We experimentally investigate a flow-controlled optical packet switch node operation. The distributed control and the nanosecond packet switching/retransmission allow a limited input buffer capacity to ensure packet loss <;10-5 for loads up to 0.5.
We consider optical switching architectures that allow for scaling to a large number of ports. We show that the complexity of the node control critically depends on the node architecture and impacts the end-to-end latency of the system. We introduce, node architectures with highly distributed control that allow for systems that introduce very low end-to-end latency.
This paper analyzes the performance of an optical packet switch architecture with highly distributed control, designed for interconnection of cluster switches in a simulated data center traffic environment. The system under development can be scaled up to a very large ports count, in the thousand order, enabling interconnection of a great number of servers. An important feature of this optical packet...
We investigate the performance of an optical packet switch architecture with highly distributed control for interconnecting cluster switches in a data center environment. The optical packet switch under investigation can be scaled to a very large port count to interconnect a large number of cluster switches. Flow control is employed to regulate the packets transmission between the electronic buffers...
We review our work on optical switching architectures that allow for scaling to a large number (thousands) of ports. We explain that the complexity of the node control critically depends on the node architecture and, hence, critically impacts the end-to-end latency of the system. We introduce node architectures with highly distributed control that allow for systems with very low end-to-end latency...
We demonstrate for the first time 40 Gb/s operation of a modular large port count optical packet switch with highly distributed control. The switch shows 25ns latency and record low energy consumption of 76.5 pj/bit.
We investigate the impact of switching architectures that scale to thousands of ingress and egress nodes on the node control. We give an example of an architecture that is highly scalable while supporting low latency
We demonstrate large-capacity high-resolution optical buffer, comprising 1 ?? 16 InP switch and ultra-compact delay lines based on thin-cladding highly nonlinear fibers. Silica-PLC-based pitch converter is employed to realize uniform coupling from all 16 switch ports simultaneously.
Optical signal processing for packet switching is discussed. Starting from a packet switch architecture implementations of photonic building blocks are discussed.
We investigate how much buffering is required in optical packet routers. In particular, we investigate how the buffering-depth scales with the number of ports of the router and how the packet loss and throughput depend on the network load.
