PCE now handles flexgrid. However some further developments are required to handle higher rates (such as 400Gbps).
First implementation (400G on a single wavelength use case) consists in providing a path computation for 400GE with a simple configuration of tpdr-400GE (see TRNSPRTPCE-368).
However, the code shall be written, paving the way to intermediate rates handling (200/300G).
First, from "service-rate" at 400G and service format configured to "Ethernet" provided by the SH, PCE path-computation-request needs to be adapted with the service-type that will correspond to higher rate services.
Then the topology shall be pruned to remove all A and Z end points that do not have the ability to handle higher rate services. This pruning will be based on the port capabilities from the portmapping in order to prune invalid nodes from openroadm-topology.
Acceptance criteria : the code does not introduce regressions, and unitary test are provided to check the behavior for 400G services over a single wavelength.
