  • Spirent TestCenter
  • Virtual LabServer
  • vLS
  • Session Manager
  • Virtual License Server
  • Virtual Controller

Generally speaking, this is the explanation for each:

1.    Spirent Virtual LabServer

Spirent TestCenter LabServer (a.k.a “Spirent vLS”) is a virtual machine deployed with off-the-shelf hypervisors that provide the solution that eliminates the need for a dedicated test management console computer and supports team collaboration during testing.

2.    Spirent Virtual License Server

Spirent Virtual License Server (a.k.a “Virtual Controller”) is also a virtual machine that basically manages/control licenses. The license server is only required if you are using a virtual chassis and it is optional for physical chassis. So, on this VM you install the licenses that serves the virtual ports licenses, hence through the normal GUI the virtual ports would check for licenses needed in bulk through a connection with the License Server.
