In-situ OAM Trace Type Extension with Cascade Bitmap and Segment In-situ OAM

The disclosure relates to technology for sending network management information in a network. A source edge node modifies data packets by encapsulating an operations, administration and maintenance (OAM) header in the data packets traversing a data path, and the OAM header includes a first indicator field. The source edge node also inserts a segment size field into the OAM header of the data packets based on an indication by the first indicator field, the segment size field indicating the data path is partitioned into segments based on a value of the segment size field.
