Test Methodology

Twister Test Execution platform interacts with SuperCloud orchestrator through API

Twister displays topology information about switches and controllers via orchestrator plugin

SuperCloud Orchestrator is integrated with Ryu OF controller for OpenFlow 1.3 messages

Twister components Central Engine(CE) and Execution Engine(EE) are distributed and are virtual machines on top of KVM hypervisor

Twister CE fires OF Conformance and Performance test scripts

Twister initiates traffic from traffic generator for benchmark tests

Twister platform shows report results for switch conformance and performance

Open Source Test Execution: Luxoft Twister platform

SDN Orchestrator: Luxoft SuperCloud platform

Open Source OF Controller: NTT Ryu

Open Source OF Switches: OVS 2.1.2, Flowforading.org LINC, Floodlight Indigo
