Hi Zhenqiang, Thanks for your review comments. Please see inline with <RG>.. From: ippm <ippm-bounces@ietf.org> on behalf of li_zhenqiang@hotmail.com <li_zhenqiang@hotmail.com> Date: Thursday, May 13, 2021 at 12:18 AM To: Tommy Pauly <tpauly=40apple.com@dmarc.ietf.org>, ippm <ippm@ietf.org> Subject: Re: [ippm] I-D Action: draft-gandhi-ippm-stamp-srpm-03.txt Hello Tommy and All, I believe this work is useful, especially the way to direct the session-reflector to reflect the test packets along a specific path, which can be the reverse path from session-sender to session-reflector, or an explicit path specified in segment list sub TLV. <RG> Thanks. I wonder there are security problems redarding the return address sub tlv since this feature can be used to direct the test packets to a malicious node indicated by the return address. This feature may also be used to direct a group of session-reflectors to send their test packets to a target node indicated by the return address to enforce DDOS attack to the target. Security Considerations should take these into account. <RG> Agree. Following text was proposed in another email thread. “The STAMP extensions defined in this document may be used for potential "proxying" attacks. For example, a Session-Sender may specify a return path that has a destination different from that of the Session-Sender. But normally, such attacks will not happen in an SR domain where the Session-Senders and Session-Reflectors belong to the same domain. In order to prevent using the extension defined in this document for proxying any possible attacks, the return path has destination to the same node where the forward path is from.“ Welcome your review comments. Thanks, Rakesh BTW, is this an adoption call for this draft?

Title : Simple TWAMP (STAMP) Extensions for Segment Routing Networks Authors : Rakesh Gandhi Clarence Filsfils Daniel Voyer Mach(Guoyi) Chen Bart Janssens Richard Foote Filename : draft-gandhi-ippm-stamp-srpm-03.txt Pages : 12 Date : 2021-04-29 Abstract: Segment Routing (SR) leverages the source routing paradigm. SR is applicable to both Multiprotocol Label Switching (SR-MPLS) and IPv6 (SRv6) data planes. This document specifies RFC 8762 (Simple Two-Way Active Measurement Protocol (STAMP)) extensions for SR networks, for both SR-MPLS and SRv6 data planes by augmenting the optional extensions defined in RFC 8972.
