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

verifyHashedNextObjective

public boolean verifyHashedNextObjective(org.onosproject.net.flowobjective.NextObjective nextObjective)

Description copied from class: Ofdpa2GroupHandler

The purpose of this function is to verify if the hashed next objective is supported by the current pipeline.

Overrides:

verifyHashedNextObjective in class Ofdpa2GroupHandler

Parameters:

nextObjective - the hashed objective to verify

Returns:

true if the hashed objective is supported. Otherwise false.

processHashedNextObjective

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

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

Overrides:

processHashedNextObjective in class Ofdpa2GroupHandler

Parameters:

nextObjective - the hashed next objective to support.
