Enabling external routing logic in ONOS with Intent Monitor and Reroute service

SDN intent-based networking allows programmers to specify high-level policies without worrying about the low-level configurations which are compiled by the controller. Our Intent. Monitor and Reroute service (IMR) extends the capabilities of ONOS Intent Framework by allowing to both compile multiple intents together and to re-optimize their paths, according to the network state and their flow statistics, via off-platform applications (OPA). In this demo we show two examples of intent based ONOS application whose network performance can be improved, with no modifications to their code, exploiting the IMR service.
