TED update 22: updated TE-Link cross-connect configuration

Updated #TE-Link #cross-connect configuration in #TED module. The new update indicates whether the #direction of cross-connect in #uni-directional cases. i.e It indicates the direction as #ingress / #egress corresponding to the #order of from-to #port #tuple specified in the cross-connect. This enables to specify either the #incoming / #outgoing port as the #first in the from-to tuple. This will be #relevant when conveying this information through the #signaling modules, as the operator may specifically want to specify the order of ports in from-to tuple. In addition to it is also possible to indicate the cross-connect as uni-directional/bi-directional. The above property is specifically used when the cross-connect is in #simplex mode.

Updated #MPLS-Tunnel #explicit-path configuration entries in GMPLS module to #reduce the necessary #parameters. The parameters #hop-as-number, #hop-lsp-id and #hop-path-computation-type have been removed. Instead of these parameters the #hop-address-type and #hop-address parameters are used. On specifying the #AS-Number or the #LSP-Id the hop-address-type is marked specifically for it and the hop-address will contain the value. The hop-path-computation-type is not used as it was marked obsolete by GMPLS framework and #tunnel-path-computation-type is used. The #path-computation-type is only specified in the tunnel level.

GMPLS update - 80: optimizing tunnel session attribute

Updated #session-attribute parameter for #MPLS-Tunnel in GMPLS module. The parameter size has been fixed to specific bytes and hence the #length variable for the parameter has been removed. The agent handler for this parameter has been updated to remove the variable length from use. This reduces the memory required to hold the session-attribute parameter. The session-attribute will keep track of the parameters like #fast-reroute-enabled, #merging-permitted, #persistence-enabled, #route-pinned, #record-route, etc... The fast-reroute-enabled parameter enables the upstream node to safely reroute the tunnel on a downstream link or node failure using a local-repair mechanism. The merging-permitted parameter enables the transit routers to merge the tunnels with the same destination, this is used on a resource crunch or better scaling of the network. The persistence-enabled parameter causes to automatically retry to reestablish the tunnel on a failure. The route-pinned parameter causes the dynamically computed path to be used permanently as an explicit-path. The record-route parameter causes the transit routes to be recorded and send back to the tunnel head-node.

The reroute_upstream_enable controls the capability to reroute the tunnel from upstream node and procedures to request reroute. The crankback_model indicates the specific model being followed by the stack e.g. end-to-end-rerouting, boundary-rerouting or segment-rerouting and crankback_enable controls whether crankback operations are permitted or not. The softpreemption_enable parameter enables the soft-preemption procedures - when needed. The oam_enable enables/disables OAM procedures on the tunnel.

LACP upgrade - 12: updating member port selection handler

Updated #member-port #selection #handler in #LACP module. This handler checks and #verifies whether the #peer #partner and the #peer #port #attributes are not changing. The peer port info is recorded while LACP PDU is received. While there is an #administrative #configuration change from the peer side or a #physical #connectivity #changes happens from the remote side, it has to be decided whether the #member-port can still be part of #aggregation or not. The handler reads out the attributes passed in the LACP PDU and compare them against the peer port info recorded earlier. When the attributes differ in the PDU the member-port is marked as not part of the aggregation and #member-port #selection #procedures are executed.

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 - 5: updating aggregator port state update handler

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.
