18  * DARPA NMS Campus Network Model
19  *
20  * This topology replicates the original NMS Campus Network model
21  * with the exception of chord links (which were never utilized in the
22  * original model)
23  * Link Bandwidths and Delays may not be the same as the original
24  * specifications
25  *
26  * Modified for distributed simulation by Josh Pelkey <jpelkey@gatech.edu>
27  *
28  * The fundamental unit of the NMS model consists of a campus network. The
29  * campus network topology can been seen here:
30  * http://www.nsnam.org/~jpelkey3/nms.png
31  * The number of hosts (default 42) is variable. Finally, an arbitrary
32  * number of these campus networks can be connected together (default 2)
33  * to make very large simulations.
