LACP upgrade - 11: updating member port distribution and collection handler

Updated #distribution and #collection #handler for #member-ports in #LACP module. The handler #enables the collection and distribution operations #sequentially on each port. After an #aggregator port is selected to be #attached with the member port member port moves to the #synchronized #state with the peer port. i.e. both peer agrees that same aggregator link is used for attaching from both peer systems. Once the synchronization is attained the handler #enables #collection operation on the member port and the #HAL #calls will be done for enabling collecting operation in the #hardware as well. Once this is done, informs the peer about this with an updated LACP PDU. Once both the peers are collecting data from each side of the link for the same aggregator port the #distribution operation will be started on the member port by the handler in the next step. The #HAL call will be done and the updated LACP PDU will be sent to peer to inform them as well. Once both collection and distribution operations are enabled on the member ports the link will be fully participating in the aggregation operation.

LACP upgrade - 10: updating LACP PDU partner info handler

Updated the LACP #PDU #handler in #LACP module. This handler will #process the #PDU while #received on port. The #peer #partner #info of the received port is #updated from the info received in the LACP PDU. The info in the PDU is checked against the actor port specific info to #decide whether the #peer port is in #sync with the received port. The partner info like oper-port, oper-priority, oper-system-id, oper-system-priority, oper-key and oper-stat are populated according to the values received from LDU. The actor specific info like port, port-priority, system-id, system-priority and oper-key are cross checked with the info in PDU to decide whether synchronization has been attained with the peer port.

GMPLS update - 76: adding new parameters in custom actual-path configuration

Adding new #attributes in custom #actual-path configuration GMPLS module. The new attributes #node-id and #link-id adds support for specifying the #path #segment with respect to the #TE-Node and #TE-Link. This helps in describing the tunnel path using the nodes and links along the way. The #address information of the individual links are #automatically #populated based on the specified node-id and link-id configuration. This adds support for specifying the tunnel actual-path without knowing the address information, but using only the links on the way.

GMPLS update - 75: updating custom explicit-path agent mapper routines

Updated #custom #explicit-path agent mapper routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to use standard #explicit-path entry based #indexing. This will access the explicit-path entries by using the #native #indexing. This removes references to the custom explicit-path indexing used earlier. This will reduce the memory requirement associated with the custom explicit-path entries. The custom explicit-path #entries add support for #attributes like #hop-forward-label and #hop-reverse-label. The #label-type attribute adds support for #media #specific labels ( #Ethernet / #SONET / #SDH / #OTN ) through the #label-type and #label-value attributes.

LACP upgrade - 9: updating LACP PDU transmit handler

Updated the #PDU #transmit #handler in the #LACP module. Whenever updated LACP packets has to be sent to the #peer #partner node, the PDUs are #composed from the internal data-structures in this routine. This routine access the member port data-structures for #creating the individual #TLVs in the LACP PDU. The data-structure references has been corrected to the native member port structures. This routine passes the created PDUs to the appropriate #platform #handlers to send them out of the actual port.

LACP upgrade - 6: updating member port aggregator attach handler

Updated #member #port #attach #handler with the aggregator in the #LACP module. This handler make the #hardware calls to #attach the member port with the selected aggregator and mark the member port state as attached. The #remote #peer is informed of this by sending a #new #LACP #PDU and peer is marked as #synchronized. Later, when peer responds with it's PDU the actual #distribution and #collection operations will be #started for member ports. On attaching the member port with the aggregator the LAG distribution and collection operations will be started in hardware. i.e. The traffic sent out on the aggregator port will be distributed to the member ports and traffic received on the member ports will be collected on to the combined aggregator port.

Updated #aggregator #port #status #handler in #LACP module. The data structure has been updated to use the new updated structure. This routine #updates the aggregator status as part of the #administrative or #operational #changes. The #LAG module uses this to #convey the aggregator #status #change to LACP module. When the aggregator port status changes to DOWN current aggregator selection is marked to be cleared. The remote information is marked as expired. This will cause the remote peer information to be gathered fresh again on port UP change. When port state comes as UP, the peer synchronization is marked as lost and expired and a timer is set to start operation on this port again.

GMPLS update - 68: adding asymmetric bandwidth parameter in custom tunnel entries

Added #new #parameters in #custom #MPLS-tunnel #configuration in #GMPLS module. The #reverse-resource-index optional parameter has been added to tunnel configuration. When present it specify the #resource #requirement for the #reverse #direction, other wise resource requirement is assumed to be same for both directions as the normal #resource-index parameter. This enables to specify #asymmetric #bandwidth for #forward and #reverse #tunnel directions. In normal cases forward and reverse directions shares the same resource requirements. But in specific scenarios it is necessary to specify unequal bandwidths for forward and reverse directions. The new parameter caters this requirement and enables to specify different resource configuration for each directions.
