The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-i2rs-yang-network-topo/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- I agree with Kathleen's discuss points and have one more aspect to offer that I hope you include in that discussion: This model I think will lead designers to only think about the nodes that are supposed to have access to traffic. (See also below about broadcast media.) The model will generally not capture the reality that some other nodes can also actually see or influence traffic and I think that will lead to vulnerabilities not being recognised. I don't have a good suggestion for how to fix that problem but I do think you ought mention it as a security consideration, e.g. something like: "For models such as these - the real world network may allow additional communications or links that are not represented in the model and such links may enable vulnerabilities that are liable to be missed when considering only the model. These models don't really capture the security or privacy aspects of the network." - 4.2 and generally: It is not clear to me how to represent broadcast media (e.g. radio) nor how IP multicast would be reflected in this model. I assume those can be done but as a bit of a hack. - nit: 6 authors and 4 contributors. I wish people (esp chairs) would just enforce the 5 author guideline and say why that's inappropriate in the few instances in which that is the case. _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs
