# Number of cluster per leaf is given by cabinetnodes attr.

# - nbsons : degree of inner
# - height : tree heigth
# - cabinetnodes : cluster per leaf
-#
-# Each node is numbered by a DFS in the tree. Each cluster is numbered by the DFS number of the leaf it is attached to and the number of cluster for each leaf.

# Example syntax for hierarchical cluster creation :
# <cluster id="AS_cb1" prefix="cb1-" suffix=".dc1.acloud.com" power="5.2297E9" bw="1.25E8" lat="1.0E-4 bb_bw="1.25E9" bb_lat="1.0E-4" radical="0-99" cabinetnodes="4" height="3" nbsons="2" links_lat="1.0E-4" links_bw="1.25E9"/>
# Other infos :
-# - special tag has to be on one line because I don't want to bother with parsing issues
+# - special tag has to be on one line because I don't want to bother with parsing issues
# - Same bb_lat used for any routers inside (not that complicated to modify too)
# - lame perl ? I'm a script kiddie in perl, it may well be my first perl stuff.
# - Don't try to check or validate the modified file with the DTD, of course, as this is not a part of it.
