Hi Shaofu, Thanks for your comments, please see inline. Regards, Peng liupengyjy@chinamobile.com From: peng.shaofu@zte.com.cn Date: 2022-04-18 19:55 To: liupengyjy@chinamobile.com CC: detnet@ietf.org; detnet-chairs@ietf.org; draft-liu-detnet-large-scale-requirements@ietf.org Subject: Re:[Detnet] New Version Notification for draft-liu-detnet-large-scale-requirements-02.txt Hi PengLiu, Thank you for thinking about the requirements of large-scale deterministic networks. I read your new section 5 and feel that its content needs further revision. In general, it has obvious scheme implication, which should go beyond the scope of requirements documents. For example, flow id field as descibed in section 5.1, cyclic queuing MUST be supported as described in section 5.2, explicit path as described in section 5.4. [PL] Not really the scheme implication in fact, we want the requirements to be reasonable and achievable. I think there are and will be multiple solutions proposed to meet those requirements and explain in more details how they are supposed to work. So, some comments for section 5: 1. It should not be limited to IPv6, and MPLS also needs to add queuing extension. [PL] Yes, the document does not limit to the IPv6. Most requirements apply to both. At the same time, we have to admit more attention should be taken in order to support IPv6 native large scale networks. MPLS have a good feature of label switching which naturally provides features like path selection. 2. The description of the treatment of the enhanced data plane is necessary. The treatment includes service protection, forwarding and queuing. [PL] The document is more for the purpose of high level requirements. We have covered something like when crossing the domains supporting different queuing the border node should be able to re-shape the packet and take this extra delay into account but still meet the e2e latency bounds requirement. We don't rule out suggestions on treatment, but so far we haven't seen any valuable points worthy of recognition. 3. The queue mechanism should not be limited to an individual mechanism, even for TSN it is still open to introduce more mechanisms. Not sure if there are data plane extensions for a general queue mechanism. [PL] There are some general requirements for queuing, for example, as mentioned in item 2, crossing domains with different queuing mechanisms in large scale networks. Also for each individual queuing, there may or may not require enhancement. If there is, that would be worth being documented in the requirement document. That’s what we tried to do.

Section 5 to cover the potential data plane requirement from the large scale deterministic networking was added. We'd like to ask you to review the document. Based on the WG's recharter discussion in ietf 113 and the earlier discussion on this document and its predecessors, we think this document can be used as the starting point of the milestone of “enhancement requirements” for WG. If the responses are not too averse, we will request a call for adoption this month. Thanks.

Name: draft-liu-detnet-large-scale-requirements Revision: 02 Title: Requirements for Large-Scale Deterministic Networks Document date: 2022-04-11 Group: Individual Submission Pages: 17 URL: https://www.ietf.org/archive/id/draft-liu-detnet-large-scale-requirements-02.txt Status: https://datatracker.ietf.org/doc/draft-liu-detnet-large-scale-requirements/ Htmlized: https://datatracker.ietf.org/doc/html/draft-liu-detnet-large-scale-requirements Diff: https://www.ietf.org/rfcdiff?url2=draft-liu-detnet-large-scale-requirements-02 Abstract: Aiming at the large-scale deterministic network, this document describes the technical and operational requirements when the different deterministic levels of applications co-exist and are transported over a wide area. This document also describes the corresponding Deterministic Networking (DetNet) data plane enhancement requirements. The IETF Secretariat
