11 * DARPA NMS Campus Network Model
12 *
13 * This topology replicates the original NMS Campus Network model
14 * with the exception of chord links (which were never utilized in the
15 * original model)
16 * Link Bandwidths and Delays may not be the same as the original
17 * specifications
18 *
19 * Modified for distributed simulation by Josh Pelkey <jpelkey@gatech.edu>
20 *
21 * The fundamental unit of the NMS model consists of a campus network. The
22 * campus network topology can been seen here:
23 * http://www.nsnam.org/~jpelkey3/nms.png
24 * The number of hosts (default 42) is variable. Finally, an arbitrary
25 * number of these campus networks can be connected together (default 2)
26 * to make very large simulations.
