This book covers the management of telecommunication networks of all types, including PSTNs, LANs, WANs and data networks. The perspective is broad, making the volume useful as a tutorial introduction and working reference.
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.
This book provides you with an accessible overview of network management covering management not just of networks themselves but also of services running over those networks. It also explains the different technologies that are used in network management and how they relate to each other.--[book cover].
Three speakers at the Second Workshop on Network Management and Control nostalgically remembered the INTEROP Conference at which SNMP was able to interface even to CD players and toasters. We agreed this was indeed a major step forward in standards, but wondered if anyone noticed whether the toast was burned, let alone, would want to eat it. The assurance of the correct operation of practical systems under difficult environments emerged as the dominant theme of the workshop with growth, interoperability, performance, and scalability as the primary sub-themes. Perhaps this thrust is un surprising, since about half the 100 or so attendees were from industry, with a strong contingency of users. Indeed the technical program co-chairs, Shivendra Panwar of Polytechnic and Walter Johnston of NYNEX, took as their assignment the coverage of real problems and opportunities in industry. Nevertheless we take it as a real indication of progress in the field that the community is beginning to take for granted the availability of standards and even the ability to detect physical, link, and network-level faults and is now expecting diagnostics at higher levels as well as system-wide solutions.
Why getting results should be every nonprofit manager's first priority A nonprofit manager's fundamental job is to get results, sustained over time, rather than boost morale or promote staff development. This is a shift from the tenor of many management books, particularly in the nonprofit world. Managing to Change the World is designed to teach new and experienced nonprofit managers the fundamental skills of effective management, including: managing specific tasks and broader responsibilities; setting clear goals and holding people accountable to them; creating a results-oriented culture; hiring, developing, and retaining a staff of superstars. Offers nonprofit managers a clear guide to the most effective management skills Shows how to address performance problems, dismiss staffers who fall short, and the right way to exercising authority Gives guidance for managing time wisely and offers suggestions for staying in sync with your boss and managing up This important resource contains 41 resources and downloadable tools that can be implemented immediately.
For more than 20 years, Network World has been the premier provider of information, intelligence and insight for network and IT executives responsible for the digital nervous systems of large organizations. Readers are responsible for designing, implementing and managing the voice, data and video systems their companies use to support everything from business critical applications to employee collaboration and electronic commerce.
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.
Like the 120 volt standard for electricity, the appearance of standards in network management heralds new opportunities for creativity and achievement. As one example, within the framework of these evolving standards, consider a system of local area networks connecting computing equipment from different vendors. A bridge 1qc. k:8 up because of a transient caused by a repeater failure. The result is a massive disconnecHon of virtual circuits. What is the role of the manager and the network management system in solving the problem? How does the vendor implement the solution? How does the user use it? What measurements should be made? How should they be displayed? How much of the diagnosis and correction should be automated? How does the solution change with different hardware and software? In the IEEE Communications Magazine, I recently reported a timely illustration in the area of problems in fault management. At the workshop hotel, "I was waiting for a room assignment at the reception desk, when my attendant left the counter for a moment. Upon returning, he took one look at his screen and whined an accusatory question at everyone in sight, 'Who logged out my terminal?' Who indeed! It wasn't any of us. It was the system.
Network management refers to the activities, methods, procedures, and tools that pertain to the operation, administration, maintenance, and provisioning of networked systems, which includes controlling, planning, allocating, deploying, coordinating, and monitoring the resources of a network. This book brings all of the elements of network management together in a single volume, saving the reader the time and expense of making multiple purchases. It introduces network management, explains the basics, describes the protocols, and discusses advanced topics, by the best and brightest experts in the field. It is a quick and efficient way to bring valuable content together from leading experts in the field while creating a one-stop-shopping opportunity for customers to receive the information they would otherwise need to round up from separate sources.* Chapters contributed by recognized experts in the field cover theory and practice of network management, allowing the reader to develop a new level of knowledge and technical expertise. * This book's up-to-date coverage of network quality of service issues facilitates learning and lets the reader remain current and fully informed from multiple viewpoints.* Presents methods of analysis and problem-solving techniques, enhancing the reader's grasp of the material and ability to implement practical solutions.* Use of examples illustrate core network management concepts for enhanced comprehension.
Effective management of a communications network can be a difficult and costly activity, and even more so when the network crosses international borders. International network managers face a number of issues that are crucial to strategic decision-making, including the varying telecommunications regulations, operators, and services found within-as
