GMPLS update - 46: optimizing standard extended GMPLS tunnel actual-path entries

Hard-linked #standard #extended GMPLS #tunnel #actual-path through #standard MPLS #tunnel actual-path #entries in GMPLS module. This will indicate the #extended #path-hop #attributes like flags indicating whether #hop-forward-label and #hop-reverse-label are present or not, pointers to these respective labels and #hop-protection status as in whether #local-protection is available in the hop and whether they are using it or not. This will reduce the memory requirement associated with the GMPLS actual-path entries. The hard-linked GMPLS actual-path entries enables accessing them directly from the standard MPLS actual-path entries.

Platform module update - 2: module control API support

Added changes in #platform module for platform #module-control handle API. This will enable the necessary #platform #modules to #perform #module-init and #module-start operation in sequence. The specific platform #module can optionally define the #init operations in the module-control handle and register the control handle on module #registration. The platform will execute the init operation before executing the #start operation, through the control handle. This generalizes and reduces the future platform API changes by defining a #unified #API for all module control operations from the platform.

GMPLS update - 45: upgrading standard MPLS tunnel configuration entries

Upgraded #standard MPLS #tunnel #configuration entries in GMPLS module. The #tunnel-name and #tunnel-description has been set to #limited #size in-line with commonly used #max-limit. The #cross-connect #pointer and #resource-pointer has been removed and the #cross-connect-index and #resource-index defined in #custom MPLS #tunnel #configuration entries will be used instead. This removes the long (and memory hogging) pointer format and uses light weight integer indexes in to the respective configuration entries.

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.

LAG upgrade - 10: optimizing member port configuration entries

Hard-linked #member #port #list #configuration in LAG module. The member port list has been #embedded in the #standard #aggregator configuration #entries. This removes the redundant indexing scheme and optimizes the memory used by the member port list entries. The member port list is a #single #entry corresponding to each #aggregator #port, it contains a #bit-map of member port #interface-indexes.

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.

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.

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.

Added #new #parameters on the #TE-Link in the TED module. The new #attribute #indicates whether the #TE-Link #crosses an #autonomous-system or an #area - i.e. AS / Area #border #link. An #admin-flag parameter has been added to the TE-Link to mark this information. Also the existing #te-adjacency-enable and #te-distribution-scope parameters has been added as #admin-flags to compact the parameters.

#Added new parameters in #custom #TE-Node entries in the TED module. This include the #node-type for indicating the type of the node as #node, #area or the #autonomous-system, the #node-area which identify the area of the local node in a #multi-area #network, the #node-xc-type to indicate that the node has only a #fixed #cross-connect and can not be #reconfigured, and the #node-label-distribution-enable which identify whether or not to #signal the #label related node #capabilities to other nodes. The area and autonomous-system level #summarization #nodes uses the #node-type to indicate the summarization level. The nodes which has a #fixed #connectivity #matrix will limits the way in which the #input port can be connected to the #output #ports. For these kind of nodes the #node-xc-type is set as fixed. Also it is possible to convey the node level #label #constraints to the neighboring nodes to assist in better #path #computation operation.

#Added #standard #TE-Node #ASN / #ICC address based #look-up methods in the TED module. This enables to access the #TE-Nodes in the network based on the #ASN based addressing or the #ITU-T based #ICC #addressing scheme. The #ASN based address scheme involves an #autonomous-system-number ( #ASN ) and the #node-id. This is also referred as the #IP-compatible addressing scheme. In the #ICC addressing scheme the TE-Nodes are addressed by #country-code ( #CC ), #itu-t-carrier-code ( #ICC ) and the #node-id. The new look-up mechanism uses #independent ASN address and ICC #address #mapping methods. This enables to access the TE-Nodes in either of the addressing schemes.
