TLDR
Under a reasonable set of assumptions about optical technology, the results suggest that the unslotted link protocol should be the preferred approach to building the optical deflection-routing network.Abstract:
Deflection routing plays a prominent role in many optical network architectures, because it can be implemented with modest packet-buffering requirements. From the practical perspective, however, the implementation of deflection routing, which is normally based on global time slotting, might pose challenges. The authors develop approaches to the implementation of both slotted and unslotted deflection-routing optical networks. They analyse important tradeoffs that are inherent to the design of optical deflection-routing networks and compare the performance of slotted and unslotted networks. Under a reasonable set of assumptions about optical technology, the results suggest that the unslotted link protocol should be the preferred approach to building the optical deflection-routing network. >read more

DOS: a scalable optical switch for datacenters
TL;DR: The architecture and performance studies of Datacenter Optical Switch designed for scalable and high-throughput interconnections within a data center are discussed and it is shown that even with 2 to 4 wavelengths, the performance of DOS is significantly better than an electrical switch network based on state-of-the-art flattened butterfly topology.

Performance analysis of deflection routing in optical burst-switched networks
TL;DR: A variant of priority queuing model is proposed to approximate burst loss probability and the results show that the model provides an accurate estimation and evaluation of the performance of deflection routing in Arpanet-2 topology indicates thatdeflection routing evidently brings significant blocking performance gain.

Performance analysis of optical burst switched node with deflection routing
Abstract: As the optical network evolves from static long haul connection provider to an adaptive and "smart" backbone solution, optical burst switching (OBS) becomes an attractive scheme for its flexibility and efficiency. However, how to reduce data loss is a crucial issue in such an asynchronous and one-way reservation system. In this paper, we study one contention resolution strategy in OBS networks: deflection routing. We extend an existing work to provide approximate and accurate models for the data loss analysis of single OBS node with and without wavelength conversion capability. The accuracy of our models is evaluated by simulation results.
