Claim 8:
9. At least one non-transitory computer-readable storage medium comprising instructions stored therein, which when executed by one or more processors, cause the one or more processors to:
encode an in-situ Operation, Administration, and Maintenance (iOAM) instruction as a local argument in a function field of a Segment Routing over IPv6 segment identifier (SRv6 SID) corresponding to one or more segment routing nodes selected for iOAM data collection, wherein the SRv6 SID is selected from a plurality of SIDs included in an SID list of a segment routing header (SRH) associated with a first packet;
transmit the first packet to the one or more segment routing nodes selected for iOAM data collection;
receive a second packet containing the iOAM data from the one or more segment routing nodes selected for the iOAM data collection, wherein each of the one or more segment routing nodes selected for the iOAM data collection is configured to send a copy of the SRH containing the iOAM data to a controller; and
process the iOAM data from the one or more segment routing nodes selected for the iOAM data collection.
