Thomas Raphael Malarkey; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| During the 1980s we will continue to see an increased use of distributed computer networks. Although network usage has been found to be effective in a wide variety of applications, continued network expansion heightens the need for effective management to achieve optimum performance, reliability, and security of network operation. Advances in network management have not kept pace with the problems that arise in network operation. The Community On-Line Intelligence System ... |

| An Investigation of Access Area Engineering Methods for AUTOVON |
AUG 1981 |
|
| Authors:
M. J. Fischer; DEFENSE COMMUNICATIONS ENGINEERING CENTER RESTON VA
|
| In this technical note we compare both qualitatively and quantitatively the two methods (AT&T and DCA's) being used to perform access line engineering on the current AUTOVON network. The DCA method was found to be superior but had one deficiency. We then present a method which overcomes this deficiency and performs better than the other two. (Author) |

| On the Placement and Sizing of Conference Directors in the CONUS AUTOVON. |
Nov-1980 |
|
| Authors:
M J Fischer; G W Swinsky; DEFENSE COMMUNICATIONS ENGINEERING CENTER RESTON VA
|
| In this technical note we report on the study that was conducted in answering the following questions: How many Conference Directors should there be in CONUS AUTOVON and where should they be located? What is the required port sizing to meet the conference traffic requirements? What is the impact of accommodating the conferencing traffic requirements on CONUS AUTOVON? The analytic and computer methods used to answer these questions, as well ... |

| Authors:
D. Calabrese; M. Fischer; B. Hoiem; E. Kaiser; DEFENSE COMMUNICATIONS ENGINEERING CENTER RESTON VA
|
| In order to evaluate the potential impact of facsimile-imagery service upon the current and future Automatic Voice Network (AUTOVON) and to reduce the time required to perform worldwide AUTOVON Flash Non-Blocking (FNB) Studies, the capability of the DCEC Voice Network Model has been extended from a single class traffic model to a two class traffic model. As in the AUTOVON system, one class of traffic can preempt the other class ... |

| This report reviews technological developments in commercial telecommunications in switching, terrestrial transmission and satellite communications. Based on this assessment, six alternatives were postulated and analyzed to gain a better understanding of the fundamental structure, relationships and sensitivities of cost, survivability and performance considerations. The study indicates that there is a potential for large savings by exploiting the technological improvements in commercial communications. Although the uncertainties are very large for the ... |
