TLDR
In this paper, a data aggregator discovery (DAD) message may be distributed by an associated DAG through the recorded route and via the data aggregators, the DAD message identifying the initiating DAG, and comprising a recorded route taken from the DAG to a receiving particular node as well as a total path cost for the particular node to reach a root node of the DL through the record route and through the data aggregation via the DL.Abstract:
In one embodiment, a data aggregator discovery (DAD) message may be distributed by an associated data aggregator, the DAD message identifying the initiating data aggregator, and comprising a recorded route taken from the data aggregator to a receiving particular node as well as a total path cost for the particular node to reach a root node of the DAG through the recorded route and via the data aggregator The receiving particular node determines a path cost increase (PCI) associated with use of the data aggregator based on the total path cost as compared to a DAG-based path cost for the particular node to reach the root node via the DAG If the PCI is below a configured threshold, the particular node may redirect traffic to the data aggregator as source-routed traffic according to the recorded route The traffic may then be aggregated by the data aggregator, accordinglyread more

Distributed model training
TL;DR: In this article, a machine learning model is to be trained by a plurality of devices in a network, with each of the training devices having a local set of training data, and an instruction is sent to each device that is configured to cause a training device to receive model parameters from a first training device in the set.
Patent
Learning model selection in a distributed network
TL;DR: In this paper, local model parameters are generated by training a machine learning model at a device in a computer network using a local data set and performance metrics for model parameters for the device and the one or more other devices using the received performance metrics.
Patent
Adaptive routing using inter-switch notifications
TL;DR: In this paper, the authors propose a method to detect in a network switch of a communication network communication traffic that originates from a source node and arrives over a route through the communication network traversing one or more preceding network switches.

RPL: IPv6 Routing Protocol for Low-Power and Lossy Networks
TL;DR: This document specifies the IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL), which provides a mechanism whereby multipoint-to-point traffic from devices inside the LLN towards a central control point as well as point- to- multipoint traffic from the central control points to the devices insideThe LLN are supported.
Routing Metrics Used for Path Calculation in Low-Power and Lossy Networks
TL;DR: This document specifies a set of link and node routing metrics and constraints suitable to low power and Lossy Networks.

TL;DR: In this paper, a path verification protocol (PVP) enumerates a series of messages sent to a set of nodes, or routers, along a suspected path, identifies forwarding plane problems for effecting changes at the control plane level.
Reactive Discovery of Point-to-Point Routes in Low-Power and Lossy Networks
TL;DR: This document specifies a point-to-point route discovery mechanism that allows an IPv6 router to discover "on demand" routes to one or more IPv6 routers in a Low-power and Lossy Network (LLN) such that the discovered routes meet specified metrics constraints.

Methods and apparatus for managing data distribution in a network
TL;DR: In this paper, the authors present a real-time distributed data distribution in a network, in which a source or root node distributes data (e.g., video data) throughout a network of nodes by distributing data from parent to child through a tree of nodes.
