Method Detail

programVpnToScfPipeline

public void programVpnToScfPipeline(String vpnId,
                                    short tableId,
                                    long scfTag,
                                    int lportTag,
                                    int addOrRemove)

Description copied from interface: ICloudServiceChain

Creates/removes the flows that send the packets from a VPN to the SCF domain. These flows are programmed in all DPNs where the VPN has footprint.

Specified by:

programVpnToScfPipeline in interface ICloudServiceChain

Parameters:

vpnId - Vpn instance name, typically the UUID

tableId - Id of the SCF pipeline to where LPortDispatcher must send the packet. Typically it should by Uplink or Downlink Dynamic Subs Filter

scfTag - ServiceChainForwarding Tag

lportTag - LportTag of the VPN Pseudo Logical Port

addOrRemove - states if pipeline must be created or removed

programScfToVpnPipeline

public void programScfToVpnPipeline(String vpnId,
                                    long scfTag,
                                    int scsTag,
                                    long dpnId,
                                    int lportTag,
                                    boolean isLastServiceChain,
                                    int addOrRemove)

Description copied from interface: ICloudServiceChain

Creates/removes the flows that handover packets from SCF pipeline to a specific VPN. This happens when there is a ScHop with an egressPort that is the VpnPseudoLPort.

Specified by:

programScfToVpnPipeline in interface ICloudServiceChain

Parameters:

vpnId - Vpn instance name, typically the UUID

scfTag - ServiceChainForwarding Tag

scsTag - Service Chain Tag

dpnId - DPN where the ingress Port of the ScHop is located

lportTag - Lport tag of the VpnPseudoPort

isLastServiceChain - Only considered in removal operations. States if there are no more ServiceChains using the VPNPseudoPort as egress port.

addOrRemove - States if the flows must be added or removed

removeVpnPseudoPortFlows

public void removeVpnPseudoPortFlows(String vpnInstanceName,
                                     int vpnPseudoLportTag)

Description copied from interface: ICloudServiceChain

Removes all Flow entries (LFIB + LPortDispatcher) that are related to a given VpnPseudoLport.

Specified by:

removeVpnPseudoPortFlows in interface ICloudServiceChain

Parameters:

vpnInstanceName - Name of the VPN, typically its UUID

vpnPseudoLportTag - Lport tag of the VpnPseudoPort

programElanScfPipeline

public void programElanScfPipeline(String elanName,
                                   short tableId,
                                   long scfTag,
                                   int elanLportTag,
                                   boolean isLastServiceChain,
                                   int addOrRemove)
