It includes a short section on monitoring service functions. Unless I misread that, the description could be enhanced by noting that another measurement method would be to monitor traffic on both sides of the SF (at the relevant SFF, and perform suitable correlation.

The initial Conventions and Terminology section assumes the reader is famil= iar with RFC7665, as usual. Nevertheless, to strengthen the description of = the motivating use cases, I would consider recapping some key terms (e.g., = SFF, SFC-aware SFs, SFC Proxy, SFC Encapsulation) and have them appear in the use case description, which curr= ently focuses on the problem but could provide a further technical glimpse = on potential solutions unlocked through the proposed Identifiers {Subscribe= r, Slice and Service}. It would help to read in each use case a concrete ex= ample of a specific network element performing SFC Encapsulation and includ= ing one of the proposed Identifiers later used by other specific elements i= n the SFC. In the context of the NECOS project [1], we have identified some network sl= icing scenarios [2] that I believe could be nicely realized with SFC featur= ing the proposed Slice Identifiers, offering a candidate realization strate= gy for some slicing modes of operation to which we do not have an actual te= chnical solution yet. Maybe we can propose a specific scenario description = for another sample use case 3.X. to be included in a future revision of the= draft. I am copying some project colleagues who may also be interested in = the SFC Slice Identifiers. In addition to the suggestions above, in the attached file you can find fur= ther comments marked with [DANNY].

This draft is a work item of the Service Function Chaining WG of the IETF. Title : Service Function Chaining: Subscriber and Service Identification Use Cases and Variable-Length NSH Context Headers Authors : Behcet Sarikaya Mohamed Boucadair Dirk von Hugo Filename : draft-sarikaya-sfc-hostid-serviceheader-07.txt Pages : 15 Date : 2018-06-21 Abstract: This document discusses how to inform Service Functions about service- and subscriber-related information for the sake of policy enforcement and appropriate SFC-inferred forwarding. Once the information is consumed by SFC-aware elements of an SFC-enabled domain, it is stripped from packets when they leave the SFC-enabled domain. Thus privacy-sensitive information is not leaked outside the domain.

RFC 8459 Title: Hierarchical Service Function Chaining (hSFC) Author: D. Dolson, S. Homma, D. Lopez, M. Boucadair Status: Experimental Stream: IETF Date: September 2018 Mailbox: ddolson@acm.org, homma.shunsuke@lab.ntt.co.jp, diego.r.lopez@telefonica.com, mohamed.boucadair@orange.com Pages: 29 Characters: 58590 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-sfc-hierarchical-11.txt URL: https://www.rfc-editor.org/info/rfc8459 DOI: 10.17487/RFC8459 Hierarchical Service Function Chaining (hSFC) is a network architecture allowing an organization to decompose a large-scale network into multiple domains of administration. The goals of hSFC are to make a large-scale network easier to design, simpler to control, and supportive of independent functional groups within large network operators.

not support iOAM at all or the particular mode? I believe that the most likely, the packet will be dropped by the SFF, i.e., the original data packet will be dropped because some upstream SFF inserted iOAM data in it. Is that acceptable behavior? Of course, to avoid loss of data resulted from the some SFF non-support of iOAM the WG can add the requirement that to use iOAM all elements of the SFP MUST support iOAM.

A new section with the description of the Compact Marking method explains how one bit-size mark can be used to enable high accuracy measurement of delay and packet loss. And thus we've updated the proposal to allocate the Mark field in SFC NSH from two-bits to one-bit field. Much appreciate your comments, questions. Authors believe that the draft is ready for the WG adoption call and ask the WG Chairs for consideration.
