DbOBS: dual buffered switch for variable optical bursts in future datacenters

Modern data-driven applications pose stringent requirements of high bandwidth, ultra-low-latency, low-powered, and scalable interconnections among switches routers in data-centers. To address these demands, electronic switching is not a viable choice due to bandwidth computing bottlenecks. Thus, researchers explored effective optical switch design principles for next-generation In switches, data aggregates the form bursts (OB) at ultra-high speeds. case OB contention, solutions are proposed by store as recirculating patterns fiber delay lines (FDL) with induced delay. However, variable burst length, it possible measure slot thus storage contending intermediate core switches. Motivated from aforementioned discussions, this paper, we propose DbOBS, that capable during contention slots. DbOBS estimates mean deviation length minimize loss. The considered validated through parameters like-burst estimation, over-reservation, waiting time. For network-layer simulations, poison arrivals packetized units. packets sent Monte-Carlo loss probability (BLP) estimated various input load conditions buffer sizes. achieves BLP order $$10^{-4}$$ $$\approx$$ 0.8, buffer-size 50, $$L=5$$ , outperforms traditional designs.
