TED update 22: updated TE-Link cross-connect configuration

Updated #TE-Link #cross-connect configuration in #TED module. The new update indicates whether the #direction of cross-connect in #uni-directional cases. i.e It indicates the direction as #ingress / #egress corresponding to the #order of from-to #port #tuple specified in the cross-connect. This enables to specify either the #incoming / #outgoing port as the #first in the from-to tuple. This will be #relevant when conveying this information through the #signaling modules, as the operator may specifically want to specify the order of ports in from-to tuple. In addition to it is also possible to indicate the cross-connect as uni-directional/bi-directional. The above property is specifically used when the cross-connect is in #simplex mode.

GMPLS update - 71: updating custom cross-connect agent mapper routines

Updated #custom #cross-connect agent mapper routines in GMPLS module. The agent #iterator routines and #mapper #routine has been updated to use standard #cross-connect entry based #indexing. This will access the cross-connect entries by using the #native #indexing. This removes references to the custom cross-connect indexing used earlier. This will reduce the memory requirement associated with the custom cross-connect entries. The custom cross-connect #entries add support for #label-stack #attributes like #cross-connect-type which indicate the cross-connect as part of LSP/pseudo-wire, also it indicates whether cross-connect is used in #HLSP or #SLSP modes.

GMPLS update - 61: adding cross-connect out-segment based indexing

Added #out-segment based #index for #cross-connects in GMPLS module. This will enable to #access the #cross-connect entry based on it's #out-segment, #in-segment #index pair. This will help to look-up cross-connect entries from the out-segment information. This is used to #pass the #trigger to the #cross-connect on #out-segment level #changes. This helps to efficiently map the cross-connect entries from the out-segment index.

GMPLS update - 55: adding standard tunnel activation handler

Added the #tunnel #activation #handler in GMPLS module. This will change the #tunnel #state as #active / #not-in-service effectively #enabling / #disabling the tunnel operation. On activating the tunnel depending on the tunnel type further actions will change. For a #static tunnel, the #bandwidth #reservation will be performed on the lower links and the #external #paths will be found in that process. The #cross-connects and the #segments will be created and they will be further made active, effectively cascading the activation operation. For #dynamically #signaled #tunnels the signaling modules will take over the further operations.

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 - 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 - 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.

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.
