| 1. A control device for a node in an Ethernet communications network having a GMPLS control plan and through which node a
connection for setting up is to pass, the device being characterized in that it comprises:
control means arranged, in the event of said node receiving a connection setup message containing at least one first value
representative of a sum since a beginning of said connection for setting up of local values of an additive parameter as introduced
in each of the preceding nodes in said connection, to;
determine a second value that is a function of said first value and of the local value as introduced by said node,
compare said second value with a selected threshold so as to determine whether said connection can accept a maximum value
for said additive parameter at said node,
and replace said first value in said received message with said second value as determined, at least when said connection
can accept said maximum value.
