Dear all,

as part of the discussion on the transition from EXP to PS, we, the authors, have published -08 with a new section 3.9. This section describes the two path use strategies of mobility and concurrency and defines the components for the latter outside the scope of this document.

We are happy to continue the discussion based on this new version.

> 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].
