An optical circuit-switched network core has the potential to overcome the inherent
challenges of a conventional electrical packet-switched core of today's compute clusters. As …

Abstract Optical Network-on-Chip (ONoC) is an emerging chip-level optical interconnection
technology to realise high-performance and power-efficient inter-core communication for …

Multicast has long been a performance bottleneck for data centers. Traditional solutions
relying on IP multicast suffer from poor congestion control and loss recovery on the data …

One-to-many group communication is a performance bottleneck for high-performance data
center applications, due to sending massive data from one source to hundreds of receivers …

Interconnection networks arranged as k-ary n-trees or spines are widely used to build high-
performance computing clusters. Current blade-based technology allows the integration of …

Powerful computing systems interconnected via high-bandwidth wavelength division
multiplexing (WDM) fibers are becoming inevitable to meet the needs of emerging …

We present a control plane architecture to accelerate multicast and incast traffic delivery for
data-intensive applications in cluster-computing interconnection networks. The architecture …

Optical Network-on-Chip (ONoC) is emerging as a key on-chip communication architecture
for multiprocessor systems. While multicast communication commonly exists in various …

Optical Circuit Switches (OCS) are increasingly used in cluster networks due to their data
rate, energy and longevity advantages over electrical packet switches. Concurrently, an …

We present Elmo, a system that addresses the multicast scalability problem in multi-tenant
data centers. Modern cloud applications frequently exhibit one-to-many communication …
