Abstract: 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.

Abstract: A method for using metadata in an Internet Protocol (IP) packet is provided. A first processor at a first node sets a dedicated field of the IP packet to a predetermined value to indicate that metadata is present in the IP packet, and adds metadata to the IP packet by inserting the metadata between an original transport header of the IP packet and an original packet payload of the IP packet. A second processor at a second node receives the IP packet from the first node, reads the dedicated field to identify the predetermined value indicating that metadata is present in the IP packet, and identifies the metadata in the IP packet based on the predetermined value.

Abstract: 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 a select number of the data packets. The OAM header includes a data type bitmap and a node data list. A valid node bitmap is inserted into the OAM header prior to the node data list, and each bit in the valid node bitmap identifies whether one or more nodes in the network add data to the OAM header. A valid data bitmap is then added into the OAM header for each of the one or more nodes identified as adding data to the OAM header. The valid data bitmap indicates types of data items available at the node. Subsequently, the edge node issues the select data packets to the one or more nodes identified in the OAM header.

Abstract: A mechanism for adaptively performing in-band network telemetry (INT) by a network controller is disclosed. The mechanism includes receiving one or more congestion indicators from a collector. An adjusted sampling rate is generated. The adjusted sampling rate is a specified rate of insertion of instruction headers for INT and is generated based on the congestion indicators. The adjusted sampling rate is transmitted to a head node, which is configured to perform INT via instruction header insertion into user packets.
