  • Patent number: 11991069
    Abstract: Techniques and architecture are described grouping various sources of traffic within a network into grouping fields and assigning each combination of grouping field values an aggregate identification (ID). A first hop edge router may receive a packet and search a mapping table for a corresponding aggregate ID for the combination of grouping field values within the mapping table. If not found, the first hop edge router may assign a corresponding aggregate ID for the combination of grouping field values and store the new aggregate ID for the combination of grouping field values in the mapping table. The first hop edge router may forward the packet on through the network with the aggregate ID embedded in metadata. Routers within the network may measure and aggregate flow metrics of the packet within the network based on the aggregate ID and provide the measurements to the network controller.

  • Patent number: 11985211
    Abstract: A telemetry producer sends a hello message to a telemetry registration interface. The interface returns a hello message. The producer sends a producer protocol suite to the interface. An acceptance of the protocol suite and an indication that the protocol suite has been forwarded to a telemetry registration controller is returned. The producer sends a hello message to the controller. The controller returns an acknowledgement and a producer identifier (ID). A second hello message and the producer ID is sent from the producer to the controller. The controller returns a second acknowledgement and the producer ID, indicating the producer registration. A telemetry consumer sends the controller a hello message. An acknowledgement with a consumer identifier (ID), is returned to the consumer. The consumer sends a consumer request packet to the controller. The controller sends the producer ID, and an indication of consumer registration to the consumer.
