Claim 8:
9. 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, wherein the calculation of the efficiency includes using a formula including the following: efficiency=y/yweighted, wherein y is a summation of transmission rates for multiple streams of network traffic from different sources to the destination and yweighted is a multiplication of the number of hops and the transmission rates; and
based upon the calculated efficiency, modifying the first network tunnel by reducing the number of hops forming the first tunnel.
