GMPLS update - 61: adding cross-connect out-segment based indexing

Added #out-segment based #index for #cross-connects in GMPLS module. This will enable to #access the #cross-connect entry based on it's #out-segment, #in-segment #index pair. This will help to look-up cross-connect entries from the out-segment information. This is used to #pass the #trigger to the #cross-connect on #out-segment level #changes. This helps to efficiently map the cross-connect entries from the out-segment index.

GMPLS update - 58: optimizing standard in-segment entries

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

GMPLS update - 52: optimizing standard in-segment entries

Optimized #standard #in-segment #entries in GMPLS module. This #removes the #attributes like #in-coming #label, #pointer to in-coming #label and #pointer to #traffic #parameter. The hard-linked #custom #in-segment entries provides #alternate #parameters which satisfies the same requirement and the traffic parameters are derived from the associated tunnel LSP. This will reduce the memory requirement associated with the in-segment entries.

GMPLS update - 42: updating custom GMPLS in-segment configuration entries

Updated #indexing information for #custom #in-segment #configuration in GMPLS module. Updated #agent #traversal routines and #mapper routine respectively for the indexing update. These changes access the custom in-segment entries directly from the #standard #in-segment entries. This will access the in-segment entries by using the #native #indexing. This removes references to the custom in-segment indexing used earlier. The custom MPLS in-segment #entries add support for #media #specific labels ( #Ethernet / #SONET / #SDH / #OTN ) by maintaining the GMPLS #label-type and #label-value #attributes.

GMPLS update - 40: adding in-segment activation handler

Added #in-segment #activation #handler in GMPLS module. On activating the in-segment it #enables the #LSP #segment operations on it. i.e. It #starts #receiving the #LSP #labelled #data on the interface. When cross-connect is also activated the received data will switched to the respective out-segments - with the respective out-going labels. And further passed to the out-going interfaces, thus completing the #label-switched #data-path.

GMPLS update - 38: adding in-segment interface index

Added #mpls-interface based #indexing on #in-segment configuration entries in GMPLS module. This will help in doing #search #operations among the in-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 #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 - 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. On removing the standard entries the related entries also will be removed.

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.
