A method for planning a plurality of optical connections as a function of a plurality of traffic demand (dl-d3) comprising:
in a routing step:
allocating a loopless network path to each traffic demand,
allocating each traffic demand (dl-d3) to a candidate optical connection (c1-c3) or chain of candidate optical connections selected so as to carry the capacity of the traffic demand along the loopless network path allocated to the traffic demand,
and in an optimization step:
defining a reduced set of candidate optical connections (c2-c3) by withdrawing the candidate optical connection to be withdrawn (cl),
for each traffic demand (dl) allocated to the candidate optical connection to be withdrawn,
determining a candidate optical connection or a chain of candidate optical connections to be re-used among the reduced set of candidate optical connections (c2-c3), and
re-allocating the traffic demand (dl) to the candidate optical connection or chain of candidate optical connections to be re-used. |
