Abstract:
   DCCP communications as defined in [RFC4340] are restricted to a
   single path per connection, yet multiple paths often exist between
   peers.  The simultaneous use of available multiple paths for a DCCP
   session could improve resource usage within the network and, thus,
   improve user experience through higher throughput and improved
   resilience to network failures.  Use cases for a Multipath DCCP (MP-
   DCCP) are mobile devices (e.g., handsets, vehicles) and residential
   home gateways simultaneously connected to distinct networks as, e.g.,
   a cellular and a Wireless Local Area (WLAN) networks or a cellular
   and a fixed access networks.  Compared to existing multipath
   protocols, such as MPTCP, MP-DCCP provides specific support for non-
   TCP user traffic (e.g., UDP or plain IP).  More details on potential
   use cases are provided in [website], [slide], and [paper].  All these
   use cases profit from an Open Source Linux reference implementation
   provided under [website].

   This document specifies a set of extensions to DCCP to support
   multipath operations.  Multipath DCCP provides the ability to
   simultaneously use multiple paths between peers.  The protocol offers
   the same type of service to applications as DCCP and it provides the
   components necessary to establish and use multiple DCCP subflows
   across different paths.
