The Benefits of IP VPN Bursting

Written by on January 9, 2013

XO Communications recently announced that we now support bursting on our MPLS IP-VPN service.

Bursting can provide a real cost savings benefit to customers. First, it’s a solution for customers who don’t how much bandwidth they need at a given location. Bursting lets these customers add locations to their network at the lowest level of cost commitment.

Second, it is an ideal solution for customers who know that their bandwidth needs may spike much higher than normal due to, for example, seasonal traffic peaks. Bursting lets these customers commit to the least amount of bandwidth they need for continued use and pay for only what they use in excess of that amount.

Here’s an example of how it works:

A customer commits to 100 Mbps of bandwidth at a location. XO sets up their IP VPN port to handle bursting. That location can now burst traffic all the way up to 1 Gbps.

XO samples traffic leaving the port throughout the month. At the end of the month, billing is calculated for the:

  • Committed 100 Mbps port rate; plus the,
  • Sustained traffic rate in excess of the committed rate.

XO discards the top 5% of the traffic samples taken during the month. This eliminates any spurious or unusual traffic from the billing measurement.

If customers find that their sustained traffic is significantly higher than their committed data rate (in this case, 100 Mbps), they can increase their commitment and take advantage of lower prices at higher sustained data rates.

Bursting is a feature many customers have requested for the reasons noted above. Now, with its availability, XO is better able to meet our customers’ needs with increased flexibility in supporting their private data networks.
