                         int numASNodes,
                         int groupingMethod,

Method Detail

toString

public java.lang.String toString()

Description copied from class: Model

All models have a string description which is returned by their toString() method. Usually this is included when exporting the topology generated by that model to a file.

Overrides:

toString in class Model

Following copied from class: Model.Model

Returns:

String

groupNodes

public void groupNodes(Graph g0)

Method: groupNodes(g0) ----------------------- Assign routers in g0 an ASid according to our groupingMethod. A note on assigining IDs: we don't really create a new Node (waste of memory), we simply increment the static int (nodeCount) in the Node class and so are guranteed a unique ID for the AS "node" that the routers will belong to. How Grouping is Done: --------------------- RANDOM_PICK: For each AS node, do the following: First, determine nodesPerAS, the number of routers that will be in this AS (according to the AssignType). Second, randomly pick nodesPerAS routers in the router topology assign them to this AS (and mark them as unavailable for the other ASs). Because of the way routers are assigned to ASs, we could have (should have) disconnected or non-neighbor routers belonging to the same AS. RANDOM_WALK:

AssignBW

public void AssignBW(Edge[] e)

Generate

public Graph Generate()

Description copied from class: Model

All Models that are derived from this base Model class, must override the Generate() method. The Generate() method handles all the model-specific intricacies of: 1) Placing the Nodes 2) Interconnecting the Nodes 3) Assigning Edge weights (bandwidth, delay etc) And other model-specific functionality.

Overrides:

Generate in class Model

Returns:
