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 collapsible truss and method that is particularly suitable for staging and lighting, for shows, performances and other events. This evolved and novel modular truss can be collapsed to a significantly smaller size (i.e. increased density), and consequently requires significantly less space for storage and transportation. Further, in addition to the advantage of rapid assembly from collapsed parts to a full truss, the modular construction of the truss provides cost effective repair of this truss over traditional rigid welded trusses by simple replacement of damaged parts.
