JMeter Netconf Plug-in and Network Service Automation

Network service automation-related requirements are usually realized by means of commercial or open-source network orchestrator or controller software system.

In fact, it can be realized through a light-weight way, JMeter Netconf plug-in implementation and network service automation process customization without compiled code based on JMeter framework.

JMeter Netconf plug-in implementation includes two modules.
