Abstract:
The present technology provides a system and method for implementing targeted collection of in-situ Operation, Administration and Maintenance data from select nodes in a Segment Routing Domain. The selection is programmable and is implemented by setting an iOAM bit in the function arguments field of a Segment Identifier. In this way only the nodes associated with local Segment Identifiers (Function field of a Segment Identifier) with an iOAM argument bit are directed to generate iOAM data. The iOAM data generated by target nodes may be stored in TLV field of the segment routing header. The Segment Routing packet is then decapsulated at a Segment Routing egress node and the Header information with the collected iOAM data is sent to a controller entity for further processing, analysis and/or monitoring.
