Method Detail

supportCopyTtl

protected boolean supportCopyTtl()

Description copied from class: Ofdpa2GroupHandler

Determines whether this pipeline support copy ttl instructions or not.

Overrides:

supportCopyTtl in class Ofdpa2GroupHandler

Returns:

true if copy ttl instructions are supported

supportSetMplsBos

protected boolean supportSetMplsBos()

Description copied from class: Ofdpa2GroupHandler

Determines whether this pipeline support set mpls bos instruction or not.

Overrides:

supportSetMplsBos in class Ofdpa2GroupHandler

Returns:

true if set mpls bos instruction is supported

requireVlanPopBeforeMplsPush

protected boolean requireVlanPopBeforeMplsPush()

Description copied from class: Ofdpa2GroupHandler

Determines whether this pipeline requires popping VLAN before pushing MPLS.

If required, pop vlan before push mpls and add an arbitrary vlan back afterward. MPLS interface group will substitute the arbitrary VLAN with expected VLAN later on.

Overrides:

requireVlanPopBeforeMplsPush in class Ofdpa2GroupHandler

Returns:

true if this pipeline requires popping VLAN before pushing MPLS

requireAllowVlanTransition

protected boolean requireAllowVlanTransition()

Description copied from class: Ofdpa2GroupHandler

Determines whether this pipeline requires AllowVlanTransition in L2 unfiltered group.

Overrides:

requireAllowVlanTransition in class Ofdpa2GroupHandler

Returns:

true if the AllowVlanTransition action is required

createL2L3Chain

protected OfdpaGroupHandlerUtility.GroupInfo createL2L3Chain(org.onosproject.net.flow.TrafficTreatment treatment,
                                                             int nextId,
                                                             org.onosproject.core.ApplicationId appId,
                                                             boolean mpls,
                                                             org.onosproject.net.flow.TrafficSelector meta)

Description copied from class: Ofdpa2GroupHandler

Creates one of two possible group-chains from the treatment passed in. Depending on the MPLS boolean, this method either creates an L3Unicast Group --> L2Interface Group, if mpls is false; or MPLSInterface Group --> L2Interface Group, if mpls is true; The returned 'inner' group description is always the L2 Interface group.

Overrides:

createL2L3Chain in class Ofdpa2GroupHandler

Parameters:

treatment - that needs to be broken up to create the group chain

nextId - of the next objective that needs this group chain

appId - of the application that sent this next objective

mpls - determines if L3Unicast or MPLSInterface group is created

meta - metadata passed in by the application as part of the nextObjective

Returns:

GroupInfo containing the GroupDescription of the L2Interface group(inner) and the GroupDescription of the (outer) L3Unicast/MPLSInterface group. May return null if there is an error in processing the chain

processEcmpHashedNextObjective

protected void processEcmpHashedNextObjective(org.onosproject.net.flowobjective.NextObjective nextObjective)

In OFDPA2 we do not support the MPLS-ECMP, while we do in Open vSwitch implementation.

Overrides:

processEcmpHashedNextObjective in class Ofdpa2GroupHandler

Parameters:

nextObjective - the hashed next objective to support.
