Sylor 1 Editor's Introduction The paper by Bill Hawe, Mark Kempf, and AI Kirby reports how studies of potential new broad­ band products led to the development of the Extended LAN Architecture. The design of the LANBridge 100, the first product incorporating that architecture, is described, along with the trade-offs made to achieve high performance. The speed of communication between terminals and systems depends on how they are connected. Bruce Mann, Colin Strutt, and Mark Kempf explain how they developed the LAT protocol to connect terminals to hosts on an Ethernet.

  • Networking Standards Mark Davies, Digital Equipment Corporation
    N92-12499 Networking Standards Mark Davies, Digital Equipment Corporation ABSTRACT The enterprise network is currently a multivendor environment consisting of many defacto and proprietary standards. During the 1990s, these networks will evolve towards networks which are based on international standards in both the LAN and WAN space. Also, you can expect to see the higher level functions and applications begin the same transition. The Open Network Advantage Market Requirements OPEN NETWORKS!!! Multi-protocol, multi-platform, multi-vendor networks working together International AND defacto standards Effortless communications within and between enter- prises Ability to move to standards at own pace What is an Open System? Defined as: A vendor-neutral computing environment: - compliant with International and defacto standards - permits system and network interoperability or software applications portability - includes consistency of data and human access - satisfies one or more of a business's functional requirements Standards Benefits from networks based on international and defacto standards o Vendor independence o Applications portability o Investment protection o Improved communications leading to increased productivity o Network flexibility 13DSDDED Network Architectures: DECnet, OSI, TCP/IP DECnet OS) IP Application Application Internet Applications Protocols Presentation DMA Session Control Session Transport Transport Transport (NSP) (TP 0,2,4) (TCP / UDP) Network Network Network (CLNS) (CLNS/CONS) (IP) Data Link Data Link Data Link
