                   Transport layer protocols over UDP 
                  draft-herbert-transports-over-udp-00

Abstract

   This specification defines a mechanism to encapsulate layer four
   transport protocols over UDP. Such encapsulation facilitates
   deployment of alternate transport protocols or transport protocol
   features on the Internet. DTLS can be employed to encrypt the
   encapsulated transport header in a packet thus minimizing the
   exposure of transport layer information to the network and so
   promoting the end-to-end networking principle.
