GMPLS update - 66: adding out-segment create/remove API

Added #create / #remove #API for #standard MPLS #out-segment #configuration in GMPLS module. These APIs will be used by the other module procedures to create out-segment entries in the #MPLS-LSR #framework. This will #create the other #dependent #objects of the out-segment. For each standard out-segment entry, one out-segment #statistics entry, one #GMPLS #configuration entry and a #custom #out-segment configuration entry will be created along with it. The create API makes sure that these #hierarchical #entries are in place. The remove API will handle the #cleanup operation of the standard out-segment entry. On removing the standard out-segment entry the related #hierarchical #entries will be #removed from the framework #automatically.

GMPLS update - 60: optimizing standard label stack entries

Optimized #standard #label #stack #entries in GMPLS module. This #removes the #attributes like #label and #pointer to label. The hard-linked #custom #label #stack entries provides the label information of the stack which satisfies the same requirement. The custom out-segment entry is capable of maintaining the label of any media type, hence this will be more useful than the standard entries - which is quite limited. This will reduce the memory requirement associated with the label stack entries.

GMPLS update - 59: optimizing standard out-segment entries

Optimized #standard #out-segment #entries in GMPLS module. This #removes the #attributes like #pointer to #extra #parameters. The hard-linked #custom #out-segment entries provides the extra #parameters on the segment which satisfies the same requirement. The custom out-segment entry holds attributes like #swap-label and #top-label. This will reduce the memory requirement associated with the out-segment entries.

LAG upgrade - 25: removing custom aggregator create API

Removed #custom #aggregator #create / #remove API in LAG module. The custom aggregator entries are #embedded in the #standard #aggregator entries and the standard aggregator create / remove API already handles the required functionality. Hence the redundant external API is being removed.

GMPLS update - 57: optimizing standard out-segment entries

Optimized #standard #out-segment #entries in GMPLS module. This #removes the #attributes like #top-label, #pointer #to top #label and #pointer to #traffic #parameter. The hard-linked #custom #out-segment entries provides #alternate #parameters which satisfies the same requirement and the traffic parameters are derived from the associated tunnel LSP. The custom out-segment entry holds attributes like #swap-label and #top-label. The removed standard attributes support only few media types, but the custom attributes supports #label-types for different media types. This will reduce the memory requirement associated with the out-segment entries.

GMPLS update - 50: corrections in standard MPLS tunnel API

Added #corrections in the #standard #MPLS #external #API in GMPLS module. The #cross-connect based #index #removal #step has been added in the tunnel removal routine. The #standard #extended #MPLS #entries and the #standard #GMPLS #error #entries routines has been #chain #linked in the create / remove routines for the external tunnel API.

GMPLS update - 43: adding external API for GMPLS tunnel create

Added changes for #create / #removal of #GMPLS #tunnel #hierarchical #entries in GMPLS module. This involves the #creation of #dependent #configuration #entries as part of #tunnel / #LSP #create operation and #removal of these #cross #references which were created for maintenance of #dynamic #tunnel #state. On creating a tunnel entry, the #statistics entries are created for both #forward and #reverse traffic directions, the #GMPLS #configuration entry, the #extended #configuration entry and the #custom #configuration entry is created. A tunnel specific #error #entry is created to track the detailed tunnel state and the cause for the state.

LAG upgrade - 9: member port API update

Updated #external #create / #remove #API for #member #ports in LAG module. Removed references to augmented data-structures from these routines. The external #create API creates the member port configuration entry and it's #associated #data-structures like port #statistics and #debugging parameters. The #custom member port parameter entries and #extended configuration entries are also #instantiated along with the create operation. On the #remove call these #dependent #structures are #removed first followed by the member port itself.

GMPLS update - 37: adding in-segment create/remove API

Added #in-segment #create / #remove routines in GMPLS module. These #routines #handles the #hierarchical dependency between the different variants of in-segment configuration #entries. On creating the #standard #in-segment entries they automatically creates the in-segment #statistics entries, in-segment #standard #GMPLS entries and in-segment #extended #custom entries as well.

GMPLS update - 24: removing standard CRLDP resource entries

#Removed #standard #CRLDP #resource parameters from the GMPLS module. These entries holds the #CRLDP specific #resource / #bandwidth #information.

GMPLS update - 16: removing link switching-capability descriptor from GMPLS Call framework

#Remove d #link #switching-capability #descriptor ( #ISCD ) from GMPLS #Call #framework from GMPLS module. The switching-capability descriptor has been removed as the #same #functionality is already available #from the corresponding #TE-Link #switching-capability #descriptor in #TED module. The removed data-structures indicates the switching-capability information of the remote TE-Links conveyed through the Call signaling mechanism. The same information will be populated in the TED module on signaling and used in place, so as to reduce the memory requirement.

IF update - 17: adding interface create/remove handler

Added support for #logical-interface #create / #remove #handler in IF module. On #row-status #change for interfaces in IF module will #call this #handler for #perform ing the #support #procedure s in the respective module. The interface #handler has been #register ed from the #GMPLS module to complete the interface create/remove sequence for MPLS-interface s.

GMPLS interface update - 2: added MPLS interface external API

Added #MPLS-interface #external #API routines in GMPLS module. This enables to #create / #remove #MPLS-interface related #hierarchical #entries through a single API. The standard GMPLS interface entries are also created indirectly through these routine calls. The MPLS interface handle will be using these routine calls to create the MPLS-interface as the side effect of creating the corresponding logical-interface in the IF module. The MPLS interface entries #contain the #attribute s like #current range of #in-coming / #out-going #label s used and the #bandwidth #state.

GMPLS interface update - 1: added MPLS interface create/remove sequence

Added #MPLS-interface #create / #remove #sequence in GMPLS module. This enables to #create #MPLS-interface s #through the #IF #module #interface #management operations. On creating the MPLS logical-interface in the IF module the corresponding interface is created in the GMPLS module through the logical-interface handler routine. On removing the MPLS logical-interface in IF module, corresponding operations are performed in GMPLS module accordingly. The #MPLS-interface #activation and #ADMIN-STATUS operations are performed in the GMPLS module #through the appropriate logical-interface #handler #routine s defined by GMPLS module for the same, and the triggers for these operations are passed from the IF module to GMPLS module through these handlers.

IF update - 14: updating logical interface stacking handler

Updated the #logical-interface #stack #handling routines in IF module. The #stacking #change #handler routines has been #upgraded for the new data-structure changes. The interface stacking change handler will #check with the #upper and #lower #interface #layer s #on #create / #remove operations for each stack slice. e.g. On adding a #TE-Link over an #ethernet port the port capability (L2/L3/MPLS, bandwidth, MTU, duplexity, etc ...) and it's current state (OPER-STATUS) is checked. On creating the TE-Link TE-Link bandwidth is deduced from the lower layer ethernet port speed/bandwidth. On removing an GMPLS / #MPLS-tunnel, the earlier reserved bandwidth is returned back to it's lower layer #MPLS-interface and #TE-Link. These operations are supported through the interface stack change handler.
