23 * @brief GNUnet MESH service with encryption
24 * @author Bartlomiej Polot
27 * - when sending in-order buffered data, wait for client ACKs
30 * - set connection IDs independently from tunnel, tunnel has no ID
33 * - relay corking down to core
34 * - set ttl relative to path length
38 * - peer: other mesh instance. If there is direct connection it's a neighbor.
39 * - tunnel: encrypted connection to a peer, neighbor or not.
40 * - channel: connection between two clients, on the same or different peers.
41 * have properties like reliability.
42 * - path: series of directly connected peer from one peer to another.
43 * - connection: path which is being used in a tunnel.
