I cannot support this draft in its current form, primarily because of the following assessment regarding IP VPNs:
Section 3.1: "There are number of VPN approaches that provide some of the desired semantics of virtual networks (e.g., [RFC4364]). But VPN approaches have traditionally been deployed across WANs and have not seen widespread deployment within enterprise data centers. They are not necessarily seen as supporting the characteristics outlined in Section 2.7." The "characteristics" listed in section 2.7 are supported by IP VPNs. The number 4 "characteristic" in section 2.7 (which is quite vague IMO) would not be met by number of proposals (listed in section 4) since they require new software. Hence, the IP VPN description is clearly out of place in section 3.1. Another comment that I want to make is on section 3.3: Section 3.3: "From an architectural perspective, one can view the address mapping dissemination problem as having two distinct and separable components. The first component consists of a back-end "oracle" that is responsible for distributing and maintaining the mapping information for the entire overlay system. The second component consists of the on-the-wire protocols an NVE uses when interacting with the oracle." This is exactly what marques-end-systems proposes. I think it would be important (for completeness) to refer to this draft in draft-narten-nvo3-overlay-problem-statement-02. Thanks.
