    • Method Detail

      • getUplinkBandwidth

        double getUplinkBandwidth()
        Returns:
        Bandwitdh of uplink (in Megabits/s).

      • setUplinkBandwidth

        void setUplinkBandwidth​(double uplinkBandwidth)

      • getDownlinkBandwidth

        double getDownlinkBandwidth()
        Returns:
        Bandwitdh of downlink (in Megabits/s).

      • setDownlinkBandwidth

        void setDownlinkBandwidth​(double downlinkBandwidth)

      • getPorts

        int getPorts()
        Gets the number of ports the switch has.
        Returns:

      • setPorts

        void setPorts​(int ports)

      • getSwitchingDelay

        double getSwitchingDelay()
        Returns:
        the latency time the switch spends to process a received packet. This time is considered constant no matter how many packets the switch have to process (in seconds).

      • setSwitchingDelay

        void setSwitchingDelay​(double switchingDelay)

      • getUplinkSwitches

        List<Switch> getUplinkSwitches()

      • getHostList

        List<NetworkHost> getHostList()
        Gets a read-only list of Hosts connected to the switch.
        Returns:

      • connectHost

        void connectHost​(NetworkHost host)
        Connects a NetworkHost to the switch, by adding it to the getHostList().
        Parameters:
        host - the host to be connected to the switch

      • disconnectHost

        boolean disconnectHost​(NetworkHost host)
        Disconnects a NetworkHost from the switch, by removing it from the getHostList().
        Parameters:
        host - the host to be disconnected from the switch
        Returns:
        true if the Host was connected to the switch, false otherwise

      • getPacketToHostMap

        Map<NetworkHost,​List<HostPacket>> getPacketToHostMap()
        Returns:
        a read-only map of hosts and the list of packets to be sent to each one.
