1. A method for analyzing routes to a destination address space, comprising:
- identifying a plurality of paths, each path beginning at a different source and terminating at a common destination address space;
identifying a plurality of nodes for each of the plurality of paths;
identifying at least one convergence point between at least two of the paths, wherein the convergence point is a common node for the at least two paths, said at least two paths being non-diverse from the convergence point to the destination address space;
associating the convergence point with the destination address space;
determining a path performance for each of the at least two paths, wherein the path performance is based on a path performance from the source of each path to the convergence point; and
analyzing the at least two paths to the destination address space.

Abstract
The present invention uses proxy points for measuring different routes to a destination address space. Multiple paths to the desired destination address space are identified. Each path begins at a source and terminates at the destination address space. Proxy points are identified for each path and are associated with a point between the source and the destination address space. Measurements of the path performance from each source to the appropriate proxy point are compared to determine an optimum route.
