Hi Francis, Thanks for your feedback. Since Traceroute is not a standard, but rather an application, it has several implementations. Indeed, the UNIX implementation uses UDP messages - this is also described in RFC 2151 (informational). The windows implementation of Traceroute, on the other hand, uses ICMP Echo messages, see: http://technet.microsoft.com/en-us/library/bb491018.aspx
So I think maybe the draft should explain that Traceroute is an application that has more than one implementation, and that it can be implemented with either UDP or ICMP messages. Does this make sense? Thanks.

Document: draft-ietf-opsawg-oam-overview-05.txt Reviewer: Francis Dupont Review Date: 20110723 IETF LC End Date: 20110720 IESG Telechat date: unknown Summary: Not Ready Major issues: 4.1 page 13 explains the use of ICMP in Traceroute: this is plainly wrong: ICMP can't be used in this way because no ICMP error can be triggered by an ICMP. BTW: - traceroute uses UDP probes just for this reason - I put this as a major issue because this must not be published in a document from the IETF Regards [email protected] PS: I stopped the review at this point but I'll resume and send a full review ASAP (I like the document, OAM is something really useful and to try to organize it a great idea). _______________________________________________ Gen-art mailing list [email protected] https://www.ietf.org/mailman/listinfo/gen-art
