Remote stitched directed acyclic graphs

An apparatus, comprising:

• one or more network interfaces to communicate in a computer network;
• a processor coupled to the one or more network interfaces and adapted to execute one or more processes;
• and
• a memory configured to store a process executable by the processor, the process when executed configured to:
• detect a trigger condition at a particular location in a primary directed acyclic graph (DAG) in the computer network, wherein the primary DAG includes a root node of the primary DAG;
• determine a particular node in the primary DAG at the particular location to act as a remote stitched (RS)-DAG root for an RS-DAG at the particular location, wherein the particular node is a different node in the primary DAG than the root node of the primary DAG;
• instruct the RS-DAG root to initiate the RS-DAG, the instructing indicating one or more properties for the RS-DAG that are selected to cause additional data regarding the trigger condition to be collected within the RS-DAG and that are different from properties of the primary DAG, wherein a particular child node of the RS-DAG root in the RS-DAG has a different parent node in the primary DAG;
• and
• receive a conclusion message from the RS-DAG root that aggregates the additional data regarding the trigger condition collected within the RS-DAG.

A tangible, non-transitory, computer-readable media having software encoded thereon, the software when executed by a processor configured to:

• detect a trigger condition at a particular location in a primary directed acyclic graph (DAG) in a computer network, wherein the primary DAG includes a root node of the primary DAG;
• determine a particular node in the primary DAG at the particular location to act as a remote stitched (RS)-DAG root for an RS-DAG at the particular location, wherein the particular node is a different node in the primary DAG than the root of the primary DAG;
• instruct the RS-DAG root to initiate the RS-DAG, the instructing indicating one or more properties for the RS-DAG that are selected to cause additional data regarding the trigger condition to be collected within the RS-DAG and that are different from properties of the primary DAG, wherein a particular child node of the RS-DAG root in the RS-DAG has a different parent node in the primary DAG;
• and
• receive a conclusion message from the RS-DAG root that aggregates the additional data regarding the trigger condition collected within the RS-DAG.

A method, comprising:

• receiving, by a network device that is a particular node at a particular location in a primary directed acyclic graph (DAG) in a computer network, instructions to initiate a remote stitched (RS)-DAG by the particular node as an RS-DAG root, the instructions indicating one or more properties for the RS-DAG that are different from properties of the primary DAG, wherein the RS-DAG root is a different node in the primary DAG than a root node of the primary DAG;
• initiating, by the network device, the RS-DAG from the RS-DAG root to collect additional data within the RS-DAG regarding a triggering condition, wherein a particular child node of the RS-DAG root in the RS-DAG has a different parent node in the primary DAG;
• and
• relaying, by the network device, messages of the RS-DAG between the RS-DAG root and the root node of the primary DAG that include the collected additional data.
