GMPLS update - 63: updating standard GMPLS tunnel error agent mapper routines

Updated #standard #extended GMPLS #tunnel #error agent routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to use standard #tunnel #based #indexing. This will access the extended tunnel error entries #embedded in the standard #MPLS #tunnel entries and there by removing the redundant indexing. The extended tunnel error entries contain attributes like the #error-type - the kind of error happened on the tunnel (e.g. local configuration error, local dynamic state - shortage of resources, path not found - issues, network protocol failures, etc ...), #error-time, #error-reporter, related #error-tlvs and #error-description, etc ...

GMPLS update - 62: optimizing standard GMPLS computed-path entries

Optimized #standard #extended GMPLS #tunnel #computed-path #entries in GMPLS module. This removes the #extended #path-hop #attributes like flags indicating whether #hop-forward-label and #hop-reverse-label are present or not, the #labels them selves and the #pointers to the external labels. This will reduce the memory requirement associated with the #GMPLS #computed-path-hop entries. The hard-linked #custom GMPLS #computed-path-hop entries provides #alternate custom #parameters which satisfies the same requirement.

LAG upgrade - 26: cleaning up LAG management framework for data-structure changes

Added miscellaneous changes in #management #framework in LAG module. #Cleaned up #aggregator #activation handler and added #initialized aggregator #parameters with their #default values. Corrected standard #extended #member #port #iterator routine to provide reference to the standard member port, so that extended parameters embedded in them can be accessed in the mapper routine. Corrected #member #port #create #API to create #statistics, #debug and #extended port #data-structures as part of the member port creation. Corrected #aggregator #create #API to create the #member port #list as part of aggregator creation.

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 - 48: optimizing standard extended GMPLS tunnel entries

Optimized #standard #extended GMPLS #tunnel entries in GMPLS module. #Reduced some of the #address #variables used on the GMPLS tunnel entries and #removed the pointer to the #extra #parameter. The addresses used for the #RSVP #Notify mechanism has been reduced. These include the #upstream-notify-recepient, #downstream-notify-recepient, #upstream-notify-request-address and #downstream-notify-request-address. The downstream-notify-request-address is the address sent out in the PATH message for requesting the downstream nodes to sent Notify messages when needed, also the upstream-notify-request-address is the address sent out in the RESV message for requesting the upstream nodes to sent Notify messages when needed. The upstream-notify-recepient is the address received in Notify Request in the PATH message from the upstream - which is the default value used in the corresponding downstream-notify-request-address - similarly the downstream-notify-recepient is the address received in Notify Request in the RESV message from the downstream - which is the default value used in the corresponding upstream-notify-request-address. The upstream-notify-recepient is kept in the #PATH #state-block and downstream-notify-request-address in the #outgoing #PATH #state-block. The downstream-notify-recepient is kept in the #RESV #state-block and upstream-notify-request-address in the #forwarded #RESV #state-block. The extra parameters are not used as extended tunnel entries are already in place.

GMPLS update - 47: optimizing standard extended GMPLS tunnel error entries

Hard-linked #standard #extended GMPLS #tunnel #error entries through #standard MPLS #tunnel #entries in GMPLS module.

GMPLS update - 44: optimizing standard extended tunnel configuration entries

Hard-linked #standard #extended GMPLS #tunnel #configuration through #standard MPLS #tunnel #entries in GMPLS module. This will indicate the #extended #tunnel #attributes like #reverse-lsp-pointer to the LSP carrying the traffic in the reverse direction, also when the reverse LSP is part of altogether different tunnel the #reverse-tunnel-index and #reverse-tunnel-instance. This covers the different cases involved in the #associated-bidirectional-tunnel. The #co-routed-bidirectional-tunnels are constructed with a single LSP having cross-connects for both the directions. The associated bidirectional tunnels can be constructed utilizing 2 different LSPs and they can be either part of same tunnel or they can be part of different tunnels.

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. On removing the standard entries the related entries also will be removed.

TED update - 16: adding extended addressing parameters in TE-Link address entries

Added #extended #addressing #parameters with #link-address entries in TED module. The address information has been extended by including the #address #prefix length and the #un-numbered address support. The address #prefix allows to represent #ranges of #address in link-address entries. The #address-prefix holds the #prefix #length of the specified address in the entries. The #un-numbered addresses are represented by #address-unnum parameter. Along with the un-numbered address the #parent #IPv4 #address is also included in the entries. The new parameters allows to represent wide range of address in a compact way and variety of address types are added in the link-address entries.

GMPLS update - 33: adding standard extended TE tunnel parameters

#Added #standard #extended #TE #tunnel parameters in the GMPLS module. This include the #extended #tunnel #parameters for #bi-directional operation as well as parameters to specify the #TE-Node #identifiers as the #head and #tail #nodes for #mpls-tunnels. The #opposite-dir-tunnel pointer is used to refer the tunnel in the #reverse #direction for co-routed bi-directional or associated bi-directional tunnels. The #reverse #LSP could be a #different #LSP of the #same #tunnel in #co-routed #bi-directional use-case or the #same #LSP could function for #both the #directions. For #associated #bi-directional tunnel the #reverse #LSP will be part of an entirely #different #tunnel. The #tunnel-index and the #tunnel-instance parameters specify the respective indexes in the #reverse #tunnel for an associated bi-directional tunnel.
