Abstract: A network automation system platform is described herein for carrying out a method for automated multi-node performance validation testing on a communications network. The method includes acquiring a test configuration for executing a multi-node performance validation test, wherein the test configuration identifies: a multi-node network performance test, carried out by an application layer, that specifies a technology-independent test script that is generic to particular technologies for providing performance validation-related services, and a node group upon which the multi-node network performance test is to be performed. The method further includes executing the multi-node network performance validation test by the application layer issuing requests to a core layer comprising a set of technology-specific services that issue, in accordance with the application layer requests, technology-specific commands to external services during performance validation of nodes within the node group.

Abstract: A floating wing apparatus for toolbars which allows each wing to ride smoothly over terraced or rolling terrain, thereby providing a continuous, even contact between the implements carried thereon and the ground. Upper and lower pivot arms extend from the central section of the toolbar to the inner end of each wing section to form a parallelogram linkage which maintains the wing sections in a substantially horizontal orientation at all times, whether in the raised or lowered position. The upper pivot arm is pivotally connected to a pivot post, which is in turn pivotally connected to the central section. When working the land, this pivot post allows the wing sections and their attached implements to float or ride over uneven, rolling terrain. When the implements must be raised above the ground as during turning at the end of a field or when the wings are raised to the retracted position, the pivot posts are locked to a vertical position by means of hydraulic cylinders.
