The purpose of the next few pages is to provide the main information and guidelines
to help you answer the second point. Given that the performance of an Ethernet
architecture is linked to many parameters, these pages do not provide all the
information needed to calculate the network performance. Their aim is to focus on
the guidelines for evaluating the network load so as to design an Ethernet network
that meets the demands of the applications. Calculating the load involves many
parameters, so only the main guidelines will be presented here.
When evaluating the load on an Ethernet network, the communication services of
the peripheral devices connected to the network need to be calculated. Because of
the outstanding performance of the Ethernet network, the load is often less than the
Ethernet network limits and does not significantly affect the application response
time. This is due to the high speed of the Ethernet network,which reduces the
network transaction time to less than 10% of the total application response time. To
help ensure a low network load and to avoid large theoretical calculations, we
strongly recommend that you separate the collision domain so as to limit the network
load, using only switched network (a tree, star or daisy-chain topology).
