Detailed Description

Semantically, this class represents an "available network". That means everything in it is active, and the available bandwidth of the isl links matches the criteria specified.

It supports unidirectional links - ie either Inbound or Outbound can be null.

Constructor & Destructor Documentation

◆ AvailableNetwork() [1/2]

org.openkilda.pce.model.AvailableNetwork.AvailableNetwork	(	Driver	driver,
		boolean	ignoreBandwidth,
		long	requestedBandwidth
	)

Main constructor that reads topology from the database.

Definition at line 58 of file AvailableNetwork.java.

◆ AvailableNetwork() [2/2]

org.openkilda.pce.model.AvailableNetwork.AvailableNetwork ( Driver driver )

Creates empty representation of network topology.

Member Function Documentation

◆ addIslsOccupiedByFlow()

void org.openkilda.pce.model.AvailableNetwork.addIslsOccupiedByFlow	(	String	flowId,
		boolean	ignoreBandwidth,
		long	flowBandwidth
	)

Since flow might be already existed and occupied some isls we should take it into account when filtering out ISLs that don't have enough available bandwidth.

Parameters

flowId	current flow id.
ignoreBandwidth	defines whether bandwidth of links should be ignored.
flowBandwidth	required bandwidth amount that should be available on ISLs.

Definition at line 198 of file AvailableNetwork.java.

◆ addLink()

AvailableNetwork org.openkilda.pce.model.AvailableNetwork.addLink	(	SwitchId	srcDpid,
		SwitchId	dstDpid,
		int	srcPort,
		int	dstPort,
		int	cost,
		int	latency
	)

Creates switches (if they are not created yet) and ISL between them.

Definition at line 89 of file AvailableNetwork.java.

◆ getCounts()

Map<String, Integer> org.openkilda.pce.model.AvailableNetwork.getCounts ( )

This call can be used to determine the effect of things like reduceByCost and removeSelfLoops.

Returns: The count of switches, neighbors, ISLs

Definition at line 112 of file AvailableNetwork.java.

◆ getSimpleSwitch()

SimpleSwitch org.openkilda.pce.model.AvailableNetwork.getSimpleSwitch ( SwitchId dpid )

Definition at line 104 of file AvailableNetwork.java.

◆ getSwitches()

Map<SwitchId, SimpleSwitch> org.openkilda.pce.model.AvailableNetwork.getSwitches ( )

Definition at line 100 of file AvailableNetwork.java.

◆ reduceByCost()

void org.openkilda.pce.model.AvailableNetwork.reduceByCost ( )

Call this function to reduce the network to single (directed) links between src and dst switches. The algorithm runs on the Outgoing and the Incoming links, which could have different values. Consequently, one of these could be null by the end.

Definition at line 150 of file AvailableNetwork.java.

◆ removeSelfLoops()

AvailableNetwork org.openkilda.pce.model.AvailableNetwork.removeSelfLoops ( )

Eliminate any self loops (ie src and dst switch is the same.

Returns: this

Definition at line 182 of file AvailableNetwork.java.

◆ sanityCheck()

void org.openkilda.pce.model.AvailableNetwork.sanityCheck ( )

This function can be / should be called after initialization so that all of the checks can be made to ensure the data is okay.

Definition at line 135 of file AvailableNetwork.java.

◆ toString()

String org.openkilda.pce.model.AvailableNetwork.toString ( )

Definition at line 267 of file AvailableNetwork.java.
