-This is an example topology for the distributed cloud emulator (dcemulator).
-(c) 2015 by Manuel Peuster <manuel.peuster@upb.de>
-
-
-This is an example that shows how a user of the emulation tool can
-define network topologies with multiple emulated cloud data centers.
-
-The definition is done with a Python API which looks very similar to the
-Mininet API (in fact it is a wrapper for it).
-
-We only specify the topology *between* data centers not within a single
-data center (data center internal setups or placements are not of interest,
-we want to experiment with VNF chains deployed across multiple PoPs).
-
-The original Mininet API has to be completely hidden and not be used by this
-script.
