Calculate network load with IP Trunk 3.01 (and later) traffic
Suppose the intranet has a topology as shown in Figure 25 "Calculate
network load with IP Trunk 3.01 (and later) traffic" (page 124) and a
prediction on the amount of traffic on a specific link, R4-R5, is required.
From the "
"IP Trunk 3.01 (and later) traffic engineering" (page 95) " section
and Traceroute measurements, the R4-R5 link is expected to support the
Santa Clara/Richardson, Santa Clara/Tokyo, and the Ottawa/Tokyo traffic
flows; the other IP Trunk 3.01 (and later) traffic flows do not route over
R4-R5. The summation of the three flows yields 93 CCS or 24 kbit/s as the
incremental traffic that R4-R5 will need to support.
To complete this exercise, total the traffic flow for every site pair to calculate
the load at each IP Trunk 3.01 (and later) endpoint.
Route Link Traffic Estimation
Routing information for all source-destination pairs must be recorded as
part of the network assessment. This is done using the Traceroute tool. An
example of the output is shown below.
