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.

TED update - 5: adding TE-Link adjustment capability parameters

Added new #adjustment-capability ( #IACD ) information both #on #TE-Link and the individual #component-link level s in TED module. The adjustment-capability enables to capture the #capability and #capacity of each node to #perform #media #conversion #between it's #TE-Links ( #Ethernet-to-SDH, #Ethernet-to-OTN, #OTN-to-WDM, etc ... ). The adjustment-capability indicated as the #higher and #lower #layer #switching-type and #LSP-encoding #of a possible #media #conversion and #bandwidth capacity is indicated per #priority. When a node has different types of - media - TE-Links and it is possible to forward data-stream between these links the internal capacity of the node to perform this conversion is indicated as adjustment-capability.
