Abstract:
A method is provided to configure a communication network to perform telemetry of OAM data, implemented in a network management device. A packet flow ID is identified, and a head node and an end node for the packet flow are determined from the flow ID. A marking command is sent to the head node, causing it to mark some packets in the packet flow. An unmarking command is sent to the end node, causing it to unmark marked packets. A path configuration command is received, including a list of nodes through which a marked packet passed. A command is sent to the nodes in the list, configured to cause the nodes to collect specified OAM flow data relating to marked packets. Such data for an individual packet is received after being collected from the nodes in the list. The OAM flow data is used to improve performance of the network.

Claim (Index 1):
A method for configuring a communication network to perform postcard-based telemetry (PBT) of operations, administration, and management (OAM) data, implemented in a network management device (NMD), the method comprising:\n identifying a monitored flow identifier (ID) for a packet flow and determining from the monitored flow ID at least one head node and at least one end node for the packet flow in a communication network; sending a marking command to each determined head node, the marking command comprising the monitored flow ID and configured to cause the head node to mark at least some packets in the packet flow; sending an unmarking command to each determined end node, the unmarking command comprising the monitored flow ID and configured to cause the end node to unmark marked packets in the packet flow; in response to the marking command, receiving a path configuration command comprising a list of PBT-aware nodes in the communication network through which a packet in the packet flow passes; in response to receiving the path configuration command, sending an OAM data set template command to the PBT-aware nodes identified in the list, the OAM data set template command comprising the monitored flow ID and a specification of OAM flow data, the OAM data set template command configured to cause the PBT-aware nodes to collect the specified OAM flow data relating to marked packets in the packet flow; and in response to the OAM data set template command, receiving OAM flow data for an individual packet in the packet flow and using the OAM flow data to improve performance of the communication network, the OAM flow data being collected from the PBT-aware nodes identified in the list.
