Document: draft-ietf-dime-drmp-04 Reviewer: Meral Shirazipour Review Date: 2016-03-24 IETF LC End Date: 2016-03-24 IESG Telechat date: NA Summary: This draft is ready to be published as Standards Track RFC but I have some comments. Major issues: Minor issues: -[Page 7], "The mechanism for how the agent determines which requests are throttled is implementation dependent and is outside the scope of this document. " Shouldn't all nodes handshake the mechanism to use to avoid countering each other's throttling decision/effect? -Security: Security section is well written but not convincing that the method described in this draft is a viable solution specially for first responder and public safety scenarios. Section 11.2 says DDOS is not an imminent thread but a few compromised nodes could send heavy load of high priority requests - I may be missing something here? Nits/editorial comments: -[Page 2], Please spell out DOIC at first use "Diameter Overload Indication Conveyance" -[Page 3], second sentence would read better as: old: "For instance it might be considered important to reduce the probability of transactions involving first responders during a period of heavy signaling resulting from a natural disaster being throttled during overload scenarios. " new (suggested): "For instance it might be considered important to reduce the probability of transactions involving first responders being throttled during overload scenarios caused for example by a period of heavy signaling resulting from a natural disaster. " -[Page 3], "the DIOC reacting node", should it be DOIC? -[Page 4], Please spell out AVP at first use (currently done in Section 9) -[Page 6], "Platinum SLA the includes"--->"Platinum SLA that includes" -comment on above sentence? (should we say in case net neutrality rules are not in place, ...." ? -[Page 6], sentence below did not read well. old: "In this scenario it is requests with the same command code that have different implied priorities. " new (suggested): "In this scenario requests with the same command code have different implied priorities. " -[Page 6], Please spell out ULR at first use -[Page 7] -[Page 7], [Page 8], and [Page 9] "non supportant"--->"non-supporting" -[Page 12], "which requests are are"--->"which requests are" -[Page 13], Please spell out TCP, SCTP, TLS, DTLS at first use -[Page 14], "degrated"--->"degraded" Best Regards, Meral --- Meral Shirazipour Ericsson Research www.ericsson.com
