This paper proposes a new paradigm and strategy for resource management in optical networks considering that resources allocated to a user or service can be squatted in by third parties temporarily in order to provide support for emergency situations or allocate traffic from different priorities that experience a sudden increase of demanded resources in the network. We introduce the strategies of Soft Squatting and Hard Squatting. Moreover, we propose a model and a preliminary evaluation for fibre infrastructure sharing in all-optical networks using the proposed squatting strategies.
