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