“…The power balance is achieved by the flexible-grid attenuation capability of the SSSs. From the OSNR performance perspective, [18] concludes that the third method performs significantly better than the former two. On the other hand, [19] proposed OSNR-adaptive modulation format and symbol rate transmission techniques to improve capacity or spectral efficiency.…”

“…Finally, only two recent studies, to the best of the authors' knowledge, address functional programmable optical nodes and networks with a detailed physical layer modeling and analysis. On the one hand, [18] investigates Erbium-doped fiber amplifier (EDFA) placement for channel power balance of a standalone function programmable optical node but neglecting OSNR and power imbalance effects in network-wide scenarios. On the other hand, [19] studies OSNR-aware, modulation format and transmission rate adaptive techniques to improve capacity or spectrum usage without providing EDFA placement nor power balance details.…”

“…Moreover, it is essential to configure signal attenuation at each SSS in a per-channel basis to optimize OSNR performance and deliver minimum OSNR degradation and deviation across channels on different ports and light paths. Indeed, DEMUX and couplers used in [18] need to be replaced by SSSs to allow cross-connection reuse for multiple wavelength channels that have the same destination port. Furthermore, the SSSs can introduce granular power attenuation to each channel in the path besides the initial power loss of the components.…”

“…It is worthwhile to mention two related works. On the one hand, H. Yuan et al proposed and compared in [18] three predefined static methods for the EDFA placement in standalone AoD nodes. Specifically, SSSs replace couplers in the architecture to enable spectrum switching and EDFAs are placed account for optical amplification.…”

Function Programmable Optical Network has been recently proposed to enhance flexibility on optical transport based on Architectureon-Demand (AoD). The flexible synthesis of optical node architectures provided by AoD enables an open and disaggregated optical layer thanks to the available deep programmability. However, previous studies focus on how to synthesize a single node out of switching function blocks neglecting the optical signal-to-noise ratio (OSNR) impact, power imbalance effects due to diverse set of devices traversed per input-output configuration and network-wide implications. In this work, we present Optical Network-wide Function Synthesis (ONetFuS), an algorithm to compose AoD nodes that considers placement and configuration of both switches and amplifiers. ONeFuS minimizes OSNR degradation and deviation across channels and offers enhanced power balance performance. Moreover, ONetFuS addresses multiple-node scenarios to investigate cascading, transmission distance, and networking effects. We compare the number of optical crossconnections computed by our proposal against solutions in the literature. Results in network scenarios including number of components, power balance, OSNR variations and OSNR penalty reductions, prove the suitability of our proposed ONetFuS for Open and Function Programmable Optical Networks.

“…After that, (4) local per-node information is used to (5) execute AoD synthesis and (6) perform node evaluation. Steps (4) to (6) can be adapted to optimize scalability [3] or power balance [7]. Finally, (7) accounts for self-healing properties [4], number of WSSs employed [5] and total network power consumption [6].…”
