Abstract:

   Datagram Congestion Control Protocol (DCCP) communications, as
   defined in RFC 4340, are inherently restricted to a single path per
   connection, despite the availability of multiple network paths
   between peers.  The ability to utilize multiple paths simultaneously
   for a DCCP session can enhance network resource utilization, improve
   throughput, and increase resilience to network failures, ultimately
   enhancing the user experience.

   Use cases for Multipath DCCP (MP-DCCP) include mobile devices (e.g.,
   handsets, vehicles) and residential home gateways that maintain
   simultaneous connections to distinct network types, such as cellular
   and Wireless Local Area Networks (WLANs) or cellular and fixed access
   networks.  Compared to existing multipath transport protocols, such
   as Multipath TCP (MPTCP), MP-DCCP is particularly suited for latency-
   sensitive applications with varying requirements for reliability and
   in-order delivery.

   This document specifies a set of protocol extensions to DCCP that
   enable multipath operations.  These extensions maintain the same
   service model as DCCP while introducing mechanisms to establish and
   utilize multiple concurrent DCCP flows across different network
   paths.
