Method Detail

programVpnToScfPipeline

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

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.

Parameters:

vpnName - 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

void programScfToVpnPipeline(String vpnName,
                             long scfTag,
                             int servChainTag,
                             long dpnId,
                             int lportTag,
                             boolean isLastServiceChain,
                             int addOrRemove)

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.

Parameters:

vpnName - Vpn instance name, typically the UUID

scfTag - ServiceChainForwarding Tag

servChainTag - 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

void removeVpnPseudoPortFlows(String vpnInstanceName,
                              int vpnPseudoLportTag)

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

Parameters:

vpnInstanceName - Name of the VPN, typically its UUID

vpnPseudoLportTag - Lport tag of the VpnPseudoPort

programElanScfPipeline

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

Programs the needed flows for sending traffic to the SCF pipeline when it is coming from an L2-GW (ELAN) and also for handing over that traffic from SCF to ELAN when the packets does not match any Service Chain.

Parameters:

elanName - Elan instance name, typically the UUID. Needed to retrieve the VNI and the elanTag.

scfTag - ServiceChainForwarding Tag

elanLportTag - LPortTag of the Elan Pseudo Port

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

addOrRemove - States if the flows must be added or removed

programElanScfPipeline

void programElanScfPipeline(String elanName,
                            short tableId,
                            int scfTag,

                            int addOrRemove)

removeElanPseudoPortFlows

void removeElanPseudoPortFlows(String elanName,
                               int elanPseudoLportTag)
