[tsvwg] FW: I-D Action: draft-ietf-tsvwg-multipath-dccp-06.txt

[[e-mail]]

Dear all,

After a thorough review by Med, we have published version -06 with many changes in readability, consistency, clarity, and formalism related to following
PRs https://github.com/markusa/ietf-multipath-dccp/pulls?q=is%3Apr+author%3Aboucadair 
and
Issues https://github.com/markusa/ietf-multipath-dccp/issues?q=is%3Aissue+author%3Aboucadair

Aside from these many adjustments, it is worth noting that the draft now defines a MP-DCCP sub-option for experimental use and a much more robust section on IANA Considerations.

Thank you, Med, for this great review and your willingness to discuss in detail the authors' resulting proposals.
And thank you Behcet for confirming on the mailing list that from your point of view there is no ambiguity left after all the changes for -06.

The comprehensive list of changes is available at https://github.com/markusa/ietf-multipath-dccp/releases/tag/draft-ietf-06

> 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].
> 
>    This document specifies a set of extensions to DCCP to support
>    multipath operations.  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 subflows
>    across different paths.
