MPLS VPN Network Modeling

VPN Traffic Explorer allows engineers to model network changes such as the growth of an individual customer or additions of new customer VPNs before they’re implemented, helping to ensure that service levels can be met in the core network once service changes are made. Routine maintenance changes and network reconfiguration can also be simulated in order to preventing outages from simple misconfigurations and even from network architecture errors that only become apparent when routing and traffic is altered. VPN Traffic Explorer can also simulate changes to an entire customer or the whole network’s traffic matrix, showing traffic volumes between every source/destination pair in the network. Before and after comparison reports allow for comprehensive and detailed analysis on all modeled changes. Since changes are simulated on an always up-to-date model of the network, engineers can be confident about the outcome of any planned maintenance operations or network upgrades.

The "Add VPN Customer" wizard prompts engineers to select the PE routers that will service the customer’s CE sites, specify the VPN topology (hub and spoke vs. full/partial-mesh) and PE to PE traffic volumes, then simulates the new customer’s traffic across all relevant links in the network
