A method for controlling the establishment of a connection with a transport network, said message consisting of extracting from a first signaling message a piece of switching status information for a transport switch of said node, configuring said transport switch within said switching status (), estimating () a piece of time information regarding the configuration of said transport switch and generating a second signaling message intended for a network element of said transport network, said second signaling message comprising a piece of time information for determining a configuration end date of said transport switch. Said second signaling message may be transmitted without waiting for the end of communication of said transport switch. A controller is also described.

Method for controlling the establishment of a connection within a transport network

A method for communicating risk information within a network including a plurality of domains connected to one another at the border nodes of said domains, characterized by steps consisting of:

Communicating risk information within a multi-domain network

In order to determine a spectral route for a given connection in an optical telecommunications network (T) between a starting node (ON) and a destination node (ON) of the network, the method consists in: using a conventional routing method to determine one or more candidate spatial routes (Route i, Route) connecting the starting node (ON) to the destination node (ON), each candidate spatial route comprising a sequence of route segments, each segment connecting two nodes of the network directly and being adapted to support a plurality of spectral routes.

Method of determining a spectral route for a given connection in an optical telecommunications network

The switching system comprises a routing device having selection modules each having one input and a plurality of outputs adapted to switch spectral channels received selectively to respective outputs as a function of a command. The routing device comprises a first stage comprising a plurality of modules whose inputs constitute the input ports of the device, a second stage comprising at least one first selection module whose outputs constitute the output ports of the device, and an intermediate stage for coupling the input of the first selection module of the second stage both to a first output of a first selection module of the first stage and to a first output of a second selection module of the first stage. The switching system applies to interconnection panels in switching nodes for optical networks.
