Basic traffic analysis
● Customizing the settings of speedtest.net so you can run a speed test between your
location and a geolocation that is closest to the Office 365 data center.
In this example, our speed test results reveal that we have 20.86 Mbps available in
download speed and 3.74 Mbps available in upload speed. The 10 ms ping result is the latency
of the network. In the next section, where we calculate the network demands of Office 365
services, we can determine whether you have adequate network performance to support
a good experience for your users when you migrate them to Office 365. If not, we might
need to remediate our network performance by increasing bandwidth or reducing network
Collecting network statistics
Network performance varies throughout the day for a variety of reasons. For example,
if many users log in at 9:00 A.M. in the morning to start their workday, the network is
more congested at that time. It might taper off significantly at lunch time and around
quitting time at 5:00 P.M. If your organization is using commercial broadband, other ISP
customers also might contribute to network congestion at different times of the day.
Therefore, it is a good idea to conduct your speed test exercise during different times
of the day, especially during known peak times, so that you can get an average of your
network performance as well as the level of peak demand. If you have intelligent
network gear in your organization, most of this information can be collected automatically
as part of the network gear’s capabilities, or you might use tools like a Fluke meter to
collect network statistics. The extra effort and time you put in to diligently baseline your
network utilization will help you be more accurate in predicting the experience with
Office 365 and thus help you determine whether network remediation is required.
Basic traffic analysis
You should have some basic traffic information about your organization. For example, you
should have some idea as to the types of traffic on your network and how much bandwidth
each type of traffic is consuming. Most enterprise networks should have undergone at least
one Quality of Service (QoS) analysis exercise that would yield the information you require.
From the earlier exercise, you should also have an idea of your Internet speed.
Let us go through a basic traffic analysis so we can demonstrate how to create a baseline
idea of the amount of bandwidth you would need for your environment. Figure 2-15 shows
a network diagram that depicts the types of network traffic found in the different network
