#
# 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 methods used by SRTP. It is
# intended to deliver a generic, scaleable and secure solution for
# tunneling and relaying of packets of any protocol.
