More Capacity from Less Spectrum: Tapping into Optical-Layer Intelligence in Optical Computing-Communication Integrated Network
Bibliographic record
Abstract
Optical fiber communications and networks constituting the backbone of Internet infrastructure have been continuing evolving technologically and architecturally to meet the explosive traffic growth. On the technological front, recent key advancements including spectrally and spatially flexible transmission, and wide-band optical transmission hold the promise of order-of-magnitude capacity gain. Concurrently, architectural innovations seek to capitalize on this expanded capacity to enable more scalable, cost-effective, and energy-efficient data transport. A prominent example is the optical-bypass architecture, which has now become widely deployed since the 2000s due to its substantial operational and capital cost savings over the predecessor optical-electrical-optical (O-E-O) mode. Driven by massive investments and consequently significant progresses in optical computing and all-optical signal processing technologies lately, this paper presents a new architectural paradigm for next-generation optical transport network, entitled optical computing-communication integrated network, which is capable of providing dual services at the optical layer, namely, computing and communication. This approach seeks to exploit the potential for performing optical computing operations among lightpaths that traverse the same intermediate node. Optical-Layer intelligence concept is thus introduced as the capability to perform computing / processing at the lightpath scale to achieve greater spectral and/or computing efficiency. A case study focusing on optical aggregation operation is introduced, highlighting the key differences between optical computing-communication integrated network and its current counterpart, optical-bypass ones. A mathematical formulation for optimal designs of optical-aggregation-enabled network is then provided and performance comparison with traditional optical-bypass model is drawn on the realistic NSFNET topology.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
