From 6e739b09bef860a4830328630ea07622bdd79d79 Mon Sep 17 00:00:00 2001 From: dimitri staessens Date: Thu, 13 Jul 2017 09:43:09 +0200 Subject: ipcpd: Add DHT as directory in normal IPCP This implements a Distributed Hash Table (DHT) based on the Kademlia protocol, with default parameters set as used in the BitTorrent Mainline DHT. This initial implementation is almost feature complete, except for some things to be done after a testing period: caching and stale peer bumping, and setting the expiration timeout via the IRM tool. --- src/ipcpd/normal/dht.h | 54 ++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 54 insertions(+) create mode 100644 src/ipcpd/normal/dht.h (limited to 'src/ipcpd/normal/dht.h') diff --git a/src/ipcpd/normal/dht.h b/src/ipcpd/normal/dht.h new file mode 100644 index 00000000..5d7fc894 --- /dev/null +++ b/src/ipcpd/normal/dht.h @@ -0,0 +1,54 @@ +/* + * Ouroboros - Copyright (C) 2016 - 2017 + * + * Distributed Hash Table based on Kademlia + * + * Dimitri Staessens + * Sander Vrijders + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public License + * version 2.1 as published by the Free Software Foundation. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
