Hi Markus, 

Apologies for the delay to share my review. 

FWIW, I submitted a set issues and PRs that you can track at: 

* https://github.com/markusa/ietf-multipath-dccp/issues/created_by/boucadair
* https://github.com/markusa/ietf-multipath-dccp/pulls/boucadair

Cheers,

> > Abstract:
> >    DCCP communication as defined in [RFC4340] is restricted to a
> single
> >    path per connection, yet multiple paths often exist between
> peers.
> >    The simultaneous use of these 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 (handsets, vehicles) and residential home
> gateways
> >    simultaneously connected to distinct paths as, e.g., a
> cellular link
> >    and a WiFi link or to a mobile radio station and a fixed
> access
> >    network.  Compared to existing multipath protocols such as
> MPTCP, MP-
> >    DCCP provides specific support for non-TCP user traffic as
> 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 presents a set of extensions to traditional
