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

摘要

In one embodiment, a distributed intelligence agent (DIA) in a computer network performs deep packet inspection on received packets to determine packet flows, and calculates 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. By comparing the SLA metrics to respective SLAs to determine whether the respective SLAs are met, then in response to a particular SLA not being met for a particular flow, the DIA may 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. In addition, in one or more embodiments, the QoS configuration parameters may be adjusted or de-configured based on whether they were successful.

1. 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.
