VPN Capacity Planning
VPN Traffic Explorer lets service providers ensure
that their network will continue to meet growing
customer needs by predicting future capacity requirements.
Network engineers can analyze traffic trends on
every link in the network, projecting not only
future traffic levels, but easily determining
when user-specified thresholds will be reached.
Projections can be based on total link traffic,
thereby anticipating and helping avoid network
congestion, or by CoS, assuring that the network
is properly engineered for critical traffic, such
as voice or video. Traffic projections can be
calculated using a variety of models (e.g. linear,
exponential) to best fit historical trends. When
capacity increases are required, network managers
can justify upgrades since they’ll know which
customers contributed to the growth.
The Capacity planning report (above) projects
historical traffic utilization trends to either
a utilization threshold or to a future point in
time. Once the trending analysis has been run,
engineers can examine per link, CoS and customer
traffic levels to ensure SLA compliance
