Method to re-provision bandwidth in P-OTN network based on current traffic demand

A node, comprising:

• an input interface for receiving traffic from a first link;
• an output interface for transmitting traffic to a second link;
• a switch for communicating the traffic from the input interface to the output interface;
• and
• a control module controlling the input interface, the output interface, and the switch, the control module:
• measuring a peak of a first bandwidth of data traffic of a transport path over a time period, the transport path passing through a plurality of nodes and conforming to a protocol using a number of time slots to allocate a second bandwidth to the transport path;
• and
• passing a signal, from the node to at least one of the plurality of nodes of the transport path, the signal including at least one instruction that when executed by circuitry of the at least one of the plurality of nodes causes a change to the number of time slots allocated to the transport path based upon the measured peak of the first bandwidth of data traffic, wherein the change to the number of time slots is an increase in the number of time slots by an added number of time slots, the signal being a GMPLS label including the added number of time slots to each of a plurality of ODUflex containers.
