How to calculate the minimum required Internet channel?

Question

Computer networks

The organization is located in two buildings. The width of the Internet channel to each of which is 5 Mb / s, between the buildings the point-to-point connection is also 5 Mb / s. The network load is small: SMEV, VPN with the treasury, VoIP-telephony, videoconferencing via open and closed channels (not running simultaneously), email and document management on "DocsVision 4.5", up to 100 workstations. How to calculate network peak load?

Answer 1

the most traffic-consuming connection is selected, multiplied by the number of such connections, multiplied by 14-20% - the channel width in megabits is obtained,
further can be multiplied by the reservation factor

Answer 2

If there is a server with the ability to monitor the network, or some kind of traffic inspector, you first need to look at the statistics of open / unopened pages, resource response time and other information. From experience I can say that video conferencing can more than capture all the resources of the channel). Based on the results of collecting such statistics, it will be easier for you to focus on the needs of the organization and calculate the content weight * number of users using a simple formula: time +% 20 growth of the organization's needs as soon as everything is fine (no matter how much you feed ...).

Answer 3

by observing and calculating the peak load. the rest is from the evil one. user user strife so to speak
