Claim 0:
1. A method of increasing efficiency in a backbone network for network traffic, the method comprising:
identifying multiple source devices having network tunnels to a destination device through the backbone network;
determining transmission rates of packets through the network tunnels by sampling packets passing through one or more network switches that are within a first of the network tunnels;
determining a number of hops through each of the network tunnels;
calculating an efficiency of the backbone network using a ratio including the transmission rates and the number of hops, wherein the calculating of efficiency further includes different weights applied to each network tunnel; and
based upon the calculated efficiency, modifying the first network tunnel by reducing the number of hops forming the first tunnel and by configuring a cache near or at the destination.
