    • Method Detail

      • 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)
        Unmaps 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

      • getTopologycalGraph

        TopologicalGraph getTopologycalGraph()
        Returns:
        the graph
