Abstract

Date of Conference: 23-25 April 2014 Frequency slot width selection in flexi-grid optical networks refers to the process of online update of the slot width of the channel, according to time-varying traffic demands. Since slot width updates are associated with signaling costs, it is common to limit the rate of updates. In this article, we propose a model-free hysteresis-based slot width selection algorithm for flexi-grid optical networks. © 2014 IEEE.
