I am also wondering if hop-by-hop options been considered for this application? Their interpretation in the network is unabiguous and they also have the advantage that the work with any IP protocol or encapsulation. IPv6 hop-by-hop options has been considered. See

Tom, the term "overhead" here refers to the number of extra bytes used in the parent protocol to carry IOAM data. IOAM data itself is of course not counted for the comparison, because it would need to be carried in both cases. Using your Geneve reference as an example, in order to carry IOAM

Hi, It said in draft-brockners-ippm-ioam-vxlan-gpe-00: " [I-D.ietf-nvo3-vxlan-gpe] defines an "O bit" for OAM packets. Per [I-D.ietf-nvo3-vxlan-gpe] the O bit indicates that the packet contains an OAM message instead of data payload. Packets that carry IOAM data fields in addition to
