Francois, Each of the hosts issuing a RESV is waiting for an approval of its request. When aggregation is performed, one might have the case where the aggregate of the reservation could fail due to b/w, etc. In that case, a) shouldn't the aggregator inform the individual hosts with a PathErr message? b) if the condition which caused the PathErr message persists, say due to insufficient b/w for the aggregate, some individual requests could have obtained a PATH if they had been responded individually (i.e. through a PATH message instead of an E2EPATH).
