Precedence: list

Hi Folks,
As the new services develops, there proposed several encapsulations related with SFC, In-situ OAM, etc.
These services are tried to define independent headers. But in the scenario of IPv6, especially when SRH
is introduced for SRv6, such encapsulations faces some challenges. The draft, draft-li-6man-ipv6-sfc-ifit-00,
tries to identify the possible problems and proposes the consideration on how to optimize these encapsulations
in the scenarios of IPv6/SRv6 which includes:
1. Separate the SFC/IFIT path service into two parts, i.e. instruction and recording parts.
2. Defines the unified options as path service instruction which can be used in both Hop-by-Hop options Header
and SRH.
3. Defines the independent metadata header for IPv6 to record metadata info for services.

SFC WG and IPPM WG are copied.

Comments and suggestions are very welcome!

Best Regards,
Zhenbin (Robin)

主题: New Version Notification for draft-li-6man-ipv6-sfc-ifit-00.txt

A new version of I-D, draft-li-6man-ipv6-sfc-ifit-00.txt
has been successfully submitted by Zhenbin Li and posted to the
IETF repository.

Name: draft-li-6man-ipv6-sfc-ifit
Revision: 00
Title: Consideration of IPv6 Encapsulation for SFC and IFIT
Document date: 2019-03-11
Group: Individual Submission
Pages: 9
URL: https://www.ietf.org/internet-drafts/draft-li-6man-ipv6-sfc-ifit-00.txt

Abstract:
Service Function Chaining (SFC) and In-situ Flow Information
Telemetry (IFIT) are important path services along with the packets.
In order to support these services, several encapsulations have been
defined. The document analyzes the problems of these encapsulations
in the IPv6 scenario and proposes the possible optimized
encapsulation for IPv6.

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.
