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.

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.

BTW, is this an adoption call for this draft?

Best Regards,
Zhenqiang Li

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.
