Dear all, if it’s still worth I did another quick review on the latest version and while I agree to move the document forward I want to point you to some nits or what I thought could be: p.2: 1. Service Function Path identification => 1. Service Function Path (SFP) identification p.3: and the interpretation of the Tenant ID field => and the interpretation of the Forwarding Context ID field See Figure Figure 3. Reserved => See Figure 3. Reserved Same with Figure 4/5/6 … p.6 or 8 bytes MAC address, etc,. => or 8 bytes MAC address (EUI-64), etc. Thanks! Best Regards Dirk From: sfc <sfc-bounces@ietf.org> On Behalf Of wei.yuehua@zte.com.cn Sent: Samstag, 8. Mai 2021 09:18 To: mohamed.boucadair@orange.com Cc: jmh@joelhalpern.com; sfc@ietf.org Subject: Re: [sfc] Fwd: IETF WG state changed for draft-ietf-sfc-nsh-tlv Thank you Med， Yes，you are right. Tenant ID in Section 4.1 and 4.2 are confusing. “Tenant ”is a common cloud orchestration proper noun, I suggest to use Forwarding Context ID in Section 4.1 Then keep "Tenant ID" for Section 4.2 Best Regards, Yuehua Wei M: +86 13851460269 E: wei.yuehua@zte.com.cn<mailto:wei.yuehua@zte.com.cn> 原始邮件 发件人：mohamed.boucadair@orange.com<mailto:mohamed.boucadair@orange.com> 收件人：Joel Halpern;sfc@ietf.org; 日 期 ：2021年04月29日 23:55 主 题 ：Re: [sfc] Fwd: IETF WG state changed for draft-ietf-sfc-nsh-tlv Hi Joel, all, The same concerns that I raised back in 01/21 are still valid for this version. I'm resending the comments, fwiw. ****** I would be more than happy to provide text but the issue is that I don't know what is the intent/purpose of many of these TLVs. Consider for example this one: == 4.7. Universal Resource Identifier [[removing the figure]] where URI (Universal Resource Identifier) Type is four bits-long field that specifies the format of the URI field. This document defines the following values for the URI Type field: * 0x1: URI in standard string format as defined in [RFC3986]. * 0x2: URI represented in a compacted hash format. == I fail to see what this URI is for and how it can be consumed by upstream SFs. The same applies for Ingress Network Node Information and Ingress Network Source Interface. Not clear to me how supplying this information will be useful for upstream SFs. Likewise, no clear what is the difference between the Tenant ID in Section 4.2 and 4.3. Why a tenant type is needed in 4.3, but not 4.2. The POLICY_ID and Tenant ID are likely to trigger similar discussion (at least by the IESG) as what is documented for Performance Policy Identification and Subscriber ID in draft-ietf-sfc-serviceid-header. The authors may grab whatever text recorded there, as appropriate. ***** Cheers, Med > -----Message d'origine----- > De : sfc [mailto:sfc-bounces@ietf.org] De la part de Joel Halpern > Envoyé : jeudi 29 avril 2021 17:40 > À : sfc@ietf.org<mailto:sfc@ietf.org> > Objet : Re: [sfc] Fwd: IETF WG state changed for draft-ietf-sfc-nsh- > tlv > > Thank you Donald.
