22 * DARPA NMS Campus Network Model
23 *
24 * This topology replicates the original NMS Campus Network model
25 * with the exception of chord links (which were never utilized in the
26 * original model)
27 * Link Bandwidths and Delays may not be the same as the original
28 * specifications
29 *
30 * Modified for distributed simulation by Josh Pelkey <jpelkey@gatech.edu>
31 *
32 * The fundamental unit of the NMS model consists of a campus network. The
33 * campus network topology can been seen here:
34 * http://www.nsnam.org/~jpelkey3/nms.png
35 * The number of hosts (default 42) is variable. Finally, an arbitrary
36 * number of these campus networks can be connected together (default 2)
37 * to make very large simulations.
