Equivalent Capacity And Its Application To Bandwidth Allocation In High-Speed Networks, Roch A. Guérin, Hamid Ahmadi, Mahmoud Naghshineh Sep 1991

Equivalent Capacity And Its Application To Bandwidth Allocation In High-Speed Networks, Roch A. Guérin, Hamid Ahmadi, Mahmoud Naghshineh

Departmental Papers (ESE)

High-speed fast-packet-switched network architectures are capable of supporting a wide range of connections with different bandwidth requirements and traffic characteristics. While this environment provides increased flexibility in supporting various services, its dynamic nature poses difficult traffic control problems when trying to achieve efficient use of network resources. One such a problem is the issue of bandwidth management and allocation. Because of the statistical multiplexing of all connections at the physical layer and the variations of connections bit rate, it is important to characterize, for a given Grade-Of-Service (GOS), both the effective bandwidth requirement of a single connection and the aggregate ...

Teaching In A Virtual Classroom : Volume 2 Of A Virtual Classroom On Eies : Final Evaluation Report, Computerized Conferencing & Communications Center, Starr Roxanne Hiltz

Computerized Conferencing and Communications Center Reports

A Virtual Classroom is a teaching and learning environment located within a computer-mediated communication system. As a teaching environment, it provides a set of tools, strengths, and limitations which are available to an instructor for delivering course materials and structuring learning experiences. Its characteristics are merely potentials, just as the empty classroom with its chalkboards and desks awaits the efforts and creativity of the instructor and the students to make it "come alive."

This is the second volume of the final research report on experiences with the prototype of a Virtual Classroom system constructed and operated on EIES, the Electronic ...

Moderating Online Conferences, Revised Manuscript, Computerized Conferencing & Communications Center, Elaine B. Kerr Jan 1986

Moderating Online Conferences, Revised Manuscript, Computerized Conferencing & Communications Center, Elaine B. Kerr

Computerized Conferencing and Communications Center Reports

While considerable lore has accumulated about effective leadership techniques for groups interacting electronically, until now it has not been systematically presented. This material is culled from the experiences of those who have moderated past online conferences, the knowledge common to the EIES User Consultants, and observed behavior from thousands of conferences convened on EIES in the past. While this is a system-specific guide, the general principles ought to be generalizable to other systems, with different structures for group discussion.

Integrating Working At Home With Information Systems Management, Computerized Conferencing & Communications Center, Joseph C. Schuh Nov 1985

Integrating Working At Home With Information Systems Management, Computerized Conferencing & Communications Center, Joseph C. Schuh

Computerized Conferencing and Communications Center Reports

The history of computerization has its origin in the automation of manual processes - searching out the segments that could be put on a computer. The intended result was that the entire job would be done faster and cheaper. Thus, current computer-based information systems tend to make more efficient use of computers than people. The management function, on the other hand, often seems to focus on competitive skills and salesmanship rather than on the ability to attract and hold talented people. But, such impersonal factors that have driven management practices are changing. There has been a complete reversal in the relative ...

Determinants Of Acceptance Of Computer Mediated Communication System, Computerized Conferencing & Communications Center, Starr Roxanne Hiltz, Elaine B. Kerr, Kenneth Johnson, Murray Turoff

Computerized Conferencing and Communications Center Reports

Acceptance of Computer-Mediated communication Systems (CMCS) by managers and professionals corresponds to its incorporation into their daily patterns of communication and work. Acceptance includes at least three inter-related dimensions: amount of use, subjective satisfaction with the process of using the system, and a perception that system use has positive impacts upon productivity.

Pre-use and follow-up questionnaires were distributed to 150- 250 new users of four different CMCS. Three are conferencing systems, designed to support "group work." They differ in terms of comprehensiveness or complexity of design, and size and nature of the user communities; COM/KOM, a Swedish system with ...

The Evolution Of A Tailored Communications Structure : The Topics System, Computerized Conferencing & Communications Center, Peter Johnson-Lenz, Trudy Johnson-Lenz

Computerized Conferencing and Communications Center Reports

A computer-based human communication system should be designed for people's use, in response to their perceived needs and communications styles; no single system can meet the needs of all groups and individuals. It might seem that a general electronic mail or computerized conferencing system with a standard set of features should be able to meet most communications needs, in much the same way that the telephone system meets the needs of a wide range of users. However, there are many communications structures found in everyday life, ranging from one-to-many news broadcasts, to the many-to-many patterns of town meetings, from ...
