literature and classify them. We also conduct extensive simulations to evaluate and compare their performance in terms of throughput, mean download time, cache hit ratio and interest overhead. We finally discuss the simulation results and highlight the pros and cons of the existing strategies.
