MPLS 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
