The paper presents an architectural framework integrating three aspects: a risk-diverse route-computation algorithm with shared-risk link group constraints that achieve polynomial complexity and overcome memory constraints. Secondly, it presents a self-optimising signal-control bus modelled as a closed-loop queueing system that maintains 95% throughput under an offered load of 400%, thereby representing a statistically significant improvement over static configurations. Lastly, it presents an adaptive multipath communication framework formalised as a multi-objective optimisation that enables application-specific trade-offs among reliability, latency, and bandwidth. Performance evaluation demonstrates polynomial versus exponential memory scaling, control-plane resilience under signalling storms, and sub-10 ms latency at 10% packet loss. As such, the discussed aspects establish design principles for reliable, resilient, and robust converged optical\u2013wireless networks. In addition to formal architectural modelling and algorithm design, this study independently validates the proposed framework through original simulations conducted in OMNeT++ and ns-3.<\/jats:p>","DOI":"10.3390\/s26092634","type":"journal-article","created":{"date-parts":[[2026,4,24]],"date-time":"2026-04-24T12:29:11Z","timestamp":1777033751000},"page":"2634","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Design of Reliable, Resilient, and Robust Architecture and Control for Next-Generation Optical\u2013Wireless Networks"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7252-2930","authenticated-orcid":false,"given":"Bakhe","family":"Nleya","sequence":"first","affiliation":[{"name":"Department of Electronic and Computer Engineering, Faculty of Engineering and the Built Environment, Durban University of Technology, Durban 4001, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Beverly","family":"Pule","sequence":"additional","affiliation":[{"name":"Department of Electronic and Computer Engineering, Faculty of Engineering and the Built Environment, Durban University of Technology, Durban 4001, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"158","DOI":"10.1109\/MCOM.001.2400517","article-title":"Resilient-by-Design: A Resilience Framework for Future Wireless Networks","volume":"63","author":"Mahmood","year":"2025","journal-title":"IEEE Commun.
