Web application which communicate with ONOS endpoint and s-flow endpoint

Build a Web app , see attachments 1-)The project requires detection of distributed denial of service attack in sdn environment by using s-flow(sample flow) technology. 2-)The project should be performed with ONOS Controller and it is necessary to communicate multiple ONOS clusters. Two of them are sufficient. 3-) Distributed clusters should be able to send ping request from one host under the first cluster to another host under the second cluster. 4-)A web application should be developed and the application should communicate both ONOS endpoint and s-flow [login to view URL] switch should be controlled and determined for which point on the network is under attack. 5-)In order to handle continuous flows, it is required to use a queue system like Apache Kafka.
