Abstract
In this thesis, it is required to design and study a
Terminal-Oriented-Computer network which connects the
governorates in the Arab Republic of Egypt, in the sense of
satisfying the needs of anyone requesting service from
a central facility located in Cairo. To realize this goal
the governorates are provided with many term~nals distributed
over a number of centers proportional to the population
of the governorate.
This network should ensure sm~ll time-delay as well as
low cost. To make the design as systematic as possible, we’ve
divided our study into three phases, each one composed of
a group of programs which perform a determined job:
I.Topological design: to obtain the network joining the
governorates in the shortest possible paths, realizing thus
some measure of cost saving. Increasing the number of paths
increases reliability such that when anyone of them fails
a small number of governorates will be disconnected.
2.Modelling the network: to acquire an accurate evaluation
of the time-delay, buffer size and cost of the network obtained
from the previous step, and to study the effect of changing
the line capacity, on the above mentioned parameters.
3.Capacity assignment: to select from the set of capacities
used in the study of the previous step, those which provide
each of the obtained networks,with its own optimum time-delay/
cost characteristics.
In our study, we have designed many networks to provide
variable choices of time-delay, reliability and cost.
