Abstract:
   More and more of today's devices are multi-homing capable, in
   particular 3GPP user equipment like smartphones.  In the current
   standardization of the next upcoming mobile network generation 5G
   Rel. 16, this is especially targeted in the study group Access
   Traffic Steering Switching Splitting [3GPP, TR 23.793].  ATSSS
   describes the flexible selection or combination of 3GPP untrusted
   access like Wi-Fi and cellular access, overcoming the single-access
   limitation of today's devices and services.  Another multi-
   connectivity scenario is the Hybrid Access [draft-lhwxz-hybrid-
   access-network-architecture, draft-muley-network-based-bonding-
   hybrid-access], providing multiple access for CPEs, which extends the
   traditional way of single access connectivity at home to dual-
   connectivity over 3GPP and fixed access.  A missing piece in the
   ATSSS and Hybrid Access is the access and path measurement for
   efficient and beneficial traffic steering decisions.  This becomes
   particularly important in heterogeneous access networks with a
   multitude of volatile access paths.  MP-TCP can be employed in such
   scenarios and concerning the ATSSS, it is the agreed protocol for the
   traffic splitting mode.  A decision for MP-TCP though leaves the
   increasing share of UDP in today's traffic mix (https://arxiv.org/
   abs/1801.05168) unconsidered.  In this document, a network
   architecture leveraging the MP-DCCP network protocol is proposed,
   which enables above scenarios and address the formulated issues
   either independent or complementary to MP-TCP.
