Abstract:
A method for performing in-band operations, administration, and management (OAM) using fixed bytes. According to one aspect, data packets are selected from a packet flow according to a sampling rate. A network device's OAM information is inserted into a fixed length field of each selected packet as a selected packet is processed by the network device.

Claim (Index 12):
A network comprising:\n a plurality of network devices configured to:\n select, by each network device of the plurality of network devices, a varying subset of packets from a packet flow according to a sampling rate; and \n insert, by each network device of the plurality of network devices, in-band operations, administration, and management (OAM) information corresponding to the network device into a fixed length field of each packet in the varying subset of packets as each packet in the varying subset of packets passes through the network device; and \n a network controller configured to:\n initialize the sampling rate used for selecting the packets from the packet flow; \n perform a flow characterization process to determine whether the sampling rate is sufficient for characterizing an entire flow of the packet flow; and \n responsive to a determination that the sampling rate is not sufficient for characterizing the entire flow of the packet flow, adjusting the sampling rate of the plurality of network devices.
