+ <dt>Applications</dt>
+ <dd>
+ Applications are components which directly use the DHT overlay
+ interfaces. Possible applications include the GNU Name System
+ <xref target="I-D.draft-schanzen-gns" /> or the CADET transport system
+ <xref target="cadet" />.
+ </dd>
+ <dt>Overlay Interface</dt>
+ <dd>
+ The Overlay Interface exposes the core operations of the DHT overlay
+ to applications.
+ This includes querying and retrieving data from the DHT.
+ </dd>
+ <dt>Block Storage</dt>
+ <dd>
+ The Block Storage component is used to persist and manage data
+ by peers. It includes logic for quotas, caching stragegies and
+ data validation.
+ </dd>
+ <dt>Message Processing</dt>
+ <dd>
+ The Message Processing component processes requests from and responses
+ to applications as well as messages from the underlay network.
+ </dd>
+ <dt>Routing</dt>
+ <dd>
+ The Routing component includes the routing table as well as
+ routing and peer selection logic. It facilitates the R5N routing
+ algorithm with required data structures and algorithms.
+ </dd>
+ <dt>Underlay Interface</dt>
+ <dd>
+ The DHT Underlay Interface is an abstraction layer on top of the
+ supported links of a peer. Peers may be linked by a variety of
+ different transports, including "classical" protocols such as
+ TCP, UDP and TLS or advanced protocols such as GNUnet, L2P or Tor.
