TED update - 20: adding new TE-Link switching-capability index

Added new #indexing on the #TE-Link #based on the #switching-type and #lsp-encoding-type in the TED module. This will enable to #look-up TE-Link based on the #switching-capability-descriptors available on the link. This will be useful when computing #path for #LSPs of specific #switching-type and #encoding-type. The switching-capability-descriptor of a TE-Link is #derived from it's underlying #component #links. This enables to create #TE-Links #over higher capacity #server-layers e.g. #Ethernet capable TE-Links created over #SDH / #OTN server-layers.

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.

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 - 39: adding out-segment interface index

Added #mpls-interface based #indexing on #out-segment configuration entries in GMPLS module. This will help in doing #search #operations among the out-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 will be #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 - 34: updating standard GMPLS tunnel reverse statistics agent mapper routines

#Updated #standard #GMPLS #tunnel #reverse #statistics 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 GMPLS reverse statistics entries #embedded #in the standard #MPLS #tunnel entries and there by removing the redundant indexing.

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.

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.

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 - 4: adding extended TED parameter framework

Added #extended #custom #TED #parameter s in TED module. The new TED #framework include #node, #link, #link-address and #node-adjacency #databases on the network. The node database include s all TE nodes present in the network. The TE-Links configured on each node is captured in the link database, the addresses by which the links are identified is available in the link-address database. The adjacency information between the nodes and their neighbors are available in node-adjacency database. The #locally #configured #TE-Link information is directly fed to the TED database, also the #TE information #available #from the #external #signaling modules (e.g. #OSPF-TE, #ISIS-TE) is also captured in the TED database.
