- * anytun
- *
- * 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.
