  • Distributed computing with high-speed optical networks

    Publication Year: 1993, Page(s):8 - 18
    Cited by:  Papers (34)  |  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1966 KB)

    An environment that uses wavelength division multiplexing techniques and optical switching and processing to provide large bandwidths, short delays, and multiple data streams for distributed processing is described. The focus is on the interrelationship between application needs and network services. The system level, a conceptual layer designed to bridge the gap between application requirements a...

    Several hardware-based techniques that support checkpoint and rollback recovery are presented. The focus is on hardware schemes for uniprocessors, shared-memory multiprocessors, and distributed virtual-memory systems. A taxonomy for processor and memory techniques based on the memory hierarchy is presented. This provides a basis for understanding subtle differences among the various schemes. Proce...

    A framework providing a basis for comparing and evaluating software development methods (SDMs), which are systems of technical procedures and notational conventions for the organized construction of software-based systems, is presented. Using the framework, practitioners and methodologists can describe and rate an SDM's support for 21 properties. The application of the framework to two examples, O... View full abstract»

  • Object-oriented database management systems: evolution and performance issues

    Publication Year: 1993, Page(s):48 - 58
    Cited by:  Papers (26)

    Several research prototypes and commercial object-oriented database management systems (DBMSs) that emphasize the representation and manipulation of complex objects are reviewed. It is argued that clustering and buffering schemes tailored to typical complex object operations offer the best near-term means of improving the performance of databases and that research in clustering and buffering shoul...

  • A survey of wormhole routing techniques in direct networks

    Publication Year: 1993, Page(s):62 - 76
    Cited by:  Papers (780)  |  Patents (11)

    Several research contributions and commercial ventures related to wormhole routing, a switching technique used in direct networks, are discussed. The properties of direct networks are reviewed, and the operation and characteristics of wormhole routing are discussed in detail. By its nature, wormhole routing is particularly susceptible to deadlock situations, in which two or more packets may block ... View full abstract»

    Virtual reality (VR) presents a synthetically generated environment to the user through visual, auditory, and other stimuli. A VR systems's head-mounted display, stereo graphics, and direct manipulation in three dimensions are outlined. Early work in VR and major technological hurdles in the areas of tracking, display, image generation, and software support are reviewed. Research directions and po... View full abstract»

    Nonimmersive virtual reality (VR), which places the user in a 3D environment that can be directly manipulated with a conventional graphics workstation using a monitor, a keyboard; and a mouse, is discussed. The scene is displayed with the same 3D depth cues used in immersive VR: perspective view, hidden-surface elimination, color, texture, lighting, shading and shadows. As in immersive VR, animati...

    A virtual environment is a generic, relatively low-cost real-time interactive simulation. It is shown that the US military has been a primary supporter of real-time simulation for more than 60 years, ever since the development of the Link Flight Instrument Trainer in the late 1930s. The development of flight simulation systems and head-mounted displays are reviewed. The use of virtual environments... View full abstract»

    The International Organization for Standardization's (ISO's) standard for the exchange of product-model data (STEP) is discussed. The goal of this standard, officially named ISO 10303, is to facilitate the computer-readable exchange of the total information used to define an industrial product. As a standard method for digital product definition. STEP will support communications among heterogeneou... View full abstract»
