[tcpm] Inner Option Space revised: inner-space-01

[Bob Briscoe <[e-mail]>]

TCPM folks,

I've posted a revision to:
"Inner Space for TCP Options"
<https://tools.ietf.org/html/draft-briscoe-tcpm-inner-space-01>

Thanks to the following for useful discussions (mostly off-list), 
whom I've added the Acknowledgements section:
Costin Raiciu, Marcelo Bagnulo Braun, Julian Chesterfield and Jaime 
Garcia, and of course the continuing discussions with Joe Touch.

       Technical changes:

       *  Corrected DO to 4 * DO (twice)
       *  Confirmed that receive window applies to Inner Options
       *  Generalised the cause of decryption/decompression from a
          previous TCP option to any previous control message
       *  Added requirement for a middlebox not to defer data on SYN
       *  Latency of dual handshake is worst of two
       *  Completed "Interaction with Pre-Existing TCP Implementations"
          section, covering other TCP variants, TCP in middleboxes and
          the TCP API.  Shifted some TCP options to Outer only, because
          of RWND deadlock problem
       *  Added two outstanding issues: i) ossifies reliable ordered
          delivery; ii) Ideally Outer in Inner.

       Editorial changes:

       *  Removed section on Echo TCP option to a separate I-D that is
          mandatory to implement for inner-space, and shifted some SYN
          flood discussion in Security Considerations
       *  Clarifications throughout
       *  Acknowledged more review comments

Cheers


Bob

>Abstract:
>    This document describes an experimental method to extend the limited
>    space for control options in every segment of a TCP connection.  It
>    can use a dual handshake so that, from the very first SYN segment,
>    extra option space can immediately start to be used optimistically.
>    At the same time a dual handshake prevents a legacy server from
>    getting confused and sending the control options to the application
>    as user-data.  The dual handshake is only one strategy - a single
>    handshake will usually suffice once deployment has got started.  The
>    protocol is designed to traverse most known middleboxes including
>    connection splitters, because it sits wholly within the TCP Data.  It
>    also provides reliable ordered delivery for control options.
>    Therefore, it should allow new TCP options to be introduced i) with
>    minimal middlebox traversal problems; ii) with incremental deployment
>    from legacy servers; iii) without an extra round of handshaking delay
>    iv) without having to provide its own loss recovery and ordering
>    mechanism and v) without arbitrary limits on available space.
