Systems Management is emerging as the predominant area for computer science in the enterprise, with studies showing that the bulk (up to 80%) of an enterprise IT budget is spent on management/operational issues and is the largest piece of the expenditure. This textbook provides an overview of the field of computer systems and network management. Systems management courses are being taught in different graduate and undergraduate computer science programs, but there are no good books with a comprehensive overview of the subject. This text book will provide content appropriate for either an undergraduate course (junior or senior year) or a graduate course in systems management.

Delivers the hard information the reader needs to assess network options for the 1990s. It describes how networks are configured, what your options are in the multivendor environment, and how you can get the most efficient and effective network solutions with limited communications budgets.

Abstract: "The increasing complexity and heterogeneity of modern networks has pushed industry and research towards a single and consistent way of managing networks. The effort to define a single industry-standard API for network management basically failed because it did not address aspects like complexity and ease of programming. Recently, a common approach is to map established network management standards into another object model, often based on the emerging Corba standard. Unfortunately even this approach has shown many drawbacks related primarily to the significant amount of code that has to be linked with the final application and to the many limitations and imperfections of the mapping itself. This paper describes a new approach to inter-domain management that attempts to overcome the limitations of current solutions. The goal is to allow people to write hybrid CMIP and SNMP-based network management applications using a single and simple object model. Relevant characteristics of this approach are that it is light, extensible, object-oriented, language- neutral, built upon software-components, string-syntax based and Internet- ready. This demonstrates that it is feasible to implement simple and light applications for inter-domain management without the need for expensive or complex technologies."

Presents a distillation of informed analysis from a wide spectrum of international sources on likely networking trends. Reviews the various aspects of networking and their potential, problems with data transmission, and developments in computer architectures and protocols. Analyses of new applications are included, and there are insights into the effects these will have on organizations, management and network operation.

Try to imagine a railway network that did not check its rolling stock, track, and signals whenever a failure occurred, or only discovered the whereabouts of its lo comotives and carriages during annual stock taking. Just imagine a railway that kept its trains waiting because there were no available locomotives. Similar thoughts could apply to any transport network of trucks, buses, or taxis covering a wide geographical area. It is quite clear that the quality of service and safety, and the cost efficiency of any network depend on the effective and timely man agement of network resources. The same is true of telecommunications networks. For a long time now, telecom munications networks have been designed and built with remote monitoring and control devices. The very dimensions of networks and the need to intervene rap idly in the event of an incident made these devices imperative. On the other hand, the means of measuring quality of service did not appear till much later. Data transmission networks developed during the 1970s were often designed without any network management features. The technical traditions of the world of information technology had been forged on small systems with just a few dozen terminals spread over a small area. At the time, the extension of networks to cover wide geographical areas was not perceived as a change of dimension.
