The early review can be performed at any time during the draft's lifetime as a working group document. The purpose of the early review depends on the stage that the document has reached.

Cloud DCs) alongside with mitigation practices. I have some minor concerns about this document that I think should be resolved before it is submitted to the IESG. Comments/Minor Issues: - Abstract: "today" --> "at the moment of writing this specification" ? [Linda] changed. - Section 1: The abstract mentions that the problems are related to MPLS, but the introduction does not mention it. Furthermore, it would be nice to explain why these 8 problems (Section 3) were selected in relation with MPLS. [Linda] changed the MPLS networks to "traditional VPN networks". MPLS is just one example. We believe those 8 problems are the network-related problems enterprises face at the moment of writing this specification when interconnecting their branch offices with dynamic workloads in third-party data centers. If you can list more, please elaborate. - Section 2, VPC: "... Most Cloud operators' VPCs only support...." --> "at the moment of writing this specification, most Cloud operators' VPCs only support...." ? [Linda]changed. - Section 3: * " There are many problems associated with connecting to hybrid Cloud" --> "... connecting to Cloud DCs" ? In this way, it is aligned with the title. [Linda] changed. * Some mitigations include references, but It would be nice to add references to all of them. * It would be nice to add in each mitigation, the costs of applying it. [Linda] the cost depends on the service providers. It is out of the scope of this document to describe the cost. - Section 3.1: * "it MUST ignore..." --> it must ignore ... ? [Linda] changed. * "BGP session MUST NOT ..." --> BGP session must not ...? [Linda] changed. - Section 3.2: * "BFD" --> Bidirectional Forwarding Detection (BFD) ? [Linda] changed. * What means a site capacity goes dark? [Linda] Meaning the capacity goes to zero - Section 3.4: * It would be nice to add a reference to 5G, specially when mentions the 5G core functions [Linda] Added the reference to 3GPP TS 23.548 v18.1.1, "5G System Enhancements for Edge Computing", April 2023. * The mentioned problems and mitigations applies for 5G Standalone and Non-Standalone deployments options? [Linda] The 3GPP's Edge Computing is for 5G only. - Section 3.5: "More diligents security procedures..." --> it would be nice to add some examples, "More diligents security procedures such as (add example) [add reference] need to be considered..." [Linda] changed the text to "Additional Internet security procedures need to be designed that are able to mitigate all these issues. - Section 3.7: suggestion to add the URL as a reference (https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.aws.amazon.com%2FAmazonVPC%2Flatest%2FUserGuide%2Fvpc-&data=05%7C01%7Clinda.dunbar%40futurewei.com%7C5e5b2dc071a44e2f3d5108db392c17c8%7C0fee8ff2a3b240189c753a1d5591fedc%7C1%7C0%7C638166633779772763%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=%2F6CeF%2FS4yv2CMIPhVxm1ilxNyujV83IMkAPkew6rOyA%3D&reserved=0 nat-gateway.html#nat-gateway-other-services) [Linda] Changed. Also added Azure NAT reference. Section 6: * "now" --> "at the moment of writing this specification" ? [Linda] changed. * Parenthesis opened at Internetworking, but it is not closed [Linda] added. Section 7: * Should a reference to rfc5920 be added? [Linda]RFC5920 is about MPLS security. This document is more about using IPsec to connect to Cloud DCs. Therefore, I don't think it is necessary to reference the rfc5920. * Maybe could be added similar text as the sec considerations of draft-ietf-rtgwg-net2cloud-gap-analysis ? [Linda] gap analysis draft is only for guiding the group discussion, is not going towards RFC. - Question: draft-ietf-rtgwg-net2cloud-gap-analysis should be added in the references? both drafts seems quite related. [Linda] gap analysis will not be published. Thank you for this document, Ines
