Fwd: New Version Notification for draft-liu-multipath-quic-01.txt

[Yanmei Liu <[e-mail]>]

Hi all, 

Here is an updated version of the draft which was posted in the mailing list last Friday. Please check this link: https://tools.ietf.org/html/draft-liu-multipath-quic-01
Regarding the questions in the mailing list for the previous version:
1. We have fixed the IANA registry problem in the new version. Thanks Lucas for pointing out this problem.
2. We currently use Github for editing, and we prefer discussions on the mailing list, so we removed the Github link in this draft. 

This version merges our draft and Christian’s draft, and here are some of the key features:

 * Re-use as much as possible mechanisms of QUIC-v1, which has
 supported connection migration and path validation.

 * To avoid the risk of packets being dropped by middleboxes (which
 may only support QUIC-v1), use the same packet header formats as
 QUIC V1.

 * Endpoints need a Path Identifier for each different path which is
 used to track states of packets. As we want to keep the packet
 header formats unchanged [QUIC-TRANSPORT], Connection IDs (and the
 sequence number of Connection IDs) would be a good choice of Path
 Identifier.

 * For the convenience of packet loss detection and recovery,
 endpoints use a different packet number space for each Path
 Identifier.

 * Congestion Control, RTT measurements and PMTU discovery should be
 per-path (following [QUIC-TRANSPORT])

Thanks Jana and Kazuho for reviewing the proposal.

We would like to know how people think about the draft, and all feedbacks and suggestions are welcome!


Thanks, 
Yanmei

has been successfully submitted by Yanmei Liu and posted to the
IETF repository.

Name:  draft-liu-multipath-quic
Revision: 01
Title:  Multipath Extension for QUIC

Abstract:
   This document specifies multipath extension for the QUIC protocol to
   enable the simultaneous usage of multiple paths for a single
   connection.  The extension is compliant with the single-path QUIC
   design.  The design principle is to support multipath by adding
   limited extension to [QUIC-TRANSPORT].




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
