This thesis investigates the potential of a new generation of optical transceivers, ZR/ZR+ pluggables, to improve the energy efficiency of IP-over-Wavelength Division Multiplexing (IPoWDM) networks. ZR/ZR+ pluggables are designed for short-reach, high-bandwidth data transmission, and boast significantly lower power consumption compared to traditional long-haul muxponders. ZR/ZR+ has been shown to be more energy-efficient than long-haul muxponders for a static traffic matrix.

La crescita esplosiva del traffico dati richiede una continua espansione delle reti ottiche, spina dorsale della comunicazione globale. Tuttavia, il consumo energetico di queste reti è diventato una delle principali preoccupazioni. Questa tesi indaga il potenziale di una nuova generazione di ricetrasmettitori ottici, i plug-in ZR/ZR+, per migliorare l’efficienza energetica delle reti IP su Wavelength Division Multiplexing (IPoWDM). I plug-in ZR/ZR+ sono progettati per la trasmissione dati a corto raggio e a banda larga e vantano un consumo energetico significativamente inferiore rispetto ai ricetrasmettitori tradizionali a lunga distanza. ZR/ZR+ ha dimostrato di essere più efficiente dal punto di vista energetico rispetto ai muxponder a lungo raggio per una matrice di traffico statica. Tuttavia, non è chiaro se ZR/ZR+ mantenga ancora un vantaggio in termini di efficienza energetica rispetto ai muxponder a lungo raggio in condizioni di traffico variabile e riconfigurazione della rete. Confrontando il consumo energetico delle reti IPoWDM che utilizzano ottiche collegabili ZR/ZR+ con le reti che impiegano muxponder convenzionali a lungo raggio, questa ricerca indaga l’efficacia di diverse tecniche per ridurre il consumo energetico nelle reti WDM in condizioni dinamiche. Queste tecniche includono la riconfigurazione dei formati di modulazione e il reindirizzamento del traffico a livello IP o sia a livello IP che ottico. La valutazione considera due distinte configurazioni di rete: trasparente e opaca, attraverso varie topologie di rete. Analizzando i risultati, questa tesi si propone di valutare l’efficacia dei plug-in ZR/ZR+ come strategia per promuovere una progettazione di rete più efficiente dal punto di vista energetico. Questa ricerca ha il potenziale di fornire spunti preziosi per gli operatori di rete e i gestori di centri dati che cercano di ottimizzare la propria infrastruttura di rete sia per le prestazioni che per l’efficienza energetica.

Abstract
The explosive growth of data traffic necessitates the continuous expansion of optical networks, which are the backbone of global communication. However, the power consumption of these networks has become a major concern. This thesis investigates the potential of a new generation of optical transceivers, ZR/ZR+ pluggables, to improve the energy efficiency of IP-over-Wavelength Division Multiplexing (IPoWDM) networks. ZR/ZR+ pluggables are designed for short-reach, high-bandwidth data transmission, and boast significantly lower power consumption compared to traditional long-haul muxponders. ZR/ZR+ has been shown to be more energy-efficient than long-haul muxponders for a static traffic matrix. However, it remains unclear whether ZR/ZR+ still holds an energy efficiency advantage over long-haul muxponders under conditions of varying traffic and network re-configuration. By comparing the power consumption of IPoWDM networks using ZR/ZR+ pluggable optics with networks employing conventional long-haul muxponders, this research investigates the effectiveness of different techniques for reducing power consumption in WDM networks under dynamic conditions. These techniques include re-configuring modulation formats and traffic re-routing at the IP layer or both the IP and optical layers. The evaluation considers two distinct network architectures: transparent and opaque network architectures, across various network topologies. By analyzing the results, this thesis aims to evaluate the effectiveness of ZR/ZR+ pluggables as a strategy for promoting more energy-efficient network design under dynamic traffic conditions. This research has the potential to provide valuable insights for network operators seeking to optimize their network infrastructure for both performance and energy efficiency.File | Dimensione | Formato | |
