Member Function Documentation

getAllFlows()

List<Flow> org.openkilda.pce.provider.NeoDriver.getAllFlows

(

)

Read flows from Neo4j and covert them in our common representation org.openkilda.messaging.model.Flow

Returns

all flow objects stored in neo4j

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 188 of file NeoDriver.java.

getAvailableNetwork()

AvailableNetwork org.openkilda.pce.provider.NeoDriver.getAvailableNetwork	(	boolean	ignoreBandwidth,
		long	requestedBandwidth
	)

Loads network and ignores all ISLs with not enough available bandwidth if ignoreBandwidth is false.

Parameters

ignoreBandwidth	defines if available bandwidth of links should be taken into account for calculations.
requestedBandwidth	links in path should have enough amount of available bandwidth.

Returns

built network.

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 319 of file NeoDriver.java.

getFlow()

List<Flow> org.openkilda.pce.provider.NeoDriver.getFlow

(

String

flowId

)

Read a single flow from Neo4j and convert to our common representation Flow. In reality, a single flow will typically be bi-directional, so just represent as a list.

Returns

the Flow if it exists, null otherwise.

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 175 of file NeoDriver.java.

getFlowInfo()

List<FlowInfo> org.openkilda.pce.provider.NeoDriver.getFlowInfo

(

)

Interact with the PathComputer to get the FlowInfo for all flows.

Returns

a list containing the "key" flow info for all flows.

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 148 of file NeoDriver.java.

getFlows()

List<Flow> org.openkilda.pce.provider.NeoDriver.getFlows

(

String

flowId

)

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 181 of file NeoDriver.java.

getIsls()

List<IslInfoData> org.openkilda.pce.provider.NeoDriver.getIsls

(

)

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 263 of file NeoDriver.java.

getPath() [1/2]

ImmutablePair<PathInfoData, PathInfoData> org.openkilda.pce.provider.NeoDriver.getPath	(	Flow	flow,
		Strategy	strategy
	)		throws UnroutablePathException, RecoverableException

Gets path between source and destination switch for specified flow.

Parameters

flow	Flow instances

Returns

PathInfoData instances

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 66 of file NeoDriver.java.

getPath() [2/2]

ImmutablePair<PathInfoData, PathInfoData> org.openkilda.pce.provider.NeoDriver.getPath	(	Flow	flow,
		AvailableNetwork	network,
		Strategy	strategy
	)		throws UnroutablePathException, RecoverableException

Gets path between source and destination switches for specified flow in preloaded network topology.

Parameters

flow	Flow instances
network	prepared network where searching will be performed.

Returns

PathInfoData instances

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 76 of file NeoDriver.java.

getSwitches()

List<SwitchInfoData> org.openkilda.pce.provider.NeoDriver.getSwitches

(

)

Implements org.openkilda.pce.provider.PathComputer.

Definition at line 228 of file NeoDriver.java.
