Tunnel Sizing and Demand Sizing Overview


This chapter describes how to resize a network’s LSP tunnels based upon the measured traffic on the tunnel or to resize a network’s demands based upon the traffic load.


This feature requires both the MPLS-TE and the loadanalysis license. Please contact your Juniper representative for more information.

From the Report Manager, you can identify tunnels in the network where the planned tunnel bandwidth is greater than or less than the actual transported layer 3 traffic. For such cases, you may then wish to change those tunnels’ bandwidths to make sure that sufficient bandwidth is allocated to carry traffic to meet Service Level Agreements (SLAs). The Tunnel Sizing feature in IP/MPLSView provides an automated solution for resizing these tunnels.

For instructions on how to view or modify the tunnels in your network, see IP/MPLSView LSP Tunnels Overview, .
