* 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.
