public class CpqdOfdpa2Pipeline
extends Ofdpa2Pipeline

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 required. As a result this driver works only on incoming untagged packets.

Method Detail

init

public void init(org.onosproject.net.DeviceId deviceId,
                 org.onosproject.net.behaviour.PipelinerContext context)

Specified by:

init in interface org.onosproject.net.behaviour.Pipeliner

Overrides:

init in class Ofdpa2Pipeline

processFilter

protected void processFilter(org.onosproject.net.flowobjective.FilteringObjective filt,
                             boolean install,
                             org.onosproject.core.ApplicationId applicationId)

Description copied from class: Ofdpa2Pipeline

As per OFDPA 2.0 TTP, filtering of VLAN ids, MAC addresses (for routing) and IP addresses configured on switch ports happen in different tables. Note that IP filtering rules need to be added to the ACL table, as there is no mechanism to send to controller via IP table.

Overrides:

processFilter in class Ofdpa2Pipeline

Parameters:

filt - the filtering objective

install - indicates whether to add or remove the objective

applicationId - the application that sent this objective

processVlanIdFilter

protected List<org.onosproject.net.flow.FlowRule> processVlanIdFilter(org.onosproject.net.flow.criteria.PortCriterion portCriterion,
                                                                      org.onosproject.net.flow.criteria.VlanIdCriterion vidCriterion,
                                                                      org.onlab.packet.VlanId assignedVlan,
                                                                      org.onosproject.core.ApplicationId applicationId)

Description copied from class: Ofdpa2Pipeline

Allows untagged packets into pipeline by assigning a vlan id. Vlan assignment is done by the application. Allows tagged packets into pipeline as per configured port-vlan info.

Overrides:

processVlanIdFilter in class Ofdpa2Pipeline

Parameters:

portCriterion - port on device for which this filter is programmed

vidCriterion - vlan assigned to port, or NONE for untagged

assignedVlan - assigned vlan-id for untagged packets
