    This paper deals with the implementation of an electrical-optical interface for data transmission among PCs, via wireless in-house IR radiation, using commercial and available devices. Data transmission is achieved using the CSMA/CD IEEE 802.3 standard. The main advantages of this system are lower costs (no cabling required), mobility and no interference with neighbor networks. These advantages, t... View full abstract»

    One of the challenges in the interconnection of LANs and MANs to ATM is the support of connectionless traffic in the ATM network. Several solutions have been proposed. A popular strategy seems to be that of maintaining a `thin' (i.e. low bandwidth) VP (virtual path) between each pair of gateways, and of requesting more bandwidth whenever a burst comes in from the LAN or MAN. Unfortunately, this st... View full abstract»

    The authors consider a front end system consisting of a number of source stations generating LAN traffic; a queue to accommodate the transmission delays; and a number of ping/pong buffers, one for each LAN connection, served by the internal bus of the front-end processor. An incoming frame segment at a front end interface is assumed to be lost if there is no buffer available to store the segment. ... View full abstract»

    The paper describes the `Stuttgart Tetrahedron' and how it is distributed under the `ideal' campus situation. The need for knowledge sharing and cooperation between researchers in strategic fields is shown to be the main driving force for distributing such tetrahedrons over Germany and necessarily over Europe. The Stuttgart VBN projects and the MAN field trial are described within this context. Th... View full abstract»

    Several transport protocols have been proposed for use in the Internet. The specifications of these protocols are based on the assumption that a general purpose transport protocol can be designed to be used by a variety of applications, including time-constrained applications. A widespread consensus among the researchers is that a general purpose transport protocol is not optimized for any applica... View full abstract»

    ATM (asynchronous transfer mode) is an international telecommunications standard designed for broadband integrated services; it is also well-suited for use within local-area networks. ATM LANs can provide the networking support needed for multimedia communication at rates of 100 Mbits/sec and higher. The authors first analyze the protocol processing required to handle ATM communication. Based on t... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (512 KB)

    Bridges and routers are used to interconnect local area networks (LANs). The performance of these devices is important since they can become bottlenecks in large multi-segment networks. Performance metrics and a test methodology for bridges and routers have not been standardized. Performance data reported by vendors is not applicable to the actual scenarios encountered in an operational network. H... View full abstract»

    Transparency is a popular feature in a distributed system where users can access any local or remote resources just as if they were local. The paper proposes a protocol which combines the features of transparency and shortest path. The result is a bridge which supports self learning and distributed routing computation. Since this bridge has all routing facilities as a router, it is called brouter ... View full abstract»

    In a distributed computing environment, a testbed is built to investigate topology learning behaviors of bridges for LAN interconnection. It is flexible to configure on any networked computing facility and thus serves as an environment for rapid prototyping of bridge systems. Unlike a pure simulator, the testbed employs distributed computing in itself so that the parallelism embedded in protocols ... View full abstract»

    The US Navy is selecting a et of local area networking standards, under the name SAFENET, for use on tactical platforms. The set of standards incorporate the FDDI local area network (LAN) at the physical and data link layers. The SAFENET group has taken an FDDI feature (the hold policy option) and used it as the basis of a data path hop (or switch) capability. The paper provides a discussion of FD... View full abstract»

  • Temperature-related changes in dielectric constant and dissipation factor of insulations increase attenuation in data cables used in building plenums

    Publication Year: 1991, Page(s):74 - 79
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (204 KB)

    Local area network performance can deteriorate when high temperatures cause cable attenuation to increase. This problem can be prevented by careful selection of insulating materials. Dissipation factor and dielectric constant for FEP, PVC, and ECTFE were measured at frequencies from 1 kHz to 300 MHz at 20°C and 60°C. Increases in values for these properties can be related to increases in c... View full abstract»

    This paper treats characterization of ATM traffic. As the connection acceptance control, the policing and last but not least the terminal equipment are concerned with traffic characterization, this issue is of special importance.

    This paper presents a data transmission technique using infrared pulse modulation which differs from usual schemes such as FSK or bi-phase PPM. It is based on HDLC-like frames including the `bit stuffing' mechanism. HDLC is basically a synchronous transmission oriented protocol, used here however to transmit an asynchronous flow of characters. The automatically inserted `flags' maintain a `data ca...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (680 KB)

    Studies have shown that earlier versions of the distributed queue dual bus (DQDB) exhibited asymmetric segment access delay under heavy loads. A bandwidth balancing (BWB) mechanism was subsequently adopted to improve the access delay characteristics of DQDB. This mechanism, however, does not effectively support multiple levels of priority that DQDB may need in order to provide new services to the ... View full abstract»

    A pairwise switch-connection mechanism for interconnecting multiple token passing ring networks is proposed. The total number of internetwork packet store-and-forwards occurring at the bridges can be significantly reduced under the new switching method.

    Presents a fault-tolerant bridging scheme for interconnecting multiple LANs. Fault tolerance is built by linking a LAN to two bridge ports located on two different processing elements, respectively. Two load-partitioning schemes are developed to prevent multiple copies of an arriving frame. A static partitioning scheme requires little hardware or software augmentation. However, the load may not be... View full abstract»
