GMPLS update - 39: adding out-segment interface index

Added #mpls-interface based #indexing on #out-segment configuration entries in GMPLS module. This will help in doing #search #operations among the out-segment entries for #specific #interfaces in a #quick and #efficient manner. On #interface #changes the events are #forwarded to all the segments created on the interface. From segments the events will be #chained to #cross-connects and then further to the parent #tunnel #LSPs. On maintaining the interface index on segments expedite the event chaining process. The mpls-interface is used as an index in to the segment.

GMPLS update - 38: adding in-segment interface index

Added #mpls-interface based #indexing on #in-segment configuration entries in GMPLS module.

TED update - 8: adding TE-Link reservation database

#Added #TE-Link #reservation parameters agent routines in TED module. On #LSP #reservation on the TE-Link an entry is made to keep #track of the #reservation just made. These entries hold the #bandwidth information related to each LSP reservation. On creating a #in-segment over a #mpls-interface, a reservation is done over the respective TE-Link and #link-reservation entry is created. On events like #protection #switching or an #LSP #tear #down the respective link-reservation entries will be appropriately handled. This stands as a #database of all the #reservations done in the system for various services LSPs. This allows to avoid complex cases as #double #reservations, where #backup or #detour #paths are involved. The #bandwidth consumed by each reservation is marked in the #link-reservation entries and when #make-before-break ( #MBB ) use-cases are involved it helps to get current #reservation and make #changes accordingly.

GMPLS update - 22: updating mpls-interface statistics parameters agent mapper routines

#Updated #mpls-interface #statistics parameters agent routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to use standard #mpls-interface #based #indexing. This will access the mpls-interface statistics embedded in the mpls-interface and there by removing the redundant indexing. The mpls-interface statistics entries holds the attributes like the #count of #in-coming and #out-going labels in use, count of #in-coming #label #look-up #failures, count of #out-going #fragmented #packets, etc ... The mpls-interface statistics entries are linked in to the mpls-interface create / remove API, so as to create the statistics entries on creating / removing the respective standard mpls-interface.

GMPLS update - 18: optimizing standard tunnel statistics entries

#Updated #standard #tunnel #statistics agent mapper routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to #use standard #MPLS-tunnel entry based #indexing. This will access the port entries by using the #native #indexing. This removes references to the standard tunnel statistics indexing used earlier. The tunnel statistics #entries add support for #LSP #counter #attributes like #packets and #bytes #forwarded, #packet #errors during #forwarding, etc ...

GMPLS interface update - 4: optimizing MPLS interface statistics entries

#Update d #standard #MPLS-interface #statistics agent mapper routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to use standard MPLS-interface entry based #indexing. This will access the port entries by using the #native #indexing. This removes references to the standard MPLS-interface statistics indexing used earlier. The extended entries add support for #attribute s like #count for #in-coming / #out-going #label s in use on the interface and the #count #of #error s in the #in-coming / #out-going #direction s. The standard MPLS-interface statistics entries has been embedded in the MPLS-interface entries. This will reduce the memory requirement associated with the interface statistics.

GMPLS interface update - 3: added MPLS interface ADMIN-STATUS handler

Added #MPLS-interface #ADMIN-STATUS #handler routine in GMPLS module. This enables to #perform the #support #procedure s for #MPLS-interface s on ADMIN-STATUS change. The handler is register ed with the IF module and #IF #module will #execute this #call-back #on respective #parameter #change in IF module. This helps to perform the necessary procedures in GMPLS module when the ADMIN-STATUS is changed from IF module.

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.
