Traffic requests are becoming more heterogeneous and dynamic causing the so-called spectrum fragmentation. We propose a reactive defragmentation algorithm to mitigate this issue which degrades the network performance. Three strategies are suggested to compact the spectrum comb, taking into account the minimization of the disrupted services and their reconfiguration times. An accurate Rerouting strategy allows the set-up of a higher amount of traffic, obtaining more capacitive networks.

Abstract
Traffic requests are becoming more heterogeneous and dynamic causing the so-called spectrum fragmentation. We propose a reactive defragmentation algorithm to mitigate this issue which degrades the network performance. Three strategies are suggested to compact the spectrum comb, taking into account the minimization of the disrupted services and their reconfiguration times. An accurate Rerouting strategy allows the set-up of a higher amount of traffic, obtaining more capacitive networks.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
