It uses an experimental TLV in the Segment Routing\r\nHeader (SRH); thus, participation in this experiment should be\r\nbetween coordinating parties in a controlled domain. This approach\r\nhas potential scaling and simplification benefits over the technique\r\ndescribed in RFC 9343, and the scope of the experiment is to\r\ndetermine whether those are significant and attractive to the\r\ncommunity.\r\n\r\nThis protocol extension has been developed outside the IETF as an\r\nalternative to the IETF's Standards Track specification RFC 9343 and\r\nit does not have IETF consensus. It is published here to guide\r\nexperimental implementation and ensure interoperability among\r\nimplementations to better determine the value of this approach. \r\nResearchers are invited to submit their evaluations of this work to\r\nthe Independent Submissions Editor or to the IETF SPRING Working\r\nGroup as Internet-Drafts.","pub_date":"March 2026","keywords":["SRH","TLV","Extension","Header","Option","Performance","Measurement","Monitoring","Passive","Hybrid","Loss","Delay","Delay Variation","Multipoint","Cluster","Closed-Loop"],"obsoletes":[],"obsoleted_by":[],"updates":[],"updated_by":[],"see_also":[],"doi":"10.17487\/RFC9947","errata_url":null}
