Automatic Bandwidth Adjustment
As you've seen, MPLS TE tunnels can be configured to reserve bandwidth. But in everything you've seen so far, reservations require manual intervention to change. What happens if the traffic patterns in your network change several times during the day? One way to handle this situation is to use an offline tool to figure out how much bandwidth to give each tunnel and to send new configurations to your routers with the new configuration information. See Chapter 9 for more on the issues involved.
Offline tunnel calculation has a decided advantage in that you can also use this offline tool to calculate the paths your TE LSPs flow over, which leads to a more efficient use of bandwidth. However, an offline tool is a lot ...
