"""Testbed modelling.

This package defines the testbed elements DTS works with:

    * A system under test node: :class:`~.sut_node.SutNode`,
    * A traffic generator node: :class:`~.tg_node.TGNode`,
    * The ports of network interface cards (NICs) present on nodes: :class:`~.port.Port`,
    * The logical cores of CPUs present on nodes: :class:`~.cpu.LogicalCore`,
    * The virtual devices that can be created on nodes: :class:`~.virtual_device.VirtualDevice`,
    * The operating systems running on nodes: :class:`~.linux_session.LinuxSession`
      and :class:`~.posix_session.PosixSession`.

DTS needs to be able to connect to nodes and understand some of the hardware present on these nodes
to properly build and test DPDK.
