33.3 Creating large Hierarchical topologies

The previous section describes methods to create hierarchical topologies by hand. However, there is a script available in ns that converts Georgia-tech's SGB-graphs into ns compatible hierarchical topologies. Please refer to http://www-mash.CS.Berkeley.EDU/ns/ns-topogen.html for downloading as well as instructions on using the hierarchical converter package.

See hier-rtg-10.tcl and hier-rtg-100.tcl in ~ns/tcl/ex for example scripts of hier routing on small and large topologies respectively.
