    • addLink

      void addLink​(long srcId, long destId, double bw, double lat)
      Adds a new link in the network topology. The CloudSim entities that represent the source and destination of the link will be mapped to BRITE entities.
      Parameters:
      srcId - ID of the CloudSim entity that represents the link's source node
      destId - ID of the CloudSim entity that represents the link's destination node
      bw - Link's bandwidth
      lat - link's latency
      To do something:
      It should receive entities instead of IDs

    • mapNode

      void mapNode​(long cloudSimEntityID, int briteID)
      Maps a CloudSim entity to a BRITE node in the network topology.
      Parameters:
      cloudSimEntityID - ID of the entity being mapped
      briteID - ID of the BRITE node that corresponds to the CloudSim
      To do something:
      It should receive an CloudSim entity instead of an ID

    • unmapNode

      void unmapNode​(long cloudSimEntityID)
      Un-maps a previously mapped CloudSim entity to a BRITE node in the network topology.
      Parameters:
      cloudSimEntityID - ID of the entity being unmapped
      To do something:
      It should receive an CloudSim entity instead of an ID

    • getDelay

      double getDelay​(long srcID, long destID)
      Calculates the delay between two nodes.
      Parameters:
      srcID - ID of the CloudSim entity that represents the link's source node
      destID - ID of the CloudSim entity that represents the link's destination node
      Returns:
      communication delay between the two nodes
      To do something:
      It should receive entities instead of IDs

    • isNetworkEnabled

      boolean isNetworkEnabled()
      Checks if the network simulation is working. If there were some problem during creation of network (e.g., during parsing of BRITE file) that does not allow a proper simulation of the network, this method returns false.
      Returns:
      $true if network simulation is working, $false otherwise

    • getTopologicalGraph

      TopologicalGraph getTopologicalGraph()
      Returns:
      the graph
