Dear all,

Please find below our first updated version -01 of the MP-DCCP draft after WG adoption. I encourage you to review the diff at https://www.ietf.org/rfcdiff?difftype=--hwdiff&url2=draft-ietf-tsvwg-multipath-dccp-01.txt and join the draft development process at github. We plan to provide a next -02 version at the 6th of November, right before the IETF 112 meeting, finally incorporating all identified issues from
https://github.com/markusa/ietf-multipath-dccp/issues?q=is%3Aissue+label%3A-01%2C-02+is%3Aopen%2Cclosed

So far in -01 we made a lot of editorial changes, but also substantial ones.

- Define reliable exchange of multipath options https://github.com/markusa/ietf-multipath-dccp/pull/33
- Consistent description of multipath reordering https://github.com/markusa/ietf-multipath-dccp/pull/32
- Added a "Fallback" section describing strategies if Multipath fails https://github.com/markusa/ietf-multipath-dccp/pull/35
- Reduce number of author to be compliant with the RFC Editor Style guide https://www.rfc-editor.org/pipermail/rfc-interest/2015-May/008869.html
- Editorial: https://github.com/markusa/ietf-multipath-dccp/pull/37, https://github.com/markusa/ietf-multipath-dccp/pull/31, https://github.com/markusa/ietf-multipath-dccp/pull/17

Please provide us your comments here on the mailing list and if required in the Github issue tracker.

> Abstract:
>    DCCP communication is currently 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 DCCP to
>    support multipath operation.  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 flows across
>    potentially disjoint paths.
