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 - 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.

TED update - 10: adding local and remote IP address based index for TE-Link

#Added #local and #remote #IP #address based #index for #TE-Link in TED module. This will enable to #access the #TE-Link entry based on it's #local-ip-addr and #remote-ip-addr #indexes. This will help to look-up TE-Link entries from the address information. The IP #address on the TE-Link can assume #IPv4, #IPv6 or #un-numbered address #types. The #local #address part of the TE-Link is an #operator #configuration and #remote address part is #dynamically updated as part of the #signaling. The remote address can also be statically updated by the operator in certain scenarios. This helps to efficiently map the TE-Link entries from the address index.
