Networks: Between Markets and Hierarchies

Abstract: Summary Interorganizational networks generally have been discussed in the context of nonprofit agencies. Providing an alternative between the open market and the internalization of activity the network potentially may be even more important in business. This is especially true in international operations and in industrial and services marketing. Involving technology transfer, information exchange, accounting and finance as well as marketing, network management calls for a holistic approach. To serve as an engine of growth the network also requires strategic planning both at the overall level and in memberfirms.

Managing computing resources in intranets: an electronic commerce perspective

Abstract: Intra-organizational networks (intranets) are increasingly being developed for information sharing and collaborative work in geographically dispersed organizations. However, organizations are increasingly realizing that having an intranet in itself may not provide expected increase in productivity and benefits. Intranet resources have to be managed appropriately and with organizational goals in mind for intranets to be a meaningful part of organizational environment. In this paper we provide a framework to manage the resources in the intranets using the concepts of electronic commerce. Specifically, we propose the creation of an electronic organizational unit, intranet Resource Management Unit (iRMU), that manages user requests using a dynamic priority pricing approach. The iRMU integrates a dynamic priority pricing approach with the concepts of topology management, security management, and software-agents based service construction to create a comprehensive resource management environment. The contribution of this paper is to provide a framework that integrates existing technological base with economic pricing approaches to create an economics-embedded intranet resource management approach.

SNA directions—a 1985 perspective

Abstract: Since its announcement in 1974, SNA has evolved in terms of its functional content, configurational flexibility, and network management services. This paper briefly traces this progress to the present, and examines the more recent advances in greater detail. We then discuss known requirements for enhanced application and transaction services, for additional provisions for very large networks, for con­ tinuing exploitation of small-system and transmission media advances, for inclusion of additional management capabilities, and for further accommodation of network standards, all of which will shape future SNA developments.

Achieving Network Availability in a Multilayered Protocol Environment

Abstract: The software/hardware is available now to quickly construct very large networks. These networks contain various layers of connectivity with the possibility of different vendors providing each layer. Each layer may have its own means of operator management and control. The growth of these networks is starting to outstrip the ability of network operators to effectively recognize and attack problems. Future networking with independent microcomputers provide even fewer tools for network support personnel. What should network management software provide the operator in a multilayered multivendor environment, and what role do network protocols play in solving the problems they created? The author will he expressing his own opinion based on his experience with a large IBM SNA network (28 hosts) connected through a privately owned X.25 network.

Method for operating network maintenance address

Abstract: PURPOSE:To grasp easily the existing location of a faulty station in a network at fault by generating identification information representing the physical connecting location of a general station by the station in connecting the station to the network and sending the message including the information to a management station. CONSTITUTION:The management station 3 of the network consists of a fault report communication frame 4 and a location represented by a local identifier. When a station (1-K) detects a fault, a console key of the station is used and generation of a fault is informed to the management station 3 by using a fault report frame 4. The frame 4 is a network management frame where FC 11 is set as '10000000', information of the location 5-P is stored by using a local identifier to an LA 20 and fault information is stored in an MI 21. The management station 3 uses the LA 20 that a fault exists in the station (1-K) in the location 5-P and then, for example, the maintenance personnel visits the location 5-P for the maintenance of the station (1-K). Thus, the maintenance efficiency is improved.

Network design consideration of a satellite-based mobile communications system

Abstract: Technical considerations for the Mobile Satellite Experiment (MSAT-X), the ground segment testbed for the low-cost spectral efficient satellite-based mobile communications technologies being developed for the 1990's, are discussed. The Network Management Center contains a flexible resource sharing algorithm, the Demand Assigned Multiple Access scheme, which partitions the satellite transponder bandwidth among voice, data, and request channels. Satellite use of multiple UHF beams permits frequency reuse. The backhaul communications and the Telemetry, Tracking and Control traffic are provided through a single full-coverage SHF beam. Mobile Terminals communicate with the satellite using UHF. All communications including SHF-SHF between Base Stations and/or Gateways, are routed through the satellite. Because MSAT-X is an experimental network, higher level network protocols (which are service-specific) will be developed only to test the operation of the lowest three levels, the physical, data link, and network layers.

Use of toleranced ‘cost’ functions for circuit routing in complex communications networks

Abstract: A network routing algorithm is described which allows multiple routing options, from any one source to all destinations, to be defined with virtually the same computational load as the single ‘cheapest’ route to all destinations. It also presents the result in a manner well suited to further editing by the human network designer or manager. The algorithm is founded on the nature of the relevant cost functions and is supported by a discussion of the distinct types of cost functions appropriate to different applications.

Local Area Network Standards and Guidelines for U.S. Marine Corps Applications.

Abstract: : This thesis highlights the need for specific guidance and standards in the U.S. Marine Corps local area network (LAN) specification and selection process. Media, topologies, components access methods, protocols, standards and other technologies are used to characterize the current technical environment. A strategy for LAN specification and selection is presented. This strategy stresses top-down, user requirement, protocol performance oriented techniques vice the bottom-up technical design selection oriented techniques in use today. Thorough documentation of user requirements, higher-level services, higher-level protocols, and an information and networking strategy along with other considerations like facilities/support, expected general performance, network management, and security is the method proposed for preparation of a complete specification document. A centrally coordinated U.S. Marine Corps specification and design database is also propose to insure future interoperability, connectivity, and support.
