NSTAT features

Release 1.1 ("Eunomia") features

• Custom Mininet topologies: At the input *.json test configuration step, the user is now able to determine the creation of three different network topologies (disconnected, linear, mesh) when running stress tests with Mininet, see mininet_custom_topologies. The rationale is that these topologies act as levels regarding the communication complexity (number of transmitted messages) of topology-related messages (e.g. LLDP), and therefore further investigation of the controller's performance can be achieved.

• NB stress-test implementation: new test scripts have been implemented supporting stressing of controller's northbound interface. Further details can be found at Northbound active scalability tests with Mininet

• NB stress-test configurations: new JSON files that contain all configuration keys for northbound test-cases.

• Vagrant setup environment: new vagrant scripts are provided supporting the use of NSTAT within a special standalone virtual machine including all necessary NSTAT dependencies. This feature prevents users from polluting their hosts machines with redundant packages/installations when installing NSTAT.
