public class OfOpticalSwitchImplLinc13
extends AbstractOpenFlowSwitch
implements OpenFlowOpticalSwitch

LINC-OE Optical Emulator switch class. The LINC ROADM emulator exposes two types of ports: OCh ports connect to ports in the packet layer, while OMS ports connect to an OMS port on a neighbouring ROADM. LINC sends the tap ports (OCh for our purposes) in the regular port desc stats reply, while it sends *all* ports (both tap and WDM ports, i.e., OCh and OMS) in the experimenter port desc stats reply. As LINC implements custom OF optical extensions (in contrast to the final standard as specified in ONF TS-022 (March 15, 2015), we need to rewrite flow stat requests and flow mods in sendMsg(OFMessage).

public OfOpticalSwitchImplLinc13()

Method Detail

startDriverHandshake

public void startDriverHandshake()

Description copied from interface: OpenFlowSwitchDriver

Starts the driver specific handshake process.

Specified by:

startDriverHandshake in interface OpenFlowSwitchDriver

Specified by:

startDriverHandshake in class AbstractOpenFlowSwitch

isDriverHandshakeComplete

public boolean isDriverHandshakeComplete()

Description copied from interface: OpenFlowSwitchDriver

Checks whether the driver specific handshake is complete.

Specified by:

isDriverHandshakeComplete in interface OpenFlowSwitchDriver

Specified by:

isDriverHandshakeComplete in class AbstractOpenFlowSwitch

Returns:

true is finished, false if not.

processDriverHandshakeMessage

public void processDriverHandshakeMessage(org.projectfloodlight.openflow.protocol.OFMessage m)

Description copied from interface: OpenFlowSwitchDriver

Process a message during the driver specific handshake.

Specified by:

processDriverHandshakeMessage in interface OpenFlowSwitchDriver

Specified by:

processDriverHandshakeMessage in class AbstractOpenFlowSwitch

Parameters:

m - the message to process.

processOFPortStatus

public void processOFPortStatus(org.projectfloodlight.openflow.protocol.OFCircuitPortStatus ps)

getPorts

public List<org.projectfloodlight.openflow.protocol.OFPortDesc> getPorts()

Returns a list of standard (Ethernet) ports.

Specified by:

getPorts in interface OpenFlowOpticalSwitch

Specified by:

getPorts in interface OpenFlowSwitch

Overrides:

getPorts in class AbstractOpenFlowSwitch

Returns:

List of ports

sendMsg

public void sendMsg(org.projectfloodlight.openflow.protocol.OFMessage msg)

Description copied from interface: OpenFlowSwitch

Writes the message to the driver.

Note: Messages may be silently dropped/lost due to IOExceptions or role. If this is a concern, then a caller should use barriers.

Specified by:

sendMsg in interface OpenFlowSwitch

Overrides:

sendMsg in class AbstractOpenFlowSwitch

Parameters:

msg - the message to write

supportNxRole

public Boolean supportNxRole()

Description copied from interface: OpenFlowSwitchDriver

Does this switch support Nicira Role messages.

Specified by:

supportNxRole in interface OpenFlowSwitchDriver

Specified by:

supportNxRole in class AbstractOpenFlowSwitch

Returns:

true if supports, false otherwise.

deviceType

public org.onosproject.net.Device.Type deviceType()

Description copied from interface: OpenFlowSwitch

Returns the switch device type.

Specified by:

deviceType in interface OpenFlowSwitch

Overrides:

deviceType in class AbstractOpenFlowSwitch

Returns:

device type

getPortsOf

public List<? extends org.projectfloodlight.openflow.protocol.OFObject> getPortsOf(PortDescPropertyType type)

Description copied from interface: WithTypedPorts

Return a list of interfaces (ports) of the type associated with this OpenFlow switch.

Specified by:

getPortsOf in interface WithTypedPorts

Parameters:

type - The port description property type of requested ports

Returns:

A potentially empty list of ports.
