In most cases defragmentation occurs, in elastic optical networks, in the links between the network’s nodes. In this article, defragmentation in an elastic optical network’s node is investigated. The W-S-W switching architecture has been used as a node. A short description of a purpose-built simulator is introduced. Several methods of defragmentation which are implemented in this simulator are described as well.
