Thank you for your interest in this topic. As co-chair, I am trying to understand what kinds of additions you would be looking for to address metadata errors. All SF are already allowed to modify metadata. Any process for detecting and correcting erroneous metadata would seem on the one end to be permitted by current rules, and on the other hand to be highly specific to the precise metadata being dealt with. Did you have something more general, and needing documentation, to be added?

This draft is a work item of the Service Function Chaining WG of the IETF. Title : Active OAM for Service Function Chains in Networks Authors : Greg Mirsky Wei Meng Bhumip Khasnabish Cui Wang Filename : draft-ietf-sfc-multi-layer-oam-04.txt Pages : 18 Date : 2019-11-18 Abstract: A set of requirements for active Operation, Administration and Maintenance (OAM) of Service Function Chains (SFCs) in networks is presented. Based on these requirements an encapsulation of active OAM message in SFC and a mechanism to detect and localize defects described. Also, this document updates RFC 8300 in the definition of O (OAM) bit in the Network Service Header (NSH) and defines how the active OAM message identified in SFC NSH.

This draft is a work item of the Service Function Chaining WG of the IETF. Title : Proof of Transit Authors : Frank Brockners Shwetha Bhandari Tal Mizrahi Sashank Dara Stephen Youell Filename : draft-ietf-sfc-proof-of-transit-04.txt Pages : 29 Date : 2019-11-20 Abstract: Several technologies such as Traffic Engineering (TE), Service Function Chaining (SFC), and policy based routing are used to steer traffic through a specific, user-defined path. This document defines mechanisms to securely prove that traffic transited said defined path. These mechanisms allow to securely verify whether, within a given path, all packets traversed all the nodes that they are supposed to visit. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-sfc-proof-of-transit/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-sfc-proof-of-transit-04 https://datatracker.ietf.org/doc/html/draft-ietf-sfc-proof-of-transit-04 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-sfc-proof-of-transit-04 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.

Hi,

A comment regarding the Timestamp f= ormat that is defined in Section 5.2.
The Timestamp format should= be defined carefully. Please take a look at "Guidelines for Defining = Packet Timestamps" (draft-ietf-ntp-packet-timestamps).
I rec= ommend to use the template - Section 3 of draft-ietf-ntp-packet-timestamps.= The examples in the draft are pretty helpful.

Che= ers,
Tal.

Hi all,

I'm pleased to share this updated version of this spec. This version in= tegrates a detailed review and inputs from Dan.

FWIW, the main changes are as follows:
* SFFs are not supplied by design with the encryption material
* Motivate why base and service headers are not encrypted
* The inner packet is also integrity protected
* Use of timestamp to protect against replay attacks
* Restructure the design overview section to better highlight the provided = security protection services, which elements are involved, etc.
* Add a new section to discuss key management considerations
* Add a new section to discuss NSH-in-NSH
* Add more details to the processing rules
* And many edits.

Comments, question, and suggestions are more than welcome.

Cheers,
Med
