-## PathComp Impact
-After retrieving the topology, if the service has a duration constraint configured, the PathComp component should interrogate the Forecaster and request a topology forecast according to the requested duration of the service. The computed link capacity forecast should be used as link capacity in path computations.
-
-```
-  link_capacities : Dict[str, float] = dict() # link_uuid => available_capacity_gbps
-  service_duration = get_service_duration(request.service)
-  if service_duration is None:
-    topology = context_client.GetTopologyDetails(topology_id)
-    for link in topology.links:
-      link_capacities[link.link_id.uuid] = link.available_capacity_gbps
-  else:
-    forecast_request = ForecastTopology(
-      topology_id = TopologyId(service.context_id, admin),
-      forecast_window_seconds = service.duration
-    )
-    forecast_reply = forecaster_client.ComputeTopologyForecast(forecast_request)
-    for link_capacity in forecast_reply.link_capacities:
-      total_capacity_gbps = link_capacity.total_capacity_gbps
-      forecast_used_capacity_gbps = link_capacity.forecast_used_capacity_gbps
-      forecast_available_capacity_gbps = total_capacity_gbps - forecast_used_capacity_gbps
-      link_capacities[link_capacity.link_id.uuid] = forecast_available_capacity_gbps
-
-  # Continue path computation passing link_capacities to the path comp algorithms.
