4 * uAnytun is a tiny implementation of SATP. Unlike Anytun which is a full
5 * featured implementation uAnytun has no support for multiple connections
6 * or synchronisation. It is a small single threaded implementation intended
7 * to act as a client on small platforms.
8 * The secure anycast tunneling protocol (satp) defines a protocol used
9 * for communication between any combination of unicast and anycast
10 * tunnel endpoints. It has less protocol overhead than IPSec in Tunnel
11 * mode and allows tunneling of every ETHER TYPE protocol (e.g.
12 * ethernet, ip, arp ...). satp directly includes cryptography and
13 * message authentication based on the methods used by SRTP. It is
14 * intended to deliver a generic, scaleable and secure solution for
15 * tunneling and relaying of packets of any protocol.
