             Multipath Message Transport Protocol Based on 
                   Application-level Relay (MPMTP-AR)

Abstract

   Multipath transmission is regarded as an effective way to improve the
   quality of service of data delivery. This document defines a
   multipath message transport protocol based on application level relay
   (MPMTP-AR), which is a special profile of multipath transport
   protocol suite defined in Multipath Transport System Based on
   Application-level Relay (MPTS-AR). MPMTP-AR provides reliable data
   delivery service over multiple paths. This document discusses related
   message format and mechanism to support MPMTP-AR.
