23 | * @brief GNUnet CADET service with encryption | ||
24 | * @author Bartlomiej Polot | ||
25 | * | ||
26 | * FIXME in progress: | ||
27 | * - rekey - reliability interaction | ||
28 | * - channel retransmit timing | ||
29 | * | ||
30 | * TODO: | ||
31 | * - relay corking down to core | ||
32 | * - set ttl relative to path length | ||
33 | * TODO END | ||
34 | * | ||
35 | * Dictionary: | ||
36 | * - peer: other cadet instance. If there is direct connection it's a neighbor. | ||
37 | * - tunnel: encrypted connection to a peer, neighbor or not. | ||
38 | * - channel: connection between two clients, on the same or different peers. | ||
39 | * have properties like reliability. | ||
40 | * - path: series of directly connected peer from one peer to another. | ||
41 | * - connection: path which is being used in a tunnel. | ||
