Dynamic routing, waveband, and spectrum assignment for optical superchannels in IP over multi-granular optical nodes
As capacity requirements in optical networks continue to grow, there is an increasing need for high-bandwidth optical fiber links. This has led to the use of Ultra-wideband (UWB) technology to utilize the unused optical spectrum for high-capacity data transmission. Another approach to enhancing capa...

| Sumario: | As capacity requirements in optical networks continue to grow, there is an increasing need for high-bandwidth optical fiber links. This has led to the use of Ultra-wideband (UWB) technology to utilize the unused optical spectrum for high-capacity data transmission. Another approach to enhancing capacity involves using multiple optical fibers per link. However, designing higher port count Wavelength Selective Switches (WSSs) for links with multiple fibers is costly and inefficient. To alleviate this, we explore IP over Multi-Granular-Optical Node (MG-ON) networks that incorporate waveband and wavelength layers, with Waveband Selective Switches (WBSSs) at the waveband physical layer and atop WSSs at the wavelength virtual layer. Furthermore, the need for high-line rate transmissions in the future is addressed by using the concept of optical superchannels in the MG-ON architecture. This paper introduces Routing, Waveband and Spectrum Assignment algorithms for MG-ON networks with high-capacity and high-line rate transmissions for various test cases. Additionally, we compare MG-ON performance with that of theoretical UWB-based WDM networks. © 2025 Elsevier B.V. |
