22 * @file mesh/gnunet-service-mesh.c
23 * @brief GNUnet MESH service with encryption
24 * @author Bartlomiej Polot
27 * - rekey - reliability interaction
28 * - channel retransmit timing
31 * - relay corking down to core
32 * - set ttl relative to path length
36 * - peer: other mesh 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.
