The invention relates to a method of connecting applications to applications, hardware to hardware, and applications to hardware, and a distributed architecture system for facilitating modular communication between a plurality of applications, a plurality of devices, and a plurality of applications and devices.
2. Background
Today's Test and Measurement systems are monolithic in nature where a given system supports at most a handful of closely related, tightly integrated stimulus and measurement capabilities. Systems take on the personality and characteristics of the specific stimulus and measurement capability and are limited to supporting this personality and characteristics. Even systems which are designed on a modular platform are truly monolithic in nature where only a given set of closely related, tightly integrated capabilities can be supported at a given time. To support a different capability, the modular system must transform to this new capability completely. Often systems have to be powered down and re-powered back up so that the monolithic software can install the specific drivers for the installed hardware capability.
Today's monolithic, non-distributed systems limit the ability of the user to support different measurement and stimulus capabilities simultaneously. These solutions also require a tight coupling, typically through direct hardware connection. The exposure of the stimulus and measurement capability through a User Interface is tightly coupled with the actual stimulus and measurement hardware. The User Interface is also heavily integrated with the system software. Even if the User Interface is created as a separate Application Layer, it is tightly coupled with the system software, the system hardware, and the module hardware. The module driver is also heavily integrated with the system software. This is clearly shown in those situations where the system must be fully restarted when the module is changed so the new personality and the new module driver can be loaded specifically. With today's systems, a user cannot test their entire system unless that system is covered by the handful of closely related, tightly integrated stimulus and measurement capabilities.
As an example, customers often wish to test a complete communication network path crossing the fiber optic/copper boundary. They want to measure the transmission characteristics and signal parameters on the fiber component of the network and also measure the transmission characteristics and signal parameters on the copper component of the network. Today, a customer would have to either have two completely different units—one configured as a fiber test platform and one configured as a copper fiber test platform (assuming a modular platform). It may be very expensive to have two complete modular systems. Otherwise, if the customer wants to control costs, the customer needs to configure their modular system as a fiber tester, test the fiber component and then reconfigure their modular system to a copper tester and test the copper component. This increases test time. This also increases opportunity for both false failures and false positives.
Today's monolithic software architectures are also specifically designed for a given hardware base. They are designed to run on a given Operating System (ex. Windows or Linux) but also on a custom designed set of hardware made up processor, memory, support peripherals, storage, and communication. To support movement to a different hardware base, the software would need to be redesigned and re-architected as it is tightly integrated with the hardware it runs on. Though a new processor of similar capability can be designed into their hardware base, a wholesale change to a different hardware base, or a different Operating System is not possible due to the closely integrated nature of their system design.

Various changes, modifications, and equivalents of the systems, apparatuses and/or methods described herein will suggest themselves to those of ordinary skill in the art. Descriptions of well-known functions and structures are omitted to enhance clarity and conciseness.
The terms used in the description are intended to describe embodiments only, and shall by no means be restrictive. Unless clearly used otherwise, expressions in a singular from include a meaning of a plural form. In the present description, an expression such as “comprising” or “including” is intended to designate a characteristic, a number, a step, an operation, an element, a part or combinations thereof, and shall not be construed to preclude any presence or possibility of one or more other characteristics, numbers, steps, operations, elements, parts or combinations thereof.
The present invention applies to distributed architecture which separates a test and measurement system into key components of which all are interchangeable on a hardware and software level. An exemplary embodiment of the present invention comprises a hardware-agnostic, application-agnostic Test Operating System (referred to as a Platform), a virtual instrumentation layer which allows for any given stimulus and measurement capability to be abstracted to an unlimited number of User Experiences, a physical instrument layer which allows for any given stimulus and measurement capability to be wrapped in such a manner as it can easily connect with any hardware system running the Platform and offer up services which can be abstracted to the user as a User Experience through the Virtual Instrument Layer, and Test Executable Layer which separates the actual test execution from the system software allowing for custom and user-defined test programs to be developed.
In an exemplary embodiment, the Platform is a hardware agnostic entity, thus the Platform can run on any hardware and Operation System base which provides the minimum services required to run. In an exemplary embodiment, the minimum services may comprise an ARM based single board computer based on NVIDIA Tegra 2 & 3, Freescale Vybrid and Intel/Marvell XScale (PXA270, PXA300, PXA310, PXA320) such as the Toradex Colibri Computer Module, supporting hardware to provide wired and wireless connectivity, and a NAND Flash memory.
Therefore, the Platform can reside on systems built upon many Operating Systems and hardware comprising a microprocessor core and sufficient memory to support the Platform. Exemplary embodiments of Operating Systems comprise Android, Linux, Windows, etc.
In an exemplary embodiment, the Platform is an application agnostic entity, thus the Platform is not tied to any given stimulus and measurement capability or any given user experience. As such, an exemplary embodiment of the Platform is not limited to test and measurement systems and could reside on any minimally capable hardware system and support any hardware or software component which can be wrapped in a Physical Instrument Layer and support a user experience for a Physical Instrument as embodied in a Virtual Instrument Layer. In an exemplary embodiment, a physical instrument layer comprises a radio. In a second exemplary embodiment, the physical instrument layer comprises test equipment. In an exemplary embodiment, a complete functioning system made up of one or more Virtual Instruments, one or more Physical Instruments, and a Test Executable can be established on said hardware. Exemplary embodiments of hardware may comprise an iPad, a Nexus 7, or a Lenovo x230.
In an exemplary embodiment, the Platform is hardware agnostic, which allows the Platform to reside on a plurality of hardware systems at one time, wherein each of the hardware systems comprise a minimum processing and memory capability to support the Platform. In an exemplary embodiment, the Virtual Instrument Layer, the Physical Instrument Layer, and the Test Executable Layer are not tightly integrated, which allows each layer to reside on hardware systems that are separate from the Platform.
In an exemplary embodiment, the Virtual Instrument Layer is not tightly coupled with a Physical Instrument, thus more than one Virtual Instrument abstraction can run for a given Physical Instrument. This enables the functionality of a given Physical Instrument to be exposed in multiple different manners providing a greater flexibility of end-usage. For example, a Physical Instrument comprises an LED. The LED can be exposed as a Virtual Instrument which abstracts the LED to the user. In an exemplary embodiment, the LED may be abstracted to the user as a Flashlight (the LED turns on and off), a Random Light Pattern Maker, and a Morse Code Visual Signaling device. In an exemplary embodiment, each Virtual Instrument can reside on the hardware system simultaneously and can run simultaneously if the given desired application implementation demands or benefits from simultaneous execution.
In an exemplary embodiment, the Physical Instrument is not tightly coupled with the Platform, thus a plurality of hardware and software capabilities can exist simultaneously and run simultaneously within the given hardware system. For example, an Optical Light Source Physical Instrument, an Optical Power Meter Physical Instrument, and a Copper Power Meter Physical Instrument can be simultaneously supported on a given complete system running the Platform and provide the user the capability to test an optical-copper link from end-to-end. In an exemplary embodiment, a complete system may comprise the minimum system to support the Platform as referenced above, stimulus and measurement hardware for each of the Physical Instruments, and either hardwired or wireless connectivity between the hardware system hosting the Platform, wherein the hardware systems embodies the stimulus and measurement (such as a OPM Module, OLS Module, CPM Module).
In an exemplary embodiment, a complete system may comprise a Lenovo X320 laptop running the Platform. In an exemplary embodiment, three independent modules (OPM, OLS, CPM) each have their own battery, their own onboard processing, and their own wireless link. In an exemplary embodiment, each module is wirelessly connected to the laptop via 802.11g. In an exemplary embodiment, the Physical Instrument Driver for each module would be executed on the Lenovo Laptop. In an exemplary embodiment, different Virtual Instrument Drivers would run on the laptop and interface with the Platform. The above system would give a complete test system buildable upon any laptop and infinitely configurable with Physical Instrument Modules and Virtual Instruments.
In an exemplary embodiment, a Virtual Instrument is not tightly coupled with the Physical Instrument, thus a Virtual Instrument can be developed which interfaces with one or more Physical Instruments. In an exemplary embodiment, the complete system described above can expose an OLS Virtual Instrument, an OPM Virtual Instrument, and a CPM Virtual Instrument simultaneously, or a single Virtual Instrument for a Fiber-Copper Link Tester can be exposed which wrappers all three Physical Instruments into a single application.
In an exemplary embodiment, the Platform layer is hardware agnostic and the Physical and Virtual Instrument layers are not tightly coupled, thus the communication protocol between said pieces is flexible and is defined only for a given complete system incarnation and meeting the minimum requirements of the Physical Instrument embodiment. In other words, as communication technology improves (copper, Bluetooth, Wifi, etc) the complete system is unlimited by the actual architecture implementation through the “Platform” and “Virtual Instrument” layer.
