Example 11 with Node

use of org.btrplace.model.Node in project scheduler by btrplace.

the class Network method createDefaultNetwork.

/**
 * Create and attach a default network view to the given model.
 * Basically, the Network consists of a main non-blocking switch connected
 * to all the existing nodes in the model using links with the given
 * bandwidth in Mbit/sec.
 *
 * Note: replace the previous Network view attached to the model (if exists).
 *
 * @param mo    the model to add/replace the Network view
 * @param bw    the links bandwidth
 * @return the new 'default' network view, already attached to the given model
