public class CpqdOfdpa2VlanPipeline
extends CpqdOfdpa2Pipeline

Driver for software switch emulation of the OFDPA 2.0 pipeline. The software switch is the CPqD OF 1.3 switch. Unfortunately the CPqD switch does not handle vlan tags and mpls labels simultaneously, which requires us to do some workarounds in the driver. This driver is meant for the use of the cpqd switch when MPLS is not a requirement from the ofdpa pipeline. As a result this driver correctly handles both incoming untagged and vlan-tagged packets.

Description copied from class: Ofdpa2Pipeline

Allows routed packets with correct destination MAC to be directed to unicast-IP routing table or MPLS forwarding table.

Overrides:

processEthDstFilter in class CpqdOfdpa2Pipeline

Parameters:

portCriterion - port on device for which this filter is programmed

ethCriterion - dstMac of device for which is filter is programmed

vidCriterion - vlan assigned to port, or NONE for untagged

assignedVlan - assigned vlan-id for untagged packets

applicationId - for application programming this filter

Returns:

list of FlowRule for port-vlan filters

processVersatile

protected Collection<org.onosproject.net.flow.FlowRule> processVersatile(org.onosproject.net.flowobjective.ForwardingObjective fwd)

Description copied from class: Ofdpa2Pipeline

In the OF-DPA 2.0 pipeline, versatile forwarding objectives go to the ACL table.

Overrides:

processVersatile in class CpqdOfdpa2Pipeline

Parameters:

fwd - the forwarding objective of type 'versatile'

Returns:

a collection of flow rules to be sent to the switch. An empty collection may be returned if there is a problem in processing the flow rule
