Overview

Attention!

THIS NAPP IS STILL EXPERIMENTAL AND IT'S EVENTS, METHODS AND STRUCTURES MAY CHANGE A LOT ON THE NEXT FEW DAYS/WEEKS, USE IT AT YOUR OWN DISCERNMENT

The NApp kytos/pathfinder is a NApp responsible for creating a graph with the latest network topology and providing rest endpoint to calculate the best path between two devices. In the network, each device is a host or a switch and each link is a connection between two devices. In the graph, each device represents a node and each link represents an edge between two nodes.

The NApp learns custom properties from the topology, being able to define the best paths based on a weighted parameter. Please see the Rest API documentation for details.
