Constructor Detail

LinkUpdateContext

public LinkUpdateContext(org.opendaylight.controller.md.sal.binding.api.ReadWriteTransaction tx,
                         InventoryReader reader)

Construct a new instance.

Parameters:

tx - A ReadWriteTransaction instance.

reader - A InventoryReader instance.

Method Detail

addVtnLink

public VtnLink addVtnLink(org.opendaylight.yang.gen.v1.urn.tbd.params.xml.ns.yang.network.topology.rev131021.LinkId lid,
                          SalPort src,
                          SalPort dst)
                   throws VTNException

Add the given inter-switch link information detected by topology-manager into the VTN inventory data.

Parameters:

lid - The identifier of the created link.

src - A SalPort instance corresponding to the source of the created link.

dst - A SalPort instance corresponding to the destination of the created link.

Returns:

A VtnLink instance if the given link was added. null if not added.

Throws:

VTNException - An error occurred.

resolveIgnoredLinks

public void resolveIgnoredLinks()
                         throws VTNException

Try to resolve ignored inter-switch links.

Throws:

VTNException - An error occurred.

updateStaticTopology

public void updateStaticTopology(SalPort sport,
                                 VtnPort vport)
                          throws VTNException

Update static network topology configured to the given switch port.

Note that this method never resolves ignored links even if one or more static links are removed.

Parameters:

sport - A SalPort instance which specifies the target port.

vport - A VtnPort associated with sport.

Throws:

VTNException - An error occurred.

restoreVtnLinks

public VtnPort restoreVtnLinks(SalPort sport,
                               VtnPort vport)
                        throws VTNException

Restore inter-switch links on the given switch port from the MD-SAL network topology.

The caller must guarantee that all the following conditions are met.

• The given port is in UP state.
• No inter-switch link is configured in the given VtnPort.

Parameters:

sport - A SalPort instance which indicates the target switch port.

vport - A VtnPort associated with sport.

Returns:

A VtnPort instance which contains the latest information about the port specified by sport.

Throws:

VTNException - An error occurred.

recordLogs

public void recordLogs(org.slf4j.Logger log)

Record logs for updated links.

Parameters:

log - A Logger instance.
