We consider traffic scheduling in an N×N packet switch with an optical switch fabric, where the fabric requires a reconfiguration overhead to change its switch configurations. To provide 100% throughput with bounded packet delay, a speedup in the switch fabric is necessary to compensate for both the reconfiguration overhead and the inefficiency of the scheduling algorithm. In order to reduce th...

We built and evaluated a hybrid electrical-packet/optical-circuit network for datacenters using a 10 μs optical circuit switch using wavelength-selective switches based on binary MEMs. This network has the potential to support large-scale, dynamic datacenter workloads. © 2013 Optical Society of America OCIS codes: 060.4250, 060.4253,060.6718.

We describe the design and implementation of a high-bandwidth packet-switched optical interconnect for a shared-memory multipro-cessor with latency-hiding mechanisms. The network has a direct topology and uses deeection routing to resolve contention, obviating elastic buuers and reducing ight latency. Each node is itself a cache-coherent multiprocessor with local memory, hardware to support mul...

In this paper, we present the Tiny Tera: a small packet switch with an aggregate bandwidth of 320Gb/s. The Tiny Tera is a CMOS-based input-queued, fixed-size packet switch suitable for a wide range of applications such as a highperformance ATM switch, the core of an Internet router or as a fast multiprocessor interconnect. Using off-the-shelf technology, we plan to demonstrate that a very highb...

The current fast-growing Internet traffic is demanding more and more network capacity everyday. The concept of wavelength division multiplexing (WDM) has provided us an opportunity to multiply the network capacity. Current optical switching technologies allow us to rapidly deliver the enormous bandwidth of WDM networks. Photonic packet switching offers high speed, data rate and format transpare...

We present an optoelectronic self-routing packet switch for digital data commutation applications. The routing of the input data is determined by the optical decoding of the destination address coded in the packet header preceding the data bits. As proof of the operating principle, a one input 64 output demonstration system was built. The experiment is based on the association of

Optical Burst Switching (OBS) provides statistical multiplexing capabilities at the optical layer with relaxed hardware requirements when compared to optical packet switching. One of the open challenges of OBS is to assemble as many packets as possible in the same burst, while at the same time ensuring low latency of the transmitted packets. The authors propose the use of OBS to realize a geogr...

The PetaWeb, proposed for Next Generation Internet (NGI) infrastructures, is an innovative, geographically distributed, high-capacity switch architecture based on recent advances in optical and electronic switching technologies. The PetaWeb supports adaptive capacity allocation between edge modules for connectionless and connection-oriented traffic. This is achieved by the use of a rate-regulat...

Fast optical circuit switches with large port count will allow flexible bandwidth allocation in datacenter networks by augmenting electrical packet switching.
