+# NDN Forwarding Plane
 
 NDN uses a stateful forwarding plane[@cc2013stateful] that maintains several tables at forwarders. This is in contrast to the stateless forwarding plane of IP, which does not maintain any per-packet state. The stateful forwarding plane of NDN enables Data multicast and caching, along with other features such as privacy, loop detection, network-layer congestion control[@icn2019congestion] and DoS protection[@icccn2013ddos].

 !!! tip "Connecting NFD to the Testbed"
     To connect your local NFD to the testbed, use the `ndn-autoconfig` tool. This tool uses the Find-Closest-Hub (FCH) service to find the closest testbed node, and creates a face from your local NFD to that node. It also configures the local NFD to use the testbed as a default route for Interests that do not match any local routes.

+# Introduction to Named Data Networking
 
 Named Data Networking (NDN)[@sigcomm2014ndn] is a future Internet architecture inspired by years of research into network usage and a growing awareness of unsolved problems in the contemporary protocols. Many of these problems arise due to the fundamental mismatch between the data-centric usage of the Internet and the host-centric nature of IP. NDN is designed as a data-centric replacement of the TCP/IP architecture, thus overcoming this mismatch by replacing the network layer itself. The NDN project is now a collaborative effort of a large community of researchers at more than a dozen institutions.
