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.

TCP-UDP update 1: optimizing agent framework

Updated the #agent #framework in TCP-UDP module. The #generic #TCP-UDP #framework has been #optimized to use shorter #variable #names and removed the #length variable for many #multi-size #parameters. This makes uses of short & easier variable names. The memory size of many multi-size variables have been made static and length support has been removed reducing the memory requirement.

CFM update - 3: optimizing agent framework for VLAN & Component support

Updated the #agent #framework in CFM module for #VLAN & #Component support. The VLAN & Component aware #CFM #framework has been #optimized to use proper #variable #names and removed the #length variable for many #multi-size #parameters. All the VLAN aware part of CFM framework has been upgraded this way. This makes uses of straight forward variable names.

GMPLS update - 83: updating custom actual-path agent mapper routines

Updated #custom #actual-path agent mapper routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to use standard #actual-path entry based #indexing. This will access the actual-path entries by using the #native #indexing. This removes references to the custom actual-path indexing used earlier. This will reduce the memory requirement associated with the custom actual-path entries. The custom actual-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.

GMPLS update - 82: adding new parameters in custom computed-path configuration

Adding new #attributes in custom #computed-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 computed-path without knowing the address information, but using only the links on the way.

GMPLS update - 81: reducing explicit-path configuration parameters

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.

GMPLS update - 77: adding new set of custom tunnel configuration parameters

Added new set of #custom #configuration #parameters for #tunnels in #GMPLS module. The new parameters are #reroute_upstream_enable, #upstream_resource_index, #crankback_model, #crankback_enable, #crankback_list_index, #softpreemption_enable, #oam_enable and #oam_status. 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.
