4 * The secure anycast tunneling protocol (satp) defines a protocol used
5 * for communication between any combination of unicast and anycast
6 * tunnel endpoints. It has less protocol overhead than IPSec in Tunnel
7 * mode and allows tunneling of every ETHER TYPE protocol (e.g.
8 * ethernet, ip, arp ...). satp directly includes cryptography and
9 * message authentication based on the methodes used by SRTP. It is
10 * intended to deliver a generic, scaleable and secure solution for
11 * tunneling and relaying of packets of any protocol.
