Sample Optical Network Topology Files

The first topology comes from the DARPA CORONET Program on Dynamic Multi-Terabit Core Optical Networks
This topology is Approved for Public Release, Distribution Unlimited

The CORONET Global Network is a hypothetical fiber-optic backbone network developed for use in researching large-scale DWDM networks. The location and connectivity of the nodes mimics existing networks but is not intended to characterize actual nodes in use today.

60-Node Network Derived from the CORONET CONUS Topology

The CORONET topology was specifically designed to be capable of providing a high degree of protection. For example, four completely link-diverse cross-continental paths exist in this network, which is not a common feature in US carrier networks. The 60-Node network shown below is somewhat more representative of current major carrier networks, with only three link-diverse cross-continental paths.
