BRITE's Topology Generation Parameters
  (More information at www.cs.bu.edu/brite/docs.html)
Flat Topology (AS Only or Router Only) Parameters:
Parameter Meaning Possible Values
HS Length of one side of the plane (number of unit squares) Integer > 0
LS Length of inner plane Integer > 0
N Number of nodes in the graph N <= HS x HS
Model Use one of the models built into BRITE Waxman, Barabasi
alpha, beta Distribution parameters for Waxman Model 0< alpha:float < 1 ;  beta:float>0
m Number of links added per new node Integer > 0
Node Placement Dictates how nodes are placed on the plane Random, Heavy Tailed
Growth Type Dictates how Edges are created between nodes Incremental, All
Bandwidth Distr Dictates how bandwidth is assigned to edges Constant, Uniform, Exponential, Heavy-Tailed
MaxBW, MinBW The maximum, minimum bandwidth assigned to an edge Float > 0
Top Down Hierarchical Parameters:
Parameter Meaning Possible Values
Edge Connection Edge Connection Method used to connect disconnected router topologies in Top Down Hierarchical Topology Model Random Node, Smallest Degree Node, Smallest Degree Non-Leaf Node,  k-Degree Node (These were all borrowed from GT-ITM)
Intra BW Dist Dictates how bandwidth is assigned within each AS.  (Overrides the bandwidth distribution selected for router level) Constant, Uniform, Exponential, Heavy-Tailed
Intra BWMax/Min The maximum, minimum bandwidth assigned to an edge connecting two routers in the same AS Float > 0
Inter BW Dist Dictates how bandwidth is assigned to edges connecting two different ASes. Constant, Uniform, Exponential, Heavy-Tailed
Inter BWMax/Min The maximum, minimum bandwidth assigned to an edge connecting border routers. Float > 0
Bottom Up Hierarchical Parameters:
Parameter Meaning Possible Values
AssignType Dictates how many routers are given to each AS.  If Constant, each AS gets N/NumAS routers.   Constant, Uniform, Exponential, Heavy-Tailed
NumAS Number of AS nodes to group router nodes into Integer > 0
Grouping Method How router nodes are grouped into AS RandomPick: Randomly selects routers according to AssignType for each AS.  As a result, each AS may have disconnected router topologies.
RandomWalk: Randomly traverses the graph until the number of router nodes for each AS is reached.  This gurantees that each AS has a connected corresponding router topology.
Inter BW Dist: Dictates how bandwidth is assigned to edges connecting two different ASes. Constant, Uniform, Exponential, Heavy-Tailed
Max BW, Min BW The maximum, minimum bandwidth assigned to an edge connecting border routers. Float > 0
Miscellaneous Parameters:
Export Format Options The format that a generated topology should be saved as. BRITE: Save current topology in the BRITE file format.
OTTER: Otter is CAIDA's network topology visualization tool and can be found at www.caida.org/tools. Selecting this option creates a file format that is understood by Otter.
