TED update - 13: optimizing TE-Link link-reservation entries

#Optimized #TE-Link #link-reservation entries in TED module. The #reservation #priority has been added to the link-reservation entries, so that #preemption feature can be optimally implemented for #path #computation procedures. The #link-reservation #index has been made #compact by removing the 4 integer indexes and #replaced them with a #generic 16 byte #wide #index. This helps to keep traffic-engineering module to be less specific to the MPLS framework, as the generic index can be used from other modules as well. Also this makes link-reservation database more easily usable. The #preemption is used for #high #priority #path #setup #requests in the #traffic-engineering module. Preemption is used when #resource #crunch is experienced on a TE-Link for these requests. The #previously placed #low #priority resource #reservations will reused for performing current high priority request. The existing low priority reservations of will be either #teared #down or #moved to a different TE-Link. The bandwidth that got available from handling the low priority reservations will be used for current high priority path setup request.

TED update - 12: optimizing TE-Link switching-capability (ISCD) entries and adjustment-capability (IACD) entries

#Optimized #TE-Link #switching-capability ( #ISCD ) entries and #adjustment-capability ( #IACD ) entries in TED module. The TE-Link switching-capability and adjustment-capability #configuration entries has been made #compact #by making the #bandwidth to #64-bit #fixed size #format. The generic variable size format for these parameters takes quite some memory space. The #switching-capability and #adjustment-capability #configuration for TE-Link #component-links also has been #compacted in the same way. The #switching-capability configuration has #max-lsp-bandwidth for each of the 8 #priority values and fixing them to 64-bit will get ride of the 8 size fields of these parameters reducing the memory size. The #max-lsp-bandwidth is kept in #64-bit #floating-point #format which is always exist as a fixed format. The #adjustment-capability configuration as well has 8 #max-lsp-bandwidth fields for each #priority values, this too has been optimized in the same way.

TED update - 7: adding inter TE-Link cross-connect parameters

Added new node level inter #TE-Link #cross-connect information in TED module. This enables to draw the #possible #cross-connect #constraint present between TE-Links of a node. When this configuration is present in a node, that will be the only possible cross-connects between the specified links. But on the absence of this configuration in a node, links can be inter-connected in any possible combination - i.e. no constraint exist for cross-connect between links. When the #cross-connect is between TE-Links of #different #media #types, a possible #media #conversion has to be performed as per the #adjustment-capability information configured. Hence the TE-Links involved in a cross-connect may be part of same media layer or different media layers. On nodes with #hardware #constraint on link cross-connect this information will be useful in expressing the limitation. This could be used to #compute #path for #tunnel #LSPs in complex networks.

The TE-node entries contain #attributes like #node-id, #autonomous-system-number ( #ASN ), #country-code ( #CC ), #itu-t-carrier-code ( #ICC ) and a local node index for unique reference. This enables to refer the nodes in the network using either using the ASN or the ITU-T based ICC addressing scheme. This also serves as a #database of all #known #nodes in the system. When new nodes gets discovered by the TE signaling modules (e.g. OSPF-TE, ISIS-TE) a dedicated entry will be created for each node, so that it can be referenced in remaining parts of the system (e.g. endpoints of TE-Link). The TE-nodes will be referenced as source, destination or the intermediate nodes of an tunnel LSP path.
