Resource usage in a multipath network

An apparatus to provide improved resource usage in a multipath network, the multipath network comprising a first network node arranged to communicate with a second network node, the first and second network nodes being connected by a first path and a second path, the first path using a first communications network and the second path using a second communications network, and whereby the first network node has a first mode of operation and a second mode of operation, such that in a first mode traffic between the first and second network nodes is transmitted over the first path and not the second path, and in a second mode traffic between the first and second network nodes is transmitted over the first path and the second path, the apparatus comprising:

• a processor;
• and
• memory, said memory containing instructions executable by said processor whereby said apparatus is operative to:
• start a timer when the demanded amount of traffic between the first and second network nodes exceeds a threshold value;
• and
• select the second mode of operation if the demanded amount of traffic exceeds the threshold value for the duration of the timer, wherein the total bandwidth available on the first path is periodically measured and the threshold value recalculated by the first network node after a measurement is taken.
