Quality of service (qos) configuration in low-power and lossy networks

An apparatus, comprising:

• one or more network interfaces to communicate in a computer network;
• a processor coupled to the 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 operable to:
• perform deep packet inspection on received packets at the apparatus to determine packet flows;
• calculate per-flow service level agreement (SLA) metrics for the packets based on timestamp values placed in the packets by respective origin devices in the computer network;
• compare the SLA metrics to respective SLAs to determine whether the respective SLAs are met;
• and
• in response to a particular SLA not being met for a particular flow, is download determined quality of service (QoS) configuration parameters to one or more visited devices along n calculated paths from a corresponding origin device for the particular flow to the apparatus.

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

• perform deep packet inspection on received packets at a distributed intelligence agent (DIA) in a computer network to determine packet flows;
• calculate per-flow service level agreement (SLA) metrics for the packets based on timestamp values placed in the packets by respective origin devices in the computer network;
• compare the SLA metrics to respective SLAs to determine whether the respective SLAs are met;
• and
• in response to a particular SLA not being met for a particular flow, download determined quality of service (QoS) configuration parameters to one or more visited devices along n calculated paths from a corresponding origin device for the particular flow to the DIA.

A method, comprising:

• receiving one or more timestamped packets at a minimalistic connected object (MCO) as a visited device along a path between an origin device of the packets and a distributed intelligence agent (DIA);
• forwarding the packets from the MCO without applying any deep packet inspection or quality of service (QoS) mechanisms to the packets;
• receiving downloaded QoS configuration parameters at the MCO from the DIA in response to a particular flow associated with the packets not meeting a corresponding service level agreement (SLA) according to the DIA, the QoS configuration parameters for future packets;
• and
• in response to receiving future packets at the MCO, applying the QoS configuration parameters according to the QoS configuration parameters from the DIA.
