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. |
