I find it ***weak*** on several points (see below) and more accurate language will be welcome rather than hand waving. I strongly suggest that the authors/WG have a second pass on the document." The document is very hand-wavey, and, based on the number of open comments and nits, does not appear to have had significant detailed review; I almost balloted DISCUSS because of this. This document would benefit from copy-editing. 1: The document opens with: "Here are some of the main characteristics of "SD-WAN" networks: [...]" -- I don't really think that most of these are "the main characteristics of "SD-WAN" networks" - e.g: "Instead of all traffic hauled to Corporate HQ for centralized policy control, direct Internet breakout from remote branch offices is allowed." - this is a characteristic of many many different technologies and VPN solutions. The implication of this sentence so early in the document is that a: these are differentiating characteristics, and b: that they are the **main** characteristics. 2: Editorial: "Instead of all traffic hauled to Corporate HQ for centralized policy control, direct Internet breakout from remote branch offices is allowed." - "Instead of hauling all traffic to ..." or "Instead of having all traffic hauled to..." or... 3: "Some traffic can be forwarded by edge nodes, based on their application identifiers instead of destination IP addresses, by placing the traffic onto specific overlay paths based on the application-specific policies." - the subject of this sentence is very unclear. What is this "some traffic" (why not all? what does "some" do in this sentence?). Same for "their" in "their application identifiers". 4: "CPE-Based VPN: Virtual Private Secure network formed among CPEs. This differentiates from more commonly used PE-based VPNs". How does "VPN" expand to "Virtual Private Secure network"? **How** this this "differentiates" from more commonly used PE-based VPNs? ("This differs from more commonly used PE-based VPNs as it is formed between CPE" would sort of work, but it is still very unclear *why* this is being noted. 5: "SD-WAN: Software Defined Wide Area Network is an overlay network ..." - this is a much better definition than how the document was opened. I suggest that it be used if you want to introduce what SD-WAN **is**. 6: "Conventions used in this document [...] SD-WAN over Hybrid Networks: SD-WAN over Hybrid Networks typically have edge nodes... You never actually use that term - you *do* use Hybrid Underlay (e.g "SD-WAN with Hybrid Underlays") a bunch of times though. 7: "For multicast packets forwarding" -> "For multicast packet forwarding" _______________________________________________ BESS mailing list BESS@ietf.org https://www.ietf.org/mailman/listinfo/bess
